Chapter 3. Deploying Kafka components using the Streams for Apache Kafka operator

Procedure

1. Navigate in the web console to the Operators > Installed Operators page and click Streams for Apache Kafka to display the operator details.

   From Provided APIs, you can create instances of Kafka components.

2. Click Create instance under Kafka to create a Kafka instance.

   By default, you’ll create a Kafka cluster called my-cluster:

   apiVersion: kafka.strimzi.io/v1beta2
   kind: Kafka
   metadata:
     name: my-cluster
     annotations:
       strimzi.io/node-pools: enabled
       strimzi.io/kraft: enabled
   spec:
     kafka:
       config:
         offsets.topic.replication.factor: 3
         transaction.state.log.replication.factor: 3
         transaction.state.log.min.isr: 2
         default.replication.factor: 3
         min.insync.replicas: 2
       listeners:
         - name: plain
           port: 9092
           type: internal
           tls: false
         - name: tls
           port: 9093
           type: internal
           tls: true
       version: 4.0.0
       metadataVersion: 4.0
     entityOperator:
       topicOperator: {}
       userOperator: {}

3. Click Create to start the installation of Kafka.

   The Kafka resource remains in a pending state until at least one node pool is created.

4. Click Create instance under KafkaNodePool to create a node pool instance.

   Switch to YAML view and paste a minimal broker pool configuration with ephemeral storage:

   apiVersion: kafka.strimzi.io/v1beta2
   kind: KafkaNodePool
   metadata:
     name: broker
     labels:
       strimzi.io/cluster: my-cluster
   spec:
     replicas: 3
     roles:
       - broker
     storage:
       type: jbod
       volumes:
         - id: 0
           type: ephemeral

5. Click Create instance under KafkaNodePool to create a second node pool instance.

   Switch to YAML view and paste a minimal controller pool configuration with ephemeral storage:

   apiVersion: kafka.strimzi.io/v1beta2
   kind: KafkaNodePool
   metadata:
     name: controller
     labels:
       strimzi.io/cluster: my-cluster
   spec:
     replicas: 3
     roles:
       - controller
     storage:
       type: jbod
       volumes:
         - id: 0
           type: ephemeral
           kraftMetadata: shared

6. Select the Kafka page to show the installed Kafka clusters. Wait until the status of the Kafka cluster changes to Ready.
