Continuous integration

Jenkins is an award-winning application that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Jenkins focuses on building/testing software projects continuously (e.g., like CruiseControl) and monitoring executions of externally-run jobs.

Stable version: 18.0 (changelog)

This appliance includes all the standard features in TurnKey Core, and on top of that:

  • Jenkins configurations:
    • Jenkins is installed from the Long Term Support package repository managed directly by the Jenkins project.

      Security note: Updates to Jenkins may require supervision so they ARE NOT configured to install automatically. See below for updating Jenkins.

    • Jenkins is preconfigured to use PAM authentication. Default user (as of v16.0) is jenkins-admin.
    • Includes all popular VCS clients and related Jenkins plugins for Git, Bazaar, Mercurial and Subversion.
    • JENKINS_HOME configured in environment: /var/lib/jenkins.
    • jenkins-cli bash wrapper script - can now use 'jenkins-cli' instead of 'java -jar path/to/jenkins-cli.jar' (convenience).
  • SSL support out of the box.
  • Includes postfix MTA (bound to localhost) for sending of email (e.g. password recovery).
  • Webmin modules for configuring Apache and Postfix.
