title: How to add a private registry for image lookups in openshift
body: <p>I have a private registry at the url <code>registry.lab.example.com</code> where I can push images to from my master node in ocp cluster. When I go about launching a new app referring an image from this private registry, the lookup fails with a error message that the image is not found. </p>
  
  <pre><code>oc new-app --docker-image=registry.lab.example.com/openshift/nginx
  </code></pre>
  
  <p>My private registry is not even polled to look for the images and that'y why the deployment fails. Is there a way I can add this private registry in the list of <strong>to be searched repositories</strong> when docker tries to find an image?</p>
