# NOTE(mnaser): When a StatefulSet is deployed, it creates the pods one
#               by one, which means the `kubectl wait` can race if it
#               is ran before the other pods are created.  We instead
#               check for all the StatefulSets here manually instead
#               and then use the second check below to do a "confirmation"
