title: Docker pull - force download
body: <p>Is there a possibility to force pull of docker image?</p>
  
  <p>I have redeployed docker image to another repository, but when I invoke</p>
  
  <pre><code>docker pull anotherrepo:port/my/image
  </code></pre>
  
  <p>nothing gets downloaded, instead I get info:</p>
  
  <pre><code>Digest: sha256:somehash
  </code></pre>
  
  <p>and that image is up to date.</p>
  
  <p>docker rm/rmi doesn't work because the image is downloaded from originalrepo:port/my/image and I don't want to stop/delete it onyl for test purposes.</p>
  
  <p>Is there possible to force pull to check if the image is correctly pushed?</p>
