title: Find docker file path according to container id
body: <p>I want to download Docker container logs to my local. I know my container's container id. </p>
  
  <p>Now, I use <code>df -h</code> to find the docker file path. Like this <code>/data/docker/overlay2/ea3e1ad0ccdee0e41d83722dfc6bf913250abd57918fecabd1067736b3e44305/merged</code>. But I have multiple containers, it is difficult to know my container's file path.</p>
  
  <p>How can I know <code>ea3e1ad0ccdee0e41d83722dfc6bf913250abd57918fecabd1067736b3e44305</code> according to my container id.</p>
