Acknowledgements

RVM in conjunction with Chef is shit.

Cookbook Requirements

• apt
• build-essential

Attributes

• default[:chef_ruby][:version] = "1.9.3-p194": string containing the ruby version you want to install.
• default[:chef_ruby][:rubygems][:version] = "1.8.25": string containing the rubygems version you want to install.

Recipes

• default: installs Ruby from source.

Usage

When setting up a system for the first time, Ohai will profile it and then store the ruby directory as /opt/chef/embedded/lib/ruby.
This attribute (normally referenced in cookbooks as languages[:ruby][:gems_dir]) does not get reset automatically when a new Ruby is
installed. The default recipe tells Ohai to reload its attributes. Adding this block to any recipe that uses the attribute languages[:ruby][:gems_dir];
then, whenever Ohai reloads its attributes, your cookbook will also reload its attributes.

ruby_block "reload_ruby" do
  block do
    node.load_attribute_by_short_filename('<filename of attributes, eg default>', '<name of cookbook that contains the attributes>')
  end

  action :nothing
  subscribes :create, "ohai[reload]", :immediately
end
