iziworktech/kafka repository overview

⁠iziwork kafka image

We could not find a Kafka v3.2.0 image available for both amd64 and aarch64, so we made our own.

GitHub repository: https://github.com/Iziwork/image-kafka⁠

⁠Versioning

The images are tagged with the version of Kafka, the Scala version being ignored (we always use the latest available).

Example for Kafka 3.2.0 (if this is the latest): latest, 3.2.0, 3.2, 3.

⁠Configuration

The default server.properties Kafka configuration file is used, with the following patches applied:

• log.dirs=/data, and the image specifies a /data volume
• Any KAFKA_CFG_<PROPERTY> environment variable value. For example, KAFKA_CFG_PROCESS_ROLES=broker,controller would result in a process.roles=broker,controller appended to the configuration

If you want complete control over the Kafka configuration, just add a /opt/kafka/config/server.properties.final file and it will be used instead, without the above patches.

⁠Enable KRaft

If you want to use Kafka without Zookeeper, you can enable KRaft with the KAFKA_ENABLE_KRAFT (any value) environement variable. On start, the image will make sure the storage directory is formatted (in other words, kafka-storage.sh format will be ran).
