title: How to push a docker image to a private repository
body: <p>I have a docker image tagged as <code>me/my-image</code>, and I have a private repo on the dockerhub named <code>me-private</code>.<br>
  When I push my <code>me/my-image</code>, I end up always hitting the public repo.</p>
  
  <p>What is the exact syntax to specifically push my image to my private repo? </p>
