  -First, create an OpenShift service account which is used by the crunchy-watch
  -container to perform the failover. Also, set policies that allow the
  -service account the ability to edit resources within the OpenShift and
  -default projects.

positive.code: 
  To test it out, delete the primary pod and view the watch pod log:

negative.code: A final test is to see if the old replica is now a fully functioning

  ....
  
  The above command still works because the watch container has
