Asynchronous Python client for the open datasets of Zurich (Switzerland).
## About
A python package with which you can retrieve data from the Open Data Platform of Zurich via [their API][api]. This package was initially created to only retrieve parking data from the API, but the code base is made in such a way that it is easy to extend for other datasets from the same platform.
## Installation
```bash
pip install zurich
```
## Datasets
You can read the following datasets with this package:
- [Parking spaces for disabled / Behindertenparkplätze][disabled_parkings] (413 locations)
<details>
<summary>Click here to get more details</summary>
### Disabled parkings
| Variable | Type | Description |
| :------- | :--- | :---------- |
| `spot_id` | int | The ID of the parking spot |
| `address` | str | The address of the parking spot |
| `longitude` | float | The longitude of the parking spot |
| `latitude` | float | The latitude of the parking spot |
</details>
## Example
```python
import asyncio
from zurich import ODPZurich
async def main() -> None:
"""Show example on using the Open Data API client."""
async with ODPZurich() as client:
disabled_parkings = await client.disabled_parkings()
print(disabled_parkings)
if __name__ == "__main__":
asyncio.run(main())
```
## Use cases
[NIPKaart.nl][nipkaart]
A website that provides insight into where disabled parking spaces are, based
on data from users and municipalities. Operates mainly in the Netherlands, but
also has plans to process data from abroad.
## Contributing
This is an active open-source project. We are always open to people who want to
use the code or contribute to it.
We've set up a separate document for our
[contribution guidelines](CONTRIBUTING.md).
Thank you for being involved! :heart_eyes:
## Setting up development environment
This Python project is fully managed using the [Poetry][poetry] dependency
manager.
You need at least:
- Python 3.9+
- [Poetry][poetry-install]
Install all packages, including all development requirements:
```bash
poetry install
```
Poetry creates by default an virtual environment where it installs all
necessary pip packages, to enter or exit the venv run the following commands:
```bash
poetry shell
exit
```
Setup the pre-commit check, you must run this inside the virtual environment:
```bash
pre-commit install
```
*Now you're all set to get started!*
As this repository uses the [pre-commit][pre-commit] framework, all changes
are linted and tested with each commit. You can run all checks and tests
manually, using the following command:
```bash
poetry run pre-commit run --all-files
```
To run just the Python tests:
```bash
poetry run pytest
```

Zut
===
Reusable Python, Django and PostgreSql utilities.
## Install
From PyPI:
pip install zut
From Git, last version:
pip install git+https://gitlab.com/ipamo/zut.git@main
Use SSH instead of HTTPS url:
pip install git+ssh://[email protected]/ipamo/zut.git@main
Specific version, including extra dependencies:
pip install git+https://gitlab.com/ipamo/[email protected]#egg=zut[extra]
In a `requirements.txt` file, including extra dependencies:
zut[extra] @ git+https://gitlab.com/ipamo/[email protected]#egg=zut[extra]
## Dev quick start
Install Python, its packet manager (`pip`) and PostgreSql.
Under Linux, also install password manager `pass` (used as _credentials manager_).
Windows pre-requisites:
- Download [Python](https://www.python.org/downloads/) and install it.
- Download [PostgreSql](https://www.enterprisedb.com/downloads/postgres-postgresql-downloads), install it, and add binaries (`C:\Program Files\PostgreSQL\14\bin`) to PATH.
Linux (Debian) pre-requisites:
sudo apt install python3-venv python3-pip postgresql pass
Create Python virtual environment (example for Windows):
python -m venv .venv # Debian: python3 -m venv .venv
.\.venv\Scripts\activate # Linux: source .venv/bin/activate
pip install --upgrade pip setuptools wheel
pip install -r requirements.txt
Create test database (cf. parameters in `tests/settings.py`). Example:
sudo -u postgres psql -c "create database test_zut encoding 'utf8' template 'template0'"
For Linux, configure password manager `pass`. Example:
# Import your GPG key, show key identifier and mark key as trusted
gpg --import my-private-gpg-key.asc
gpg --list-secret-keys
gpg --edit-key [email protected]
trust
5
o
q
# Initialize "pass" with your GPG key
pass init [email protected]
Run tests:
python -m unittest
Run commands :
python -m zut --help
## Publish library
Configure `~/.pypirc`. Example:
```conf
[distutils]
index-servers =
pypi
testpypi
zut
[pypi]
username = __token__
password = # use project-scoped token instead
[testpypi]
# user-scoped token
username = __token__
password = pypi-xxxxx...
# -----------------------------------------------------------------------------
# Project-scoped token
# Usage example: twine --repository zut
#
[zut]
repository = https://upload.pypi.org/legacy/
username = __token__
password = pypi-xxxxx...
```
Prepare distribution:
pip install twine # if not already done
python -m zut checkversion
python tools.py clean
python setup.py sdist bdist_wheel
twine check dist/*
Upload tarball on PyPI:
# $env:HTTPS_PROXY="..." # if necessary
# $env:TWINE_CERT="C:\...\ca-certificates.crt" # if necessary
twine upload --repository zut dist/*

# zutilities
A collection of Python utilities
## Table of Contents
- [Prerequisites](#prerequisites)
- [Installation](#installation)
- [Usage](#usage)
- [License](#license)
## Prerequisites
You'll need to have Python installed in order to use `zutilities`. Start by downloading and installing [Python](https://www.python.org/downloads/).
> *Note: Python 3 is recommended, however `zutilities` will probably work just fine with most verions of Python 2*
## Installation
```
python -m pip install zutilities
```
## Usage
`zutilities`.**jprint**(list_or_dict, indent=2)
Prints a list or dictionary as formatted JSON.
```
>>> zutilities.jprint([{'key1':'value1','key2':'value2'}])
[
{
"key1": "value1",
"key2": "value2"
}
]
```
`zutilities`.**read_json_file**(json_file)
Reads a JSON file from the filesystem and returns a list or dictionary.
```
>>> j = zutilities.read_json_file('file.json')
>>> j
[{'key1': 'value1', 'key2': 'value2'}]
```
`zutilities`.**get_logger**(log_level=20, format=default_log_format, streams=[sys.stdout])
Returns a _logging.RootLogger_ object with preferred defaults set. The _default_log_format_ is '[%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s - %(message)s'
```
>>> logr = zutilities.get_logger()
>>> logr.info('Hello World')
[2021-10-08 21:08:40,353] {<stdin>:1} INFO - Hello world

# zuul-lint
## Validate from the command line
```
pip install zuul-lint
zuul-lint .zuul.yaml
```
## Validate with pre-commit
Add the code below to your `.pre-commit-config.yaml` file:
```yaml
- repo: https://github.com/pycontribs/zuul-lint.git
rev: "0.1"
hooks:
- id: zuul-lint
```
## Validate with VS Code
To ease editing Zuul CI configuration file we added experimental support for
a Zuul JSON Schema. This should enable validation and auto-completion in
code editors.
For example on [VSCode](1) you can use the [YAML](2) extension to use such a schema
validation by adding the following to `settings.json`:
```json
"yaml.schemas": {
"https://raw.githubusercontent.com/pycontribs/zuul-lint/master/zuul_lint/zuul-schema.json": ["*zuul.d/*.yaml", "*/.zuul.yaml"]
},
"yaml.customTags": [
"!encrypted/pkcs1-oaep array"
],
"sortJSON.orderOverride": ["title", "name", "$schema", "version", "description", "type"],
"sortJSON.orderUnderride": ["definitions"]
```

============
Testing Zuul
============
------------
A Quickstart
------------
This is designed to be enough information for you to run your first tests on
an Ubuntu 20.04 (or later) host.
*Install pip*::
sudo apt-get install python3-pip
More information on pip here: http://www.pip-installer.org/en/latest/
*Use pip to install tox*::
pip install tox
A running zookeeper is required to execute tests, but it also needs to be
configured for TLS and a certificate authority set up to handle socket
authentication. Because of these complexities, it's recommended to use a
helper script to set up these dependencies, as well as a database servers::
sudo apt-get install docker-compose # or podman-compose if preferred
ROOTCMD=sudo tools/test-setup-docker.sh
.. note:: Installing and bulding javascript is not required, but tests that
depend on the javascript assets having been built will be skipped
if you don't.
*Install javascript tools*::
tools/install-js-tools.sh
*Install javascript dependencies*::
pushd web
yarn install
popd
*Build javascript assets*::
pushd web
yarn build
popd
Run The Tests
-------------
*Navigate to the project's root directory and execute*::
tox
Note: completing this command may take a long time (depends on system resources)
also, you might not see any output until tox is complete.
Information about tox can be found here: http://testrun.org/tox/latest/
Run The Tests in One Environment
--------------------------------
Tox will run your entire test suite in the environments specified in the project tox.ini::
[tox]
envlist = <list of available environments>
To run the test suite in just one of the environments in envlist execute::
tox -e <env>
so for example, *run the test suite in py35*::
tox -e py35
Run One Test
------------
To run individual tests with tox::
tox -e <env> -- path.to.module.Class.test
For example, to *run a single Zuul test*::
tox -e py35 -- tests.unit.test_scheduler.TestScheduler.test_jobs_executed
To *run one test in the foreground* (after previously having run tox
to set up the virtualenv)::
.tox/py35/bin/stestr run tests.unit.test_scheduler.TestScheduler.test_jobs_executed
List Failing Tests
------------------
.tox/py35/bin/activate
stestr failing --list
Hanging Tests
-------------
The following will run each test in turn and print the name of the
test as it is run::
. .tox/py35/bin/activate
stestr run
You can compare the output of that to::
python -m testtools.run discover --list

:title: Vulnerability Reporting
.. _vulnerability-reporting:
Vulnerability Reporting
=======================
Zuul strives to be as secure as possible, implementing a layered
defense-in-depth approach where any untrusted code is executed and
leveraging well-reviewed popular libraries for its cryptographic
needs. Still, bugs are inevitable and security bugs are no exception
to that rule.
If you've found a bug in Zuul and you suspect it may compromise the
security of some part of the system, we'd appreciate the opportunity
to privately discuss the details before any suspected vulnerability
is made public. There are a couple possible ways you can bring
security bugs to our attention:
Create a Private Story in StoryBoard
------------------------------------
You can create a private story at the following URL:
`<https://storyboard.openstack.org/#!/story/new?force_private=true>`_
Using this particular reporting URL helps prevent you from
forgetting to set the ``Private`` checkbox in the new story UI
before saving. If you're doing this from a normal story creation
workflow instead, please make sure to set this checkbox first.
Enter a short but memorable title for your vulnerability report and
provide risks, concerns or other relevant details in the description
field. Where it lists teams and users that can see this story, add
the ``zuul-security`` team so they'll be able to work on triaging
it. For the initial task, select the project to which this is
specific (e.g., ``zuul/zuul`` or
``zuul/nodepool``) and if it relates to additional
projects you can add another task for each of them making sure to
include a relevant title for each task. When you've included all the
detail and tasks you want, save the new story and then you can
continue commenting on it normally. Please don't remove the
``Private`` setting, and instead wait for one of the zuul-security
reviewers to do this once it's deemed safe.
Report via Encrypted E-mail
---------------------------
If the issue is extremely sensitive or you’re otherwise unable to
use the task tracker directly, please send an E-mail message to one
or more members of the Zuul security team. You’re encouraged to
encrypt messages to their OpenPGP keys, which can be found linked
below and also on the keyserver network with the following
fingerprints:

:title: Project Gating
.. _project_gating:
Project Gating
==============
Traditionally, many software development projects merge changes from
developers into the repository, and then identify regressions
resulting from those changes (perhaps by running a test suite with a
continuous integration system), followed by more patches to fix those
bugs. When the mainline of development is broken, it can be very
frustrating for developers and can cause lost productivity,
particularly so when the number of contributors or contributions is
large.
The process of gating attempts to prevent changes that introduce
regressions from being merged. This keeps the mainline of development
open and working for all developers, and only when a change is
confirmed to work without disruption is it merged.
Many projects practice an informal method of gating where developers
with mainline commit access ensure that a test suite runs before
merging a change. With more developers, more changes, and more
comprehensive test suites, that process does not scale very well, and
is not the best use of a developer's time. Zuul can help automate
this process, with a particular emphasis on ensuring large numbers of
changes are tested correctly.
Testing in parallel
-------------------
A particular focus of Zuul is ensuring correctly ordered testing of
changes in parallel. A gating system should always test each change
applied to the tip of the branch exactly as it is going to be merged.
A simple way to do that would be to test one change at a time, and
merge it only if it passes tests. That works very well, but if
changes take a long time to test, developers may have to wait a long
time for their changes to make it into the repository. With some
projects, it may take hours to test changes, and it is easy for
developers to create changes at a rate faster than they can be tested
and merged.
Zuul's :value:`dependent pipeline manager<pipeline.manager.dependent>`
allows for parallel execution of test jobs for gating while ensuring
changes are tested correctly, exactly as if they had been tested one
at a time. It does this by performing speculative execution of test
jobs; it assumes that all jobs will succeed and tests them in parallel
accordingly. If they do succeed, they can all be merged. However, if
one fails, then changes that were expecting it to succeed are
re-tested without the failed change. In the best case, as many
changes as execution contexts are available may be tested in parallel
and merged at once. In the worst case, changes are tested one at a
time (as each subsequent change fails, changes behind it start again).
For example, if a reviewer approves five changes in rapid succession::
A, B, C, D, E
Zuul queues those changes in the order they were approved, and notes
that each subsequent change depends on the one ahead of it merging:
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
A <- B <- C <- D <- E;
}
Zuul then starts immediately testing all of the changes in parallel.
But in the case of changes that depend on others, it instructs the
test system to include the changes ahead of it, with the assumption
they pass. That means jobs testing change *B* include change *A* as
well::
Jobs for A: merge change A, then test
Jobs for B: merge changes A and B, then test
Jobs for C: merge changes A, B and C, then test
Jobs for D: merge changes A, B, C and D, then test
Jobs for E: merge changes A, B, C, D and E, then test
Hence jobs triggered to tests A will only test A and ignore B, C, D:
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
master -> A -> B -> C -> D -> E;
group jobs_for_A {
label = "Merged changes for A";
master -> A;
}
group ignored_to_test_A {
label = "Ignored changes";
color = "lightgray";
B -> C -> D -> E;
}
}
The jobs for E would include the whole dependency chain: A, B, C, D, and E.
E will be tested assuming A, B, C, and D passed:
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
group jobs_for_E {
label = "Merged changes for E";
master -> A -> B -> C -> D -> E;
}
}
If changes *A* and *B* pass tests (green), and *C*, *D*, and *E* fail (red):
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
A [color = lightgreen];
B [color = lightgreen];
C [color = pink];
D [color = pink];
E [color = pink];
master <- A <- B <- C <- D <- E;
}
Zuul will merge change *A* followed by change *B*, leaving this queue:
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
C [color = pink];
D [color = pink];
E [color = pink];
C <- D <- E;
}
Since *D* was dependent on *C*, it is not clear whether *D*'s failure is the
result of a defect in *D* or *C*:
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
C [color = pink];
D [label = "D\n?"];
E [label = "E\n?"];
C <- D <- E;
}
Since *C* failed, Zuul will report its failure and drop *C* from the queue,
keeping D and E:
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
D [label = "D\n?"];
E [label = "E\n?"];
D <- E;
}
This queue is the same as if two new changes had just arrived, so Zuul
starts the process again testing *D* against the tip of the branch, and
*E* against *D*:
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
master -> D -> E;
group jobs_for_D {
label = "Merged changes for D";
master -> D;
}
group ignored_to_test_D {
label = "Skip";
color = "lightgray";
E;
}
}
.. blockdiag::
blockdiag foo {
node_width = 40;
span_width = 40;
group jobs_for_E {
label = "Merged changes for E";
master -> D -> E;
}
}
Cross Project Testing
---------------------
When your projects are closely coupled together, you want to make sure
changes entering the gate are going to be tested with the version of
other projects currently enqueued in the gate (since they will
eventually be merged and might introduce breaking features).
Such relationships can be defined in Zuul configuration by placing
projects in a shared queue within a dependent pipeline. Whenever
changes for any project enter a pipeline with such a shared queue,
they are tested together, such that the commits for the changes ahead
in the queue are automatically present in the jobs for the changes
behind them. See :ref:`project` for more details.
A given dependent pipeline may have as many shared change queues as
necessary, so groups of related projects may share a change queue
without interfering with unrelated projects.
:value:`Independent pipelines <pipeline.manager.independent>` do
not use shared change queues, however, they may still be used to test
changes across projects using cross-project dependencies.
.. _dependencies:
Cross-Project Dependencies
--------------------------
Zuul permits users to specify dependencies across projects. Using a
special footer, users may specify that a change depends on another
change in any repository known to Zuul. In Gerrit based projects
this footer needs to be added to the git commit message. In GitHub
based projects this footer must be added to the pull request description.
Zuul's cross-project dependencies behave like a directed acyclic graph
(DAG), like git itself, to indicate a one-way dependency relationship
between changes in different git repositories. Change A may depend on
B, but B may not depend on A.
To use them, include ``Depends-On: <change-url>`` in the footer of a
commit message or pull request. For example, a change which depends
on a GitHub pull request (PR #4) might have the following footer::
Depends-On: https://github.com/example/test/pull/4
.. note::
For Github the ``Depends-On:`` footer must be in the *Pull Request*
description, which is separate and often different to the commit
message (i.e. the text submitted with ``git commit``). This is in
contrast to Gerrit where the change description is always the
commit message.
A change which depends on a Gerrit change (change number 3)::
Depends-On: https://review.example.com/3
Changes may depend on changes in any other project, even projects not
on the same system (i.e., a Gerrit change may depend on a GitHub pull
request).
.. note::
An older syntax of specifying dependencies using Gerrit change-ids
is still supported, however it is deprecated and will be removed in
a future version.
Dependent Pipeline
~~~~~~~~~~~~~~~~~~
When Zuul sees changes with cross-project dependencies, it serializes
them in the usual manner when enqueuing them into a pipeline. This
means that if change A depends on B, then when they are added to a
dependent pipeline, B will appear first and A will follow:
.. blockdiag::
:align: center
blockdiag crd {
orientation = portrait
span_width = 30
class greendot [
label = "",
shape = circle,
color = green,
width = 20, height = 20
]
A_status [ class = greendot ]
B_status [ class = greendot ]
B_status -- A_status
'Change B\nURL: .../4' <- 'Change A\nDepends-On: .../4'
}
If tests for B fail, both B and A will be removed from the pipeline, and
it will not be possible for A to merge until B does.
.. note::
If changes with cross-project dependencies do not share a change
queue then Zuul is unable to enqueue them together, and the first
will be required to merge before the second can be enqueued. If the
second change is approved before the first is merged, Zuul can't act
on the approval and won't automatically enqueue the second change,
requiring a new approval event to enqueue it after the first change
merges.
Independent Pipeline
~~~~~~~~~~~~~~~~~~~~
When changes are enqueued into an independent pipeline, all of the
related dependencies (both normal git-dependencies that come from
parent commits as well as cross-project dependencies) appear in a
dependency graph, as in a dependent pipeline. This means that even in
an independent pipeline, your change will be tested with its
dependencies. Changes that were previously unable to be fully tested
until a related change landed in a different repository may now be
tested together from the start.
All of the changes are still independent (you will note that the whole
pipeline does not share a graph as in a dependent pipeline), but for
each change tested, all of its dependencies are visually connected to
it, and they are used to construct the git repositories that Zuul uses
when testing.
When looking at this graph on the status page, you will note that the
dependencies show up as grey dots, while the actual change tested shows
up as red or green (depending on the jobs results):
.. blockdiag::
:align: center
blockdiag crdgrey {
orientation = portrait
span_width = 30
class dot [
label = "",
shape = circle,
width = 20, height = 20
]
A_status [class = "dot", color = green]
B_status [class = "dot", color = grey]
B_status -- A_status
"Change B\nURL: .../4" <- "Change A\nDepends-On: .../4"
}
This is to indicate that the grey changes are only there to establish
dependencies. Even if one of the dependencies is also being tested, it
will show up as a grey dot when used as a dependency, but separately and
additionally will appear as its own red or green dot for its test.
Multiple Changes
~~~~~~~~~~~~~~~~
A change may list more than one dependency by simply adding more
``Depends-On:`` lines to the commit message footer. It is possible
for a change in project A to depend on a change in project B and a
change in project C.
.. blockdiag::
:align: center
blockdiag crdmultichanges {
orientation = portrait
span_width = 30
class greendot [
label = "",
shape = circle,
color = green,
width = 20, height = 20
]
C_status [ class = "greendot" ]
B_status [ class = "greendot" ]
A_status [ class = "greendot" ]
C_status -- B_status -- A_status
A [ label = "Repo A\nDepends-On: .../3\nDepends-On: .../4" ]
group {
orientation = portrait
label = "Dependencies"
color = "lightgray"
B [ label = "Repo B\nURL: .../3" ]
C [ label = "Repo C\nURL: .../4" ]
}
B, C <- A
}
Cycles
~~~~~~
Zuul supports cycles that are created by use of cross-project dependencies.
However this feature is opt-in and can be configured on the queue.
See :attr:`queue.allow-circular-dependencies` for information on how to
configure this.
.. _global_repo_state:
Global Repo State
~~~~~~~~~~~~~~~~~
If a git repository is used by at least one job for a queue item, then
Zuul will freeze the repo state (i.e., branch heads and tags) and use
that same state for every job run for that queue item. Not every job
will get a git repo checkout of every repo, but for any repo that is
checked out, it will have the same state. Because of this, authors
can be sure that jobs running on the same queue item have a consistent
view of all involved git repos, even if one job starts running much
later than another.

