ubuntu/kafka is a rock for kafka maintained by https://canonical.com/.

Apache Kafka is an open-source distributed event streaming platform for high-performance data pipelines, streaming analytics and integrations.

Receives security updates and tracks the newest combination of Apache Kafka and Ubuntu. This repository is free to use and exempted from per-user rate limits.

Apache Kafka 3 Quickstart

To deploy a single-broker containerized Kafka, you need to first deploy the ZooKeeper service and make sure that the ZooKeeper service is reachable by Kafka.

First, create a network

bash
docker network create -d bridge kafka-network

Deploy the ZooKeeper service

bash
docker run --detach  --name zookeeper --network kafka-network ubuntu/zookeeper:3.8-22.04_edge

Finally, deploy the Kafka service

docker run --detach --name kafka --network kafka-network -p 9092:9092 ubuntu/kafka:3.9-22.04_edge

Apache Kafka 4 Quickstart

To deploy a single-broker containerized Kafka, create a network first:

bash
docker network create -d bridge kafka-network

Now, deploy the Apache Kafka service

docker run --detach \n  --name kafka \n  --network kafka-network \n  -p 9092:9092 \n  ubuntu/kafka:4.1-24.04_edge

To activate the Apache Kafka service, you need to format the logs directory and grant its ownership to the kafka user:

docker exec kafka \n  /opt/kafka/bin/kafka-storage.sh format \n  --standalone \n  --cluster-id $(cat /proc/sys/kernel/random/uuid | tr -d '-' | base64 | cut -b 1-22) \n  -c /etc/kafka/server.properties

docker exec kafka chown -R kafka:kafka /tmp/kraft-combined-logs/

Please note that the images tagged up to 3.1 are Dockerfile-base images, whereas from version 3.6.1 onward the images are now rocks.
