Poor Man's Deploy

• Start a Sinatra server on port 4000
• GET / to that server triggers a git pull and mod_rails restart
• Hit port 4000 locally after pushing

Why?

We wanted a really, really simple way to deploy Hurl during the 2009 Rails Rumble.

config.ru

require 'rubygems'
require 'deployr'
require 'thin'

Rack::Handler::Thin.run Deployr.new, :Port => 4000

deployr.rb

require 'sinatra/base'

class Deployr < Sinatra::Base
  get '/' do
    update_hurl
    "ok"
  end

  def update_hurl
    return if @running
    @running = true
    Thread.new do
      system "cd /www/hurl/current && git pull origin master && touch tmp/restart.txt"
      @running = false
    end
  end
end

Rakefile

task :default => :deploy

desc "Sync changes and deploy the app!"
task :deploy do
  `git pull origin master && git push origin master`
  `curl -s http://hurl.r09.railsrumble.com:4000/ &> /dev/null`
end
