chef-solo cookbooks for Ruby on Rails app

Set of roles and recipes for bootstrapping typical Ruby on Rails website. It uses nginx, unicorn and Percona. Has been tested with Ubuntu 12.10 (see Vagrantfile).

Requirements

1. You should be able to login as root to the target system.
2. Ruby 1.9.3 (will be installed automatically)

Configuration

All configuration stored in JSON files (one file per node). See http://matschaffer.github.io/knife-solo/ for details.

user

chef will create user (node[:application][:user][:name]) which will be an owner of app directory. unicorn also will be started by this user. This user should be used when deploying with capistrano.

redirect_urls

Set if you need to permanently redirect users from some subdomains to the main domain. The most common case if you need to redirect them from www.exacmple.com to example.com.

http_auth

This option can be used if you need to protect the website using HTTP Basic Auth. Simply remove it if you don't need it.

Passwordless deploys

If you'd like to do passwordless deploys (using SSH public keys), you may wish to add public keys of users which should have such ability to the data_bags/authorized_keys/ folder. These keys should be also added to the node configuration under the node[:authorization][:ssh].
