title: How to use existing Docker Volume in a Dockerfile
body: <p>I have created a new docker image. It creates a new folder <code>/hello</code>.
  When I run this image as a container, I can access the container by the <code>docker exec -it</code> .. bash command and when I perform <code>ls</code> I see the <code>/hello</code> folder.</p>
  
  <p>This <code>/hello</code> folder is also saved in a Docker volume container. 
  So I have linked the container with an existing Docker volume. So it's persistent.</p>
  
  <p>Now is my question: Is it possible to perform the following in a Dockerfile?</p>
  
  <p>A new image wants to use the same volume as the previous container, and copying the <code>/hello</code> file to its own container. </p>
  
  <p>Is this possible to perform in a docker file?</p>
