Hi. I have question.
I need to add init-container to couchbase pods. I`m using couchbase-operator.

cluster:
  servers:
    default:
      pod:
        spec:
          initContainers:
            - name: init-myservice
              image: registry.access.redhat.com/ubi8/ubi:latest
              command: ['sh', '-c', 'echo waiting for myservice; sleep 2; done;']

Ive tried add to section, but i dont see init container in cluster pods :confused:
Can u help me with that?
