I am trying to produce to a kafka broker which is running inside the container launched by kubernetes. I am playing with KAFKA_ADVERTISED_LISTENERES and KAFKA_LISTERNERS.

I tried setting these two env variables KAFKA_ADVERTISED_LISTENERES = PLAINTEXT://<host-ip>:9092 and KAFKA_LISTERNERS = PLAINTEXT://0.0.0.0:9092 and ran using docker-compose. And I was able to produce from an application out of the host machine.

But setting these two env-variables in Kubernetes.yml file, I get No broker list available exception.

What am I missing here?

Update:

kafka-pod.yaml:
