Hudson
======

[Hudson CI](http://hudson-ci.org/) is a sweet continuous integration platform. Hudson.rb makes it easy to get started, add/remove Ruby jobs and slave nodes; either from a CLI or an API.

Install
=======

    gem install hudson

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

Example
=======

Hudson.rb is continuously tested using Hudson at [http://hudson.thefrontside.net/job/hudson.rb/](http://hudson.thefrontside.net/job/hudson.rb/).

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

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

Alternately use environment variables:

    $ HUDSON_HOST=hudson.thefrontside.net HUDSON_PORT=80 hudson list

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

    $ hudson list

Usage
=====

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

    Usage: hudson server [options]
      -p,  --port [3001]                         run hudson 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/.hudson/server]  use this directory to store server data

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

### Jobs

To list Jobs/Projects on a Hudson server:

    Usage: hudson list [options]

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

    Usage: hudson create PROJECT_PATH [options]
        --public-scm                     	  use public scm URL
        --template [ruby]                	  template of job steps (available: rails,rails3,ruby,rubygem)
        --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: hudson build

To remove a Job from a Hudson server:

    Usage: hudson remove PROJECT_PATH

### Slave nodes

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

    Usage: hudson nodes

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

    Usage: hudson add_node SLAVE_HOST
        --slave-port [22]          	  SSH port for Hudson 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 Hudson to use
        --name [NAME]              	  Name of slave node (default SLAVE_HOST)
        --slave-user [deploy]      	  SSH user for Hudson to connect to slave node

### Selecting a Hudson 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 Hudson CI server. For example:

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

Alternately, `$HUDSON_HOST` and `$HUDSON_PORT` can be provided in lieu of the cached target Hudson CI server

    HUDSON_HOST=localhost HUDSON_PORT=3001 hudson 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/hudson.rb.git
    bundle install

The test suite is run with:

    rake

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

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

    rake hudson:server:test
    rake cucumber:ok
    rake hudson:server:killtest
