kafka not able to connect to zookeeper

When this command executed:
kubectl apply -f https://raw.githubusercontent.com/confluentinc/confluent-kubernetes-examples/master/quickstart-deploy/confluent-platform.yaml

Confluent operator log:
{"level":"ERROR","time":"2023-04-28T21:01:11.301Z","name":"kafka","caller":"log/log.go:35","msg":"apply failed","name":"kafka","namespace":"mnk","error":"no zk endpoint or service discovery configuration found for dependency"}
Logs from 4/28/2023, 1:57:35 AM

So kafka installation do not start and other components as well waiting for kafka.

Start with the referenced confluent-platform.yaml manifest and the Confluent operator log message about the missing ZooKeeper endpoint or service discovery configuration. Trace how Kafka's dependency is configured and verify the deployment with kubectl; done means Kafka starts successfully and dependent components no longer wait for it.
