Following on from KafkaUser in another namespace you will also need to sync the kafka-cluster-cluster-ca-cert too.

This is also straight forward and can be done with zero impact to existing services. The trick is to annotate the clusterCaCert generation with the necessary details

In your Kafka yaml add the following under kafka

reflector.v1.k8s.emberstack.com/reflection-allowed: "true"
reflector.v1.k8s.emberstack.com/reflection-allowed-namespaces: "fluent"

and create a secret to mirror it

apiVersion: v1                                                                                  
kind: Secret
name: kafka-cluster-cluster-ca-cert
namespace: fluent
reflector.v1.k8s.emberstack.com/reflects: "kafka/kafka-cluster-cluster-ca-cert"
type: …
