Hi together, I found a wrong configuration for the docker-compose.yml example in https://hub.docker.com/r/apache/kafka
The configurations KAFKA_LISTENERS: PLAINTEXT://localhost:9092,CONTROLLER://localhost:9093 KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092 do not work. I had to remove "localhost" to be able to connect to the broker: KAFKA_LISTENERS: PLAINTEXT://:9092,CONTROLLER://:9093 KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://:9092 I couldn't find the appropriate repository to create a pull request, so I'm sending this via email. Thanks for your great work! Robert Zilke
