Recently a co-worker of mine (Thanks Ken Erwin) introduced me to Jenkins Job Builder (http://docs.openstack.org/infra/jenkins-job-builder/) which is a project created by the OpenStack infrastructure team that aims to automate the creation of Jenkins Jobs. The software is written in python and utilizes either yaml or json files as the framework for creating Jenkins jobs. A list of some of the primary features is provided below.

Features:

• Supports job creation, modification, and deletion
• Supports templates to speed up the creation of similar jobs
• Supports all major plugins as well as extending the software to incorporate additional plugins
• The software has built-in test functionality to test changes before being deployed into production
• Many additional features

Example:

The following section covers an example job in yaml format.

- job:
    name: puppet-module-profiles
    project-type: matrix

        sequential: true

           - 3.8.4
           - 4.0.0
           - 4.1.0
      - axis:
         type: slave
         name: nodes
         values:
