Continuous integration

RailsAdmin uses Hudson as its continuous integration server.

RailsAdmin is tested with

  • jruby-1.6.3 [ linux-i386-java ]
  • rbx-1.2.4-20110705 [ ]
  • ree-1.8.7-2011.03 [ i386 ]
  • ruby-1.8.7-p352 [ i386 ]
  • ruby-1.9.2-p290 [ i386 ]

and

  • MySQL
  • PostgreSQL
  • SQLite3

This document describes the Hudson setup used with RailsAdmin in case there's need to duplicate it manually.

Installing Hudson on Ubuntu

  1. Install key for the hudson repository:
   wget -O - http://hudson-ci.org/debian/hudson-ci.org.key | sudo apt-key add -
  1. Add Hudson as source to /etc/apt/sources.list:
   deb http://hudson-ci.org/debian binary/
  1. Install Hudson:
   sudo apt-get update
   sudo apt-get install hudson
  1. Install ruby1.9-dev to enable native extension building on Rubinius:
   sudo apt-get install ruby1.9-dev
  1. Install RVM for the user hudson with rubies 1.8.7, 1.9.2, jruby, rbx-1.2.3 and ree. Also install bundler gem for each ruby.

  2. Start Hudson:

   sudo /etc/init.d/hudson start
  1. Hudson should be now accessible with a web browser at:
   http://YOUR_SERVER_IP:8080/

Secure Hudson

  1. Go to Manage Hudson > Configure system

  2. Check Enable security

  3. Select Disable for TCP port for JNLP slave agents

  4. Select Hudson's own user database

  5. Select Matrix-based security

  6. Create user Neo ;)

  7. Check all ACL rules in the table for user Neo

  8. Select only Overall > Read and Job > Read for system user Anonymous

  9. Check Prevent Cross Site Request Forgery exploits

  10. Save (Button is in the very bottom of the screen)

  11. Go to Manage Hudson > Manage Users

  12. Create user with username Neo

Configure Hudson:

  1. Install following plugins via Manage Hudson > Manage plugins
    Hudson CVS Plug-in
    Git Plugin
    Github plugin
    Locale plugin
    Maven Integration plugin
    Hudson Rake plugin
    Hudson Ruby Plugin
    Hudson ruby metrics plugin
    Hudson SSH Slaves plugin
    Subversion Plugin
  1. Go to Manage Hudson > Configure system

  2. Type 1 in to # of executors to lower CPU usage.

  3. Type 1800 in to Quiet period which will make Hudson wait half an hour before starting builds. This will conserve CPU and disk usage a lot during times when commits get pushed at high rate as each new build request during the quiet period will reset the build stack and restart quiet period.

  4. Type en in to Locale => Default Language and check Ignore browser preference and force this language to all users. Note: At the time of writing Finnish translation was incomplete and confusing so I wanted to disable translations completely.

  5. Save (Button is in the very bottom of the screen)

Create a job for RailsAdmin:

  1. Click New Job link on Hudson frontpage

  2. Type RailsAdmin as the Job name, select Build free-style software project and click Ok

  3. Fill in settings:

    Github project [ https://github.com/sferik/rails_admin/ ]


    [*] Discard Old Builds
    Max number of builds to keep [ 10 ]


    Source Code Management

    [*] Git
    Repositories        URL of repository [ git://github.com/sferik/rails_admin.git ]
    Branches to build   Branch Specifier (blank for default) [ master ]
    Repository browser  (githubweb)
                        URL [ https://github.com/sferik/rails_admin/ ]


    Build Triggers

    [*] Trigger builds remotely (e.g., from scripts)
    Authentication Token [ INSERT A RANDOM TOKEN HERE ]


    Configuration Matrix

    User-defined Axis
    Name   [ CI_RUBY_VERSION ]
    Values [ 1.9.2 1.8.7 ree jruby rbx-1.2.3 ]

    User-defined Axis
    Name   [ CI_DB_ADAPTER ]
    Values [ sqlite3 postgresql mysql ]

    [*] Run each configuration sequentially


    Build

    Execute shell
    Command [ bash -l -c "rvm use $CI_RUBY_VERSION && export CI_DB_ADAPTER=$CI_DB_ADAPTER && rm -f Gemfile.lock && bundle install && cd spec/dummy_app && rm -f Gemfile.lock && bundle install && bundle exec rake rails_admin:prepare_ci_env --trace && cd ../../ && bundle exec rake spec --trace" ]
  1. Save the job

Automate continuous integration with a GitHub post-receive hook:

  1. Goto RailsAdmin repository's administrative view in GitHub

  2. Select Service Hooks and add a Post-Receive URLs type service hook from Available Service Hooks

  3. Type http://YOUR_SERVER_IP:8080/job/RailsAdmin/build?token=YOUR_TOKEN to URL

Additional tasks not covered in this document

  • Install Postgres 9.0, create user rails_admin and database ci_rails_admin
  • Install MySQL 5.1 (+ dev package for the mysql gem), create user rails_admin and database ci_rails_admin
  • Configure Nginx as proxy for Hudson accessible at http://ci.railsadmin.org

Postscript

The first part of this documentation was written after the actual installation, so there may be factual errors. The most important part though is the job settings, and that has been copied directly from working Hudson installation and is correct.

Something went wrong with that request. Please try again.
