cp-server arm64 fails when starts as single node on kubernetes

[denyskril]

Hi all,

when running kafka in kubernetes in single mode, kafka can't resolve kafka-0.kafka.confluent.svc But, there is no such problem with amd64

Version: 7.2.1

Couldn't resolve server kafka-0.kafka:9093

It's correctly resolving kafka-0.kafka.confluent.svc

It's not resolving the other, which seems like something you've set as the advertised listeners.

Are you using Helm or Operators?
