title: Openshift: Simplest way to create an ImageStream from a github project
body: <p><br/>
  I have a project which is available on github. I can actually add a new Java Enterprise app based on this project and have the ImageStream available:</p>
  
  <pre><code>$ oc new-app https://github.com/ocpuser/ocpdemos.git --image-stream="openshift/wildfly:latest"
  
  $ oc get is
  NAME       DOCKER REPO                          TAGS      UPDATED
  javaeedemo   172.30.1.1:5000/myproject/javaeedemo
  </code></pre>
  
  <p>However, what is the simplest way to create just the ImageStream (without adding a new app)? My purpose is to add the ImageStream to the internal repository so that I can use it in Openshift Operators requiring it.
  Thanks</p>
