We could not find a Kafka v3.3.2 image available for both amd64 and aarch64, so we made our own.
The images are tagged with the version of Kafka, the Scala version being ignored (we always use the latest available).
Example for Kafka 3.3.2 (if this is the latest): latest, 3.3.2, 3.3, 3.
The default server.properties Kafka configuration file is used, with the following patches applied:
log.dirs=/data, and the image specifies a/datavolume- Any
KAFKA_CFG_<PROPERTY>environment variable value. For example,KAFKA_CFG_PROCESS_ROLES=broker,controllerwould result in aprocess.roles=broker,controllerappended 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.
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).
The image is released automatically on merge on main.
