title: Multiple Docker containers, same image, different config
body: <p>I'm totally new to Docker so I appreciate your patience.</p>
  
  <p>I'm looking for a way to deploy multiple containers with the same image, however I need to pass in a different config (file) to each? </p>
  
  <p>Right now, my understanding is that once you build an image, that's what gets deployed, but the problem for me is that I don't see the point in building multiple images of the same application when it's only the config that is different between the containers.</p>
  
  <p>If this is the norm, then I'll have to deal with it however if there's another way then please put me out of my misery! :)</p>
  
  <p>Thanks!</p>
