Chapter 21. KafkaAuthorizationSimple schema reference


Used in: KafkaClusterSpec

Full list of KafkaAuthorizationSimple schema properties

Configures the Kafka custom resource to use simple authorization and define Access Control Lists (ACLs).

ACLs allow you to define which users have access to which resources at a granular level.

Streams for Apache Kafka uses Kafka’s built-in authorization plugins as follows:

  • StandardAuthorizer for Kafka in KRaft mode
  • AclAuthorizer for ZooKeeper-based Kafka

Set the type property in the authorization section to the value simple, and configure a list of super users. Super users are always allowed without querying ACL rules.

Access rules are configured for the KafkaUser, as described in the ACLRule schema reference.

Example simple authorization configuration

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
  namespace: myproject
spec:
  kafka:
    # ...
    authorization:
      type: simple
      superUsers:
        - CN=user-1
        - user-2
        - CN=user-3
    # ...
Copy to Clipboard Toggle word wrap

Note

The super.user configuration option in the config property in Kafka.spec.kafka is ignored. Designate super users in the authorization property instead.
