title: docker python custom module not found
body: <p>I am new to docker and trying to move one simple application to docker.
  Python standard modules I am able to import using "pip install". However, I have some custom python utility files that I would like to use.
  These files are in separate package "utils".</p>
  
  <p>In my main python file : <code>test.py</code>, I am doing</p>
  
  <pre><code>from utils import math.py, logger.py
  </code></pre>
  
  <p>This outside of docker works fine, but when running through docker gives me the error <code>"ImportError: No module named utils"</code>.</p>
  
  <p>My Dockerfile code:</p>
  
  <pre><code>FROM python:2.7.11
  ADD ./ test_project/
  WORKDIR test_project
  ENV PATH=$PATH:/test_project/utils
  ENV PYTHONPATH /test_project/utils
  
  CMD [ "python", "report/test.py"]
  </code></pre>
  
  <hr>
  
  <p>My directory structure:</p>
  
  <ul>
  <li><code>test_project</code>
  
  <ul>
  <li><code>report</code></li>
  <li><code>utils</code></li>
  </ul></li>
  </ul>
  
  <p>Any suggestions?</p>