:title: Project Configuration
.. _project-configuration:
Project Configuration
=====================
The following sections describe the main part of Zuul's configuration.
All of what follows is found within files inside of the repositories
that Zuul manages.
Security Contexts
-----------------
When a system administrator configures Zuul to operate on a project,
they specify one of two security contexts for that project. A
*config-project* is one which is primarily tasked with holding
configuration information and job content for Zuul. Jobs which are
defined in a config-project are run with elevated privileges, and all
Zuul configuration items are available for use. Base jobs (that is,
jobs without a parent) may only be defined in config-projects. It is
expected that changes to config-projects will undergo careful scrutiny
before being merged.
An *untrusted-project* is a project whose primary focus is not to
operate Zuul, but rather it is one of the projects being tested or
deployed. The Zuul configuration language available to these projects
is somewhat restricted (as detailed in individual sections below), and
jobs defined in these projects run in a restricted execution
environment since they may be operating on changes which have not yet
undergone review.
Configuration Loading
---------------------
When Zuul starts, it examines all of the git repositories which are
specified by the system administrator in :ref:`tenant-config` and
searches for files in the root of each repository. Zuul looks first
for a file named ``zuul.yaml`` or a directory named ``zuul.d``, and if
they are not found, ``.zuul.yaml`` or ``.zuul.d`` (with a leading
dot). In the case of an :term:`untrusted-project`, the configuration
from every branch is included, however, in the case of a
:term:`config-project`, only a single branch is examined.
The config project branch can be configured with the tenant configuration
:attr:`tenant.config-projects.<project>.load-branch` attribute.
When a change is proposed to one of these files in an
untrusted-project, the configuration proposed in the change is merged
into the running configuration so that any changes to Zuul's
configuration are self-testing as part of that change. If there is a
configuration error, no jobs will be run and the error will be
reported by any applicable pipelines. In the case of a change to a
config-project, the new configuration is parsed and examined for
errors, but the new configuration is not used in testing the change.
This is because configuration in config-projects is able to access
elevated privileges and should always be reviewed before being merged.
As soon as a change containing a Zuul configuration change merges to
any Zuul-managed repository, the new configuration takes effect
immediately.
.. _regex:
Regular Expressions
-------------------
Many options accept literal strings or regular expressions. In these
cases, the regular expression matching starts at the beginning of the
string as if there were an implicit ``^`` at the start of the regular
expression. To match at an arbitrary position, prepend ``.*`` to the
regular expression.
Zuul uses the `RE2 library <https://github.com/google/re2/wiki/Syntax>`_
which has a restricted regular expression syntax compared to PCRE.
.. _encryption:
Encryption
----------
Zuul supports storing encrypted data directly in the git repositories
of projects it operates on. If you have a job which requires private
information in order to run (e.g., credentials to interact with a
third-party service) those credentials can be stored along with the
job definition.
Each project in Zuul has its own automatically generated RSA keypair
which can be used by anyone to encrypt a secret and only Zuul is able
to decrypt it. Zuul serves each project's public key using its
build-in webserver. They can be fetched at the path
``/api/tenant/<tenant>/key/<project>.pub`` where ``<project>`` is the
canonical name of a project and ``<tenant>`` is the name of a tenant
with that project.
Zuul currently supports one encryption scheme, PKCS#1 with OAEP, which
can not store secrets longer than the 3760 bits (derived from the key
length of 4096 bits minus 336 bits of overhead). The padding used by
this scheme ensures that someone examining the encrypted data can not
determine the length of the plaintext version of the data, except to
know that it is not longer than 3760 bits (or some multiple thereof).
In the config files themselves, Zuul uses an extensible method of
specifying the encryption scheme used for a secret so that other
schemes may be added later. To specify a secret, use the
``!encrypted/pkcs1-oaep`` YAML tag along with the base64 encoded
value. For example:
.. code-block:: yaml
- secret:
name: test_secret
data:
password: !encrypted/pkcs1-oaep |
BFhtdnm8uXx7kn79RFL/zJywmzLkT1GY78P3bOtp4WghUFWobkifSu7ZpaV4NeO0s71YUsi
...
To support secrets longer than 3760 bits, the value after the
encryption tag may be a list rather than a scalar. For example:
.. code-block:: yaml
- secret:
name: long_secret
data:
password: !encrypted/pkcs1-oaep
- er1UXNOD3OqtsRJaP0Wvaqiqx0ZY2zzRt6V9vqIsRaz1R5C4/AEtIad/DERZHwk3Nk+KV
...
- HdWDS9lCBaBJnhMsm/O9tpzCq+GKRELpRzUwVgU5k822uBwhZemeSrUOLQ8hQ7q/vVHln
...
The `zuul-client utility <https://zuul-ci.org/docs/zuul-client/>`_ provides a
simple way to encrypt secrets for a Zuul project:
.. program-output:: zuul-client encrypt --help
.. _configuration-items:
Configuration Items
-------------------
The ``zuul.yaml`` and ``.zuul.yaml`` configuration files are
YAML-formatted and are structured as a series of items, each of which
is referenced below.
In the case of a ``zuul.d`` (or ``.zuul.d``) directory, Zuul recurses
the directory and extends the configuration using all the .yaml files
in the sorted path order. For example, to keep job's variants in a
separate file, it needs to be loaded after the main entries, for
example using number prefixes in file's names::
* zuul.d/pipelines.yaml
* zuul.d/projects.yaml
* zuul.d/01_jobs.yaml
* zuul.d/02_jobs-variants.yaml
Note subdirectories are traversed. Any subdirectories with a
``.zuul.ignore`` file will be pruned and ignored (this is facilitates
keeping playbooks or roles in the config directory, if required).
Below are references to the different configuration items you may use within
the YAML files:
.. toctree::
:maxdepth: 1
config/pipeline
config/job
config/project
config/queue
config/secret
config/nodeset

Glossary
========
.. glossary::
:sorted:
abstract job
A job which cannot be run directly, and is only intended to
serve as a parent on top of which other jobs are constructed.
artifact
A file or set of files created by a build and archived for
reuse. The term is usually in reference to primary build
outputs such as a release package or rendered documentation,
but can also mean files produced as a byproduct such as logs.
base job
A job with no parent. A base job may only be defined in a
:term:`config-project`. Multiple base jobs may be defined, but
each tenant has a single default job which will be used as the
parent of any job which does not specify one explicitly.
build
Any run of a job. Every build is assigned a globally unique
identifier which is used when coordinating between Zuul's
component services, and for purposes such as addressing log
streams and results in the status API and Web dashboard. The
context for a build comes not only from its job definition,
but also from the pipeline into which it is scheduled.
buildset
A collection of builds which share a common context. All
builds in a buildset have the same triggering event and change
identifier.
change
A specific state of a Git repository. Changes can represent a
change revision/pull request from a code review system, a
remote branch tip, a tag, or any other sort of Git ref. A
change can also come with additional dependency context,
either implicit from its commit history or explicit through
the use of cross-project dependency declarations (for example
in a commit message or pull request summary, the exact
mechanism varies by source connection driver).
child job
A job which inherits values such as playbooks and variables
from a parent job. All jobs are implicitly child jobs, since
they inherit from at least a base job whether they declare it
as a parent or not.
check
By convention, the name of a pipeline which performs pre-merge
tests. Such a pipeline might be triggered by creating a new
change or pull request. It may run with changes which have not
yet seen any human review, so care must be taken in selecting
the kinds of jobs to run, and what resources will be available
to them in order to avoid misuse of the system or credential
compromise. It usually has an :value:`independent
<pipeline.manager.independent>` pipeline manager since the final
sequence of changes to merge is not generally known at the time
of upload.
config-project
One of two types of projects which may be specified by the
administrator in the tenant config file. A config-project is
primarily tasked with holding configuration information and job
content for Zuul. Jobs which are defined in a config-project
are run with elevated privileges, and all Zuul configuration
items are available for use. It is expected that changes to
config-projects will undergo careful scrutiny before being
merged.
connection
A coupling of a triggering and reporting driver with
credentials and location information for a specific source of
events, whether that's a code review platform, a generic Git
hosting site or an emitting protocol such as SMTP or SQL.
cross-project dependency
An explicit declaration that a change depends on another
change, which need not be in the same Git repository or even
accessible via the same connection. Zuul is expected to
incorporate any cross-project dependencies into the context
for the change declaring that dependency relationship.
deploy
By convention, the name of a continuous-deployment pipeline.
Such a pipeline typically interacts with production systems
rather than ephemeral test nodes. By triggering on merge events
the results of deployment can be reported back to the
originating change. The :value:`serial
<pipeline.manager.serial>` pipeline manager, is recommended if
multiple repositories are involved and only some jobs (based on
file matchers) will be run for each change. If a single repo is
involved and all deployment jobs run on every change merged,
then :value:`supercedent <pipeline.manager.supercedent>` may be
a better fit.
executor
The component of Zuul responsible for executing a sandboxed
Ansible process in order to produce a build. Some builds may
run entirely in the executor's provided workspace if the job
is suitably constructed, or it may require the executor to
connect to remote nodes for more complex and risky operations.
final job
A job which no other jobs are allowed to use as a parent, for
example in order to prevent the list of tasks they run from
being altered by potential child jobs.
gate
By convention, the name of a pipeline which performs project
gating. Such a pipeline might be triggered by a core team
member approving a change or pull request. It should have a
:value:`dependent <pipeline.manager.dependent>` pipeline manager
so that it can combine and sequence changes as they are
approved.
inventory
The set of hosts and variable assignments Zuul provides to
Ansible, forming the context for a build.
job
A collection of Ansible playbooks, variables, filtering
conditions and other metadata defining a set of actions which
should be taken when invoked under the intended circumstances.
Jobs are anonymous sets of sequenced actions, which when
executed in the context of a pipeline, result in a build.
job dependency
A declared reliance in one job on the completion of builds for
one or more other jobs or provided artifacts those builds may
produce. Jobs may also be conditionally dependent on specific
build results for their dependencies.
job variant
A lightweight modification of another defined job altering
variables and filtering criteria.
merger
The component of Zuul responsible for constructing Git refs
provided to builds based on supplied change contexts from
triggering events. An executor may also be configured to run
a local merger process for increased efficiency.
node
A remote system resource on which Ansible playbooks may be
executed, for strong isolation from the executor's
environment. In Ansible inventory terms, this is a remote
host.
nodeset
An assembly of one or more nodes which, when applied in a job,
are added as host entries to the Ansible inventory for its
builds. Nodes in a nodeset can be given convenient names for
ease of reference in job playbooks.
parent job
A job from which a child job inherits values such as playbooks
and variables. Depending on the type of playbooks and
variables, these may either be merged with or overridden by
the child job. Any job which doesn't specify a parent
inherits from the tenant's base job.
pipeline
A set of triggering, prioritizing, scheduling, and reporting
rules which provide the context for a build.
pipeline manager
The algorithm through which a pipeline manages queuing of
trigger events. Specifically, this determines whether changes
are queued independently, sequenced together in the order
they're approved, or superceded entirely by subsequent events.
project
A unique Git source repository available through a connection
within a tenant. Projects are identified by their connection
or hostname, combined with their repository, so as to avoid
ambiguity when two repositories of the same name are available
through different connections.
project gating
Automatically preventing a proposed change from merging to a
canonical source code repository for a project until it is
able to pass declared tests for that repository. In a project
gating workflow, cues may be taken from its users, but it is
ultimately the gating system which controls merging of changes
and not the users themselves.
project pipeline
The application of jobs to a pipeline. Project pipeline
entries often include filtering and matching rules specifying
the conditions under which a job should result in a build, and
any interdependencies those jobs may have on the build results
and named artifacts provided by other jobs.
project queue
The set of changes sequenced for testing, either explicitly
through dependency relationships, or implicitly from the
chronological ordering of triggering events which enqueued
them. Project queues can be named and shared by multiple
projects, ensuring sequential merging of changes across those
projects.
project template
A named mapping of jobs into pipelines, for application to one
or more projects. This construct provides a convenient means
of reusing the same sets of jobs in the same pipelines across
multiple projects.
promote
By convention, the name of a pipeline which uploads previously
built artifacts. These artifacts should be constructed in a
:term:`gate` pipeline and uploaded to a temporary location.
When all of the jobs in the gate pipeline succeed, the change
will be merged and may then be enqueued into a promote pipeline.
Jobs running in this pipeline do so with the understanding that
since the change merged as it was tested in the gate, any
artifacts created at that time are now safe to promote to
production. It is a good choice to use a :value:`supercedent
<pipeline.manager.supercedent>` pipeline manager so that if many
changes merge in rapid sequence, Zuul may skip promoting all but
the latest artifact to production.
provided artifact
A named artifact which builds of a job are expected to
produce, for purposes of dependency declarations in other
jobs. Multiple jobs may provide equivalent artifacts with the
same name, allowing these relationships to be defined
independent of the specific jobs which provide them.
post
By convention, the name of a pipeline which runs after a branch
is updated. By triggering on a branch update (rather than a
merge) event, jobs in this pipeline may run with the final git
state after the merge (including any merge commits generated by
the upstream code review system). This is important when
building some artifacts in order that the exact commit ids are
present in the git repo. The downside to this approach is that
jobs in this pipeline run without any connection to the
underlying changes which created the commits. If only the
latest updates to a branch matter, then the :value:`supercedent
<pipeline.manager.supercedent>` pipeline manager is recommended;
otherwise :value:`independent <pipeline.manager.independent>`
may be a better choice. See also :term:`tag` and
:term:`release`.
release
By convention, the name of a pipeline which runs after a
release-formatted tag is updated. Other than the matching ref,
this is typically constructed the same as a :term:`post`
pipeline. See also :term:`tag`.
reporter
A reporter is a :ref:`pipeline attribute <reporters>` which
describes the action performed when an item is dequeued after
its jobs complete. Reporters are implemented by :ref:`drivers`
so their actions may be quite varied. For example, a reporter
might leave feedback in a remote system on a proposed change,
send email, or store information in a database.
required artifact
An artifact provided by one or more jobs, on which execution
of the job requiring it depends.
required project
A project whose source code is required by the job. Jobs
implicitly require the project associated with the event
which triggered their build, but additional projects can be
specified explicitly as well. Zuul supplies merge commits
representing the speculative future states of all required
projects for a build.
scheduler
The component of Zuul which coordinates source and reporting
connections as well as requests for nodes, mergers and
executors for builds triggered by pipeline definitions in the
tenant configuration.
speculative execution
A term borrowed from microprocessor design, the idea that
sequenced operations can be performed in parallel by
predicting their possible outcomes and then discarding any
logical branches which turn out not to be true. Zuul uses
optimistic prediction to assume all builds for a change will
succeed, and then proceeds to run parallel builds for other
changes which would follow it in sequence. If a change enters
a failing state (at least one of its voting builds indicates a
failure result), then Zuul resets testing for all subsequent
queue items to no longer include it in their respective
contexts.
tag
By convention, the name of a pipeline which runs after a tag is
updated. Other than the matching ref, this is typically
constructed the same as a :term:`post` pipeline. See also
:term:`release`.
tenant
A set of projects on which Zuul should operate. Configuration
is not shared between tenants, but the same projects from the
same connections may appear in more than one tenant and the
same events may even enqueue the same changes in pipelines for
more than one tenant. Zuul's HTTP API methods and Web
dashboard are scoped per tenant, in order to support distinct
tenant-specific authentication and authorization.
trigger
A (typically external) event which Zuul may rely on as a cue
to enqueue a change into a pipeline.
trusted execution context
Playbooks defined in a :term:`config-project` run in the
*trusted* execution context. The trusted execution context may
have access to extra directories within the bubblewrap container
if the operator has configured these.
untrusted execution context
Playbooks defined in an :term:`untrusted-project` run in the
*untrusted* execution context.
untrusted-project
One of two types of projects which may be specified by the
administrator in the tenant config file. An untrusted-project
is one whose primary focus is not to operate Zuul, but rather it
is one of the projects being tested or deployed. The Zuul
configuration language available to these projects is somewhat
restricted, and jobs defined in these projects run in a
restricted execution environment since they may be operating on
changes which have not yet undergone review.

