get the project

Clone it

git clone [email protected]:quanturtle/kafka-docker-sample.git

Run it

docker compose up --build

zookeper starts

zookeeper  | ===> User
zookeeper  | uid=1000(appuser) gid=1000(appuser) groups=1000(appuser)
zookeeper  | ===> Configuring ...

kafka broker starts

broker     | ===> User
broker     | uid=0(root) gid=0(root) groups=0(root)
broker     | ===> Configuring ...

consumer and producer start

producer   | Giving Kafka a bit of time to start up…
consumer   | Giving Kafka a bit of time to start up…

after consumer is ready, producer should send 5 messages

producer   | a, test_topic, 0
producer   | b, test_topic, 0
producer   | c, test_topic, 0
producer   | d, test_topic, 0
producer   | e, test_topic, 0
producer exited with code 0

that should be received by consumer

consumer   | Message received: "a" from topic test_topic
consumer   |
consumer   | Message received: "b" from topic test_topic
consumer   |
consumer   | Message received: "c" from topic test_topic
consumer   |
consumer   | Message received: "d" from topic test_topic
consumer   |
consumer   | Message received: "e" from topic test_topic
consumer   |
consumer exited with code 0
