Simple Rails deployment and configuration management. 15 minute deploys of Rails 2, 3, or 4 apps.


Moonshine is Rails deployment and configuration management done right.

By leveraging capistrano and puppet, moonshine allows you have a working application server in 15 minutes, and be able to sanely manage it's configuration from the comfort of your version control of choice.

To get started, check out our tutorial. It covers configuring and deploying your application for the first time with Moonshine.

Once you're a bit more comfortable with Moonshine, you'll find our documentation on the wiki to be helpful!


  • A server running Ubuntu 8.10 or 10.04 LTS (Want to see your favorite platform supported? Fork Moonshine on GitHub!)
  • A Rails 2.3 or Rails 3 app. Rails 4 is supported with the plugger gem.
  • A user on this server that can:
    • Execute commands via sudo
    • Access your application's source code repository


It's also pretty simple!

Rails 2

$ script/plugin install git://
$ script/generate moonshine

Rails 3

$ script/rails plugin install git://
$ script/rails generate moonshine

Rails 4

Add gem 'plugger' to your Gemfile and bundle install, then:

$ plugger install git://
$ script/rails generate moonshine

Running Tests

It's easy enough:

$ gem install shadow_puppet isolate-scenarios
$ rake spec

isolate-scenarios is used to test against multiple versions of Rails. To run all scenarios at once:

$ isolate-scenarios rake spec

Passenger Enterprise Support

We've added support for Passenger Enterprise Edition! In order to install it, you need to make a few changes to moonshine.yml. Since you have to download the gem from Phusion, you now need to tell us where it is. You also need to put your license file in app/manifests/templates and call it passenger-enterprise-license so we can put it in the right place during install.

This is what a passenger enterprise block in moonshine.yml should look like (in addition to your usual Passenger settings):

  :version: 4.0.5
  :enterprise: true
  :gemfile: vendor/gems/passenger-enterprise-server-4.0.5.gem
  :rolling_restarts: true

A Word on Rails 4

We've been torturing ourselves trying to turn Moonshine into a gem ever since it was announced that Rails 4 was dropping support for plugins. Moonshine is... different... and we think it actually makes sense as a plugin. So, instead of turning Moonshine, and the dozens of Moonshine plugins we've written, into a gem, we decided to add plugin support back to Rails 4! That's where plugger comes in. Just add it to your Gemfile and bundle install and voila, plugins are back!

Something went wrong with that request. Please try again.
