title: Dockerizing an existing Project
body: <p>I have a web based application using Play framework and Scala which I would like to Dockerize. Essentially, I would like to do the following:</p>
  
  <ol>
  <li>Create a docker file that would be my docker container for the play application</li>
  <li>Be able to pass in a configuration to this docker file so that I can build the docker image either for my local code base or pull from master branch</li>
  </ol>
  
  <p>Any suggestions on how do I get started?</p>
