title: How to access generated files inside Docker image
body: <p>So basically I have a python script that will write to a file once it is done running. How do I access this file? My end goal is to run the docker image on jenkins and then read the xml file that the python script generates.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>FROM python:3
  
  ADD WebChecker.py /
  
  ADD requirements.txt /
  
  ADD sites.csv /
  
  RUN pip install -r requirements.txt
  
  CMD [ "python", "./WebChecker.py" ]</code></pre>
  </div>
  </div>
  </p>
  
  <p>That is my Dockerfile. I have a print("Finished") in there and it is printing so that means everything is working fine. It's just now I need to see my output.xml file.</p>
