devops-israel / chef-rails_application

A Chef cookbook that installs a Rails application and can be fully customized using attributes.

rails_application Cookbook

This cookbooks installs the server-side Rails application. Unlike the official OpsCode cookbooks, this cookbook has all of the possible tweaks externalized in the form of attributes - it was intended that this cookbook is used by a wrapper cookbook that provides the attributes which configure the rails application per the requirements of the actual application.

This cookbook replaces the unicorn process supervisor to be upstart instead of runit, it means that it will work on Ubuntu systems, later versions might allow customizing the process supervisor as well.

Requirements

Tested on Ubuntu 12.04 and depends on several OpsCode official cookbooks that actually do the majority of the work.

packages

This cookbook depends on several OpsCode cookbooks, namely -

• git
• ruby
• nginx
• unicorn
• application
• application_ruby
• application_nginx

for the rails_application::database_credentials cookbook, you also need -

• database

Several of the above required minor modifications, all of these have pull requests and tickets with OpsCode, but until these get accepted, forks that include the modifications are available here -

application_ruby cookbook (no pull requests at this time)
