I've been working on learning puppet and using it to set up a jenkins box. I'm wiring jenkins through tomcat, since I may also end up running other webapps on there.

EDIT: I've installed (via puppet module install puppetlabs-stdlib) the stdlib provided by puppetlabs to use the file_line type.

This is puppet module manifest for setting up jenkins and tomcat and wiring the two together.

class tomcat_jenkins {
  package{'java-1.7':
    ensure => installed,
    name   => 'java-1.7.0-openjdk',
  }

  package{'tomcat6':
    ensure  => installed,
    require => Package['java-1.7'],
  }

  package{'jenkins':
    ensure  => installed,
    require => Yumrepo['jenkins'],
  }

  file{'jenkins-symlink':
    name    => '/usr/share/tomcat6/webapps/jenkins.war',
    require => [Package['tomcat6'], Package['jenkins']],
    ensure  => link,
    target  => '/usr/lib/jenkins/jenkins.war',
  }

  file{ '/srv':
    ensure => directory,
    owner  => 'root',
    group  => 'root',
  }

  file{ '/srv/jenkins':
    ensure  => directory,
    owner   => 'tomcat',
    group   => 'tomcat',
    require => Package['tomcat6'],
  }

  file_line{'jenkins_home':
    ensure  => present,
    path    => '/etc/tomcat6/tomcat6.conf',
    line    => 'JENKINS_HOME=/srv/jenkins',
    require => [Package['tomcat6'], File['/srv/jenkins']],
  }

  service{'tomcat6':
    ensure    => running,
    enable    => true,
    require   => [Package['tomcat6'], Package['jenkins'], File_line['jenkins_home']],
    subscribe => [Package['jenkins'], File['jenkins-symlink']],
  }

}

I see the output from the puppet agent that it is properly applying the catalog, and it pretends like it went ahead and applied the changes, but there's no /jenkins/ in my /etc/tomcat6/tomcat6.conf file. I don't have anything else managing that file.

puppet agent -t -d output:

Asking around on #puppet on irc.freenode.net, I found out that I was missing a configuration parameter on the puppet agent. I needed:

pluginsync=true

in the [main] section. After adding that line, it happily downloaded the plugins, and set up my stuff. Win.

  • You can also use --pluginsync if you're messing on the command line. – gak Dec 22 '12 at 8:12
