Kafka Docker image. It expects a comma delimited list of ZooKeeper servers via the ZOOKEEPER_SERVERS environment variable, an optional root path within ZooKeeper were to store it's state via ZOOKEEPER_ROOT (it defaults to /kafka), and an optional hostname for the broker to adversize to clients via ADVERTISED_HOST_NAME (it defaults to the output of hostname -f).

It can be executed in Kuebernetes using a replication controller using a config like:

apiVersion: v1
kind: Service
metadata:
  name: kafka
spec:
  clusterIP: None
  ports:
    - name: kafka
      port: 9092
    - name: jmx
      port: 7203
  selector:
    app: kafka
