Lagom with Cassandra on Kubernetes service discovery in a different namespace

Akka Libraries

I can’t figure out (the first steps in configuring kubernetes) what is needed for the configuration.
I have:

  1. kubernes cluster
  2. deployed application in ping-pong-cluster namespace
  3. cassandra cluster cluster1-dc1-all-pods-service deploed with cass-operator in cass-operator namespace
  4. configs
    lagom.akka.discovery.service-name-mappings.cas_native.lookup=_native._tcp.cluster1-dc1-service.cass-operator.svc.cluster.local 
    akka.discovery.method=kubernetes-api

From Debugging DNS Resolution

kubectl exec -n ping-pong-cluster dnsutils -- nslookup _native._tcp.cluster1-dc1-service.cass-operator.svc.cluster.local

found:

Name:	_native._tcp.cluster1-dc1-service.cass-operator.svc.cluster.local
Address: 10.244.2.6

But one problem:

[2021-04-01 19:09:23,550] [INFO] [akka.discovery.kubernetes.KubernetesApiServiceDiscovery] [] [application-akka.actor.default-dispatcher-12] - Querying for pods with label selector: [app=cluster1-dc1-service.cass-operator.svc.cluster.local]. Namespace: [ping-pong-cluster]. Port: [Some(native)] MDC: {akkaAddress=akka://application@10.244.2.68:25520, sourceThread=application-lagom.persistence.dispatcher-34, akkaSource=KubernetesApiServiceDiscovery(akka://application), sourceActorSystem=application, akkaTimestamp=19:09:23.550UTC}

as I understand it the lookup takes place in a different namespace