:title: Tenant Configuration
.. _tenant-config:
Tenant Configuration
====================
After ``zuul.conf`` is configured, Zuul component servers will be able
to start, but a tenant configuration is required in order for Zuul to
perform any actions. The tenant configuration file specifies upon
which projects Zuul should operate. These repositories are grouped
into tenants. The configuration of each tenant is separate from the
rest (no pipelines, jobs, etc are shared between them).
A project may appear in more than one tenant; this may be useful if
you wish to use common job definitions across multiple tenants.
Actions normally available to the Zuul operator only can be performed by specific
users on Zuul's REST API if admin rules are listed for the tenant. Authorization rules
are also defined in the tenant configuration file.
The tenant configuration file is specified by the
:attr:`scheduler.tenant_config` setting in ``zuul.conf``. It is a
YAML file which, like other Zuul configuration files, is a list of
configuration objects, though only a few types of objects (described
below) are supported.
Alternatively the :attr:`scheduler.tenant_config_script`
can be the path to an executable that will be executed and its stdout
used as the tenant configuration. The executable must return a valid
tenant YAML formatted output.
Tenant configuration is checked for updates any time a scheduler is
started, and changes to it are read automatically. If the tenant
configuration is altered during operation, you can signal a scheduler
to read and apply the updated state in order to avoid restarting. See
the section on :ref:`reconfiguration` for instructions. Ideally,
tenant configuration deployment via configuration management should
also be made to trigger a smart-reconfigure once the file is replaced.
Tenant
------
A tenant is a collection of projects which share a Zuul
configuration. Some examples of tenant definitions are:
.. code-block:: yaml
- tenant:
name: my-tenant
max-nodes-per-job: 5
exclude-unprotected-branches: false
source:
gerrit:
config-projects:
- common-config
- shared-jobs:
include: job
untrusted-projects:
- zuul/zuul-jobs:
shadow: common-config
- project1
- project2:
exclude-unprotected-branches: true
.. code-block:: yaml
- tenant:
name: my-tenant
admin-rules:
- acl1
- acl2
source:
gerrit:
config-projects:
- common-config
untrusted-projects:
- exclude:
- job
- semaphore
- project
- project-template
- nodeset
- secret
projects:
- project1
- project2:
exclude-unprotected-branches: true
.. attr:: tenant
The following attributes are supported:
.. attr:: name
:required:
The name of the tenant. This may appear in URLs, paths, and
monitoring fields, and so should be restricted to URL friendly
characters (ASCII letters, numbers, hyphen and underscore) and
you should avoid changing it unless necessary.
.. attr:: source
:required:
A dictionary of sources to consult for projects. A tenant may
contain projects from multiple sources; each of those sources
must be listed here, along with the projects it supports. The
name of a :ref:`connection<connections>` is used as the
dictionary key (e.g. ``gerrit`` in the example above), and the
value is a further dictionary containing the keys below.
The next two attributes, **config-projects** and
**untrusted-projects** provide the bulk of the information for
tenant configuration. They list all of the projects upon which
Zuul will act.
The order of the projects listed in a tenant is important. A job
which is defined in one project may not be redefined in another
project; therefore, once a job appears in one project, a project
listed later will be unable to define a job with that name.
Further, some aspects of project configuration (such as the merge
mode) may only be set on the first appearance of a project
definition.
Zuul loads the configuration from all **config-projects** in the
order listed, followed by all **untrusted-projects** in order.
.. attr:: config-projects
A list of projects to be treated as :term:`config projects
<config-project>` in this tenant. The jobs in a config project
are trusted, which means they run with extra privileges, do not
have their configuration dynamically loaded for proposed
changes, and Zuul config files are only searched for in the
``master`` branch.
The items in the list follow the same format described in
**untrusted-projects**.
.. attr:: <project>
The config-projects have an additional config option that
may be specified optionally.
.. attr:: load-branch
:default: master
Define which branch is loaded from a config project. By
default config projects load Zuul configuration only
from the master branch.
.. attr:: untrusted-projects
A list of projects to be treated as untrusted in this tenant.
An :term:`untrusted-project` is the typical project operated on
by Zuul. Their jobs run in a more restrictive environment, they
may not define pipelines, their configuration dynamically
changes in response to proposed changes, and Zuul will read
configuration files in all of their branches.
.. attr:: <project>
The items in the list may either be simple string values of
the project names, or a dictionary with the project name as
key and the following values:
.. attr:: include
Normally Zuul will load all of the :ref:`configuration-items`
appropriate for the type of project (config or untrusted)
in question. However, if you only want to load some
items, the **include** attribute can be used to specify
that *only* the specified items should be loaded.
Supplied as a string, or a list of strings.
The following **configuration items** are recognized:
* pipeline
* job
* semaphore
* project
* project-template
* nodeset
* secret
.. attr:: exclude
A list of **configuration items** that should not be loaded.
.. attr:: shadow
Normally, only one project in Zuul may contain
definitions for a given job. If a project earlier in the
configuration defines a job which a later project
redefines, the later definition is considered an error and
is not permitted. The **shadow** attribute of a project
indicates that job definitions in this project which
conflict with the named projects should be ignored, and
those in the named project should be used instead. The
named projects must still appear earlier in the
configuration. In the example above, if a job definition
appears in both the ``common-config`` and ``zuul-jobs``
projects, the definition in ``common-config`` will be
used.
.. attr:: exclude-unprotected-branches
Define if unprotected branches should be processed.
Defaults to the tenant wide setting of
exclude-unprotected-branches. This currently only affects
GitHub and GitLab projects.
.. attr:: include-branches
A list of regexes matching branches which should be
processed. If omitted, all branches are included.
Operates after *exclude-unprotected-branches* and so may
be used to further reduce the set of branches (but not
increase it).
It has priority over *exclude-branches*.
.. attr:: exclude-branches
A list of regexes matching branches which should be
processed. If omitted, all branches are included.
Operates after *exclude-unprotected-branches* and so may
be used to further reduce the set of branches (but not
increase it).
It will not exclude a branch which already matched
*include-branches*.
.. attr:: always-dynamic-branches
A list of regular expressions matching branches which
should be treated as if every change newly proposes
dynamic Zuul configuration. In other words, the only time
Zuul will realize any configuration related to these
branches is during the time it is running jobs for a
proposed change.
This is potentially useful for situations with large
numbers of rarely used feature branches, but comes at the
cost of a significant reduction in Zuul features for these
branches.
Every regular expression listed here will also implicitly
be included in *exclude-branches*, therefore Zuul will not
load any static in-repo configuration from this branch.
These branches will not be available for use in overriding
checkouts of repos, nor will they be included in the git
repos that Zuul prepares for *required-projects* (unless
there is a change in the dependency tree for this branch).
In particular, this means that the only jobs which can be
specified for these branches are pre-merge and gating jobs
(such as :term:`check` and :term:`gate`). No post-merge
or periodic jobs will run for these branches.
Using this setting also incurs additional processing for
each change submitted for these branches as Zuul must
recalculate the configuration layout it uses for such a
change as if it included a change to a ``zuul.yaml`` file,
even if the change does not alter the configuration).
With all these caveats in mind, this can be useful for
repos with large numbers of rarely used branches as it
allows Zuul to omit their configuration in most
circumstances and only calculate the configuration of a
single additional branch when it is used.
.. attr:: implied-branch-matchers
This is a boolean, which, if set, may be used to enable
(``true``) or disable (``false``) the addition of implied
branch matchers to job and project-template definitions.
Normally Zuul decides whether to add these based on
heuristics described in :attr:`job.branches`. This
attribute overrides that behavior.
This can be useful if branch settings for this project may
produce an unpredictable number of branches to load from.
Setting this value explicitly here can avoid unexpected
behavior changes as branches are added or removed from the
load set.
The :attr:`pragma.implied-branch-matchers` pragma will
override the setting here if present.
Note that if a job contains an explicit branch matcher, it
will be used regardless of the value supplied here.
.. attr:: extra-config-paths
Normally Zuul loads in-repo configuration from the first
of these paths:
* zuul.yaml
* zuul.d/*
* .zuul.yaml
* .zuul.d/*
If this option is supplied then, after the normal process
completes, Zuul will also load any configuration found in
the files or paths supplied here. This can be a string or
a list. If a list of multiple items, Zuul will load
configuration from *all* of the items in the list (it will
not stop at the first extra configuration found).
Directories should be listed with a trailing ``/``. Example:
.. code-block:: yaml
extra-config-paths:
- zuul-extra.yaml
- zuul-extra.d/
This feature may be useful to allow a project that
primarily holds shared jobs or roles to include additional
in-repo configuration for its own testing (which may not
be relevant to other users of the project).
.. attr:: <project-group>
The items in the list are dictionaries with the following
attributes. A **configuration items** definition is applied
to the list of projects.
.. attr:: include
A list of **configuration items** that should be loaded.
.. attr:: exclude
A list of **configuration items** that should not be loaded.
.. attr:: projects
A list of **project** items.
.. attr:: max-nodes-per-job
:default: 5
The maximum number of nodes a job can request. A value of
'-1' value removes the limit.
.. attr:: max-job-timeout
:default: 10800
The maximum timeout for jobs. A value of '-1' value removes the limit.
.. attr:: exclude-unprotected-branches
:default: false
When using a branch and pull model on a shared repository
there are usually one or more protected branches which are gated
and a dynamic number of personal/feature branches which are the
source for the pull requests. These branches can potentially
include broken Zuul config and therefore break the global tenant
wide configuration. In order to deal with this Zuul's operations
can be limited to the protected branches which are gated. This
is a tenant wide setting and can be overridden per project.
This currently only affects GitHub and GitLab projects.
.. attr:: default-parent
:default: base
If a job is defined without an explicit :attr:`job.parent`
attribute, this job will be configured as the job's parent.
This allows an administrator to configure a default base job to
implement local policies such as node setup and artifact
publishing.
.. attr:: default-ansible-version
Default ansible version to use for jobs that doesn't specify a version.
See :attr:`job.ansible-version` for details.
.. attr:: allowed-triggers
:default: all connections
The list of connections a tenant can trigger from. When set, this setting
can be used to restrict what connections a tenant can use as trigger.
Without this setting, the tenant can use any connection as a trigger.
.. attr:: allowed-reporters
:default: all connections
The list of connections a tenant can report to. When set, this setting
can be used to restrict what connections a tenant can use as reporter.
Without this setting, the tenant can report to any connection.
.. attr:: allowed-labels
:default: []
The list of labels (as strings or :ref:`regular expressions <regex>`)
a tenant can use in a job's nodeset. When set, this setting can
be used to restrict what labels a tenant can use. Without this
setting, the tenant can use any labels.
.. attr:: disallowed-labels
:default: []
The list of labels (as strings or :ref:`regular expressions <regex>`)
a tenant is forbidden to use in a job's nodeset. When set, this
setting can be used to restrict what labels a tenant can use.
Without this setting, the tenant can use any labels permitted by
:attr:`tenant.allowed-labels`. This check is applied after the
check for `allowed-labels` and may therefore be used to further
restrict the set of permitted labels.
.. attr:: web-root
If this tenant has a whitelabeled installation of zuul-web, set
its externally visible URL here (e.g.,
``https://tenant.example.com/``). This will override the
:attr:`web.root` setting when constructing URLs for this tenant.
.. attr:: admin-rules
A list of authorization rules to be checked in order to grant
administrative access to the tenant through Zuul's REST API and
web interface.
At least one rule in the list must match for the user to be allowed to
execute privileged actions. A matching rule will also allow the user
access to the tenant in general (i.e., the rule does not need to be
duplicated in `access-rules`).
More information on tenant-scoped actions can be found in
:ref:`authentication`.
.. attr:: access-rules
A list of authorization rules to be checked in order to grant
read access to the tenant through Zuul's REST API and web
interface.
If no rules are listed, then anonymous access to the tenant is
permitted. If any rules are present then at least one rule in
the list must match for the user to be allowed to access the
tenant.
More information on tenant-scoped actions can be found in
:ref:`authentication`.
.. attr:: authentication-realm
Each authenticator defined in Zuul's configuration is associated to a realm.
When authenticating through Zuul's Web User Interface under this tenant, the
Web UI will redirect the user to this realm's authentication service. The
authenticator must be of the type ``OpenIDConnect``.
.. note::
Defining a default realm for a tenant will not invalidate
access tokens issued from other configured realms. This is
intended so that an operator can issue an overriding access
token manually. If this is an issue, it is advised to add
finer filtering to admin rules, for example, filtering by the
``iss`` claim (generally equal to the issuer ID).
.. attr:: semaphores
A list of names of :attr:`global-semaphore` objects to allow
jobs in this tenant to access.
.. _global_semaphore:
Global Semaphore
----------------
Semaphores are normally defined in in-repo configuration (see
:ref:`semaphore`), however to support use-cases where semaphores are
used to represent constrained global resources that may be used by
multiple Zuul tenants, semaphores may be defined within the main
tenant configuration file.
In order for a job to use a global semaphore, the semaphore must first
be defined in the tenant configuration file with
:attr:`global-semaphore` and then added to each tenant which should
have access to it with :attr:`tenant.semaphores`. Once that is done,
Zuul jobs may use that semaphore in the same way they would use a
normal tenant-scoped semaphore.
If any tenant which is granted access to a global semaphore also has a
tenant-scoped semaphore defined with the same name, that definition
will be treated as a configuration error and subsequently ignored in
favor of the global semaphore.
An example definition looks similar to the normal semaphore object:
.. code-block:: yaml
- global-semaphore:
name: global-semaphore-foo
max: 5
.. attr:: global-semaphore
The following attributes are available:
.. attr:: name
:required:
The name of the semaphore, referenced by jobs.
.. attr:: max
:default: 1
The maximum number of running jobs which can use this semaphore.
.. _authz_rule_definition:
Authorization Rule
------------------
An authorization rule is a set of conditions the claims of a user's
JWT must match in order to be allowed to perform actions at a tenant's
level.
When an authorization rule is included in the tenant's `admin-rules`,
the protected actions available are **autohold**, **enqueue**,
**dequeue** and **promote**.
.. note::
Rules can be overridden by the ``zuul.admin`` claim in a token if if matches
an authenticator configuration where `allow_authz_override` is set to true.
See :ref:`authentication` for more details.
Below are some examples of how authorization rules can be defined:
.. code-block:: yaml
- authorization-rule:
name: affiliate_or_admin
conditions:
- resources_access:
account:
roles: "affiliate"
iss: external_institution
- resources_access.account.roles: "admin"
- authorization-rule:
name: alice_or_bob
conditions:
- zuul_uid: alice
- zuul_uid: bob
Zuul previously used ``admin-rule`` for these definitions. That form
is still permitted for backwards compatibility, but is deprecated and
will be removed in a future version of Zuul.
.. attr:: authorization-rule
The following attributes are supported:
.. attr:: name
:required:
The name of the rule, so that it can be referenced in the ``admin-rules``
attribute of a tenant's definition. It must be unique.
.. attr:: conditions
:required:
This is the list of conditions that define a rule. A JWT must match **at
least one** of the conditions for the rule to apply. A condition is a
dictionary where keys are claims. **All** the associated values must
match the claims in the user's token; in other words the condition dictionary
must be a "sub-dictionary" of the user's JWT.
Zuul's authorization engine will adapt matching tests depending on the
nature of the claim in the token, eg:
* if the claim is a JSON list, check that the condition value is in the
claim
* if the claim is a string, check that the condition value is equal to
the claim's value
The claim names can also be written in the XPath format for clarity: the
condition
.. code-block:: yaml
resources_access:
account:
roles: "affiliate"
is equivalent to the condition
.. code-block:: yaml
resources_access.account.roles: "affiliate"
The special ``zuul_uid`` claim refers to the ``uid_claim`` setting in an
authenticator's configuration. By default it refers to the ``sub`` claim
of a token. For more details see the :ref:`authentication`.
Under the above example, the following token would match rules
``affiliate_or_admin`` and ``alice_or_bob``:
.. code-block:: javascript
{
'iss': 'external_institution',
'aud': 'my_zuul_deployment',
'exp': 1234567890,
'iat': 1234556780,
'sub': 'alice',
'resources_access': {
'account': {
'roles': ['affiliate', 'other_role']
}
},
}
And this token would only match rule ``affiliate_or_admin``:
.. code-block:: javascript
{
'iss': 'some_other_institution',
'aud': 'my_zuul_deployment',
'exp': 1234567890,
'sub': 'carol',
'iat': 1234556780,
'resources_access': {
'account': {
'roles': ['admin', 'other_role']
}
},
}
Authorization Rule Templating
-----------------------------
The special word "{tenant.name}" can be used in conditions' values. It will be automatically
substituted for the relevant tenant when evaluating authorizations for a given
set of claims. For example, consider the following rule:
.. code-block:: yaml
- authorization-rule:
name: tenant_in_groups
conditions:
- groups: "{tenant.name}"
If applied to the following tenants:
.. code-block:: yaml
- tenant:
name: tenant-one
admin-rules:
- tenant_in_groups
- tenant:
name: tenant-two
admin-rules:
- tenant_in_groups
Then this set of claims will be allowed to perform protected actions on **tenant-one**:
.. code-block:: javascript
{
'iss': 'some_other_institution',
'aud': 'my_zuul_deployment',
'exp': 1234567890,
'sub': 'carol',
'iat': 1234556780,
'groups': ['tenant-one', 'some-other-group'],
}
And this set of claims will be allowed to perform protected actions on **tenant-one**
and **tenant-two**:
.. code-block:: javascript
{
'iss': 'some_other_institution',
'aud': 'my_zuul_deployment',
'exp': 1234567890,
'sub': 'carol',
'iat': 1234556780,
'groups': ['tenant-one', 'tenant-two'],
}
API Root
--------
Most actions in zuul-web, zuul-client, and the REST API are understood
to be within the context of a specific tenant and therefore the
authorization rules specified by that tenant apply. When zuul-web is
deployed in a multi-tenant scenario (the default), there are a few
extra actions or API methods which are outside of the context of an
individual tenant (for example, listing the tenants or observing the
state of Zuul system components). To control access to these methods,
an `api-root` object can be used.
At most one `api-root` object may appear in the tenant configuration
file. If more than one appears, it is an error. If there is no
`api-root` object, then anonymous read-only access to the tenant list
and other root-level API methods is assumed.
The ``/api/info`` endpoint is never protected by Zuul since it
supplies the authentication information needed by the web UI.
API root access is not a pre-requisite to access tenant-specific URLs.
.. attr:: api-root
The following attributes are supported:
.. attr:: authentication-realm
Each authenticator defined in Zuul's configuration is associated
to a realm. When authenticating through Zuul's Web User
Interface at the multi-tenant root, the Web UI will redirect the
user to this realm's authentication service. The authenticator
must be of the type ``OpenIDConnect``.
.. note::
Defining a default realm for the root API will not invalidate
access tokens issued from other configured realms. This is
intended so that an operator can issue an overriding access
token manually. If this is an issue, it is advised to add
finer filtering to admin rules, for example, filtering by the
``iss`` claim (generally equal to the issuer ID).
.. attr:: access-rules
A list of authorization rules to be checked in order to grant
read access to the top-level (i.e., non-tenant-specific) portion
of Zuul's REST API and web interface.
If no rules are listed, then anonymous access to top-level
methods is permitted. If any rules are present then at at least
one rule in the list must match for the user to be allowed
access.
More information on tenant-scoped actions can be found in
:ref:`authentication`.

Troubleshooting
---------------
In addition to inspecting :ref:`service debug logs <operation>`, some
advanced troubleshooting options are provided below. These are
generally very low-level and are not normally required.
Thread Dumps and Profiling
==========================
If you send a SIGUSR2 to one of the daemon processes, it will dump a
stack trace for each running thread into its debug log. It is written
under the log bucket ``zuul.stack_dump``. This is useful for tracking
down deadlock or otherwise slow threads::
sudo kill -USR2 `cat /var/run/zuul/executor.pid`
view /var/log/zuul/executor-debug.log +/zuul.stack_dump
When `yappi <https://code.google.com/p/yappi/>`_ (Yet Another Python
Profiler) is available, additional functions' and threads' stats are
emitted as well. The first SIGUSR2 will enable yappi, on the second
SIGUSR2 it dumps the information collected, resets all yappi state and
stops profiling. This is to minimize the impact of yappi on a running
system.

.. _components:
Zuul is a distributed system consisting of several components, each of
which is described below.

}
.. contents::
:depth: 1
:local:
:backlinks: none
Each of the Zuul processes may run on the same host, or different
hosts.
Zuul requires an external ZooKeeper cluster running at least ZooKeeper
version 3.5.1, and all Zuul and Nodepool components need to be able to
connect to the hosts in that cluster on a TLS-encrypted TCP port,
typically 2281.
Both the Nodepool launchers and Zuul executors need to be able to
communicate with the hosts which Nodepool provides. If these are on
private networks, the executors will need to be able to route traffic
to them.
Only Zuul fingergw and Zuul web need to be publicly accessible;
executors never do. Executors should be accessible on TCP port 7900 by
fingergw and web.
A database is required and configured in ``database`` section of
``/etc/zuul/zuul.conf``. Both Zuul scheduler and Zuul web will need
access to it.
If statsd is enabled, the executors and schedulers need to be able to
emit data to statsd. Statsd can be configured to run on each host and
forward data, or services may emit to a centralized statsd collector.
Statsd listens on UDP port 8125 by default.
A minimal Zuul system may consist of a :ref:`scheduler` and
:ref:`executor` both running on the same host. Larger installations
should consider running multiple schedulers, executors and mergers,
with each component running on a dedicated host.

