title: Way to delete the images from Private Docker Registry
body: <p>I have a Private Docker Registry set up and i have pushed some images from other machine to this registry. 
  Its a V2 registry.
  I don't know a novel way to delete the images from repositories since these pushed images doesn't get listed in CLI for "docker images".</p>
  
  <p>Can anyone suggest me the proper way to delete those images from the disk?</p>
  
  <p>Appreciate a lot for answer.</p>
  
  <p>Thanks</p>
