Kafka on Docker and Spring Producer Application

Using bitnami stack

Check their guide - there are a lot of insights on how it works + Kafka cluster + more

I think your listener's address is not configured well. It should be localhost or the actual docker host name.

This is a working example from my project. Note that I use the original confluence image, but it should work with wurstmeister's image too:

version: '3.7'services:  zookeeper:    image: confluentinc/cp-zookeeper    hostname: zookeeper    environment:      ZOOKEEPER_SERVER_ID: 1      ZOOKEEPER_CLIENT_PORT: "2181"      ZOOKEEPER_TICK_TIME: "2000"      ZOOKEEPER_SERVERS: "zookeeper:22888:23888"    ports:      - 2181:2181  kafka:    image: confluentinc/cp-kafka    hostname: kafka    depends_on:      - zookeeper    environment:      KAFKA_ZOOKEEPER_CONNECT: "zookeeper:2181"      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT,PLAINTEXT_UI:PLAINTEXT      KAFKA_INTER_BROKER_LISTENER_NAME: PLAINTEXT      KAFKA_LISTENERS: PLAINTEXT://kafka:29092,PLAINTEXT_HOST://kafka:9092      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:29092,PLAINTEXT_HOST://localhost:9092      KAFKA_BROKER_ID: 1      KAFKA_BROKER_RACK: "r1"      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1      KAFKA_DELETE_TOPIC_ENABLE: "true"      KAFKA_AUTO_CREATE_TOPICS_ENABLE: "true"    ports:      - 9092:9092      - 29092:29092

My docker-compose file:
