title: Disable docker md5sum with custom image
body: <p>I'm trying to modify a public image, and create a new image with my changes, but when I try to run a container with my new custom image it triggers a md5sum and deletes some of my changes, is it possible to disable the md5sum?</p>
  
  <p>Dockerfile:</p>
  
  <pre><code>FROM public-image:latest
  
  COPY . /dir
  
  RUN sh my-script.sh
  </code></pre>
  
  <p>my-script.sh is to copy files to different locations, one of the files I modify is constants.json but it triggers the md5sum and reverts the changes</p>
