The current Docker Hub documentation for Kafka is based on the use of static voters. Since Kafka 4.0 utilizes dynamic voters, users following the doc of docker hub may encounter unexpected behavior. Due to the limited time available for the 4.0.0 release, a simple and quick solution is to revert to using static voters within the Docker image. This can be achieved by adding a configuration file with static voter definitions to the kafka/docker folder, keeping it separate from the main kafka/config directory. This approach allows us to encourage the use of dynamic voters in typical deployments while maintaining compatibility within the Docker image.
