Service exposition with ListenerClasses

Apache NiFi offers a web UI and an API. The Operator deploys a service called <name> (where <name> is the name of the NifiCluster) through which NiFi can be reached.

This service can have either the cluster-internal or external-unstable type. external-stable is not supported for NiFi at the moment. Read more about the types in the service exposition documentation at platform level.

This is how the listener class is configured:

spec:
  clusterConfig:
    listenerClass: cluster-internal  (1)
1 The default cluster-internal setting.
