rbenv cookbook

Installs and manages your versions of Ruby and Gems in Chef with rbenv and ruby_build

• rbenv
• ruby_build

Requirements

• Chef 10
• Centos / Redhat / Fedora / Ubuntu / Debian
• Ruby >= 1.9

Usage

Add a dependency on rbenv to your cookbook's metadata.rb

depends 'rbenv'

Installing rbenv and ruby_build

To install rbenv and ruby_build; Include each recipe in one of your cookbook's recipes

include_recipe "rbenv::default"
include_recipe "rbenv::ruby_build"

Installing rbenv-vars

To install rbenv-vars; Include this recipe in one of your cookbook's recipes

include_recipe "rbenv::rbenv_vars"

Installing a Ruby

And now to install a Ruby use the rbenv_ruby LWRP

rbenv_ruby "1.9.3-p194"

Installing Gems for rbenv managed Rubies

If you'd like a specific Ruby installed by rbenv to include a Gem, say bundler, use the rbenv_gem LWRP

rbenv_gem "bundler" do
  ruby_version "1.9.3-p194"
end

Be sure to include a value for the ruby_version attribute so the gem is installed for the correct Ruby
