title: Merge two docker images
body: <p>I'm hoping to use docker to set up some bioinformatic analysis.</p>
  
  <p>I have found two docker images that I would like to use:</p>
  
  <ol>
  <li>jupyter/datascience-notebook</li>
  <li>bioconductor/devel_base</li>
  </ol>
  
  <p>I have been successful in running each of these images independently, however I don't know how to merge them together.</p>
  
  <p>Is merging two docker containers possible? Or do you start with one, and then manually install the features of the other?</p>
