title: Is it possible to start a shell session in a running container (without ssh)
body: <p>I was naively expecting this command to run a bash shell in a running container : </p>
  
  <pre><code>docker run "id of running container" /bin/bash
  </code></pre>
  
  <p>it looks like it's not possible, I get the error : </p>
  
  <pre><code>2013/07/27 20:00:24 Internal server error: 404 trying to fetch remote history for 27d757283842
  </code></pre>
  
  <p>So, if I want to run bash shell in a running container (ex. for diagnosis purposes)</p>
  
  <p>do I have to run an SSH server in it and loggin via ssh ?</p>
