Demo Cookbook

This Chef cookbook is a code sample from Issue 7.6 of Practicing Ruby. It installs Ruby 2.0, updates RubyGems to the latest version, and then installs the Bundler gem. It makes use of the ruby_build cookbook to do its heavy lifting.

Requirements

To use this cookbook, you need the following software:

• VirtualBox - Version 4.2 or higher
• Vagrant - Version 1.3.4 or higher
• vagrant-omnibus - installable via vagrant plugin install vagrant-omnibus
• Berkshelf - installable via bundle install

When you provision a VM using this cookbook, Chef will be installed for you via vagrant-omnibus, and if necessary an Ubuntu Linux base system image will be downloaded automatically. See the project's Vagrantfile for exact versions used.

Provisioning

Run the following two commands inside the cookbook to create a vagrant box and boot it up:

$ bundle exec berks install --path vendor/cookbooks
$ vagrant up --provision

In case the VM is already up, you can always run Chef again with:

$ bundle exec berks install --path vendor/cookbooks
$ vagrant provision

To SSH into the running VM:

$ vagrant ssh

You can verify the Ruby, RubyGems, and Bundler versions with the following commands:

$ ruby -v
$ gem -v
$ bundle -v

Last but not least, here is how to stop and destroy the VM when you no longer need it or when you want to start from scratch:

$ vagrant destroy -f
