# 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"