Installation
============
External Dependencies
---------------------
Zuul interacts with several other systems described below.
Nodepool
~~~~~~~~
In order to run all but the simplest jobs, Zuul uses a companion
program `Nodepool <https://opendev.org/zuul/nodepool>`__ to supply the
nodes (whether dynamic cloud instances or static hardware) used by
jobs. Before starting Zuul, ensure you have Nodepool installed and
any images you require built.
Zuul must be able to log into the nodes provisioned by Nodepool with a
given username and SSH private key. Executors should also be able to
talk to nodes on TCP port 19885 for log streaming; see
:ref:`nodepool_console_streaming`.
ZooKeeper
~~~~~~~~~
.. TODO: SpamapS any zookeeper config recommendations?
Zuul and Nodepool use ZooKeeper to communicate internally among their
components, and also to communicate with each other. You can run a
simple single-node ZooKeeper instance, or a multi-node cluster.
Ensure that all Zuul and Nodepool hosts have access to the cluster.
Zuul stores all possible state within ZooKeeper so that it can be
effectively shared and coordinated between instances of its component
services. Most of this is ephemeral and can be recreated or is of low
value if lost, but a clustered deployment will provide improved
continuity and resilience in the event of an incident adversely
impacting a ZooKeeper server.
Zuul's keystore (project-specific keys for asymmetric encryption of
job secrets and SSH access) is also stored in ZooKeeper, and unlike
the other data it **cannot be recreated** if lost. As such,
periodic :ref:`export and backup <backup>` of these keys is strongly
recommended.
.. _ansible-installation-options:
Executor Deployment
-------------------
The Zuul executor requires Ansible to run jobs. There are two
approaches that can be used to install Ansible for Zuul.
First you may set ``manage_ansible`` to True in the executor config. If you
do this Zuul will install all supported Ansible versions on zuul-executor
startup. These installations end up in Zuul's state dir,
``/var/lib/zuul/ansible-bin`` if unchanged.
The second option is to use ``zuul-manage-ansible`` to install the supported
Ansible versions. By default this will install Ansible to
``zuul_install_prefix/lib/zuul/ansible``. This method is preferable to the
first because it speeds up zuul-executor start time and allows you to
preinstall ansible in containers (avoids problems with bind mounted zuul
state dirs).
.. program-output:: zuul-manage-ansible -h
In both cases if using a non default path you will want to set
``ansible_root`` in the executor config file.
.. _web-deployment-options:
Web Deployment
--------------
The ``zuul-web`` service provides a web dashboard, a REST API and a websocket
log streaming service as a single holistic web application. For production use
it is recommended to run it behind a reverse proxy, such as Apache or Nginx.
The ``zuul-web`` service is entirely self-contained and can be run
with minimal configuration, however, more advanced users may desire to
do one or more of the following:
White Label
Serve the dashboard of an individual tenant at the root of its own domain.
https://zuul.openstack.org is an example of a Zuul dashboard that has been
white labeled for the ``openstack`` tenant of its Zuul.
Static Offload
Shift the duties of serving static files, such as HTML, Javascript, CSS or
images to the reverse proxy server.
Static External
Serve the static files from a completely separate location that does not
support programmatic rewrite rules such as a Swift Object Store.
Sub-URL
Serve a Zuul dashboard from a location below the root URL as part of
presenting integration with other application.
https://softwarefactory-project.io/zuul/ is an example of a Zuul dashboard
that is being served from a Sub-URL.
Most deployments shouldn't need these, so the following discussion
will assume that the ``zuul-web`` service is exposed via a reverse
proxy. Where rewrite rule examples are given, they will be given with
Apache syntax, but any other reverse proxy should work just fine.
Reverse Proxy
~~~~~~~~~~~~~
Using Apache as the reverse proxy requires the ``mod_proxy``,
``mod_proxy_http`` and ``mod_proxy_wstunnel`` modules to be installed
and enabled.
All of the cases require a rewrite rule for the websocket streaming, so the
simplest reverse-proxy case is::
RewriteEngine on
RewriteRule ^/api/tenant/(.*)/console-stream ws://localhost:9000/api/tenant/$1/console-stream [P]
RewriteRule ^/(.*)$ http://localhost:9000/$1 [P]
This is the recommended configuration unless one of the following
features is required.
Static Offload
~~~~~~~~~~~~~~
To have the reverse proxy serve the static html/javascript assets
instead of proxying them to the REST layer, enable the ``mod_rewrite``
Apache module, register the location where you unpacked the web
application as the document root and add rewrite rules::
<Directory /usr/share/zuul>
Require all granted
</Directory>
Alias / /usr/share/zuul/
<Location />
RewriteEngine on
RewriteBase /
# Rewrite api to the zuul-web endpoint
RewriteRule api/tenant/(.*)/console-stream ws://localhost:9000/api/tenant/$1/console-stream [P,L]
RewriteRule api/(.*)$ http://localhost:9000/api/$1 [P,L]
# Backward compatible rewrite
RewriteRule t/(.*)/(.*).html(.*) /t/$1/$2$3 [R=301,L,NE]
# Don't rewrite files or directories
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html [L]
</Location>
Sub directory serving
~~~~~~~~~~~~~~~~~~~~~
The web application needs to be rebuilt to update the internal location of
the static files. Set the homepage setting in the package.json to an
absolute path or url. For example, to deploy the web interface through a
'/zuul/' sub directory:
.. note::
The web dashboard source code and package.json are located in the ``web``
directory. All the yarn commands need to be executed from the ``web``
directory.
.. code-block:: bash
sed -e 's#"homepage": "/"#"homepage": "/zuul/"#' -i package.json
yarn build
Then assuming the web application is unpacked in /usr/share/zuul,
enable the ``mod_rewrite`` Apache module and add the following rewrite
rules::
<Directory /usr/share/zuul>
Require all granted
</Directory>
Alias /zuul /usr/share/zuul/
<Location /zuul>
RewriteEngine on
RewriteBase /zuul
# Rewrite api to the zuul-web endpoint
RewriteRule api/tenant/(.*)/console-stream ws://localhost:9000/api/tenant/$1/console-stream [P,L]
RewriteRule api/(.*)$ http://localhost:9000/api/$1 [P,L]
# Backward compatible rewrite
RewriteRule t/(.*)/(.*).html(.*) /t/$1/$2$3 [R=301,L,NE]
# Don't rewrite files or directories
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /zuul/index.html [L]
</Location>
White Labeled Tenant
~~~~~~~~~~~~~~~~~~~~
Running a white-labeled tenant is similar to the offload case, but adds a
rule to ensure connection webhooks don't try to get put into the tenant scope.
.. note::
It's possible to do white-labeling without static offload, but it
is more complex with no benefit.
Enable the ``mod_rewrite`` Apache module, and assuming the Zuul tenant
name is ``example``, the rewrite rules are::
<Directory /usr/share/zuul>
Require all granted
</Directory>
Alias / /usr/share/zuul/
<Location />
RewriteEngine on
RewriteBase /
# Rewrite api to the zuul-web endpoint
RewriteRule api/connection/(.*)$ http://localhost:9000/api/connection/$1 [P,L]
RewriteRule api/console-stream ws://localhost:9000/api/tenant/example/console-stream [P,L]
RewriteRule api/(.*)$ http://localhost:9000/api/tenant/example/$1 [P,L]
# Backward compatible rewrite
RewriteRule t/(.*)/(.*).html(.*) /t/$1/$2$3 [R=301,L,NE]
# Don't rewrite files or directories
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html [L]
</Location>
Static External
~~~~~~~~~~~~~~~
.. note::
Hosting the Zuul dashboard on an external static location that does
not support dynamic url rewrite rules only works for white-labeled
deployments.
In order to serve the zuul dashboard code from an external static location,
``REACT_APP_ZUUL_API`` must be set at javascript build time:
.. code-block:: bash
REACT_APP_ZUUL_API='http://zuul-web.example.com' yarn build

:title: Authenticated Actions
.. _authentication:
Authenticated Access
====================
Access to Zuul's REST API and web interface can optionally be
restricted. By default, anonymous read access to any tenant is
permitted. Optionally, some administrative actions may also be
enabled and restricted to authorized users. Additionally, individual
tenants or the entire system may have read-level access restricted
to authorized users.
The supported administrative actions are **autohold**,
**enqueue/enqueue-ref**, **dequeue/dequeue-ref** and
**promote**. These are similar to the ones available through
Zuul's CLI.
The protected endpoints require a bearer token, passed to Zuul Web
Server as the **Authorization** header of the request. The token and
this workflow follow the JWT standard as established in this `RFC
<https://tools.ietf.org/html/rfc7519>`_.
Important Security Considerations
---------------------------------
Anybody with a valid administrative token can perform privileged
actions exposed through the REST API. Furthermore revoking tokens,
especially when manually issued, is not trivial.
As a mitigation, tokens should be generated with a short time to
live, like 10 minutes or less. If the token contains authorization Information
(see the ``zuul.admin`` claim below), it should be generated with as little a scope
as possible (one tenant only) to reduce the surface of attack should the
token be compromised.
Exposing administration tasks can impact build results (dequeue-ing buildsets),
and pose potential resources problems with Nodepool if the ``autohold`` feature
is abused, leading to a significant number of nodes remaining in "hold" state for
extended periods of time. As always, "with great power comes great responsibility"
and tokens should be handed over with discernment.
Configuration
-------------
.. important:: In order to use restricted commands in the zuul command
line interface, at least one HS256 authenticator should
be configured.
To enable tenant-scoped access to privileged actions or restrict
read-level access, see the Zuul Web Server component's section.
To set access rules for a tenant, see :ref:`the documentation about tenant
definition <authz_rule_definition>`.
Most of the time, only one authenticator will be needed in Zuul's configuration;
namely the configuration matching a third party identity provider service like
dex, auth0, keycloak or others. It can be useful however to add another
authenticator similar to this one:
.. code-block:: ini
[auth zuul_operator]
driver=HS256
allow_authz_override=true
realm=zuul.example.com
client_id=zuul.example.com
issuer_id=zuul_operator
secret=exampleSecret
With such an authenticator, a Zuul operator can use Zuul's CLI to
issue tokens overriding a tenant's access rules if need
be. A user can then use these tokens with Zuul's CLI to perform protected actions
on a tenant temporarily, without having to modify a tenant's access rules.
.. _jwt-format:
JWT Format
----------
Zuul can consume JWTs with the following minimal set of claims:
.. code-block:: javascript
{
'iss': 'jwt_provider',
'aud': 'my_zuul_deployment',
'exp': 1234567890,
'iat': 1234556780,
'sub': 'alice'
}
* **iss** is the issuer of the token. It can be used to filter
Identity Providers.
* **aud**, as the intended audience, is usually the client id as registered on
the Identity Provider.
* **exp** is the token's expiry timestamp.
* **iat** is the token's date of issuance timestamp.
* **sub** is the default, unique identifier of the user.
JWTs can be extended arbitrarily with other claims. Zuul however can look for a
specific **zuul** claim, if the ``allow_authz_override`` option was set to True
in the authenticator's configuration. This claim has the following format:
.. code-block:: javascript
{
'zuul': {
'admin': ['tenant-one', 'tenant-two']
}
}
The **admin** field is a list of tenants on which the token's bearer is granted
the right to perform privileged actions.
Manually Generating a JWT
-------------------------
An operator can generate a JWT by using the settings of a configured authenticator
in ``zuul.conf``.
For example, in Python, and for an authenticator using the ``HS256`` algorithm:
.. code-block:: python
>>> import jwt
>>> import time
>>> jwt.encode({'sub': 'user1',
'iss': <issuer_id>,
'aud': <client_id>,
'iat': int(time.time()),
'exp': int(time.time()) + 300,
'zuul': {
'admin': ['tenant-one']
}
}, <secret>, algorithm='HS256')
'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ6dXVsIjp7ImFkbWluIjpbInRlbmFudC1vbmUiXX0sInN1YiI6InZlbmttYW4iLCJpc3MiOiJtYW51YWwiLCJleHAiOjE1NjAzNTQxOTcuMTg5NzIyLCJpYXQiOjE1NjAzNTM4OTcuMTg5NzIxLCJhdWQiOiJ6dXVsIn0.Qqb-ANmYv8slNUVSqjCJDL8HlH9L7nnLtLU2HBGzQJk'
Online resources like https://jwt.io are also available to generate, decode and
debug JWTs.
Debugging
---------
If problems appear:
* Make sure your configuration is correct, especially callback URIs.
* More information can be found in Zuul's web service logs.
* From the user's side, activating the web console in the browser can be helpful
to debug API calls.
Interfacing with Other Systems
------------------------------
Here are some how-tos to help administrators enable OpenID Connect
authentication in Zuul and Zuul's Web UI.

Upgrading
=========
Rolling Upgrades
----------------
If more than one of each Zuul component is present in a system, then
Zuul may be upgrading without downtime by performing a rolling
upgrade. During a rolling upgrade, components are stopped and started
one at a time until all components are upgraded. If there is a
behavior change during an upgrade, Zuul will typically wait until all
components are upgraded before changing behavior, but in some cases
when it is deemed safe, new behaviors may start to appear as soon as
the first component is upgraded. Be sure not to begin using or rely
on new behaviors until all components are upgraded.
Unless specified in the release notes, there is no specific order for
which components should be upgraded first, but the following order is
likely to produce the least disruption and delay the use of new
behaviors until closer to the end of the process:
* Gracefully restart executors (one at a time, or as many as a
system's over-allocation of resources will allow).
* Gracefully restart mergers.
* Restart schedulers.
* Restart web and finger gateways.
Skipping Versions
-----------------
Zuul versions are specified as `major.minor.micro`. In general,
skipping minor or micro versions during upgrades is considered safe.
Skipping major versions is not recommended, as backwards compatibility
code for older systems may be removed during a major upgrade. This
means that, for example, an upgrade from 5.x.y to 7.0.0 should include
at least an upgrade to 6.4.0 (the latest 6.x release) before
proceeding to 7.0.0.
If skipping major versions is required, then a rolling upgrade is not
possible, and Zuul should be completely stopped, and the ``zuul-admin
delete-state`` command should be run before restarting on the new
version.
Some versions may have unique upgrade requirements. See release notes
for additional information about specific version upgrades.

Zuul Project Governance
=======================
The governance of the Zuul project is described below. Changes to
this page should remain open for a week and require more positive than
negative Code-Review votes from the Maintainers before merging. They
should only be approved by the Project Lead.
Zuul Maintainers
----------------
The Zuul project is self-governed.
Decisions regarding the project are made by the Zuul Maintainers.
They are a team of people who are familiar with the project as a whole
and act as stewards of the project. They have the right to approve or
reject proposed changes to the codebase, as well as make other
decisions regarding the project.
The Maintainers are expected to be familiar with the source code,
design, operation, and usage of all parts of the Zuul project. When
acting in their capacity as Maintainers, they are expected to consider
not only their own needs, but those of the entire community.
Changes to the code, documentation, website, and other project
resources held in version control repositories are reviewed and
approved by the Maintainers. In general, approval is sought from at
least two maintainers before merging a change, but fewer or more
reviews may be warranted depending on the change. Factors to consider
when reviewing are the complexity of the change, whether it is in
accordance with the project design, and whether additional project
participants with subject matter expertise should review the change.
Maintainers may also reject changes outright, but this is expected to
be used sparingly in favor of (or in the process of) redirecting
effort toward efforts which can achieve consensus.
The purpose of this review process is two-fold: first, to ensure that
changes to the project meet sufficiently high standards so that they
improve the project, contribute to furthering its goals, and do not
introduce regressive behavior or make the project more difficult to
support in the future. Secondly, and just as important, the process
also ensures that contributors are aware of the changes to the
project. In a distributed environment, reviews are an important part
of our collaborative process.
Project decisions other than those involving on-line review are
discussed on the project mailing list. Anyone is welcome and
encouraged to participate in these discussions so that input from the
broader community is received. As the authority, Maintainers should
strive to achieve consensus on any such decisions.
Changes to the membership of the Maintainers are decided by consensus
of the existing maintainers, however, due to their sensitivity, these
discussions should occur via private communication among the
maintainers under the direction of the Project Lead.
A large group of Maintainers is important for the health of the
project, therefore contributors are encouraged to become involved in
all facets of maintenance of the project as part of the process of
becoming a Maintainer. Existing Maintainers are expected to encourage
new members. There are no artificial limits of the number of
Maintainers. The Project Lead will assist any contributor who wishes
for guidance in becoming a Maintainer.

Zuul Project Lead
-----------------
The Maintainers elect a Project Lead to articulate the overall
direction of the project and promote consistency among the different
areas and aspects of the project. The Project Lead does not have
extra rights beyond those of the Maintainers, but does have extra
responsibilities. The Project Lead must pay particular attention to
the overall design and direction of the project, ensure that
Maintainers and other contributors are familiar with that design, and
facilitate achieving consensus on difficult issues.
If the project is unable to achieve consensus on an issue, the Project
Lead may poll the Maintainers on the issue, and in the case of a tie,
the vote of the Project Lead will be the tie-breaker.
The Project Lead is elected to a term of one year. The election
process shall be a Condorcet election and the candidates shall be
self-nominated from among the existing Maintainers.
The Project Lead is James E. Blair (term expires 2024-01-16).
Zuul-Jobs Maintainers
---------------------
The zuul-jobs and zuul-base-jobs repositories contain a standard
library of reusable job components which are designed to be used in a
wide variety of situations.
Changes to these repositories require consideriation of the various
environments in which the jobs may be used as well as policies which
promote the consistency and stability of the components therein, but
not necessarily the full scope of Zuul development. To that end,
approval rights for changes to these repositories are granted to both
the Zuul Maintainers and an additional group known as the Zuul-Jobs
Maintainers. The reviewing processes are identical to the rest of the
project; membership changes to the Zuul-Jobs Maintainers group are
undertaken with consensus of the wider Zuul-Jobs group (not merely the
Zuul Maintainers).

:title: Operation
.. _operation:
Operation
=========
You can run any zuul process with the **-f** option to make it not
daemonize and stay in the foreground, logging to your terminal. It's a
good idea at first to check for issues with your configuration.
There's also a **-d** option to engage verbose debug logging, but be
careful in busy deployments as this can generate very large logs.
To start, simply run::
zuul-scheduler
Before Zuul can run any jobs, it needs to load its configuration, most
of which is in the git repositories that Zuul operates on. Start an
executor to allow zuul to do that::
zuul-executor
Zuul should now be able to read its configuration from the configured
repo and process any jobs defined therein.
Scheduler
---------
Operation
~~~~~~~~~
To start the scheduler, run ``zuul-scheduler``. To stop it, run
``zuul-scheduler stop``.
.. _reconfiguration:
Reconfiguration
~~~~~~~~~~~~~~~
Most of Zuul's configuration is automatically updated as changes to
the repositories which contain it are merged. However, Zuul must be
explicitly notified of changes to the tenant config file, since it is
not read from a git repository. Zuul supports two kinds of reconfigurations.
The full reconfiguration refetches and reloads the configuration of
all tenants. To do so, run ``zuul-scheduler full-reconfigure``. For
example this can be used to fix eventual configuration inconsistencies
after connection problems with the code hosting system.
To perform the same actions as a full reconfiguration but for a single
tenant, use ``zuul-scheduler tenant-reconfigure TENANT`` (where
``TENANT`` is the name of the tenant to reconfigure).
The smart reconfiguration reloads only the tenants that changed their
configuration in the tenant config file. To do so, run
``zuul-scheduler smart-reconfigure``. In multi tenant systems this can
be much faster than the full reconfiguration so it is recommended to
use the smart reconfiguration after changing the tenant configuration
file.
The ``tenant-reconfigure`` and ``smart-reconfigure`` commands should
only be run on a single scheduler. Other schedulers will see any
changes to the configuration stored in ZooKeeper and automatically
update their configuration in the background without interrupting
processing.
.. _backup:
Backup and Restoration
~~~~~~~~~~~~~~~~~~~~~~
While all of Zuul's component services are designed to be run in a
resilient active-active clustered deployment, a good disaster recovery
plan should include backing up critical data. At a minimum, the
randomly-generated project keys used for encryption of job secrets and
SSH access should be backed up, as they **cannot be recreated** if
lost. Zuul stores these keys in a keystore in ZooKeeper which is
inconvenient to back up directly, but provides an administrative tool
to :ref:`export <export-keys>` these keys to and :ref:`import
<import-keys>` them from a local directory.
It's highly recommended to set up periodic automation for dumping such
an export to a secure location (for example, on the filesystem of each
Zuul Scheduler) for use in a disaster where all ZooKeeper content is
lost. You may also consider configuring a safe remote backup of these
files with the tool of your choice, but be aware that they are
potentially sensitive since anyone who gains access to them could
decrypt job secrets or access protected systems which have been
instructed to trust those keys.
Note that the exported keys are symmetrically encrypted with the same
:ref:`keystore.password <keystore-password>` which is used for
encrypting and decrypting the copy of them in ZooKeeper, because its
the encrypted versions of the keys which are exported and imported.
Someone with access to the keys would also need a copy of the
keystore.password from Zuul's configuration, so for security-sensitive
environments you may not want to back them up together. Conversely, if
you lose the keystore.password then you also lose the use of the
project keys in the keystore and any exports, so you will likely want
to make sure you keep a secured copy of it somewhere as well in the
event your server configuration is lost.
Merger
------
Operation
~~~~~~~~~
To start the merger, run ``zuul-merger``.
In order to stop the merger and under normal circumstances it is
best to pause and wait for all currently running tasks to finish
before stopping it. To do so run ``zuul-merger pause``.
To stop the merger, run ``zuul-merger stop``. This will wait for any
currently running merge task to complete before exiting. As a result
this is always a graceful way to stop the merger.
``zuul-merger graceful`` is an alias for ``zuul-merger stop`` to make
this consistent with the executor.
Executor
--------
Operation
~~~~~~~~~
To start the executor, run ``zuul-executor``.
There are several commands which can be run to control the executor's
behavior once it is running.
To pause the executor and prevent it from running new jobs you can
run ``zuul-executor pause``.
To cause the executor to stop accepting new jobs and exit when all running
jobs have finished you can run ``zuul-executor graceful``. Under most
circumstances this will be the best way to stop Zuul.
To stop the executor immediately, run ``zuul-executor stop``. Jobs that were
running on the stopped executor will be rescheduled on other executors.
The executor normally responds to a ``SIGTERM`` signal in the same way
as the ``graceful`` command, however you can change this behavior to match
``stop`` with the :attr:`executor.sigterm_method` setting.
To enable or disable running Ansible in verbose mode (with the
``-vvv`` argument to ansible-playbook) run ``zuul-executor verbose``
and ``zuul-executor unverbose``.
.. _ansible-and-python-3:
Ansible and Python 3
~~~~~~~~~~~~~~~~~~~~
As noted above, the executor runs Ansible playbooks against the remote
node(s) allocated for the job. Since part of executing playbooks on
remote hosts is running Python scripts on them, Ansible needs to know
what Python interpreter to use on the remote host. With older
distributions, ``/usr/bin/python2`` was a generally sensible choice.
However, over time a heterogeneous Python ecosystem has evolved where
older distributions may only provide Python 2, most provide a mixed
2/3 environment and newer distributions may only provide Python 3 (and
then others like RHEL8 may even have separate "system" Python versions
to add to confusion!).
Ansible's ``ansible_python_interpreter`` variable configures the path
to the remote Python interpreter to use during playbook execution.
This value is set by Zuul from the ``python-path`` specified for the
node by Nodepool; see the `nodepool configuration documentation
<https://zuul-ci.org/docs/nodepool/configuration.html>`__.
This defaults to ``auto``, where Ansible will automatically discover
the interpreter available on the remote host. However, this setting
only became available in Ansible >=2.8, so Zuul will translate
``auto`` into the old default of ``/usr/bin/python2`` when configured
to use older Ansible versions.
Thus for modern Python 3-only hosts no further configuration is needed
when using Ansible >=2.8 (e.g. Fedora, Bionic onwards). If using
earlier Ansible versions you may need to explicitly set the
``python-path`` if ``/usr/bin/python2`` is not available on the node.
Ansible roles/modules which include Python code are generally Python 3
safe now, but there is still a small possibility of incompatibility.
See also the Ansible `Python 3 support page
<https://docs.ansible.com/ansible/latest/reference_appendices/python_3_support.html>`__.
.. _nodepool_console_streaming:
Log streaming
~~~~~~~~~~~~~
The log streaming service enables Zuul to show the live status of
long-running ``shell`` or ``command`` tasks. The server side is setup
by the ``zuul_console:`` task built-in to Zuul's Ansible installation.
The executor requires the ability to communicate with this server on
the job nodes via port ``19885`` for this to work.
The log streaming service spools command output via files on the job
node in the format ``/tmp/console-<uuid>-<task_id>-<host>.log``. By
default, it will clean these files up automatically.
Occasionally, a streaming file may be left if a job is interrupted.
These may be safely removed after a short period of inactivity with a
command such as
.. code-block:: shell
find /tmp -maxdepth 1 -name 'console-*-*-<host>.log' -mtime +2 -delete
If the executor is unable to reach port ``19885`` (for example due to
firewall rules), or the ``zuul_console`` daemon can not be run for
some other reason, the command to clean these spool files will not be
processed and they may be left behind; on an ephemeral node this is
not usually a problem, but on a static node these files will persist.
In this situation, Zuul can be instructed to not to create any spool
files for ``shell`` and ``command`` tasks via setting
``zuul_console_disabled: True`` (usually via a global host variable in
inventory). Live streaming of ``shell`` and ``command`` calls will of
course be unavailable in this case, but no spool files will be
created.
For Kubernetes-based job nodes the connection from the executor to the
``zuul_console`` daemon is established by using ``kubectl port-forward``
to forward a local port to the appropriate port on the pod containing
the job node. If the Kubernetes user is not bound to a role that has
authorization for port-forwarding, this will prevent connection to
the ``zuul_console`` daemon.
Web Server
----------
Operation
~~~~~~~~~
To start the web server, run ``zuul-web``. To stop it, kill the
PID which was saved in the pidfile specified in the configuration.
Finger Gateway
--------------
Operation
~~~~~~~~~
To start the finger gateway, run ``zuul-fingergw``. To stop it, kill the
PID which was saved in the pidfile specified in the configuration.

:title: Zuul Concepts
Zuul Concepts
=============
Zuul is organized around the concept of a *pipeline*. In Zuul, a
pipeline encompasses a workflow process which can be applied to one or
more projects. For instance, a "check" pipeline might describe the
actions which should cause newly proposed changes to projects to be
tested. A "gate" pipeline might implement :ref:`project_gating` to
automate merging changes to projects only if their tests pass. A
"post" pipeline might update published documentation for a project
when changes land.
The names "check", "gate", and "post" are arbitrary -- these are not
concepts built into Zuul, but rather they are just a few common
examples of workflow processes that can be described to Zuul and
implemented as pipelines.
Once a pipeline has been defined, any number of projects may be
associated with it, each one specifying what jobs should be run for
that project in a given pipeline.
Pipelines have associated *triggers* which are descriptions of events
which should cause something to be enqueued into a pipeline. For
example, when a patchset is uploaded to Gerrit, a Gerrit
*patchset-created* event is emitted. A pipeline configured to trigger
on *patchset-created* events would then enqueue the associated change
when Zuul receives that event. If there are jobs associated with that
project and pipeline, they will be run. In addition to Gerrit, other
triggers are available, including GitHub, timer, and zuul. See
:ref:`drivers` for a full list of available triggers.
Once all of the jobs for an item in a pipeline have been run, the
pipeline's *reporters* are responsible for reporting the results of
all of the jobs. Continuing the example from earlier, if a pipeline
were configured with a Gerrit reporter, it would leave a review
comment on the change and set any approval votes that are configured.
There are several reporting phases available; each of which may be
configured with any number of reporters. See :ref:`drivers` for a
full list of available reporters.
The items enqueued into a pipeline are each associated with a
`git ref <https://git-scm.com/book/en/v2/Git-Internals-Git-References>`_.
That ref may point to a proposed change, or it may be the tip of a
branch or a tag. The triggering event determines the ref, and whether
it represents a proposed or merged commit. Zuul prepares the ref for
an item before running jobs. In the case of a proposed change, that
means speculatively merging the change into its target branch. This
means that any jobs that operate on the change will run with the git
repo in the state it will be in after the change merges (which may be
substantially different than the git repo state of the change itself
since the repo may have merged other changes since the change was
originally authored). Items in a pipeline may depend on other items,
and if they do, all of their dependent changes will be included in the
git repo state that Zuul prepares. Jobs may also specify that they
require additional git repos, and if so, the repo state (as of the
time when the item was enqueued in the pipeline) for those repos will
also be included. For more detail on this process, see
:ref:`project_gating`, :ref:`dependencies`, and
:ref:`global_repo_state`.
The configuration for nearly everything described above is held in
files inside of the git repos upon which Zuul operates. Zuul's
configuration is global, but distributed. Jobs which are defined in
one project might be used in another project while pipelines are
available to all projects. When Zuul starts, it reads its
configuration from all of the projects it knows about, and when
changes to its configuration are proposed, those changes may take
effect temporarily as part of the proposed change, or immediately
after the change merges, depending on the type of project in which the
change appears.
Jobs specify the type and quantity of nodes which they require.
Before executing each job, Zuul will contact its companion program,
Nodepool, to supply them. Nodepool may be configured to supply static
nodes or contact cloud providers to create or delete nodes as
necessary. The types of nodes available to Zuul are determined by the
Nodepool administrator.
The executable contents of jobs themselves are Ansible playbooks.
Ansible's support for orchestrating tasks on remote nodes is
particularly suited to Zuul's support for multi-node testing. Ansible
is also easy to use for simple tasks (such as executing a shell
script) or sophisticated deployment scenarios. When Zuul runs
Ansible, it attempts to do so in a manner most similar to the way that
Ansible might be used to orchestrate remote systems. Ansible itself
is run on the :ref:`executor <executor>` and acts remotely upon the test
nodes supplied to a job. This facilitates continuous delivery by making it
possible to use the same Ansible playbooks in testing and production.

