title: How do I expose ports on Heroku with a Dockerfile?
body: <p>I am trying to deploy a Docker image on Heroku and am trying to understand how to expose multiple ports.  Here is the Docker command that I am trying to run in the Heroku deploy:</p>
  
  <pre><code>docker run \
      -p 2222:22 \
      -p 33306:3306 \
      -p 27017:27017 \
      -p 28015:28015 \
      -p 29015:29015 \
      -p 8080:8080 \
      test/db-migration
  </code></pre>
