[bitnami/kafka] How can I set the "advertised.listener" for each broker with server.config?

[midi79]

Which chart: Kafka

Is your feature request related to a problem? Please describe. I am trying to install the kafka in the Kubernetes cluster which has three brokers. And I'd like to add to "advertised.listener" for each broker's "server.config" file. However, I cannot add that config when the kafka starts. I added "Value.yaml" which has options for "advertised.listener", but it didn't work. When I added the "advertised.listener=XXXXXX" in the config option, the brokers didn't run. And I tried to add the "advertisedListeners:" option, but it also didn't work. I saw the additional options generated dynamically on the "setup.sh" file when I install or upgrade helm chart. BUT, the "setup.sh" script didn't execute when the kafka broker started. How can I add the advertised.listener option for each broker?

Describe the solution you'd like The "setup.sh" script have to run when the broker start.

Describe alternatives you've considered When I install or upgrade the helm chart, the helm should make "server.config" file dynamically with "advertised.listener=XXXXXX"

Additional context Add any other context or screenshots about the feature request here.

Hi @midi79!

Could you share the parameters you are setting on the values.yaml file? Thanks!

[midi79]

@pablogalegoc I really appreciate your help! Here is our "value.yaml" file. Its name was modified because yaml file shouldn't upload directly. Please check it.

@midi79 sorry for the late response, have you tried setting the advertisedListeners like this:

advertisedListeners:
  - "INTERNAL://test:9093"
  - "CLIENT://test:9092"

I can see them being picked by the kafka pod:

❯ kubectl describe pod/kafka-0 | grep KAFKA_CFG_ADVERTISED_LISTENERS
      KAFKA_CFG_ADVERTISED_LISTENERS:                      INTERNAL://test:9093,CLIENT://test:9092

listeners: []
advertisedListeners: []
listenerSecurityProtocolMap: ""
allowPlaintextListener: true
interBrokerListenerName: INTERNAL

these below are my pods

kafka-0                         1/1     Running     0          4h32m
kafka-1                         1/1     Running     0          2m19s
kafka-2                         1/1     Running     0          3m7s
kafka-client                    1/1     Running     0          3d4h
zookeeper-0                     1/1     Running     0          2d1h
zookeeper-1                     1/1     Running     0          2d1h
zookeeper-2                     1/1     Running     0          2d1h

and these are my svc

kafka                ClusterIP   a.b.c.d    <none>        9092/TCP                     4h51m
