William

Create deployment scripts with William's easy DSL to interact with your server via SSH.

Installation

gem install william

Usage

  • First, create a Willfile inside your project's directory :
$remotes = ["user@host.com"]

def deploy
  puts "I'm deploying!!!"
  cd "/home/user/myapp" do
    run "git pull origin master"
    run "bundle install --without development"
    run "rake db:migrate RAILS_ENV='production'"
    run "touch ./tmp/restart.txt"
  end
end

def test
  puts "I'm testing!!!"
  local "rake spec"
  local "rake jasmine"
end
  • Run the your script's deploy task with will deploy , or just the test task with (you guessed it) will test.

TODO

  • for now, every executed command requires a new SSH authentication. In the future i'd like to retain the connexion state to remove the need to re-enter the password for every single command (when my public key is not in the remote server's .ssh/authorized_keys).
  • write some tests!
  • make it possible to do some useful stuff with the return value of commands (maybe return an object, with .failed and .return_code, like Fabric does).
  • document the code
  • add abort, warn, sudo, prompt, put, get, reboot, prefix and lcd commands

Inspiration

William is my attempt at doing a Ruby version of Fabric.
