  # One of the benefits of docker-compose is the ability to easily spin up multiple apps like a test email server alongside Jenkins 
  # for testing email notifications from jenkins (later). And this will happen over 
  # the specicified virtual network created by docker-compose i.e. jenkins-net in this case
