Scopes

Sometimes (very often, actually) you have to declare several resources with the same name and repetition of the same resource name over and over again makes code look messy and not DRY. Scope is the answer to the problem - in the defined scope you can omit resource name in declarations and the scope name will be used instead:

R.scope :frontend do
  config_map do
    add_application_label

    set BACKEND_URL: 'http://backend'
  end

  deployment do
    container do
      image V.frontend.image
    end

    environment do
      use_config_map
    end
  end
end

The code above will define ConfigMap with the name frontend, label application and value BACKEND_URL. It will also define a Deployment with the same name, that uses an image, defined in the values file and use environment variables, defined as values of the ConfigMap with the same name as a Deployment. Clear and DRY!
