    Metadata details:
    filename: role_binding.rb
    path of file: ./repos/gitlabhq/lib/gitlab/kubernetes
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

      def generate
        ::Kubeclient::Resource.new.tap do |resource|
          resource.metadata = metadata
          resource.roleRef  = role_ref
          resource.subjects = subjects
