title: Running multiple python main files off Docker image
body: <p>I have created a Docker image with dockerfile where the Entrypoint is as follows:</p>
  <pre><code>ENTRYPOINT [&quot;conda&quot;, &quot;run&quot;, &quot;--no-capture-output&quot;, &quot;-n&quot;, &quot;myproject&quot;, &quot;python&quot;, &quot;./myprojectmain.py&quot;, &quot;--config&quot;, &quot;./config.py&quot;]
  </code></pre>
  <p>When I run I use the command:</p>
  <pre><code>docker run myproject
  </code></pre>
  <p>all is fine it seems.
  However I have a secondary .py file in the root of the project called setup.py. The purpose of this file is to update some of the config and json files after getting some input from the user.</p>
  <p>Is there a way to run this secondary file (setup.py) or do I need to create a whole new image (which seems ridiculous).</p>
  <p>Thanks</p>
