title: Deploying with docker push is slow because there are many images
body: <p>I'm trying to deploy via docker. I'm using the following workflow:</p>
  
  <ol>
  <li>Build locally</li>
  <li>Push my image to docker hub</li>
  <li>On the server: pull the image </li>
  <li>On the server: start the image</li>
  </ol>
  
  <p>But docker push takes FOREVER. There are like 30 images, and it has to walk through each one and say "Image already exists". Is there any way to speed this up?</p>
  
  <p>Alternatively, should I be using a different process to deploy?</p>
