title: Docker container not starting
body: <p>I'm trying to run <a href="http://docs.docker.io/en/latest/examples/python_web_app/" rel="noreferrer">this docker example</a>. Yet it appears that I can't start my docker container.</p>
  
  <pre><code>sudo docker stop aff28c5dab3f
  sudo docker start aff28c5dab3f
  sudo docker ps
  ID                  IMAGE               COMMAND             CREATED             STATUS              PORTS
  
  sudo docker ps -a
  ID                  IMAGE                     COMMAND                CREATED             STATUS              PORTS

  </code></pre>
  
  <p>and when I try to run 
  <code>sudo docker attach aff28c5dab36</code>, I see <code>Impossible to attach to a stopped container, start it first</code></p>
