Crude, but semi-clean containerized Kafka cluster for prototyping and teaching purposes. There are a couple of niceties I want to add to it, but they'll come later.

To get the cluster running:

docker compose up -d

To get rid of the cluster:

docker compose down

docker compose exec -it [node service name] /bin/bash

The container image stores the usual Kafka command line utilities in /usr/bin.

docker compose exec -it [kafka node service name] /bin/bash

zookeeper-shell $ZOOKEEPER

You'll end up with a barebones JLine-free minimally usable ZK shell.

• Mount host volumes in the containers to use as the cluster's data directories; also add some scripts for deleting the contents thereof during a full teardown.
• Possibly add kafka-ui container
• Possibly add some of the Confluent platform images from confluentinc/cp-* on Docker Hub, assuming I end up needing them for what I ultimately use this for.
