By default bookkeeper headless service name is configured as [CLUSTER_NAME]-bookie-headless.
bookkeeper-bookie-headless ClusterIP None <none> 3181/TCP 4d15h
But we can configure the headless service name as follows:
helm install bookkeeper pravega/bookkeeper --set headlessSvcNameSuffix="headless"
After installation services can be listed using kubectl get svc command.
bookkeeper-headless ClusterIP None <none> 3181/TCP 4d15h
