Kafka can be accessed by consumers via port 9092 on the following DNS name from within your cluster:

    kafka.default.svc.cluster.local

Each Kafka broker can be accessed by producers via port 9092 on the following DNS name(s) from within your cluster:

    kafka-0.kafka-headless.default.svc.cluster.local:9092

To create a pod that you can use as a Kafka client run the following commands:

            --broker-list kafka-0.kafka-headless.default.svc.cluster.local:9092 \
            --topic test
