title: Openshift: get access to openshift docker registry
body: <p>I've exposed my openshift registry:</p>
  
  <pre><code>$ oc get routes -n default
  NAME              HOST/PORT                                       PATH      SERVICES          PORT       TERMINATION   WILDCARD
  docker-registry   docker-registry-default.192.168.99.104.nip.io             docker-registry   5000-tcp                 None
  </code></pre>
  
  <p>Nevertheless, I'm trying to get access on that registry, but I've not been able to figure out what's wrong:</p>
  
  <pre><code>docker login -p ngRslZJYJ40WxBA6YQbE5nMDK1Gh-cSWgnJCKR4EJ2I docker-registry-default.192.168.99.104.nip.io -u unused
  </code></pre>
  
  <p>This command keeps stuck.</p>
