第 14 章 Setting up client access to a Kafka cluster
After you have deployed Streams for Apache Kafka, you can set up client access to your Kafka cluster. To verify the deployment, you can deploy example producer and consumer clients. Otherwise, create listeners that provide client access within or outside the OpenShift cluster.

Deploy example producer and consumer clients to send and receive messages. You can use these clients to verify a deployment of Streams for Apache Kafka.
Prerequisites
- The Kafka cluster is available for the clients.
Procedure
Deploy a Kafka producer.
oc run kafka-producer -ti --image=registry.redhat.io/amq-streams/kafka-37-rhel9:2.7.0 --rm=true --restart=Never -- bin/kafka-console-producer.sh --bootstrap-server cluster-name-kafka-bootstrap:9092 --topic my-topic- Type a message into the console where the producer is running.
- Press Enter to send the message.
Deploy a Kafka consumer.
oc run kafka-consumer -ti --image=registry.redhat.io/amq-streams/kafka-37-rhel9:2.7.0 --rm=true --restart=Never -- bin/kafka-console-consumer.sh --bootstrap-server cluster-name-kafka-bootstrap:9092 --topic my-topic --from-beginning- Confirm that you see the incoming messages in the consumer console.
