Jenkins Job Builder


Jenkins Job Builder takes simple descriptions of Jenkins jobs in YAML or JSON format and uses them to configure Jenkins. You can keep your job descriptions in human readable text format in a version control system to make changes and auditing easier. It also has a flexible template system, so creating many similarly configured jobs is easy.

To install:

$ pip install --user jenkins-job-builder

Bug report:



git clone

A virtual environment is recommended for development. For example, Jenkins Job Builder may be installed from the top level directory:

$ virtualenv .venv
$ source .venv/bin/activate
$ pip install -r test-requirements.txt -e .

Writing a patch

We ask that all code submissions be pep8 and pyflakes clean. The easiest way to do that is to run tox before submitting code for review in Gerrit. It will run pep8 and pyflakes in the same manner as the automated test suite that will run on proposed patchsets.

When creating new YAML components, please observe the following style conventions:

  • All YAML identifiers (including component names and arguments) should be lower-case and multiple word identifiers should use hyphens. E.g., “build-trigger”.
  • The Python functions that implement components should have the same name as the YAML keyword, but should use underscores instead of hyphens. E.g., “build_trigger”.

This consistency will help users avoid simple mistakes when writing YAML, as well as developers when matching YAML components to Python implementation.

Unit Tests

Unit tests have been included and are in the tests folder. Many unit tests samples are included as examples in our documentation to ensure that examples are kept current with existing behaviour. To run the unit tests, execute the command:

tox -e py34,py27
  • Note: View tox.ini to run tests on other versions of Python, generating the documentation and additionally for any special notes on running the test to validate documentation external URLs from behind proxies.

Installing without

For YAML support, you will need libyaml installed.

Mac OS X:

$ brew install libyaml

Then install the required python packages using pip:

$ sudo pip install PyYAML python-jenkins
