使用 docker 启动 kafka 服务 without zookeeper

简化配置：

version: "3"
services:
  shezheng_kafka:
    image: 'bitnami/kafka:3.2'
    hostname: shezheng_kafka
    container_name: shezheng_kafka
    volumes:
      - ./data/kafka:/bitnami/kafka
    user: root
    network_mode: bridge
    ports:
     - '19092:9092'
    environment:
      - KAFKA_ENABLE_KRAFT=yes
      - KAFKA_CFG_PROCESS_ROLES=broker,controller
      - KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER
      - KAFKA_CFG_LISTENERS=PLAINTEXT://:9092,CONTROLLER://:9093 # 服务端监听的地址
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT
      - KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://shezheng_kafka:9092
      - KAFKA_BROKER_ID=1

      - KAFKA_CFG_CONTROLLER_QUORUM_VOTERS=1@shezheng_kafka:9093
      - ALLOW_PLAINTEXT_LISTENER=yes
      - AUTO_CREATE_TOPICS=true
      - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://172.18.103.22:19092 # 客户端连接的地址
      - KAFKA_NUM_PARTITIONS=51

不依赖于 zookeeper 的方案。

• LISTENERS are what interfaces Kafka binds to.
• ADVERTISED_LISTENERS are how clients can connect.
