Postgres-operator: RBAC Issue : configmaps "postgres-operator" is forbidden (GKE)

[eaydogan]

Hi,
I have problem with rbac.

kubectl create namespace test
kubectl create -f manifests/configmap.yaml -n test
kubectl create -f manifests/postgres-operator.yaml -n test

kubectl get pods -n test

NAME READY STATUS RESTARTS AGE
postgres-operator-686dfdc7fc-k42j2 0/1 CrashLoopBackOff 4 3m

kubectl logs postgres-operator-686dfdc7fc-k42j2 -n test

panic: configmaps "postgres-operator" is forbidden: User "system:serviceaccount:test:operator" cannot get configmaps in the namespace "test"

goroutine 1 [running]:

After few additional steps... postgres-operator is now running...

Current settings works without error when use GKE but dedicated clusters you need additional steps.

1) role and role binding
2) cluster role and cluster role binding
3) pvc

I can document steps and send pull request if this help someone.

Seems to be related to #274. Closing this issue. If you can still recall your steps, feel free to add a PR that explains running the operator on GKE.
