Using Ruby 2.0 on Amazon OpsWorks

Question

I'd like to use Ruby 2.0 on Amazon OpsWorks, so I'm trying the following:

• Choose custom cookbooks and set them to my fork of https://github.com/aws/opsworks-cookbooks
• Update all version numbers here https://github.com/aws/opsworks-cookbooks/blob/master/ruby/attributes/ruby.rb to 2.0 values.

This doesn't seem to have any effect, though.

• Do custom cookbooks override their built in counterparts?
• Does OpsWorks use the Ruby recipe from the cookbook for basic Ruby setup?
• The same question applies to Nginx too - can I control versions and settings by changing my fork for the cookbooks?

Answer 1

Opsworks already has support for Ruby 2.0, it's just not exposed through the UI. However, you can easily enable it by simply passing in the following custom JSON

{
  "opsworks" : {
    "ruby_version" : "2.0.0"
  }
}

That's it! No need to install any custom packages or anything.

Answer 2

OpsWorks now fully supports Ruby 2.0, in Layer settings you can specify the version of Rails, Bundler and Rubygems.
