title: How to find which folder under overlay2 directory belong to which container?
body: <p>If I go to /var/lib/docker/overlay2 and do &quot;ls&quot;, then I get something like the following :</p>
  <p>0349eb19b8ac737f2a93e33f665ab26d95de636bf48de79e6e7d7cdd76c0cd78
  0c32910d4c394834e239f0c8f0776b36d87f7567b3120dff92ccd8d0f98577b0
  ...</p>
  <p>Now one or more of these folders belong to a container. I want to know which folder is used by which container ?</p>
  <p>Thanks</p>
