Convert Chef Ruby DSL Roles to JSON

chef_rb_roles_to_json.rb

require 'chef'

# Update path to reflect    where your roles are stored
ROLE_DIR = "/Users/bmurtagh/chef-repo/roles"

Dir.glob(File.join(ROLE_DIR, '*.rb')) do |rb_file|
  role = Chef::Role.new
  role.from_file(rb_file)
  json_file = rb_file.sub(/\.rb$/,'.json') 
  File.open(json_file, 'w'){|f| f.write(JSON.pretty_generate(role))}
end

This little script is getting some use 4 years later @bmurtagh. Thanks!

I expanded on it a bit further as well:
