Helm chart deployment is failing when my cluster-domain is not cluster.local

[mikeoleary]

I have used helm to install Confluent for Kubernetes, starting with the quickstart guide.

However, my cluster's DNS domain is not cluster.local. In my case it's a custom and compliant value that is in the format xxx.yyy.tenant.local

When I follow the steps to deploy via helm, my first Zookeeper pod in my StatefulSet constantly throws this error:

[ERROR] 2023-02-13 18:42:16,502 [ListenerHandler-zookeeper-0.zookeeper.confluent.svc.cluster.local:3888] org.apache.zookeeper.server.quorum.QuorumCnxManager acceptConnections - Exception while listening

Note, there is no service with a DNS name of "zookeeper.confluent.svc.cluster.local" which you can see is attempted in the logs. There is a service with DNS name of "zookeeper.confluent.svc.xxx.yyy.tenant.local" but that is not what is being accessed by this container.

How can I deploy Confluent for Kubernetes on a cluster with a custom cluster domain?

@mikeoleary You can use

spec:
  k8sClusterDomain: "xxx.yyy.tenant.local"

You can find more config in https://docs.confluent.io/operator/current/co-api.html#tag/Zookeeper
