Jenkins

Jenkins CI is a sweet continuous integration platform. Jenkins.rb makes it easy to get started, add/remove Ruby jobs and slave nodes; either from a CLI or an API.

Install

gem install jenkins

You do not need to download Jenkins CI. It is bundled in the RubyGem.

Example

Jenkins.rb is continuously tested using Jenkins at http://jenkins.thefrontside.net/job/jenkins.rb/.

The jenkins application allows you to see the projects/jobs and their statuses:

$ jenkins list --host jenkins.thefrontside.net --port 80
jenkins.rb - http://jenkins.thefrontside.net/job/jenkins.rb/
TheRubyRacer - http://jenkins.thefrontside.net/job/TheRubyRacer/

Alternately use environment variables:

$ JENKINS_HOST=jenkins.thefrontside.net JENKINS_PORT=80 jenkins list

Alternately, it will remember the last Jenkins CI master used.

$ jenkins list

Usage

To run your own Jenkins server (by default opens at http://localhost:3001):

Usage: jenkins server [options]
  -p,  --port [3001]                         run jenkins server on this port
  -c,  --control [3002]                      set the shutdown/control port
       --daemon                              fork into background and run as a daemon
       --logfile [PATH]                      redirect log messages to this file
  -k,  --kill                                send shutdown signal to control port
       --home [/Users/drnic/.jenkins/server]  use this directory to store server data

The remaining CLI tasks are for communicating with a running Jenkins server; either the one created above or hosted remotely.

Jobs

To list Jobs/Projects on a Jenkins server:

Usage: jenkins list [options]

To add Jobs/Projects (create a Job) on a Jenkins server:

Usage: jenkins create PROJECT_PATH [options]
    --public-scm                          use public scm URL
    --template [ruby]                     template of job steps (available: rails,rails3,ruby,rubygem,erlang)
    --assigned-node [ASSIGNED-NODE]       only use slave nodes with this label
    --override                            override if job exists
    --no-build                            create job without initial build

To trigger a Job to build:

Usage: jenkins build

To remove a Job from a Jenkins server:

Usage: jenkins remove PROJECT_PATH

Slave nodes

To list slaves on a Jenkins server (including itself):

Usage: jenkins nodes

To add a remote machine/remote VM to a Jenkins server as a slave:

Usage: jenkins add_node SLAVE_HOST
    --slave-port [22]             SSH port for Jenkins to connect to slave node
    --label [LABEL]               Labels for a job --assigned_node to match against to select a slave.         --master-key [MASTER-KEY]      Location of master public key or identity file
    --slave-fs [SLAVE-FS]         Location of file system on slave for Jenkins to use
    --name [NAME]                 Name of slave node (default SLAVE_HOST)
    --slave-user [deploy]         SSH user for Jenkins to connect to slave node

Selecting a Jenkins CI server

For all client-side commands, there are --host and --port options flags. These are cached after first used, so are only required for the first request to a Jenkins CI server. For example:

jenkins create . --host localhost --port 3001
jenkins list
jenkins create . --override

Alternately, $JENKINS_HOST and $JENKINS_PORT can be provided in lieu of the cached target Jenkins CI server

JENKINS_HOST=localhost JENKINS_PORT=3001 jenkins list

Developer Instructions

The dependencies for the gem and for developing the gem are managed by Bundler.

gem install bundler
git clone http://github.com/cowboyd/jenkins.rb.git
bundle install

The test suites expects Jenkins to speak English. If you are not using an English locale prepare the terminal session running the test suite with:

export LC_ALL=en_US.UTF-8

The test suite is run with:

rake

This launches a Jenkins server, runs cucumber features, and kills the Jenkins server.

Alternately, manually launch the Jenkins server, run features and close the Jenkins server:

rake jenkins:server:test
rake cucumber:ok
rake jenkins:server:killtest
