Hello, this is Lee Do-won. You mentioned using Kafka KRaft mode. Instead of using the existing Zookeeper, you can easily run Kafka by starting it as a Kafka Docker container. If you use the image from https://hub.docker.com/apache/kafka, I understand it runs in KRaft mode by default. It's configured to run in single KRaft mode by specifying environment variables like KAFKA_PROCESS_ROLES=broker,controller. Practical content for running Kafka with Docker container images has been added. Please refer to it. If you have any additional questions, please leave another message. Thank you.
