一、部署kafka

1. 创建项目目录

mkdir kafka-docker && cd kafka-docker

2. 创建 docker-compose.yml 文件

vim docker-compose.yml

version: '3.8'
services:
  zookeeper:
    image: confluentinc/cp-zookeeper:7.4.0
    container_name: zookeeper
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
      ZOOKEEPER_TICK_TIME: 2000
    ports:
      - "2181:2181"
    networks:
      - kafka-net

  kafka:
    image: confluentinc/cp-kafka:7.4.0
    container_name: kafka
    depends_on:
      - zookeeper
    ports:
      - "9092:9092"
    environment:
      KAFKA_BROKER_ID: 1
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
      KAFKA_AUTO_CREATE_TOPICS_ENABLE: "true"
      KAFKA_DELETE_TOPIC_ENABLE: "true"
      KAFKA_NUM_PARTITIONS: 3
    volumes:
      - ./kafka-data:/var/lib/kafka/data
    networks:
      - kafka-net

  kafka-ui:
    image: provectuslabs/kafka-ui:latest
    container_name: kafka-ui
    depends_on:
      - kafka
    ports:
      - "8080:8080"
    environment:
      KAFKA_CLUSTERS_0_NAME: local
      KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS: kafka:9092
      KAFKA_CLUSTERS_0_ZOOKEEPER: zookeeper:2181
    networks:
      - kafka-net

networks:
  kafka-net:
    driver: bridge

volumes:
  kafka-data:

3. 启动服务

docker-compose up -d

4. 查看服务状态

docker-compose ps

二、 验证部署服务

1. 检查容器状态

docker ps

2.查看 Kafka 日志

docker logs kafka

3. 测试 Kafka 连接

docker exec -it kafka kafka-topics --list --bootstrap-server localhost:9092