:title: Job Content
.. _job-content:
Job Content
===========
Zuul jobs are implemented as Ansible playbooks. Zuul prepares the
repositories used for a job, installs any required Ansible roles, and
then executes the job's playbooks. Any setup or artifact collection
required is the responsibility of the job itself. While this flexible
arrangement allows for almost any kind of job to be run by Zuul,
batteries are included. Zuul has a standard library of jobs upon
which to build.
Working Directory
-----------------
Before starting each job, the Zuul executor creates a directory to
hold all of the content related to the job. This includes some
directories which are used by Zuul to configure and run Ansible and
may not be accessible, as well as a directory tree, under ``work/``,
that is readable and writable by the job. The hierarchy is:
**work/**
The working directory of the job.
**work/src/**
Contains the prepared git repositories for the job.
**work/logs/**
Where the Ansible log for the job is written; your job
may place other logs here as well.
Git Repositories
----------------
The git repositories in ``work/src`` contain the repositories for all
of the projects specified in the ``required-projects`` section of the
job, plus the project associated with the queue item if it isn't
already in that list. In the case of a proposed change, that change
and all of the changes ahead of it in the pipeline queue will already
be merged into their respective repositories and target branches. The
change's project will have the change's branch checked out, as will
all of the other projects, if that branch exists (otherwise, a
fallback or default branch will be used). If your job needs to
operate on multiple branches, simply checkout the appropriate branches
of these git repos to ensure that the job results reflect the proposed
future state that Zuul is testing, and all dependencies are present.
The git repositories will have a remote ``origin`` with refs pointing
to the previous change in the speculative state. This means that e.g.
a ``git diff origin/<branch>..<branch>`` will show the changes being
tested. Note that the ``origin`` URL is set to a bogus value
(``file:///dev/null``) and can not be used for updating the repository
state; the local repositories are guaranteed to be up to date.
The repositories will be placed on the filesystem in directories
corresponding with the canonical hostname of their source connection.
For example::
work/src/git.example.com/project1
work/src/github.com/project2
Is the layout that would be present for a job which included project1
from the connection associated to git.example.com and project2 from
GitHub. This helps avoid collisions between projects with the same
name, and some language environments, such as Go, expect repositories
in this format.
Note that these git repositories are located on the executor; in order
to be useful to most kinds of jobs, they will need to be present on
the test nodes. The ``base`` job in the standard library (see
`zuul-base-jobs documentation`_ for details) contains a
pre-playbook which copies the repositories to all of the job's nodes.
It is recommended to always inherit from this base job to ensure that
behavior.
.. _zuul-base-jobs documentation: https://zuul-ci.org/docs/zuul-base-jobs/jobs.html#job-base
.. TODO: document src (and logs?) directory
.. _user_jobs_variable_inheritance:
Variables
---------
There are several sources of variables which are available to Ansible:
variables defined in jobs, secrets, and site-wide variables. The
order of precedence is:
#. :ref:`Site-wide variables <user_jobs_sitewide_variables>`
#. :ref:`Job extra variables <user_jobs_job_extra_variables>`
#. :ref:`Secrets <user_jobs_secrets>`
#. :ref:`Job variables <user_jobs_job_variables>`
#. :ref:`Project variables <user_jobs_project_variables>`
#. :ref:`Parent job results <user_jobs_parent_results>`
Meaning that a site-wide variable with the same name as any other will
override its value, and similarly, secrets override job variables of
the same name which override data returned from parent jobs. Each of
the sources is described below.
.. _user_jobs_sitewide_variables:
Site-wide Variables
~~~~~~~~~~~~~~~~~~~
The Zuul administrator may define variables which will be available to
all jobs running in the system. These are statically defined and may
not be altered by jobs. See the :ref:`Administrator's Guide
<admin_sitewide_variables>` for information on how a site
administrator may define these variables.
.. _user_jobs_job_extra_variables:
Job Extra Variables
~~~~~~~~~~~~~~~~~~~
Any extra variables in the job definition (using the :attr:`job.extra-vars`
attribute) are available to Ansible but not added into the inventory file.
.. _user_jobs_secrets:
Secrets
~~~~~~~
:ref:`Secrets <secret>` also appear as variables available to Ansible.
Unlike job variables, these are not added to the inventory file (so
that the inventory file may be kept for debugging purposes without
revealing secrets). But they are still available to Ansible as normal
variables. Because secrets are groups of variables, they will appear
as a dictionary structure in templates, with the dictionary itself
being the name of the secret, and its members the individual items in
the secret. For example, a secret defined as:
.. code-block:: yaml
- secret:
name: credentials
data:
username: foo
password: bar
Might be used in a template as::
{{ credentials.username }} {{ credentials.password }}
Secrets are only available to playbooks associated with the job
definition which uses the secret; they are not available to playbooks
associated with child jobs or job variants.
.. _user_jobs_job_variables:
Job Variables
~~~~~~~~~~~~~
Any variables specified in the job definition (using the
:attr:`job.vars` attribute) are available as Ansible host variables.
They are added to the ``vars`` section of the inventory file under the
``all`` hosts group, so they are available to all hosts. Simply refer
to them by the name specified in the job's ``vars`` section.
.. _user_jobs_project_variables:
Project Variables
~~~~~~~~~~~~~~~~~
Any variables specified in the project definition (using the
:attr:`project.vars` attribute) are available to jobs as Ansible host
variables in the same way as :ref:`job variables
<user_jobs_job_variables>`. Variables set in a ``project-template``
are merged into the project variables when the template is included by
a project.

~~~~~~~~~~~~~~~~~~
A job may return data to Zuul for later use by jobs which depend on
it. For details, see :ref:`return_values`.
Zuul Variables
--------------
Zuul supplies not only the variables specified by the job definition
to Ansible, but also some variables from Zuul itself.
When a pipeline is triggered by an action, it enqueues items which may
vary based on the pipeline's configuration. For example, when a new
change is created, that change may be enqueued into the pipeline,
while a tag may be enqueued into the pipeline when it is pushed.
Information about these items is available to jobs. All of the items
enqueued in a pipeline are git references, and therefore share some
attributes in common. But other attributes may vary based on the type
of item.
.. var:: zuul
All items provide the following information as Ansible variables
under the ``zuul`` key:
.. var:: artifacts
:type: list
If the job has a :attr:`job.requires` attribute, and Zuul has
found changes ahead of this change in the pipeline with matching
:attr:`job.provides` attributes, then information about any
:ref:`artifacts returned <return_artifacts>` from those jobs
will appear here.
This value is a list of dictionaries with the following format:
.. var:: project
The name of the project which supplied this artifact.
.. var:: change
The change number which supplied this artifact.
.. var:: patchset
The patchset of the change.
.. var:: job
The name of the job which produced the artifact.
.. var:: name
The name of the artifact (as supplied to :ref:`return_artifacts`).
.. var:: url
The URL of the artifact (as supplied to :ref:`return_artifacts`).
.. var:: metadata
The metadata of the artifact (as supplied to :ref:`return_artifacts`).
.. var:: build
The UUID of the build. A build is a single execution of a job.
When an item is enqueued into a pipeline, this usually results
in one build of each job configured for that item's project.
However, items may be re-enqueued in which case another build
may run. In dependent pipelines, the same job may run multiple
times for the same item as circumstances change ahead in the
queue. Each time a job is run, for whatever reason, it is
acompanied with a new unique id.
.. var:: buildset
The build set UUID. When Zuul runs jobs for an item, the
collection of those jobs is known as a buildset. If the
configuration of items ahead in a dependent pipeline changes,
Zuul creates a new buildset and restarts all of the jobs.
.. var:: child_jobs
A list of the first level dependent jobs to be run after this job
has finished successfully.
.. var:: ref
The git ref of the item. This will be the full path (e.g.,
`refs/heads/master` or `refs/changes/...`).
.. var:: override_checkout
If the job was configured to override the branch or tag checked
out, this will contain the specified value. Otherwise, this
variable will be undefined.
.. var:: pipeline
The name of the pipeline in which the job is being run.
.. var:: post_review
:type: bool
Whether the current job is running in a post-review pipeline or not.
.. var:: job
The name of the job being run.
.. var:: event_id
The UUID of the event that triggered this execution. This is mainly
useful for debugging purposes.
.. var:: voting
A boolean indicating whether the job is voting.
.. var:: attempts
An integer count of how many attempts have been made to run this
job for the current buildset. If there are pre-run failures or network
connectivity issues then previous attempts may have been cancelled,
and this value will be greater than 1.
.. var:: max_attempts
The number of attempts that will be be made for this job when
encountering an error in a pre-playbook before it is reported as failed.
This value is taken from :attr:`job.attempts`.
.. var:: ansible_version
The version of the Ansible community package release used for executing
the job.
.. var:: project
The item's project. This is a data structure with the following
fields:
.. var:: name
The name of the project, excluding hostname. E.g., `org/project`.
.. var:: short_name
The name of the project, excluding directories or
organizations. E.g., `project`.
.. var:: canonical_hostname
The canonical hostname where the project lives. E.g.,
`git.example.com`.
.. var:: canonical_name
The full canonical name of the project including hostname.
E.g., `git.example.com/org/project`.
.. var:: src_dir
The path to the source code relative to the work dir. E.g.,
`src/git.example.com/org/project`.
.. var:: projects
:type: dict
A dictionary of all projects prepared by Zuul for the item. It
includes, at least, the item's own project. It also includes
the projects of any items this item depends on, as well as the
projects that appear in :attr:`job.required-projects`.
This is a dictionary of dictionaries. Each value has a key of
the `canonical_name`, then each entry consists of:
.. var:: name
The name of the project, excluding hostname. E.g., `org/project`.
.. var:: short_name
The name of the project, excluding directories or
organizations. E.g., `project`.
.. var:: canonical_hostname
The canonical hostname where the project lives. E.g.,
`git.example.com`.
.. var:: canonical_name
The full canonical name of the project including hostname.
E.g., `git.example.com/org/project`.
.. var:: src_dir
The path to the source code, relative to the work dir. E.g.,
`src/git.example.com/org/project`.
.. var:: required
A boolean indicating whether this project appears in the
:attr:`job.required-projects` list for this job.
.. var:: checkout
The branch or tag that Zuul checked out for this project.
This may be influenced by the branch or tag associated with
the item as well as the job configuration.
.. var:: checkout_description
A human-readable description of why Zuul chose this
particular branch or tag to be checked out. This is intended
as a debugging aid in the case of complex jobs. The specific
text is not defined and is subject to change.
.. var:: commit
The hex SHA of the commit checked out. This commit may
appear in the upstream repository, or if it the result of a
speculative merge, it may only exist during the run of this
job.
For example, to access the source directory of a single known
project, you might use::
{{ zuul.projects['git.example.com/org/project'].src_dir }}
To iterate over the project list, you might write a task
something like::
- name: Sample project iteration
debug:
msg: "Project {{ item.name }} is at {{ item.src_dir }}
with_items: {{ zuul.projects.values() | list }}
.. var:: playbook_context
:type: dict
This dictionary contains information about the execution of each
playbook in the job. This may be useful for understanding
exactly what playbooks and roles Zuul executed.
All paths herein are located under the root of the build
directory (note that is one level higher than the workspace
directory accessible to jobs on the executor).
.. var:: playbook_projects
:type: dict
A dictionary of projects that have been checked out for
playbook execution. When used in the trusted execution
context, these will contain only merged commits in upstream
repositories. In the case of the untrusted context, they may
contain speculatively merged code.
The key is the path and each value is another dictionary with
the following keys:
.. var:: canonical_name
The canonical name of the repository.
.. var:: checkout
The branch or tag checked out.
.. var:: commit
The hex SHA of the commit checked out. As above, this
commit may or may not exist in the upstream repository
depending on whether it was the result of a speculative
merge.
.. var:: playbooks
:type: list
An ordered list of playbooks executed for the job. Each item
is a dictionary with the following keys:
.. var:: path
The path to the playbook.
.. var:: roles
:type: list
Information about the roles available to the playbook.
The actual `role path` supplied to Ansible is the
concatenation of the ``role_path`` entry in each of the
following dictionaries. The rest of the information
describes what is in the role path.
In order to deal with the many possible role layouts and
aliases, each element in the role path gets its own
directory. Depending on the contents and alias
configuration for that role repo, a symlink is added to
one of the repo checkouts in
:var:`zuul.playbook_context.playbook_projects` so that the
role may be supplied to Ansible with the correct name.
.. var:: checkout
The branch or tag checked out.
.. var:: checkout_description
A human-readable description of why Zuul chose this
particular branch or tag to be checked out. This is
intended as a debugging aid in the case of complex
jobs. The specific text is not defined and is subject
to change.
.. var:: link_name
The name of the symbolic link.
.. var:: link_target
The target of the symbolic_link.
.. var:: role_path
The role path passed to Ansible.
.. var:: tenant
The name of the current Zuul tenant.
.. var:: timeout
The job timeout, in seconds.
.. var:: post_timeout
The post-run playbook timeout, in seconds.
.. var:: jobtags
A list of tags associated with the job. Not to be confused with
git tags, these are simply free-form text fields that can be
used by the job for reporting or classification purposes.
.. var:: items
:type: list
.. note::
``zuul.items`` conflicts with the ``items()`` builtin so the
variable can only be accessed with python dictionary like syntax,
e.g: ``zuul['items']``
A list of dictionaries, each representing an item being tested
with this change with the format:
.. var:: project
The item's project. This is a data structure with the
following fields:
.. var:: name
The name of the project, excluding hostname. E.g.,
`org/project`.
.. var:: short_name
The name of the project, excluding directories or
organizations. E.g., `project`.
.. var:: canonical_hostname
The canonical hostname where the project lives. E.g.,
`git.example.com`.
.. var:: canonical_name
The full canonical name of the project including hostname.
E.g., `git.example.com/org/project`.
.. var:: src_dir
The path to the source code on the remote host, relative
to the home dir of the remote user.
E.g., `src/git.example.com/org/project`.
.. var:: branch
The target branch of the change (without the `refs/heads/` prefix).
.. var:: bundle_id
The id of the bundle if the change is in a circular dependency cycle.
.. var:: change
The identifier for the change.
.. var:: change_url
The URL to the source location of the given change.
E.g., `https://review.example.org/#/c/123456/` or
`https://github.com/example/example/pull/1234`.
.. var:: patchset
The patchset identifier for the change. If a change is
revised, this will have a different value.
.. var:: resources
:type: dict
A job using a container build resources has access to a resources variable
that describes the resource. Resources is a dictionary of group keys,
each value consists of:
.. var:: namespace
The resource's namespace name.
.. var:: context
The kube config context name.
.. var:: pod
The name of the pod when the label defines a kubectl connection.
Project or namespace resources might be used in a template as:
.. code-block:: yaml
- hosts: localhost
tasks:
- name: Create a k8s resource
k8s_raw:
state: present
context: "{{ zuul.resources['node-name'].context }}"
namespace: "{{ zuul.resources['node-name'].namespace }}"
Kubectl resources might be used in a template as:
.. code-block:: yaml
- hosts: localhost
tasks:
- name: Copy src repos to the pod
command: >
oc rsync -q --progress=false
{{ zuul.executor.src_root }}/
{{ zuul.resources['node-name'].pod }}:src/
no_log: true
.. var:: zuul_success
Post run playbook(s) will be passed this variable to indicate if the run
phase of the job was successful or not. This variable is meant to be used
with the `bool` filter.
.. code-block:: yaml
tasks:
- shell: echo example
when: zuul_success | bool
.. var:: zuul_will_retry
Post run and cleanup playbook(s) will be passed this variable to indicate
if the job will be retried. This variable is meant to be used with the
`bool` filter.
.. code-block:: yaml
tasks:
- shell: echo example
when: zuul_will_retry | bool
.. var:: nodepool
Information about each host from Nodepool is supplied in the
`nodepool` host variable. Availability of values varies based on
the node and the driver that supplied it. Values may be ``null``
if they are not applicable.
.. var:: label
The nodepool label of this node.
.. var:: az
The availability zone in which this node was placed.
.. var:: cloud
The name of the cloud in which this node was created.
.. var:: provider
The name of the nodepool provider of this node.
.. var:: region
The name of the nodepool provider's region.
.. var:: host_id
The cloud's host identification for this node's hypervisor.
.. var:: external_id
The cloud's identifier for this node.
.. var:: slot
If the node supports running multiple jobs on the node, a unique
numeric ID for the subdivision of the node assigned to this job.
This may be used to avoid build directory collisions.
.. var:: interface_ip
The best IP address to use to contact the node as determined by
the cloud provider and nodepool.
.. var:: public_ipv4
A public IPv4 address of the node.
.. var:: private_ipv4
A private IPv4 address of the node.
.. var:: public_ipv6
A public IPv6 address of the node.
.. var:: private_ipv6
A private IPv6 address of the node.
Change Items
~~~~~~~~~~~~
A change to the repository. Most often, this will be a git reference
which has not yet been merged into the repository (e.g., a gerrit
change or a GitHub pull request). The following additional variables
are available:
.. var:: zuul
:hidden:
.. var:: branch
The target branch of the change (without the `refs/heads/` prefix).
.. var:: change
The identifier for the change.
.. var:: patchset
The patchset identifier for the change. If a change is revised,
this will have a different value.
.. var:: change_url
The URL to the source location of the given change.
E.g., `https://review.example.org/#/c/123456/` or
`https://github.com/example/example/pull/1234`.
.. var:: message
The commit or pull request message of the change base64 encoded. Use the
`b64decode` filter in ansible when working with it.
.. warning:: This variable is deprecated and will be removed in
a future version. Use :var:`zuul.change_message`
instead.
.. var:: change_message
The commit or pull request message of the change. When Zuul
runs Ansible, this variable is tagged with the ``!unsafe`` YAML
tag so that Ansible will not interpolate values into it. Note,
however, that the `inventory.yaml` file placed in the build's
workspace for debugging and inspection purposes does not inclued
the ``!unsafe`` tag.
.. var:: commit_id
The git sha of the change. This may be the commit sha of the
current patchset revision or the tip of a pull request branch
depending on the source. Because of Zuul's speculative merge
process, this commit may not even appear in the prepared git
repos, so it should not be relied upon for git operations in
jobs. It is included here to support interfacing with systems
that identify a change by the commit.
Branch Items
~~~~~~~~~~~~
This represents a branch tip. This item may have been enqueued
because the branch was updated (via a change having merged, or a
direct push). Or it may have been enqueued by a timer for the purpose
of verifying the current condition of the branch. The following
additional variables are available:
.. var:: zuul
:hidden:
.. var:: branch
The name of the item's branch (without the `refs/heads/`
prefix).
.. var:: oldrev
If the item was enqueued as the result of a change merging or
being pushed to the branch, the git sha of the old revision will
be included here. Otherwise, this variable will be undefined.
.. var:: newrev
If the item was enqueued as the result of a change merging or
being pushed to the branch, the git sha of the new revision will
be included here. Otherwise, this variable will be undefined.
.. var:: commit_id
The git sha of the branch. Identical to ``newrev`` or
``oldrev`` if defined.
Tag Items
~~~~~~~~~
This represents a git tag. The item may have been enqueued because a
tag was created or deleted. The following additional variables are
available:
.. var:: zuul
:hidden:
.. var:: tag
The name of the item's tag (without the `refs/tags/` prefix).
.. var:: oldrev
If the item was enqueued as the result of a tag being deleted,
the previous git sha of the tag will be included here. If the
tag was created, this variable will be undefined.
.. var:: newrev
If the item was enqueued as the result of a tag being created,
the new git sha of the tag will be included here. If the tag
was deleted, this variable will be undefined.
.. var:: commit_id
The git sha of the branch. Identical to ``newrev`` or
``oldrev`` if defined.
Ref Items
~~~~~~~~~
This represents a git reference that is neither a change, branch, or
tag. Note that all items include a `ref` attribute which may be used
to identify the ref. The following additional variables are
available:
.. var:: zuul
:hidden:
.. var:: oldrev
If the item was enqueued as the result of a ref being deleted,
the previous git sha of the ref will be included here. If the
ref was created, this variable will be undefined.
.. var:: newrev
If the item was enqueued as the result of a ref being created,
the new git sha of the ref will be included here. If the ref
was deleted, this variable will be undefined.
.. var:: commit_id
The git sha of the branch. Identical to ``newrev`` or
``oldrev`` if defined.
Working Directory
~~~~~~~~~~~~~~~~~
Additionally, some information about the working directory and the
executor running the job is available:
.. var:: zuul
:hidden:
.. var:: executor
A number of values related to the executor running the job are
available:
.. var:: hostname
The hostname of the executor.
.. var:: src_root
The path to the source directory.
.. var:: log_root
The path to the logs directory.
.. var:: work_root
The path to the working directory.
.. var:: inventory_file
The path to the inventory. This variable is needed for jobs running
without a nodeset since Ansible doesn't set it for localhost; see
this `porting guide
<https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.4.html#inventory>`_.
The inventory file is only readable by jobs running in a
:term:`trusted execution context`.
SSH Keys
--------
Zuul starts each job with an SSH agent running and at least one key
added to that agent. Generally you won't need to be aware of this
since Ansible will use this when performing any tasks on remote nodes.
However, under some circumstances you may want to interact with the
agent. For example, you may wish to add a key provided as a secret to
the job in order to access a specific host, or you may want to, in a
pre-playbook, replace the key used to log into the assigned nodes in
order to further protect it from being abused by untrusted job
content.
A description of each of the keys added to the SSH agent follows.
Nodepool Key
~~~~~~~~~~~~
This key is supplied by the system administrator. It is expected to
be accepted by every node supplied by Nodepool and is generally the
key that will be used by Zuul when running jobs. Because of the
potential for an unrelated job to add an arbitrary host to the Ansible
inventory which might accept this key (e.g., a node for another job,
or a static host), the use of the `add-build-sshkey
<https://zuul-ci.org/docs/zuul-jobs/general-roles.html#role-add-build-sshkey>`_
role is recommended.
Project Key
~~~~~~~~~~~
Each project in Zuul has its own SSH keypair. This key is added to
the SSH agent for all jobs running in a post-review pipeline. If a
system administrator trusts that project, they can add the project's
public key to systems to allow post-review jobs to access those
systems. The systems may be added to the inventory using the
``add_host`` Ansible module, or they may be supplied by static nodes
in Nodepool.
Zuul serves each project's public SSH key using its build-in
webserver. They can be fetched at the path
``/api/tenant/<tenant>/project-ssh-key/<project>.pub`` where
``<project>`` is the canonical name of a project and ``<tenant>`` is
the name of a tenant with that project.
.. _return_values:
Return Values
-------------
A job may return some values to Zuul to affect its behavior and for
use by dependent jobs. To return a value, use the ``zuul_return``
Ansible module in a job playbook.
For example:
.. code-block:: yaml
tasks:
- zuul_return:
data:
foo: bar
Will return the dictionary ``{'foo': 'bar'}`` to Zuul.
Optionally, if you have a large supply of data to return, you may specify the
path to a JSON-formatted file with that data. For example:
.. code-block:: yaml
tasks:
- zuul_return:
file: /path/to/data.json
Normally returned data are provided to dependent jobs in the inventory
file, which may end up in the log archive of a job. In the case where
sensitive data must be provided to dependent jobs, the ``secret_data``
attribute may be used instead, and the data will be provided via the
same mechanism as job secrets, where the data are not written to disk
in the work directory. Care must still be taken to avoid displaying
or storing sensitive data within the job. For example:
.. code-block:: yaml
tasks:
- zuul_return:
secret_data:
password: foobar
.. TODO: xref to section describing formatting
Any values other than those in the ``zuul`` hierarchy will be supplied
as Ansible variables to dependent jobs. These variables have less
precedence than any other type of variable in Zuul, so be sure their
names are not shared by any job variables. If more than one parent
job returns the same variable, the value from the later job in the job
graph will take precedence.
The values in the ``zuul`` hierarchy are special variables that influence the
behavior of zuul itself. The following paragraphs describe the currently
supported special variables and their meaning.
Returning the log url
~~~~~~~~~~~~~~~~~~~~~
To set the log URL for a build, use *zuul_return* to set the
**zuul.log_url** value. For example:
.. code-block:: yaml
tasks:
- zuul_return:
data:
zuul:
log_url: http://logs.example.com/path/to/build/logs
.. _return_artifacts:
Returning artifact URLs
~~~~~~~~~~~~~~~~~~~~~~~
If a build produces artifacts, any number of URLs may be returned to
Zuul and stored in the SQL database. These will then be available via
the web interface and subsequent jobs.
To provide artifact URLs for a build, use *zuul_return* to set keys
under the :var:`zuul.artifacts` dictionary. For example:
.. code-block:: yaml
tasks:
- zuul_return:
data:
zuul:
artifacts:
- name: tarball
url: http://example.com/path/to/package.tar.gz
metadata:
version: 3.0
- name: docs
url: build/docs/
If the value of **url** is a relative URL, it will be combined with
the **zuul.log_url** value if set to create an absolute URL. The
**metadata** key is optional; if it is provided, it must be a
dictionary; its keys and values may be anything.
If *zuul_return* is invoked multiple times (e.g., via multiple
playbooks), then the elements of :var:`zuul.artifacts` from each
invocation will be appended.
.. _skipping child jobs:
Skipping dependent jobs
~~~~~~~~~~~~~~~~~~~~~~~
.. note::
In the following section the use of 'child jobs' refers to dependent jobs
configured by `job.dependencies` and should not be confused with jobs
that inherit from a parent job.
To skip a dependent job for the current build, use *zuul_return* to set the
:var:`zuul.child_jobs` value. For example:
.. code-block:: yaml
tasks:
- zuul_return:
data:
zuul:
child_jobs:
- dependent_jobA
- dependent_jobC
Will tell zuul to only run the dependent_jobA and dependent_jobC for pre-configured
dependent jobs. If dependent_jobB was configured, it would be now marked as SKIPPED. If
zuul.child_jobs is empty, all jobs will be marked as SKIPPED. Invalid dependent jobs
are stripped and ignored, if only invalid jobs are listed it is the same as
providing an empty list to zuul.child_jobs.
Leaving warnings
~~~~~~~~~~~~~~~~
A job can leave warnings that will be appended to the comment zuul leaves on
the change. Use *zuul_return* to add a list of warnings. For example:
.. code-block:: yaml
tasks:
- zuul_return:
data:
zuul:
warnings:
- This warning will be posted on the change.
If *zuul_return* is invoked multiple times (e.g., via multiple
playbooks), then the elements of **zuul.warnings** from each
invocation will be appended.
Leaving file comments
~~~~~~~~~~~~~~~~~~~~~
To instruct the reporters to leave line comments on files in the
change, set the **zuul.file_comments** value. For example:
.. code-block:: yaml
tasks:
- zuul_return:
data:
zuul:
file_comments:
path/to/file.py:
- line: 42
message: "Line too long"
level: info
- line: 82
message: "Line too short"
- line: 119
message: "This block is indented too far."
level: warning
range:
start_line: 117
start_character: 0
end_line: 119
end_character: 37
Not all reporters currently support line comments (or all of the
features of line comments); in these cases, reporters will simply
ignore this data. The ``level`` is optional, but if provided must
be one of ``info``, ``warning``, ``error``.
Zuul will attempt to automatically translate the supplied line numbers
to the corresponding lines in the original change as written (they may
differ due to other changes which may have merged since the change was
written). If this produces erroneous results for a job, the behavior
may be disabled by setting the
**zuul.disable_file_comment_line_mapping** variable to ``true`` in
*zuul_return*.
If *zuul_return* is invoked multiple times (e.g., via multiple playbooks), then
the elements of `zuul.file_comments` from each invocation will be appended.
Pausing the job
~~~~~~~~~~~~~~~
A job can be paused after the run phase by notifing zuul during the run phase.
In this case the dependent jobs can start and the prior job stays paused until
all dependent jobs are finished. This for example can be useful to start
a docker registry in a job that will be used by the dependent job.
To indicate that the job should be paused use *zuul_return* to
set the **zuul.pause** value.
You still can at the same time supply any arbitrary data to the dependent jobs.
For example:
.. code-block:: yaml
tasks:
- zuul_return:
data:
zuul:
pause: true
registry_ip_address: "{{ hostvars[groups.all[0]].ansible_host }}"
Skipping retries
~~~~~~~~~~~~~~~~
It's possible to skip the retry caused by a failure in ``pre-run``
by setting **zuul.retry** to ``false``.
For example the following would skip retrying the build:
.. code-block:: yaml
tasks:
- zuul_return:
data:
zuul:
retry: false
.. _build_status:
Build Status
------------
A job build may have the following status:
**SUCCESS**
Nominal job execution.
**FAILURE**
Job executed correctly, but exited with a failure.
**RETRY**
The ``pre-run`` playbook failed and the job will be retried.
**RETRY_LIMIT**
The ``pre-run`` playbook failed more than the maximum number of
retry ``attempts``.
**POST_FAILURE**
The ``post-run`` playbook failed.
**SKIPPED**
One of the build dependencies failed and this job was not executed.
**NODE_FAILURE**
The test instance provider was unable to fullfill the nodeset request.
This can happen if Nodepool is unable to provide the requested node(s)
for the request.

