Steps for setting up Ruby CI on Jenkins running on EC2 micro instance, Ubuntu 12.04.

  1. sudo apt-get update
  2. Install jre/jdk
    • sudo apt-get install openjdk-6-jre openjdk-6-jdk
  3. Install jenkins
  4. Switch user to jenkins user
    • sudo su - jenkins
  5. Install git
    • sudo apt-get git-core
  6. Set jenkins git user/email
    • git config --global user.email "jenkins@none.com"
    • git config --global user.name "jenkins"
  7. Install rvm and install/use ruby 1.9.2 as jenkins user (takes ages...)
  8. Setup jenkins project and add bash script build step to call rake (needs all lines to set paths, install bundler, get gems, run rake)
    • #!/bin/bash
      source ~/.bash_profile
      rvm use 1.9.2
      gem install bundler
      bundle install
      bundle exec rake

Call explicit rake tasks to change build steps to perform build/deploy tasks.
