+ Create a Strimzi KafkaUser.
+ Usage:
+ include "common.kafkauser" .
+
+ Strimzi kafka provides cluster access via its custom resource definition KafkaUser
+ which is deployed using its User Operator component.
+ See more info here - https://github.com/strimzi/strimzi-kafka-operator/blob/main/helm-charts/helm3/strimzi-kafka-operator/crds/044-Crd-kafkauser.yaml
+ This allows fine grained access control per user towards the kafka cluster.
+ See more info here - https://strimzi.io/docs/operators/latest/configuring.html#proc-configuring-kafka-user-str
+
+ The kafka user definition is defined as part of .Values per component.
+ For general use by OOM components, the following list of acl types should suffice:
+ type: group (Used by the client app to be added to a particular kafka consumer group)
+ type: topic (1 or more kafka topics that the client needs to access. Commonly [Read,Write])
+
+ Note: The template will use the following default values.
+
+ spec.authentication.type: scram-sha-512 (dictated by the available broker listeners on the kafka cluster)
+ spec.authorization.type: simple (Only type supported by strimzi at present)
+ spec.authorization.acls.resource.patternType: literal
+
+ Example:
+
+ kafkaUser:
+ acls:
+ - name: sdc (mandatory)
+ suffix: mysuffix (optional. Will be appended (with a hyphen) to the "name" entry. ie "sdc-mysuffix")
+ type: group (mandatory. Type "group" is used by the client as it's kafka consumer group)
+ operations: [Read] (mandatory. List of at least 1)
+ - name: SDC-DISTR
+ type: topic
+ patternType: prefix (optional. In this example, the user will be provided Read and Write access to all topics named "SDC-DISTR*")
+ operations: [Read, Write]