About Zuul
==========
Zuul is a Project Gating System. That's like a CI or CD system, but
the focus is on testing the future state of code repositories.
A gating system doesn't just test a proposed change; it tests the
proposed future state of multiple branches and repositories with any
number of in-flight changes and their dependencies. And the same
playbooks used to test software can also be used to deploy it.
Zuul itself is a service which listens to events from various code
review systems, executes jobs based on those events, and reports the
results back to the code review system. The primary interface for
Zuul is the code review system (or systems) so that it fits seamlessly
into developer workflows, and a web interface is available for
inspecting the current status and browsing build results.
The best way to run Zuul is with a single installation serving as many
projects or groups as possible. It is a multi-tenant application that
is able to provide as much or as little separation between projects as
desired.
Zuul works with a wide range of code review systems, and can work with
multiple systems (including integrating projects on different systems)
simultaneously. See :ref:`drivers` for a complete list.
Zuul uses a separate component called `Nodepool`_ to provide the
resources to run jobs. Nodepool works with several cloud providers
as well as statically defined nodes (again, simultaneously).
Because Zuul is designed from the ground up to run jobs in a
multi-node environment (whether those nodes are bare metal machines,
VMs, Kubernetes clusters, or containers), Zuul's job definition
language needs to support orchestrating tasks on multiple nodes. Zuul
uses Ansible for this. Ansible is well-known and easy to learn and
use. Some existing Ansible playbooks and roles may be able to be used
directly with Zuul (but some restrictions apply, so not all will).
However, knowledge or use of Ansible is not required for Zuul -- it is
quite simple for Zuul's embedded Ansible to run any shell script or
any other program. Zuul's library of standard jobs even includes a
job that will run a specified shell script, so it's possible to use
Zuul without writing any Ansible at all.
Zuul is an open source project developed and maintained by a community
of users. We welcome your `support and contribution
<https://zuul-ci.org/community.html>`__.

:title: Tracing
.. _tracing:
Tracing
=======
Zuul includes support for `distributed tracing`_ as described by the
OpenTelemetry project. This allows operators (and potentially users)
to visualize the progress of events and queue items through the
various Zuul components as an aid to debugging.
OpenTelemetry defines several observability signals such as traces,
metrics, and logs. Zuul uses other systems for metrics and logs; only
traces are exported via OpenTelemetry.
Zuul supports the OpenTelemetry Protocol (OTLP) for exporting traces.
Many observability systems support receiving traces via OTLP
(including Jaeger tracing).
Configuration
-------------
Related configuration is in the :attr:`tracing` section of ``zuul.conf``.
Tutorial

