E.g.: jenkins-jobs test < config/jenkins.yml This is convenient for demoing or implementing functional tests. Change-Id: I4e3030e261d3b90f75e4a033ea074d18764d97bf

Installation
To install Jenkins Job Builder, run:
sudo python setup.py install
The OpenStack project uses Puppet to manage its infrastructure systems, including Jenkins. If you use Puppet, you can use the OpenStack Jenkins module to install Jenkins Job Builder.
Documentation
Documentation is included in the doc
folder. To generate
docs locally execute the command:
tox -e doc
The generated documentation is then available under
doc/build/html/index.html
.
Unit Tests
Unit tests have been included and are in the tests
folder. We recently started including unit tests as examples in our
documentation so to keep the examples up to date it is very important
that we include unit tests for every module. To run the unit tests,
execute the command:
tox -e py27
- Note: View
tox.ini
to run tests on other versions of Python.
Configuration File
After installation, you will need to create a configuration file. By
default, jenkins-jobs
looks in
/etc/jenkins_jobs/jenkins_jobs.ini
but you may specify an
alternative location when running jenkins-jobs
. The file
should have the following format:
../../etc/jenkins_jobs.ini-sample
- user
-
This should be the name of a user previously defined in Jenkins. Appropriate user permissions must be set under the Jenkins security matrix: under the
Global
group of permissions, checkRead
, then under theJob
group of permissions, checkCreate
,Delete
,Configure
and finallyRead
. - password
-
The API token for the user specified. You can get this through the Jenkins management interface under
People
-> username ->Configure
and then click theShow API Token
button. - url
-
The base URL for your Jenkins installation.
- ignore_cache
-
(Optional) If set to True, Jenkins Job Builder won't use any cache.
Running
After it's installed and configured, you can invoke Jenkins Job
Builder by running jenkins-jobs
. You won't be able to do
anything useful just yet without a configuration which is discussed in
the next section.
Usage
jenkins-jobs --help
Testing JJB
Once you have a configuration defined, you can test the job builder by running:
jenkins-jobs test /path/to/config -o /path/to/output
which will write XML files to the output directory for all of the jobs defined in the configuration directory.
If you want to run a simple test with just a single YAML file and see the XML output on stdout:
jenkins-jobs test /path/to/config
Updating Jenkins
When you're satisfied with the generated XML from the test, you can run:
jenkins-jobs update /path/to/config
which will upload the configurations to Jenkins if needed. Jenkins Job Builder maintains, for each host, a cache1 of previously configured jobs, so that you can run that command as often as you like, and it will only update the configuration in Jenkins if the defined configuration has changed since the last time it was run. Note: if you modify a job directly in Jenkins, jenkins-jobs will not know about it and will not update it.
To update a specific list of jobs, simply pass them as additional arguments after the configuration path. To update Foo1 and Foo2 run:
jenkins-jobs update /path/to/config Foo1 Foo2
Footnotes
The cache default location is at
~/.cache/jenkins_jobs
, which can be overridden by setting theXDG_CACHE_HOME
environment variable.↩︎
