"Apache Kafka for OpenShift"

Run Apache Kafka and Apache ZooKeeper on OpenShift v3.

This was developed for demonstration purposes. Use in environments where you do not need persistence in the face of failures or configuration tuning for scale.

The architecture is as follows:

• 1 pod containing a container for Apache Kafka and Apache ZooKeeper
• 1 service to access the containers

Quick start

1. Load resources (Templates, DeploymentConfigs, Services)

oc create -f https://raw.githubusercontent.com/mattf/openshift-kafka/master/resources.yaml

2. Deploy the Apache Kafka + Apache Zookeeper pod

oc new-app apache-kafka

Follow the Apache Kafka Documentation Quick Start

3. Deploy a debugging container and connect to it

oc run -it --rm kafka-debug --image=mattf/openshift-kafka --command -- bash

4. Create a topic

bin/kafka-topics.sh --create --zookeeper apache-kafka --replication-factor 1 --partitions 1 --topic test

5. List topics

bin/kafka-topics.sh --list --zookeeper apache-kafka

6. Send some messages

bin/kafka-console-producer.sh --broker-list apache-kafka:9092 --topic test <<EOF
foo
bar
baz
EOF

7. Receive some messages

bin/kafka-console-consumer.sh --bootstrap-server apache-kafka:9092 --topic test --from-beginning
