I am trying to deploy Rabbitmq cluster on Kubernetes cluster with Kubernetes deployment kind rather then StatefulSet.

I am getting the below error.

Blockquote ERROR: epmd error for host rabbitmq-c9f555bf6-xfkd9.rabbitmq.test-rabbitmq.svc.cluster.local: nxdomain (non-existing domain)

What is wrong with this?
