title: is possible to link a DNS name to another DNS name in docker?
body: <p>I'm kind of new on docker. I want to resolve DNS name into something define by the user. I mean, I have a service in docker which requires another service located in 'myEndpoint'. I want to configure that when the service asked to 'myEndpoint' returns an IP/FQN I decide, either in the containers or outside. </p>
  
  <p>How I can do this?</p>
