jenkins-rails

jenkins-rails is a Ruby gem to automate configuration tasks of a Rails app on Jenkins CI server. The configuration will be just as easy as adding a .yml file to the Rails config folder, then run rake task to set it up on Jenkins.

Installation

Add this line to your application's Gemfile:

gem 'jenkins-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jenkins-rails

Usage

Configuration

Create jenkins.yml file (with erb) as following structure and put to Rails config folder:

    username: <%= ENV['JENKINS_USERNAME'] %>
    password: <%= ENV['JENKINS_PASSWORD'] %>
    host:     <%= ENV['JENKINS_HOST']     %>
    port:     80                                       #optional, default is 8080
    jobs:
      -
        name:         'Job 1'    #compulsory
        scm_provider: 'git'      #compulsory
        scm_url:      'git://github.com/apraditya/sampleapp.git'  #compulsory
        scm_branch:   'master'   #optional, default is 'master' if scm is git
        shell_script: 'relative/path/to/build/script'  #optional, details below
        keep_dependencies:                    false    #optional, default is 'false'
        block_build_when_downstream_building: false    #optional, default is 'false'
        block_build_when_upstream_building:   false    #optional, default is 'false'
        concurrent_build:                     false    #optional, default is 'false'
        child_projects:                       ~        #optional, default is 'null'
        child_threshold:                      failure  #optional, value is 'success', 'failure', or 'unstable'
                                                       # default is 'failure'
      -
        name:         'Job 2' 
        ...

The option shell_script can be configured with the relative path of the build script from Rails app root path, e.g. 'script/jenkins_build_script', 'config/jenkins_build_script' ...

Rake task

After adding the jenkins.yml to Rails app config folder, run the following rake task to configure Jenkins jobs

rake jenkins:configure

If username and password in jenkins.yml are empty or the environment variables are not set, the rake task can be run as following:

rake jenkins:configure[jenkins_username, jenkins_password]

For more details, have a look at rake -T in your Rails app.
