DMaaP will also now leverage the Strimzi Apache Kafka project for the deployment of Kafka, including some of the relevant Strimzi offerings. This will replace the existing custom Confluent Kafka and Zookeeper images used by DMaaP Message Router. This will also add a new dependency for any existing Kafka Native clients within ONAP (CPS, HV-VES, CDS, etc), including DMaaP MR. |
Strimzi uses Kubernetes Operators to deploy it's Custom Resource Definitions (CRDs) to the k8s cluster.
The Cluster Operator manages the deployment of the Kafka Cluster and the Entity Operator (User and Topic Operators) which are used to manage Topic creation and Topic access control via the KafkaUser CRD.
In addition, DMaaP will offer the Strimzi Kafka Bridge which becomes an alternative ResT based messaging interface towards the Kafka Cluster:
