title: Getting Docker private registry URL
body: <p>I have been trying to deploy [to a Kubernetes cluster] a Docker image that is present in my private Docker registry. So, my private registry in Docker looks like this:</p>
  <pre><code>summer/my-app:version1.1
  </code></pre>
  <p>In order to deploy the app to a Kubernetes cluster, I need to specify the image name in <code>my-app-deployment.yml</code> file. This image name however requires a complete path to the registry. Unlike from official Docker images which uses the format like this: <code>registry.hub.docker.com/&lt;user&gt;/&lt;image&gt;</code>, it did not work in my case and yielded an error <code>ImagePullBackOff</code> during deployment.</p>
  <p>Is there a different format to this, when deploying from a private Docker registry?</p>
