Strimzi 操作员 Kafka 集群 ACL 未启用类型：简单

Question

We know to enable Kafka ACL property authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer to be added in server.properties but how to enable that if Kafka cluster is running by Strimzi operator?

From Strimzi documents I have come to know in order to enable authorization, need to enable below code for kind: Kafka under spec:

listeners:
      tls:
        authentication:
         type: tls 

Full code @ kafka-zookeeper-apps-tls-enabled.yml

Also the below code for kind: KafkaUser

authentication:
    type: tls
  authorization:
    type: simple

Full code@ example-consumer-deny-deployment-authentication-TLS-alias-SSL.yml

In above example-consumer-deny-deployment-authentication-TLS-alias-SSL.yml code although ACL type: deny am still able to consume messages.

Problem is even with the above code I see in kafka my-cluster-kafka-0 pod environment variable KAFKA_AUTHORIZATION_TYPE=simple is absent even the authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer is absent in server.properties

Note: No Warnings/Errors in log of strimzi-cluster-operator pod while deploying above code.

I am working on Strimzi for 1st time so please help me enabling ACL's.

Your Kafka custom resource doesn't enable You need to add the `authorization section.

    listeners:
      tls:
        authentication:
          type: tls
      external:
        type: route
        authentication:
          type: tls
    authorization:
      type: simple
      superUsers:
        - CN=my-user

You can read more about it in the documentation: https://strimzi.io/docs/latest/full.html#assembly-kafka-authentication-and-authorization-deployment-configuration-kafka
