Type of change
Description
Currently, the operator tries to get the advertised listener hostnames / ports for the controller nodes in KRaft mode and use them as an annotation. This is wrong as the controller nodes do not really have any advertised listeenrs. By coincidence, the
type: internal
listeners were geenrating the names so everything seemed to work. But when you try to deploy a Kafka cluster without such listener, it starts throwing NPEs.This PR cleans-up the handling to use the advertised hostnames / ports only for broker nodes for the annotations to fix this.
This should fix #9336.
