Just start hello-kafka using docker compose

> docker compose up --build

The hello-kafka container will exit after submiting and receiving a message to kafka. The kafka container will go on.

Stop hello-kafka

> docker compose down

Look at the log file of container hello-kafka.

Output schould be similar to that:
