title: How to copy and rename a Docker container?
body: <p>I have a docker container that I want to use to partition client access to a database.  I'd like to be able to have one container per client. If I start multiple copies of the container they all have the same name, the only difference being the port the container is assigned to.</p>
  
  <p>How can I copy/rename the containers in such a way that I can differentiate the container without having to consult a lookup table that matches the assigned port to the client?</p>
