• It seems the Cruise Contorl deployment doesn't have "app.kubernetes.io/name=strimzi" label
• The following command are described in the document(1). However, "No resources found" message was output.

  3. Verify that Cruise Control was successfully deployed:
      oc get deployments -l app.kubernetes.io/name=strimzi
      ==> No resources found in exampleproject namespace.
  

• The Cruise Control deployment has the following labels, so "oc get deployments -l app.kubernetes.io/name=cruise-control" command may be appropriate.

  ...
      labels:
        app.kubernetes.io/instance: my-cluster
        app.kubernetes.io/managed-by: strimzi-cluster-operator
        app.kubernetes.io/name: cruise-control
        app.kubernetes.io/part-of: strimzi-my-cluster
        strimzi.io/cluster: my-cluster
        strimzi.io/kind: Kafka
        strimzi.io/name: my-cluster-cruise-control
