Customize kafka config

[jackchuong]

Hi all,
I'm using Strimzi Kafka operator for creating and managing Kafka on K8S, here my yaml

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: kafka-cluster1
  namespace: kafka
spec:
  kafka:
    version: 3.4.0
    replicas: 3
    listeners:
      - name: plain
        port: 9092
        type: internal
        tls: false
      - name: tls
        port: 9093
        type: internal
        tls: true
    config:
      num.partitions: 3
      offsets.topic.replication.factor: 3
      transaction.state.log.replication.factor: 3
      transaction.state.log.min.isr: 2
      default.replication.factor: 3
      min.insync.replicas: 2
      inter.broker.protocol.version: "3.4.0"
      log.cleanup.policy: compact,delete
    storage:
      type: jbod
      volumes:
      - id: 0
        type: persistent-claim
        class: nfs-idcnas002
        size: 10Gi
        deleteClaim: true
    resources:
      requests:
        memory: 1Gi
        cpu: "0.5"
      limits:
        memory: 4Gi
        cpu: "2"
  zookeeper:
    replicas: 3
    storage:
      type: persistent-claim
      class: nfs-idcnas002
      size: 10Gi
      deleteClaim: true
  entityOperator:
    topicOperator: {}
    userOperator: {}

How can I customize kafka configuration as below ?

echo producer.override.linger.ms=50 >> /opt/kafka/config/kraft/server.properties
echo producer.override.batch.size=40000 >> /opt/kafka/config/kraft/server.properties

The above options you are mentioning are part of the Kafka producer configuration. They have no relation with the Kafka broker configuration. You have to set them on your producer application, and they are just linger.ms and batch.size without that producer.override prefix.
