Chapter 107. AclRule schema reference

Used in: KafkaUserAuthorizationSimple

Full list of AclRule schema properties

Configures access control rules for a KafkaUser when brokers are using simple authorization.

Example KafkaUser configuration with authorization

apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaUser
metadata:
  name: my-user
  labels:
    strimzi.io/cluster: my-cluster
spec:
  # ...
  authorization:
    type: simple
    acls:
      - resource:
          type: topic
          name: my-topic
          patternType: literal
        operations:
          - Read
          - Describe
      - resource:
          type: group
          name: my-group
          patternType: prefix
        operations:
          - Read

107.1. resource

Use the resource property to specify the resource that the rule applies to.

Simple authorization supports four resource types, which are specified in the type property:

  • Topics (topic)
  • Consumer Groups (group)
  • Clusters (cluster)
  • Transactional IDs (transactionalId)

For Topic, Group, and Transactional ID resources you can specify the name of the resource the rule applies to in the name property.

Cluster type resources have no name.

A name is specified as a literal or a prefix using the patternType property.

  • Literal names are taken exactly as they are specified in the name field.
  • Prefix names use the name value as a prefix and then apply the rule to all resources with names starting with that value.

When patternType is set as literal, you can set the name to * to indicate that the rule applies to all resources.

Example ACL rule that allows the user to read messages from all topics

    acls:
      - resource:
          type: topic
          name: "*"
          patternType: literal
        operations:
          - Read

107.2. type

The type of rule, which is to allow or deny (not currently supported) an operations.

The type field is optional. If type is unspecified, the ACL rule is treated as an allow rule.

107.3. operations

Specify a list of operations for the rule to allow or deny.

The following operations are supported:

  • Read
  • Write
  • Delete
  • Alter
  • Describe
  • All
  • IdempotentWrite
  • ClusterAction
  • Create
  • AlterConfigs
  • DescribeConfigs

Only certain operations work with each resource.

For more details about simple authorization, ACLs, and supported combinations of resources and operations, see Authorization and ACLs.

107.4. host

Use the host property to specify a remote host from which the rule is allowed or denied.

Use an asterisk (*) to allow or deny the operation from all hosts. The host field is optional. If host is unspecified, the * value is used by default.
