title: How to check if the docker image has all the files?
body: <p>Is there a way to check if the docker image has all of the files that the Dockerfile copies over and to understand if the image is built as configured in the Dockerfile?  My situation is that the image is built successfully, however when I try running it, docker complains that it cant find some file or other and the container fails to run, so I cant exec on it.  </p>
  
  <p>Doing docker inspect is not helping since it does not report on the files in the image.  Is there some method?</p>
