====== Basic Rack Application ======

[[https://www.gandi.net/hosting/simple?language=ruby&db=mysql|{{:fr:tutorials:simple:ruby.png?nolink|}}]]

To create a basic [[http://rack.github.io/ | Rack]] application, all you need is a file named `config.ru`.

<code>
# config.ru

run lambda { |env|
  status = 200
  header = {'Content-Type'=>'text/plain'}
  body = StringIO.new("Hello Rack World!")
  return [status, header, body]
}
</code>

You can then add files to your git tree and deploy it on your instance by following these instructions:
