You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: jenkins.rb
    path of file: ./repos/gitlabhq/qa/qa/service/docker_run
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module QA
  module Service
    module DockerRun
      class Jenkins < Base
        include Mixins::ThirdPartyDocker

        attr_reader :port

        def initialize
          @image = "#{third_party_repository}/jenkins:latest"
          
    
        def register!
          authenticate_third_party

          command = <<~CMD.tr("\n", ' ')
            docker run -d --rm
            --network #{network}
            --hostname #{host_name}
            --name #{@name}

          CMD

          shell(command, mask_secrets: [password])
