Docker安装Kafka（不依赖ZooKeeper）

创建docker-compose.yaml

version: "3.9" #版本号
services:
  kafka:
    image: apache/kafka:3.9.0
    container_name: kafka
    hostname: kafka
    ports:
      - 9092:9092  # 容器内部之间使用的监听端口
      - 9094:9094  # 容器外部访问监听端口
    environment:
      KAFKA_NODE_ID: 1
      KAFKA_PROCESS_ROLES: broker,controller
      # 外部访问监听端口为 9092，容器内部使用不同的端口 9094
      KAFKA_LISTENERS: PLAINTEXT://0.0.0.0:9094,CONTROLLER://localhost:9093,PLAINTEXT_CONTAINER://kafka:9092
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9094,PLAINTEXT_CONTAINER://kafka:9092
      KAFKA_CONTROLLER_LISTENER_NAMES: CONTROLLER
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,PLAINTEXT_CONTAINER:PLAINTEXT
      KAFKA_CONTROLLER_QUORUM_VOTERS: 1@localhost:9093
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
      KAFKA_TRANSACTION_STATE_LOG_REPLICATION_FACTOR: 1
      KAFKA_TRANSACTION_STATE_LOG_MIN_ISR: 1
      KAFKA_GROUP_INITIAL_REBALANCE_DELAY_MS: 0
      KAFKA_NUM_PARTITIONS: 3
      KAFKA_LOG_DIRS: /var/lib/kafka/data
    volumes:
      - ./data/kafka/data:/var/lib/kafka/data

运行docker-compose.yaml

docker compose -f ./docker-compose.yaml up -d

测试kafka

• 进入容器

docker exec -it kafka bash 

• 创建topic

/opt/kafka/bin/kafka-topics.sh --bootstrap-server kafka:9092 --create --topic topic-test

• 打开生产者，在终端发送消息

/opt/kafka/bin/kafka-console-producer.sh --bootstrap-server kafka:9092 --topic topic-test

• 另外打开一个终端，进入容器

docker exec -it kafka bash 

• 打开消费者，接收消息

/opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server kafka:9092 --topic test-topic --from-beginning
