docker搭建kafka集群

新建docker-compose.yml，内容如下：

version: "2"

services:
  zookeeper:
    user: root
    image: docker.io/bitnami/zookeeper:3.7
    ports:
      - "12181:2181"
    environment:
      - ALLOW_ANONYMOUS_LOGIN=yes
    volumes:
      - zookeeper_data:/bitnami/zookeeper
  kafka-0:
    image: docker.io/bitnami/kafka:2
    ports:
      - "19090:19090"
    environment:
      - KAFKA_CFG_ZOOKEEPER_ConNECT=zookeeper:2181
      - KAFKA_CFG_BROKER_ID=0
      - ALLOW_PLAINTEXT_LISTENER=yes
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CLIENT:PLAINTEXT,EXTERNAL:PLAINTEXT

      - KAFKA_INTER_BROKER_LISTENER_NAME=CLIENT
    volumes:
      - kafka_0_data:/bitnami/kafka
    depends_on:
      - zookeeper
  kafka-1:
    image: docker.io/bitnami/kafka:2
    ports:
      - "19091:19091"
    environment:
      - KAFKA_CFG_ZOOKEEPER_ConNECT=zookeeper:2181
      - KAFKA_CFG_BROKER_ID=1
      - ALLOW_PLAINTEXT_LISTENER=yes

      - KAFKA_CFG_ADVERTISED_LISTENERS=CLIENT://kafka-1:9092,EXTERNAL://localhost:19091
      - KAFKA_INTER_BROKER_LISTENER_NAME=CLIENT
    volumes:
      - kafka_1_data:/bitnami/kafka
    depends_on:
      - zookeeper
  kafka-2:
    image: docker.io/bitnami/kafka:2
    ports:
      - "19092:19092"
    environment:
      - KAFKA_CFG_ZOOKEEPER_ConNECT=zookeeper:2181
      - KAFKA_CFG_BROKER_ID=2
      - ALLOW_PLAINTEXT_LISTENER=yes
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CLIENT:PLAINTEXT,EXTERNAL:PLAINTEXT
      - KAFKA_CFG_LISTENERS=CLIENT://:9092,EXTERNAL://:19092
      - KAFKA_CFG_ADVERTISED_LISTENERS=CLIENT://kafka-2:9092,EXTERNAL://localhost:19092
      - KAFKA_INTER_BROKER_LISTENER_NAME=CLIENT
    volumes:
      - kafka_2_data:/bitnami/kafka
    depends_on:
      - zookeeper

volumes:
  zookeeper_data:
    driver: local
  kafka_0_data:
    driver: local
  kafka_1_data:
    driver: local
  kafka_2_data:
    driver: local

当前目录运行命令

docker compose -f ./docker-compose.yml up

结果
