Kubernetes cluster domain name not cluster.local

We would like to try the Kafka Replicator component on a Kubernetes-based Confluent Platform.

Our Kubernetes cluster’s domain name is not default one, i.e. cluster.local, but let’s say <something_else>.local.

As a result, when deploying the Confluent Platform, the Zookeeper servers fail to run, each one trying to connect to the service of each other Zookeeper server in the <namespace>.svc.cluster.local domain instead of the <namespace>.svc.<something_else>.local one.

I unsuccessfully tried to override the default domain name when deploying the Confluent Operator using helm with the --set k8sClusterDomain=<something_else>.local option.

Is there any way to fix this error?

Thank you