:title: Configuration
Configuration
=============
All Zuul processes read the ``/etc/zuul/zuul.conf`` file (an alternate
location may be supplied on the command line) which uses an INI file
syntax. Each component may have its own configuration file, though
you may find it simpler to use the same file for all components.
Zuul will interpolate environment variables starting with the
``ZUUL_`` prefix given in the config file escaped as python string
expansion. ``foo=%(ZUUL_HOME)s`` will set the value of ``foo`` to the
same value as the environment variable named ``ZUUL_HOME``.
An example ``zuul.conf``:
.. code-block:: ini
[zookeeper]
hosts=zk1.example.com,zk2.example.com,zk3.example.com
[database]
dburi=<URI>
[keystore]
password=MY_SECRET_PASSWORD
[web]
status_url=https://zuul.example.com/status
[scheduler]
log_config=/etc/zuul/scheduler-logging.yaml
Common Options
--------------
The following sections of ``zuul.conf`` are used by all Zuul components:
Statsd
~~~~~~
.. attr:: statsd
Information about the optional statsd server. If the ``statsd``
python module is installed and this section is configured,
statistics will be reported to statsd. See :ref:`statsd` for more
information.
.. attr:: server
Hostname or IP address of the statsd server.
.. attr:: port
:default: 8125
The UDP port on which the statsd server is listening.
.. attr:: prefix
If present, this will be prefixed to all of the keys before
transmitting to the statsd server.
Tracing
~~~~~~~
.. attr:: tracing
Information about the optional OpenTelemetry tracing configuration.
See :ref:`tracing` for more information.
.. attr:: enabled
:required:
To enable tracing, set this value to ``true``. This is the only
required parameter in order to export to a collector running
locally.
.. attr:: protocol
:default: grpc
The OTLP wire protocol to use.
.. value:: grpc
Use gRPC (the default).
.. value:: http/protobuf
Use HTTP with protobuf encoding.
.. attr:: endpoint
The endpoint to use. The default is protocol specific, but
defaults to localhost in all cases.
.. attr:: service_name
:default: zuul
The service name may be specified here. Multiple Zuul
installations should use different values.
.. attr:: tls_cert
The path to the PEM encoded certificate file. Used only by
:value:`tracing.protocol.grpc`.
.. attr:: tls_key
The path to the PEM encoded key file. Used only by
:value:`tracing.protocol.grpc`.
.. attr:: tls_ca
The path to the PEM encoded CA certificate file. Used only by
:value:`tracing.protocol.grpc`.
.. attr:: certificate_file
The path to the PEM encoded certificate file used to verify the
endpoint. Used only by :value:`tracing.protocol.http/protobuf`.
.. attr:: insecure
Whether to allow an insecure connection. Used only by
:value:`tracing.protocol.grpc`.
.. attr:: timeout
:default: 10000
The timeout for outgoing data in milliseconds.
.. attr:: compression
The compression algorithm to use. Available values depend on
the protocol and endpoint. The only universally supported value
is ``gzip``.
ZooKeeper
~~~~~~~~~
.. attr:: zookeeper
Client connection information for ZooKeeper. TLS is required.
.. attr:: hosts
:required:
A list of zookeeper hosts for Zuul to use when communicating
with Nodepool.
.. attr:: tls_cert
:required:
The path to the PEM encoded certificate file.
.. attr:: tls_key
:required:
The path to the PEM encoded key file.
.. attr:: tls_ca
:required:
The path to the PEM encoded CA certificate file.
.. attr:: session_timeout
:default: 10.0
The ZooKeeper session timeout, in seconds.
.. _database:
Database
~~~~~~~~
.. attr:: database
.. attr:: dburi
:required:
Database connection information in the form of a URI understood
by SQLAlchemy. See `The SQLAlchemy manual
<https://docs.sqlalchemy.org/en/latest/core/engines.html#database-urls>`_
for more information.
The driver will automatically set up the database creating and managing
the necessary tables. Therefore the provided user should have sufficient
permissions to manage the database. For example:
.. code-block:: sql
GRANT ALL ON my_database TO 'my_user'@'%';
.. attr:: pool_recycle
:default: 1
Tune the pool_recycle value. See `The SQLAlchemy manual on pooling
<http://docs.sqlalchemy.org/en/latest/core/pooling.html#setting-pool-recycle>`_
for more information.
.. attr:: table_prefix
:default: ''
The string to prefix the table names. This makes it possible to run
several zuul deployments against the same database. This can be useful
if you rely on external databases which are not under your control.
The default is to have no prefix.
.. _scheduler:
Scheduler
---------
The scheduler is the primary component of Zuul. The scheduler is a
scalable component; one or more schedulers must be running at all
times for Zuul to be operational. It receives events from any
connections to remote systems which have been configured, enqueues
items into pipelines, distributes jobs to executors, and reports
results.
The scheduler must be able to connect to the ZooKeeper cluster shared
by Zuul and Nodepool in order to request nodes. It does not need to
connect directly to the nodes themselves, however -- that function is
handled by the Executors.
It must also be able to connect to any services for which connections
are configured (Gerrit, GitHub, etc).
The following sections of ``zuul.conf`` are used by the scheduler:
.. attr:: web
.. attr:: root
:required:
The root URL of the web service (e.g.,
``https://zuul.example.com/``).
See :attr:`tenant.web-root` for additional options for
whitelabeled tenant configuration.
.. attr:: status_url
URL that will be posted in Zuul comments made to changes when
starting jobs for a change.
.. TODO: is this effectively required?
.. attr:: keystore
.. _keystore-password:
.. attr:: password
:required:
Encryption password for private data stored in Zookeeper.
.. attr:: scheduler
.. attr:: command_socket
:default: /var/lib/zuul/scheduler.socket
Path to command socket file for the scheduler process.
.. attr:: tenant_config
Path to :ref:`tenant-config` file. This attribute
is exclusive with :attr:`scheduler.tenant_config_script`.
.. attr:: tenant_config_script
Path to a script to execute and load the tenant
config from. This attribute is exclusive with
:attr:`scheduler.tenant_config`.
.. attr:: default_ansible_version
Default ansible version to use for jobs that doesn't specify a version.
See :attr:`job.ansible-version` for details.
.. attr:: log_config
Path to log config file.
.. attr:: pidfile
:default: /var/run/zuul/scheduler.pid
Path to PID lock file.
.. attr:: relative_priority
:default: False
A boolean which indicates whether the scheduler should supply
relative priority information for node requests.
In all cases, each pipeline may specify a precedence value which
is used by Nodepool to satisfy requests from higher-precedence
pipelines first. If ``relative_priority`` is set to ``True``,
then Zuul will additionally group items in the same pipeline by
pipeline queue and weight each request by its position in that
project's group. A request for the first change in a given
queue will have the highest relative priority, and the second
change a lower relative priority. The first change of each
queue in a pipeline has the same relative priority, regardless
of the order of submission or how many other changes are in the
pipeline. This can be used to make node allocations complete
faster for projects with fewer changes in a system dominated by
projects with more changes.
After the first 10 changes, the relative priority becomes more
coarse (batching groups of 10 changes at the same priority).
Likewise, after 100 changes they are batchen in groups of 100.
This is to avoid causing additional load with unecessary
priority changes if queues are long.
If this value is ``False`` (the default), then node requests are
sorted by pipeline precedence followed by the order in which
they were submitted. If this is ``True``, they are sorted by
pipeline precedence, followed by relative priority, and finally
the order in which they were submitted.
.. attr:: default_hold_expiration
:default: max_hold_expiration
The default value for held node expiration if not supplied. This
will default to the value of ``max_hold_expiration`` if not changed,
or if it is set to a higher value than the max.
.. attr:: max_hold_expiration
:default: 0
Maximum number of seconds any nodes held for an autohold request
will remain available. A value of 0 disables this, and the nodes
will remain held until the autohold request is manually deleted.
If a value higher than ``max_hold_expiration`` is supplied during
hold request creation, it will be lowered to this value.
.. attr:: prometheus_port
Set a TCP port to start the prometheus metrics client.
.. attr:: prometheus_addr
:default: 0.0.0.0
The IPv4 addr to listen for prometheus metrics poll.
To use IPv6, python>3.8 is required `issue24209 <https://bugs.python.org/issue24209>`_.
Merger
------
Mergers are an optional Zuul service; they are not required for Zuul
to operate, but some high volume sites may benefit from running them.
Zuul performs quite a lot of git operations in the course of its work.
Each change that is to be tested must be speculatively merged with the
current state of its target branch to ensure that it can merge, and to
ensure that the tests that Zuul perform accurately represent the
outcome of merging the change. Because Zuul's configuration is stored
in the git repos it interacts with, and is dynamically evaluated, Zuul
often needs to perform a speculative merge in order to determine
whether it needs to perform any further actions.
All of these git operations add up, and while Zuul executors can also
perform them, large numbers may impact their ability to run jobs.
Therefore, administrators may wish to run standalone mergers in order
to reduce the load on executors.
Mergers need to be able to connect to the ZooKeeper cluster as well as
any services for which connections are configured (Gerrit, GitHub,
etc).
The following section of ``zuul.conf`` is used by the merger:
.. attr:: merger
.. attr:: command_socket
:default: /var/lib/zuul/merger.socket
Path to command socket file for the merger process.
.. attr:: git_dir
:default: /var/lib/zuul/merger-git
Directory in which Zuul should clone git repositories.
.. attr:: git_http_low_speed_limit
:default: 1000
If the HTTP transfer speed is less then git_http_low_speed_limit for
longer then git_http_low_speed_time, the transfer is aborted.
Value in bytes, setting to 0 will disable.
.. attr:: git_http_low_speed_time
:default: 30
If the HTTP transfer speed is less then git_http_low_speed_limit for
longer then git_http_low_speed_time, the transfer is aborted.
Value in seconds, setting to 0 will disable.
.. attr:: git_timeout
:default: 300
Timeout for git clone and fetch operations. This can be useful when
dealing with large repos. Note that large timeouts can increase startup
and reconfiguration times if repos are not cached so be cautious when
increasing this value.
Value in seconds.
.. attr:: git_user_email
Value to pass to `git config user.email
<https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup>`_.
.. attr:: git_user_name
Value to pass to `git config user.name
<https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup>`_.
.. attr:: log_config
Path to log config file for the merger process.
.. attr:: pidfile
:default: /var/run/zuul/merger.pid
Path to PID lock file for the merger process.
.. attr:: prometheus_port
Set a TCP port to start the prometheus metrics client.
.. attr:: prometheus_addr
:default: 0.0.0.0
The IPv4 addr to listen for prometheus metrics poll.
To use IPv6, python>3.8 is required `issue24209 <https://bugs.python.org/issue24209>`_.
.. _executor:
Executor
--------
Executors are responsible for running jobs. At the start of each job,
an executor prepares an environment in which to run Ansible which
contains all of the git repositories specified by the job with all
dependent changes merged into their appropriate branches. The branch
corresponding to the proposed change will be checked out (in all
projects, if it exists). Any roles specified by the job will also be
present (also with dependent changes merged, if appropriate) and added
to the Ansible role path. The executor also prepares an Ansible
inventory file with all of the nodes requested by the job.
The executor also contains a merger. This is used by the executor to
prepare the git repositories used by jobs, but is also available to
perform any tasks normally performed by standalone mergers. Because
the executor performs both roles, small Zuul installations may not
need to run standalone mergers.
Executors need to be able to connect to the ZooKeeper cluster, any
services for which connections are configured (Gerrit, GitHub, etc),
as well as directly to the hosts which Nodepool provides.
Trusted and Untrusted Playbooks
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The executor runs playbooks in one of two execution contexts depending
on whether the project containing the playbook is a
:term:`config-project` or an :term:`untrusted-project`. If the
playbook is in a config project, the executor runs the playbook in the
*trusted* execution context, otherwise, it is run in the *untrusted*
execution context.
Both execution contexts use `bubblewrap`_ to create a namespace to
ensure that playbook executions are isolated and are unable to access
files outside of a restricted environment. The administrator may
configure additional local directories on the executor to be made
available to the restricted environment.
.. _bubblewrap: https://github.com/projectatomic/bubblewrap
.. _executor_security:
Security Considerations
~~~~~~~~~~~~~~~~~~~~~~~
Bubblewrap restricts access to files outside of the build environment
in both execution contexts. Operators may allow either read-only or
read-write access to additional paths in either the `trusted` context
or both contexts with additional options described below. Be careful
when adding additional paths, and consider that any `trusted` or
`untrusted` (as appropriate) playbook will have access to these paths.
If executors are configured to use WinRM certificates, these must be
made available to the bubblewrap environment in order for Ansible to
use them. This invariably makes them accessible to any playbook in
that execution context. Operators may want to consider only supplying
WinRM credentials to trusted playbooks and installing per-build
certificates in a pre-playbook; or using Ansible's experimental SSH
support instead of WinRM.
Local code execution is permitted on the executor, so if a
vulnerability in bubblewrap or the kernel allows for an escape from
the restricted environment, users may be able to escalate their
privileges and obtain access to any data or secrets available to the
executor.
Playbooks which run on the executor will have the same network access
as the executor itself. This should be kept in mind when considering
IP-based network access control within an organization. Zuul's
internal communication is via ZooKeeper which is authenticated and
secured by TLS certificates, so as long as these certificates are not
made available to jobs, users should not be able to access or disrupt
Zuul's internal communications. However, statsd is an unauthenticated
protocol, so a malicious user could emit false statsd information.
If the Zuul executor is running in a cloud environment with a network
metadata service, users may be able to access that service. If it
supplies credentials, they may be able to obtain those credentials and
access cloud resources. Operators should ensure that in these
environments, the executors are configured with appropriately
restricted IAM profiles.
Configuration
~~~~~~~~~~~~~
The following sections of ``zuul.conf`` are used by the executor:
.. attr:: executor
.. attr:: command_socket
:default: /var/lib/zuul/executor.socket
Path to command socket file for the executor process.
.. attr:: finger_port
:default: 7900
Port to use for finger log streamer.
.. attr:: state_dir
:default: /var/lib/zuul
Path to directory in which Zuul should save its state.
.. attr:: git_dir
:default: /var/lib/zuul/executor-git
Directory that Zuul should clone local git repositories to. The
executor keeps a local copy of every git repository it works
with to speed operations and perform speculative merging.
This should be on the same filesystem as
:attr:`executor.job_dir` so that when git repos are cloned into
the job workspaces, they can be hard-linked to the local git
cache.
.. attr:: job_dir
:default: /var/lib/zuul/builds
Directory that Zuul should use to hold temporary job directories.
When each job is run, a new entry will be created under this
directory to hold the configuration and scratch workspace for
that job. It will be deleted at the end of the job (unless the
`--keep-jobdir` command line option is specified).
This should be on the same filesystem as :attr:`executor.git_dir`
so that when git repos are cloned into the job workspaces, they
can be hard-linked to the local git cache.
.. attr:: log_config
Path to log config file for the executor process.
.. attr:: pidfile
:default: /var/run/zuul/executor.pid
Path to PID lock file for the executor process.
.. attr:: private_key_file
:default: ~/.ssh/id_rsa
SSH private key file to be used when logging into worker nodes.
.. note:: If you use an RSA key, ensure it is encoded in the PEM
format (use the ``-t rsa -m PEM`` arguments to
`ssh-keygen`).
.. attr:: default_username
:default: zuul
Username to use when logging into worker nodes, if none is
supplied by Nodepool.
.. attr:: winrm_cert_key_file
:default: ~/.winrm/winrm_client_cert.key
The private key file of the client certificate to use for winrm
connections to Windows nodes.
.. attr:: winrm_cert_pem_file
:default: ~/.winrm/winrm_client_cert.pem
The certificate file of the client certificate to use for winrm
connections to Windows nodes.
.. note:: Currently certificate verification is disabled when
connecting to Windows nodes via winrm.
.. attr:: winrm_operation_timeout_sec
:default: None. The Ansible default of 20 is used in this case.
The timeout for WinRM operations.
.. attr:: winrm_read_timeout_sec
:default: None. The Ansible default of 30 is used in this case.
The timeout for WinRM read. Increase this if there are intermittent
network issues and read timeout errors keep occurring.
.. _admin_sitewide_variables:
.. attr:: variables
Path to an Ansible variables file to supply site-wide variables.
This should be a YAML-formatted file consisting of a single
dictionary. The contents will be made available to all jobs as
Ansible variables. These variables take precedence over all
other forms (job variables and secrets). Care should be taken
when naming these variables to avoid potential collisions with
those used by jobs. Prefixing variable names with a
site-specific identifier is recommended. The default is not to
add any site-wide variables. See the :ref:`User's Guide
<user_jobs_sitewide_variables>` for more information.
.. attr:: manage_ansible
:default: True
Specifies wether the zuul-executor should install the supported ansible
versions during startup or not. If this is ``True`` the zuul-executor
will install the ansible versions into :attr:`executor.ansible_root`.
It is recommended to set this to ``False`` and manually install Ansible
after the Zuul installation by running ``zuul-manage-ansible``. This has
the advantage that possible errors during Ansible installation can be
spotted earlier. Further especially containerized deployments of Zuul
will have the advantage of predictable versions.
.. attr:: ansible_root
:default: <state_dir>/ansible-bin
Specifies where the zuul-executor should look for its supported ansible
installations. By default it looks in the following directories and uses
the first which it can find.
* ``<zuul_install_dir>/lib/zuul/ansible``
* ``<ansible_root>``
The ``ansible_root`` setting allows you to override the second location
which is also used for installation if ``manage_ansible`` is ``True``.
.. attr:: ansible_setup_timeout
:default: 60
Timeout of the ansible setup playbook in seconds that runs before
the first playbook of the job.
.. attr:: disk_limit_per_job
:default: 250
This integer is the maximum number of megabytes that any one job
is allowed to consume on disk while it is running. If a job's
scratch space has more than this much space consumed, it will be
aborted. Set to -1 to disable the limit.
.. attr:: trusted_ro_paths
List of paths, separated by ``:`` to read-only bind mount into
trusted bubblewrap contexts.
.. attr:: trusted_rw_paths
List of paths, separated by ``:`` to read-write bind mount into
trusted bubblewrap contexts.
.. attr:: untrusted_ro_paths
List of paths, separated by ``:`` to read-only bind mount into
untrusted bubblewrap contexts.
.. attr:: untrusted_rw_paths
List of paths, separated by ``:`` to read-write bind mount into
untrusted bubblewrap contexts.
.. attr:: load_multiplier
:default: 2.5
When an executor host gets too busy, the system may suffer
timeouts and other ill effects. The executor will stop accepting
more than 1 job at a time until load has lowered below a safe
level. This level is determined by multiplying the number of
CPU's by `load_multiplier`.
So for example, if the system has 2 CPUs, and load_multiplier
is 2.5, the safe load for the system is 5.00. Any time the
system load average is over 5.00, the executor will quit
accepting multiple jobs at one time.
The executor will observe system load and determine whether
to accept more jobs every 30 seconds.
.. attr:: max_starting_builds
:default: None
An executor is accepting up to as many starting builds as defined by the
:attr:`executor.load_multiplier` on systems with more than four CPU cores,
and up to twice as many on systems with four or less CPU cores. For
example, on a system with two CPUs: 2 * 2.5 * 2 - up to ten starting
builds may run on such executor; on systems with eight CPUs: 2.5 * 8 - up
to twenty starting builds may run on such executor.
On systems with high CPU/vCPU count an executor may accept too many
starting builds. This can be overwritten using this option providing a
fixed number of maximum starting builds on an executor.
.. attr:: min_avail_hdd
:default: 5.0
This is the minimum percentage of HDD storage available for the
:attr:`executor.state_dir` directory. The executor will stop accepting
more than 1 job at a time until more HDD storage is available. The
available HDD percentage is calculated from the total available
disk space divided by the total real storage capacity multiplied by
100.
.. attr:: min_avail_mem
:default: 5.0
This is the minimum percentage of system RAM available. The
executor will stop accepting more than 1 job at a time until
more memory is available. The available memory percentage is
calculated from the total available memory divided by the
total real memory multiplied by 100. Buffers and cache are
considered available in the calculation.
.. attr:: hostname
:default: hostname of the server
The executor needs to know its hostname under which it is reachable by
zuul-web. Otherwise live console log streaming doesn't work. In most cases
This is automatically detected correctly. But when running in environments
where it cannot determine its hostname correctly this can be overridden
here.
.. attr:: paused_on_start
:default: false
Whether the executor should start in a paused mode. Such executor will not
accept tasks until it is unpaused.
.. attr:: zone
:default: None
Name of the nodepool executor-zone to exclusively execute all jobs that
have nodes with the specified executor-zone attribute. As an example,
it is possible for nodepool nodes to exist in a cloud without public
accessable IP address. By adding an executor to a zone nodepool nodes
could be configured to use private ip addresses.
To enable this in nodepool, you'll use the node-attributes setting in a
provider pool. For example:
.. code-block:: yaml
pools:
- name: main
node-attributes:
executor-zone: vpn
.. attr:: allow_unzoned
:default: False
If :attr:`executor.zone` is set it by default only processes jobs with
nodes of that specific zone even if the nodes have no zone at all.
Enabling ``allow_unzoned`` lets the executor also take jobs with nodes
without zone.
.. attr:: merge_jobs
:default: True
To disable global merge job, set it to false. This is useful for zoned
executors that are running on slow network where you don't want them to
perform merge operations for any events. The executor will still perform
the merge operations required for the build they are executing.
.. attr:: sigterm_method
:default: graceful
Determines how the executor responds to a ``SIGTERM`` signal.
.. value:: graceful
Stop accepting new jobs and wait for all running jobs to
complete before exiting.
.. value:: stop
Abort all running jobs and exit as soon as possible.
.. attr:: prometheus_port
Set a TCP port to start the prometheus metrics client.
.. attr:: prometheus_addr
:default: 0.0.0.0
The IPv4 addr to listen for prometheus metrics poll.
To use IPv6, python>3.8 is required `issue24209 <https://bugs.python.org/issue24209>`_.
.. attr:: keystore
.. attr:: password
:required:
Encryption password for private data stored in Zookeeper.
.. attr:: merger
.. attr:: git_user_email
Value to pass to `git config user.email
<https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup>`_.
.. attr:: git_user_name
Value to pass to `git config user.name
<https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup>`_.
.. attr:: prometheus_port
Set a TCP port to start the prometheus metrics client.
.. attr:: prometheus_addr
:default: 0.0.0.0
The IPv4 addr to listen for prometheus metrics poll.
To use IPv6, python>3.8 is required `issue24209 <https://bugs.python.org/issue24209>`_.
.. attr:: ansible_callback "<name>"
To whitelist ansible callback ``<name>``. Any attributes found is this section
will be added to the ``callback_<name>`` section in ansible.cfg.
An example of what configuring the builtin mail callback would look like.
The configuration in zuul.conf.
.. code-block:: ini
[ansible_callback "mail"]
to = [email protected]
sender = [email protected]
Would generate the following in ansible.cfg:
.. code-block:: ini
[defaults]
callback_whitelist = mail
[callback_mail]
to = [email protected]
sender = [email protected]
.. _web-server:
Web Server
----------
.. TODO: Turn REST API into a link to swagger docs when we grow them
The Zuul web server serves as the single process handling all HTTP
interactions with Zuul. This includes the websocket interface for live
log streaming, the REST API and the html/javascript dashboard. All three are
served as a holistic web application. For information on additional supported
deployment schemes, see :ref:`web-deployment-options`.
Web servers need to be able to connect to the ZooKeeper cluster and
the SQL database. If a GitHub, Gitlab, or Pagure connection is
configured, they need to be reachable so they may receive
notifications.
In addition to the common configuration sections, the following
sections of ``zuul.conf`` are used by the web server:
.. attr:: web
.. attr:: command_socket
:default: /var/lib/zuul/web.socket
Path to command socket file for the web process.
.. attr:: listen_address
:default: 127.0.0.1
IP address or domain name on which to listen.
.. attr:: log_config
Path to log config file for the web server process.
.. attr:: pidfile
:default: /var/run/zuul/web.pid
Path to PID lock file for the web server process.
.. attr:: port
:default: 9000
Port to use for web server process.
.. attr:: websocket_url
Base URL on which the websocket service is exposed, if different
than the base URL of the web app.
.. attr:: stats_url
Base URL from which statistics emitted via statsd can be queried.
.. attr:: stats_type
:default: graphite
Type of server hosting the statistics information. Currently only
'graphite' is supported by the dashboard.
.. attr:: static_path
:default: zuul/web/static
Path containing the static web assets.
.. attr:: static_cache_expiry
:default: 3600
The Cache-Control max-age response header value for static files served
by the zuul-web. Set to 0 during development to disable Cache-Control.
.. attr:: zone
The zone in which zuul-web is deployed. This is only needed if
there are executors with different zones in the environment and
not all executors are directly addressable from zuul-web. The
parameter specifies the zone where the executors are directly
adressable. Live log streaming will go directly to the executors
of the same zone and be routed to a finger gateway of the target
zone if the zones are different.
In a mixed system (with zoned and unzoned executors) there may
also be zoned and unzoned zuul-web services. Omit the zone
parameter for any unzoned zuul-web servers.
If this is used the finger gateways should be configured accordingly.
.. attr:: keystore
.. attr:: password
:required:
Encryption password for private data stored in Zookeeper.
Authentication
~~~~~~~~~~~~~~
A user can be granted access to protected REST API endpoints by providing a
valid JWT (JSON Web Token) as a bearer token when querying the API endpoints.
JWTs are signed and therefore Zuul must be configured so that signatures can be
verified. More information about the JWT standard can be found on the `IETF's
RFC page <https://tools.ietf.org/html/rfc7519>`_.
This optional section of ``zuul.conf``, if present, will activate the
protected endpoints and configure JWT validation:
.. attr:: auth <authenticator name>
.. attr:: driver
The signing algorithm to use. Accepted values are ``HS256``, ``RS256``,
``RS256withJWKS`` or ``OpenIDConnect``. See below for driver-specific
configuration options.
.. attr:: allow_authz_override
:default: false
Allow a JWT to override predefined access rules. See the section on
:ref:`JWT contents <jwt-format>` for more details on how to grant access
to tenants with a JWT.
.. attr:: realm
The authentication realm.
.. attr:: default
:default: false
If set to ``true``, use this realm as the default authentication realm
when handling HTTP authentication errors.
.. attr:: client_id
The expected value of the "aud" claim in the JWT. This is required for
validation.
.. attr:: issuer_id
The expected value of the "iss" claim in the JWT. This is required for
validation.
.. attr:: uid_claim
:default: sub
The JWT claim that Zuul will use as a unique identifier for the bearer of
a token. This is "sub" by default, as it is usually the purpose of this
claim in a JWT. This identifier is used in audit logs.
.. attr:: max_validity_time
Optional value to ensure a JWT cannot be valid for more than this amount
of time in seconds. This is useful if the Zuul operator has no control
over the service issueing JWTs, and the tokens are too long-lived.
.. attr:: skew
:default: 0
Optional integer value to compensate for skew between Zuul's and the
JWT emitter's respective clocks. Use a negative value if Zuul's clock
is running behind.
This section can be repeated as needed with different authenticators, allowing
access to privileged API actions from several JWT issuers.
Driver-specific attributes
..........................
HS256
,,,,,
This is a symmetrical encryption algorithm that only requires a shared secret
between the JWT issuer and the JWT consumer (ie Zuul). This driver should be
used in test deployments, or in deployments where JWTs may be issued manually
to users.
.. note:: At least one HS256 authenticator should be configured in order to use admin commands with the Zuul command line interface.
.. attr:: secret
:noindex:
The shared secret used to sign JWTs and validate signatures.
RS256
,,,,,
This is an asymmetrical encryption algorithm that requires an RSA key pair. Only
the public key is needed by Zuul for signature validation.
.. attr:: public_key
The path to the public key of the RSA key pair. It must be readable by Zuul.
.. attr:: private_key
Optional. The path to the private key of the RSA key pair. It must be
readable by Zuul.
RS256withJWKS
,,,,,,,,,,,,,
.. warning::
This driver is deprecated, use ``OpenIDConnect`` instead.
Some Identity Providers use key sets (also known as **JWKS**), therefore the key to
use when verifying the Authentication Token's signatures cannot be known in
advance; the key's id is stored in the JWT's header and the key must then be
found in the remote key set.
The key set is usually available at a specific URL that can be found in the
"well-known" configuration of an OpenID Connect Identity Provider.
.. attr:: keys_url
The URL where the Identity Provider's key set can be found. For example, for
Google's OAuth service: https://www.googleapis.com/oauth2/v3/certs
OpenIDConnect
,,,,,,,,,,,,,
Use a third-party Identity Provider implementing the OpenID Connect protocol.
The issuer ID should be an URI, from which the "well-known" configuration URI
of the Identity Provider can be inferred. This is intended to be used for
authentication on Zuul's web user interface.
.. attr:: scope
:default: openid profile
The scope(s) to use when requesting access to a user's details. This attribute
can be multivalued (values must be separated by a space). Most OpenID Connect
Identity Providers support the default scopes "openid profile". A full list
of supported scopes can be found in the well-known configuration of the
Identity Provider under the key "scopes_supported".
.. attr:: keys_url
Optional. The URL where the Identity Provider's key set can be found.
For example, for Google's OAuth service: https://www.googleapis.com/oauth2/v3/certs
The well-known configuration of the Identity Provider should provide this URL
under the key "jwks_uri", therefore this attribute is usually not necessary.
Some providers may not conform to the JWT specification and further
configuration may be necessary. In these cases, the following
additional values may be used:
.. attr:: authority
:default: issuer_id
If the authority in the token response is not the same as the
issuer_id in the request, it may be explicitly set here.
.. attr:: audience
:default: client_id
If the audience in the token response is not the same as the
issuer_id in the request, it may be explicitly set here.
.. attr:: load_user_info
:default: true
If the web UI should skip accessing the "UserInfo" endpoint and
instead rely only on the information returned in the token, set
this to ``false``.
Client
------
Zuul's command line client may be configured to make calls to Zuul's web
server. The client will then look for a ``zuul.conf`` file with a ``webclient``
section to set up the connection over HTTP.
.. note:: At least one authenticator must be configured in Zuul for admin commands to be enabled in the client.
.. attr:: webclient
.. attr:: url
The root URL of Zuul's web server.
.. attr:: verify_ssl
:default: true
Enforce SSL verification when sending requests over to Zuul's web server.
This should only be disabled when working with test servers.
Finger Gateway
--------------
The Zuul finger gateway listens on the standard finger port (79) for
finger requests specifying a build UUID for which it should stream log
results. The gateway will determine which executor is currently running that
build and query that executor for the log stream.
This is intended to be used with the standard finger command line client.
For example::
finger [email protected]
The above would stream the logs for the build identified by `UUID`.
Finger gateway servers need to be able to connect to the ZooKeeper
cluster, as well as the console streaming port on the executors
(usually 7900).
Finger gateways are optional. They may be run for either or both of
the following purposes:
* Allowing end-users to connect to the finger port to stream logs.
* Providing an accessible log streaming port for remote zoned
executors which are otherwise inacessible.
In this case, log streaming requests from finger gateways or
zuul-web will route to the executors via finger gateways in the same
zone.
In addition to the common configuration sections, the following
sections of ``zuul.conf`` are used by the finger gateway:
.. attr:: fingergw
.. attr:: command_socket
:default: /var/lib/zuul/fingergw.socket
Path to command socket file for the executor process.
.. attr:: listen_address
:default: all addresses
IP address or domain name on which to listen.
.. attr:: log_config
Path to log config file for the finger gateway process.
.. attr:: pidfile
:default: /var/run/zuul/fingergw.pid
Path to PID lock file for the finger gateway process.
.. attr:: port
:default: 79
Port to use for the finger gateway. Note that since command line
finger clients cannot usually specify the port, leaving this set to
the default value is highly recommended.
.. attr:: user
User ID for the zuul-fingergw process. In normal operation as a
daemon, the finger gateway should be started as the ``root``
user, but if this option is set, it will drop privileges to this
user during startup. It is recommended to set this option to an
unprivileged user.
.. attr:: hostname
:default: hostname of the server
When running finger gateways in a multi-zone configuration, the
gateway needs to know its hostname under which it is reachable
by zuul-web. Otherwise live console log streaming doesn't
work. In most cases This is automatically detected
correctly. But when running in environments where it cannot
determine its hostname correctly this can be overridden here.
.. attr:: zone
The zone where the finger gateway is located. This is only needed for
live log streaming if the zuul deployment is spread over multiple
zones without the ability to directly connect to all executors from
zuul-web. See :attr:`executor.zone` for further information.
In a mixed system (with zoned and unzoned executors) there may
also be zoned and unzoned finger gateway services. Omit the zone
parameter for any unzoned finger gateway servers.
If the Zuul installation spans an untrusted network (for example, if
there are remote executor zones), it may be necessary to use TLS
between the components that handle log streaming (zuul-executor,
zuul-fingergw, and zuul-web). If so, set the following options.
Note that this section is also read by zuul-web in order to load a
client certificate to use when connecting to a finger gateway which
requires TLS, and it is also read by zuul-executor to load a server
certificate for its console streaming port.
If any of these are present, all three certificate options must be
provided.
.. attr:: tls_cert
The path to the PEM encoded certificate file.
.. attr:: tls_key
The path to the PEM encoded key file.
.. attr:: tls_ca
The path to the PEM encoded CA certificate file.
.. attr:: tls_verify_hostnames
:default: true
In the case of a private CA it may be both safe and convenient
to disable hostname checks. However, if the certificates are
issued by a public CA, hostname verification should be enabled.
.. attr:: tls_client_only
:default: false
In order to provide a finger gateway which can reach remote
finger gateways and executors which use TLS, but does not itself
serve end-users via TLS (i.e., it runs within a protected
network and users access it directly via the finger port), set
this to ``true`` and the finger gateway will not listen on TLS,
but will still use the supplied certificate to make remote TLS
connections.
.. _connections:
Connections
===========
Most of Zuul's configuration is contained in the git repositories upon
which Zuul operates, however, some configuration outside of git
repositories is still required to bootstrap the system. This includes
information on connections between Zuul and other systems, as well as
identifying the projects Zuul uses.
In order to interact with external systems, Zuul must have a
*connection* to that system configured. Zuul includes a number of
:ref:`drivers <drivers>`, each of which implements the functionality
necessary to connect to a system. Each connection in Zuul is
associated with a driver.
To configure a connection in Zuul, select a unique name for the
connection and add a section to ``zuul.conf`` with the form
``[connection NAME]``. For example, a connection to a gerrit server
may appear as:
.. code-block:: ini
[connection mygerritserver]
driver=gerrit
server=review.example.com
Zuul needs to use a single connection to look up information about
changes hosted by a given system. When it looks up changes, it will
do so using the first connection it finds that matches the server name
it's looking for. It's generally best to use only a single connection
for a given server, however, if you need more than one (for example,
to satisfy unique reporting requirements) be sure to list the primary
connection first as that is what Zuul will use to look up all changes
for that server.

:title: Zuul Admin Client
Zuul Admin Client
=================
Zuul includes a simple command line client that may be used to affect Zuul's
behavior while running.
.. note:: For operations related to normal workflow like enqueue, dequeue, autohold and promote, the `zuul-client` CLI should be used instead.
Configuration
-------------
The client uses the same zuul.conf file as the server, and will look
for it in the same locations if not specified on the command line.
Usage
-----
The general options that apply to all subcommands are:
.. program-output:: zuul-admin --help
The following subcommands are supported:
tenant-conf-check
^^^^^^^^^^^^^^^^^
.. program-output:: zuul-admin tenant-conf-check --help
Example::
zuul-admin tenant-conf-check
This command validates the tenant configuration schema. It exits '-1' in
case of errors detected.
create-auth-token
^^^^^^^^^^^^^^^^^
.. note:: This command is only available if an authenticator is configured in
``zuul.conf``. Furthermore the authenticator's configuration must
include a signing secret.
.. program-output:: zuul-admin create-auth-token --help
Example::
zuul-admin create-auth-token --auth-config zuul-operator --user alice --tenant tenantA --expires-in 1800
The return value is the value of the ``Authorization`` header the user must set
when querying a protected endpoint on Zuul's REST API.
Example::
bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJodHRwOi8vbWFuYWdlc2Yuc2ZyZG90ZXN0aW5zdGFuY2Uub3JnIiwienV1bC50ZW5hbnRzIjp7ImxvY2FsIjoiKiJ9LCJleHAiOjE1Mzc0MTcxOTguMzc3NTQ0fQ.DLbKx1J84wV4Vm7sv3zw9Bw9-WuIka7WkPQxGDAHz7s

Deprecated commands
-------------------
The following commands are deprecated in the zuul-admin CLI, and thus may not be entirely supported in Zuul's current version.
They will be removed in a future release of Zuul. They can still be performed via the `zuul-client` CLI.
Please refer to `zuul-client's documentation <https://zuul-ci.org/docs/zuul-client/>`__
for more details.
In order to run these commands, the ``webclient`` section is required in the configuration file.
It is also possible to run the client without a configuration file, by using the
``--zuul-url`` option to specify the base URL of the Zuul web server.
Autohold
^^^^^^^^
.. program-output:: zuul-admin autohold --help
Example::
zuul-admin autohold --tenant openstack --project example_project --job example_job --reason "reason text" --count 1
Autohold Delete
^^^^^^^^^^^^^^^
.. program-output:: zuul-admin autohold-delete --help
Example::
zuul-admin autohold-delete --id 0000000123
Autohold Info
^^^^^^^^^^^^^
.. program-output:: zuul-admin autohold-info --help

Enqueue
^^^^^^^
.. program-output:: zuul-admin enqueue --help
Example::
zuul-admin enqueue --tenant openstack --trigger gerrit --pipeline check --project example_project --change 12345,1
Note that the format of change id is <number>,<patchset>.
Enqueue-ref
^^^^^^^^^^^
.. program-output:: zuul-admin enqueue-ref --help
This command is provided to manually simulate a trigger from an
external source. It can be useful for testing or replaying a trigger
that is difficult or impossible to recreate at the source. The
arguments to ``enqueue-ref`` will vary depending on the source and
type of trigger. Some familiarity with the arguments emitted by
``gerrit`` `update hooks
<https://gerrit-review.googlesource.com/admin/projects/plugins/hooks>`__
such as ``patchset-created`` and ``ref-updated`` is recommended. Some
examples of common operations are provided below.
Manual enqueue examples
***********************
It is common to have a ``release`` pipeline that listens for new tags
coming from ``gerrit`` and performs a range of code packaging jobs.
If there is an unexpected issue in the release jobs, the same tag can
not be recreated in ``gerrit`` and the user must either tag a new
release or request a manual re-triggering of the jobs. To re-trigger
the jobs, pass the failed tag as the ``ref`` argument and set
``newrev`` to the change associated with the tag in the project
repository (i.e. what you see from ``git show X.Y.Z``)::
zuul-admin enqueue-ref --tenant openstack --trigger gerrit --pipeline release --project openstack/example_project --ref refs/tags/X.Y.Z --newrev abc123..
The command can also be used asynchronosly trigger a job in a
``periodic`` pipeline that would usually be run at a specific time by
the ``timer`` driver. For example, the following command would
trigger the ``periodic`` jobs against the current ``master`` branch
top-of-tree for a project::
zuul-admin enqueue-ref --tenant openstack --trigger timer --pipeline periodic --project openstack/example_project --ref refs/heads/master
Another common pipeline is a ``post`` queue listening for ``gerrit``
merge results. Triggering here is slightly more complicated as you
wish to recreate the full ``ref-updated`` event from ``gerrit``. For
a new commit on ``master``, the gerrit ``ref-updated`` trigger
expresses "reset ``refs/heads/master`` for the project from ``oldrev``
to ``newrev``" (``newrev`` being the committed change). Thus to
replay the event, you could ``git log`` in the project and take the
current ``HEAD`` and the prior change, then enqueue the event::
NEW_REF=$(git rev-parse HEAD)
OLD_REF=$(git rev-parse HEAD~1)
zuul-admin enqueue-ref --tenant openstack --trigger gerrit --pipeline post --project openstack/example_project --ref refs/heads/master --newrev $NEW_REF --oldrev $OLD_REF
Note that zero values for ``oldrev`` and ``newrev`` can indicate
branch creation and deletion; the source code is the best reference
for these more advanced operations.
Promote
^^^^^^^
.. program-output:: zuul-admin promote --help
Example::
zuul-admin promote --tenant openstack --pipeline gate --changes 12345,1 13336,3
Note that the format of changes id is <number>,<patchset>.
The promote action is used to reorder the changes in a pipeline, by
putting the provided changes at the top of the queue.
The most common use case for the promote action is the need to merge
an urgent fix when the gate pipeline has several patches queued
ahead. This is especially needed if there is concern that one or more
changes ahead in the queue may fail, thus increasing the time to land
for the fix; or concern that the fix may not pass validation if
applied on top of the current patch queue in the gate.
Any items in a dependent pipeline which have had items ahead of them
changed will have their jobs canceled and restarted based on the new
ordering.
If items in independent pipelines are promoted, no jobs will be
restarted, but their change queues within the pipeline will be
re-ordered so that they will be processed first and their node request
priorities will increase.

:title: Monitoring
Monitoring
==========
.. _statsd:
Statsd reporting
----------------
Zuul comes with support for the statsd protocol, when enabled and configured
(see below), the Zuul scheduler will emit raw metrics to a statsd receiver
which let you in turn generate nice graphics.
Configuration
~~~~~~~~~~~~~
Statsd support uses the ``statsd`` python module. Note that support
is optional and Zuul will start without the statsd python module
present.
Configuration is in the :attr:`statsd` section of ``zuul.conf``.
Metrics
~~~~~~~
These metrics are emitted by the Zuul :ref:`scheduler`:
.. stat:: zuul.event.<driver>.<type>
:type: counter
Zuul will report counters for each type of event it receives from
each of its configured drivers.
.. stat:: zuul.connection.<connection>
Holds metrics specific to connections. This hierarchy includes:
.. stat:: cache.data_size_compressed
:type: gauge
The number of bytes stored in ZooKeeper for all items in this
connection's change cache.
.. stat:: cache.data_size_uncompressed
:type: gauge
The number of bytes required to for the change cache (the
decompressed value of ``data_size_compressed``).
.. stat:: zuul.tenant.<tenant>.event_enqueue_processing_time
:type: timer
A timer metric reporting the time from when the scheduler receives
a trigger event from a driver until the corresponding item is
enqueued in a pipeline. This measures the performance of the
scheduler in dispatching events.
.. stat:: zuul.tenant.<tenant>.event_enqueue_time
:type: timer
A timer metric reporting the time from when a trigger event was
received from the remote system to when the corresponding item is
enqueued in a pipeline. This includes
:stat:`zuul.tenant.<tenant>.event_enqueue_processing_time` and any
driver-specific pre-processing of the event.
.. stat:: zuul.tenant.<tenant>.management_events
:type: gauge
The size of the tenant's management event queue.
.. stat:: zuul.tenant.<tenant>.reconfiguration_time
:type: timer
A timer metric reporting the time taken to reconfigure a tenant.
This is performed by one scheduler after a tenant reconfiguration
event is received. During this time, all processing of that
tenant's pipelines are halted. This measures that time.
Once the first scheduler completes a tenant reconfiguration, other
schedulers may update their layout in the background without
interrupting processing. That is not reported in this metric.
.. stat:: zuul.tenant.<tenant>.trigger_events
:type: gauge
The size of the tenant's trigger event queue.
.. stat:: zuul.tenant.<tenant>.pipeline
Holds metrics specific to jobs. This hierarchy includes:
.. stat:: <pipeline>
A set of metrics for each pipeline named as defined in the Zuul
config.
.. stat:: event_enqueue_time
:type: timer
The time elapsed from when a trigger event was received from
the remote system to when the corresponding item is enqueued
in a pipeline.
.. stat:: merge_request_time
:type: timer
The amount of time spent waiting for the initial merge
operation(s). This will always include a request to a Zuul
merger to speculatively merge the change, but it may also
include a second request submitted in parallel to identify
the files altered by the change. Includes
:stat:`zuul.tenant.<tenant>.pipeline.<pipeline>.merger_merge_op_time`
and
:stat:`zuul.tenant.<tenant>.pipeline.<pipeline>.merger_files_changes_op_time`.
.. stat:: merger_merge_op_time
:type: timer
The amount of time the merger spent performing a merge
operation. This does not include any of the round-trip time
from the scheduler to the merger, or any other merge
operations.
.. stat:: merger_files_changes_op_time
:type: timer
The amount of time the merger spent performing a files-changes
operation to detect changed files (this is sometimes
performed if the source does not provide this information).
This does not include any of the round-trip time from the
scheduler to the merger, or any other merge operations.
.. stat:: layout_generation_time
:type: timer
The amount of time spent generating a dynamic configuration layout.
.. stat:: job_freeze_time
:type: timer
The amount of time spent freezing the inheritance hierarchy
and parameters of a job.
.. stat:: repo_state_time
:type: timer
The amount of time waiting for a secondary Zuul merger
operation to collect additional information about the repo
state of required projects. Includes
:stat:`zuul.tenant.<tenant>.pipeline.<pipeline>.merger_repo_state_op_time`.
.. stat:: merger_repo_state_op_time
:type: timer
The amount of time the merger spent performing a repo state
operation to collect additional information about the repo
state of required projects. This does not include any of the
round-trip time from the scheduler to the merger, or any
other merge operations.
.. stat:: node_request_time
:type: timer
The amount of time spent waiting for each node request to be
fulfilled.
.. stat:: job_wait_time
:type: timer
How long a job waited for an executor to start running it
after the build was requested.
.. stat:: event_job_time
:type: timer
The total amount of time elapsed from when a trigger event
was received from the remote system until the item's first
job is run. This is only emitted once per queue item, even
if its buildset is reset due to a speculative execution
failure.
.. stat:: all_jobs
:type: counter
Number of jobs triggered by the pipeline.
.. stat:: current_changes
:type: gauge
The number of items currently being processed by this
pipeline.
.. stat:: handling
:type: timer
The total time taken to refresh and process the pipeline.
This is emitted every time a scheduler examines a pipeline
regardless of whether it takes any actions.
.. stat:: event_process
:type: timer
The time taken to process the event queues for the pipeline.
This is emitted only if there are events to process.
.. stat:: process
:type: timer
The time taken to process the pipeline. This is emitted only
if there were events to process.
.. stat:: data_size_compressed
:type: gauge
The number of bytes stored in ZooKeeper to represent the
serialized state of the pipeline.
.. stat:: data_size_uncompressed
:type: gauge
The number of bytes required to represent the serialized
state of the pipeline (the decompressed value of
``data_size_compressed``).
.. stat:: project
This hierarchy holds more specific metrics for each project
participating in the pipeline.
.. stat:: <canonical_hostname>
The canonical hostname for the triggering project.
Embedded ``.`` characters will be translated to ``_``.
.. stat:: <project>
The name of the triggering project. Embedded ``/`` or
``.`` characters will be translated to ``_``.
.. stat:: <branch>
The name of the triggering branch. Embedded ``/`` or
``.`` characters will be translated to ``_``.
.. stat:: job
Subtree detailing per-project job statistics:
.. stat:: <jobname>
The triggered job name.
.. stat:: <result>
:type: counter, timer
A counter for each type of result (e.g., ``SUCCESS`` or
``FAILURE``, ``ERROR``, etc.) for the job. If the
result is ``SUCCESS`` or ``FAILURE``, Zuul will
additionally report the duration of the build as a
timer.
.. stat:: wait_time
:type: timer
How long the job waited for an executor to
start running it after the build was requested.
.. stat:: current_changes
:type: gauge
The number of items of this project currently being
processed by this pipeline.
.. stat:: resident_time
:type: timer
A timer metric reporting how long each item for this
project has been in the pipeline.

.. stat:: zuul.executor.<executor>
Holds metrics emitted by individual executors. The ``<executor>``
component of the key will be replaced with the hostname of the
executor.
.. stat:: merger.<result>
:type: counter
Incremented to represent the status of a Zuul executor's merger
operations. ``<result>`` can be either ``SUCCESS`` or ``FAILURE``.
A failed merge operation which would be accounted for as a ``FAILURE``
is what ends up being returned by Zuul as a ``MERGE_CONFLICT``.
.. stat:: builds
:type: counter
Incremented each time the executor starts a build.
.. stat:: starting_builds
:type: gauge, timer
The number of builds starting on this executor and a timer containing
how long jobs were in this state. These are builds which have not yet
begun their first pre-playbook.
The timer needs special thoughts when interpreting it because it
aggregates all jobs. It can be useful when aggregating it over a longer
period of time (maybe a day) where fast rising graphs could indicate e.g.
IO problems of the machines the executors are running on. But it has to
be noted that a rising graph also can indicate a higher usage of complex
jobs using more required projects. Also comparing several executors might
give insight if the graphs differ a lot from each other. Typically the
jobs are equally distributed over all executors (in the same zone when
using the zone feature) and as such the starting jobs timers (aggregated
over a large enough interval) should not differ much.
.. stat:: running_builds
:type: gauge
The number of builds currently running on this executor. This
includes starting builds.
.. stat:: paused_builds
:type: gauge
The number of currently paused builds on this executor.
.. stat:: phase
Subtree detailing per-phase execution statistics:
.. stat:: <phase>
``<phase>`` represents a phase in the execution of a job.
This can be an *internal* phase (such as ``setup`` or ``cleanup``) as
well as *job* phases such as ``pre``, ``run`` or ``post``.
.. stat:: <result>
:type: counter
A counter for each type of result.
These results do not, by themselves, determine the status of a build
but are indicators of the exit status provided by Ansible for the
execution of a particular phase.
Example of possible counters for each phase are: ``RESULT_NORMAL``,
``RESULT_TIMED_OUT``, ``RESULT_UNREACHABLE``, ``RESULT_ABORTED``.
.. stat:: load_average
:type: gauge
The one-minute load average of this executor, multiplied by 100.
.. stat:: pause
:type: gauge
Indicates if the executor is paused. 1 means paused else 0.
.. stat:: pct_used_hdd

.. stat:: pct_used_ram
:type: gauge
The used RAM (excluding buffers and cache) on this executor, as
a percentage multiplied by 100.
.. stat:: pct_used_ram_cgroup
:type: gauge
The used RAM (excluding buffers and cache) on this executor allowed by
the cgroup, as percentage multiplied by 100.
.. stat:: zuul.nodepool.requests
Holds metrics related to Zuul requests and responses from Nodepool.
States are one of:
*requested*
Node request submitted by Zuul to Nodepool
*canceled*
Node request was canceled by Zuul
*failed*
Nodepool failed to fulfill a node request
*fulfilled*
Nodes were assigned by Nodepool
.. stat:: <state>
:type: timer
Records the elapsed time from request to completion for states
`failed` and `fulfilled`. For example,
``zuul.nodepool.request.fulfilled.mean`` will give the average
time for all fulfilled requests within each ``statsd`` flush
interval.
A lower value for `fulfilled` requests is better. Ideally,
there will be no `failed` requests.
.. stat:: <state>.total
:type: counter
Incremented when nodes are assigned or removed as described in
the states above.
.. stat:: <state>.size.<size>
:type: counter, timer
Increments for the node count of each request. For example, a
request for 3 nodes would use the key
``zuul.nodepool.requests.requested.size.3``; fulfillment of 3
node requests can be tracked with
``zuul.nodepool.requests.fulfilled.size.3``.
The timer is implemented for ``fulfilled`` and ``failed``
requests. For example, the timer
``zuul.nodepool.requests.failed.size.3.mean`` gives the average
time of 3-node failed requests within the ``statsd`` flush
interval. A lower value for `fulfilled` requests is better.
Ideally, there will be no `failed` requests.
.. stat:: <state>.label.<label>
:type: counter, timer
Increments for the label of each request. For example, requests
for `centos7` nodes could be tracked with
``zuul.nodepool.requests.requested.centos7``.
The timer is implemented for ``fulfilled`` and ``failed``
requests. For example, the timer
``zuul.nodepool.requests.fulfilled.label.centos7.mean`` gives
the average time of ``centos7`` fulfilled requests within the
``statsd`` flush interval. A lower value for `fulfilled`
requests is better. Ideally, there will be no `failed`
requests.
.. stat:: zuul.nodepool
.. stat:: current_requests
:type: gauge
The number of outstanding nodepool requests from Zuul. Ideally
this will be at zero, meaning all requests are fulfilled.
Persistently high values indicate more testing node resources
would be helpful.
.. stat:: tenant.<tenant>.current_requests
:type: gauge
The number of outstanding nodepool requests from Zuul drilled down by
<tenant>. If a tenant for a node request cannot be determed, it is
reported as ``unknown``. This relates to
``zuul.nodepool.current_requests``.
.. stat:: zuul.nodepool.resources

of nodes are reported by nodepool.
.. stat:: in_use
Holds metrics about resources currently in use by a build.
.. stat:: tenant

.. stat:: <project>.<resource>
:type: counter, gauge
Counter with the summed usage by project as <resource> seconds and
gauge with the currently used resources by project.

This is a copy of :stat:`zuul.executors.unzoned`. It does not
include information about zoned executors.
.. warning:: The metrics at this location are deprecated and will

handler iteration.
.. stat:: time_query
:type: timer
Each time the scheduler performs a query against the SQL
database in order to determine an estimated time for a job, it
emits this timer of the duration of the query. Note this is a
performance metric of how long the SQL query takes; it is not
the estimated time value itself.

As an example, given a job named `myjob` in `mytenant` triggered by a
change to `myproject` on the `master` branch in the `gate` pipeline
which took 40 seconds to build, the Zuul scheduler will emit the
following statsd events:
* ``zuul.tenant.mytenant.pipeline.gate.project.example_com.myproject.master.job.myjob.SUCCESS`` +1
* ``zuul.tenant.mytenant.pipeline.gate.project.example_com.myproject.master.job.myjob.SUCCESS`` 40 seconds
* ``zuul.tenant.mytenant.pipeline.gate.all_jobs`` +1
Prometheus monitoring
---------------------
Zuul comes with support to start a prometheus_ metric server to be added as
prometheus's target.
.. _prometheus: https://prometheus.io/docs/introduction/overview/
Configuration
~~~~~~~~~~~~~
To enable the service, set the ``prometheus_port`` in a service section of
``zuul.conf``. For example setting :attr:`scheduler.prometheus_port` to 9091
starts a HTTP server to expose metrics to a prometheus services at:
http://scheduler:9091/metrics
Metrics
~~~~~~~
These metrics are exposed by default:
.. stat:: process_virtual_memory_bytes
:type: gauge
.. stat:: process_resident_memory_bytes
:type: gauge
.. stat:: process_open_fds
:type: gauge
.. stat:: process_start_time_seconds
:type: gauge
.. stat:: process_cpu_seconds_total
:type: counter
On web servers the following additional metrics are exposed:
.. stat:: web_threadpool_idle
:type: gauge
The number of idle workers in the thread pool.
.. stat:: web_threadpool_queue
:type: gauge
The number of requests queued for thread pool workers.
.. stat:: web_streamers
:type: gauge
The number of log streamers currently in operation.
.. _prometheus_liveness:
Liveness Probes
~~~~~~~~~~~~~~~
The Prometheus server also supports liveness and ready probes at the
following URIS:
.. path:: health/live
Returns 200 as long as the process is running.
.. path:: health/ready
Returns 200 if the process is in `RUNNING` or `PAUSED` states.
Otherwise, returns 503. Note that 503 is returned for
`INITIALIZED`, so this may be used to determine when a component
has completely finished loading configuration.
.. path:: health/status
This always returns 200, but includes the component status as the
text body of the response.
