Docker:Kafka安装

注意如果从docker外部连接的话需要增加额外的配置，如下：

version: "2"

services:
  zookeeper:
    image: docker.io/bitnami/zookeeper:3.7
    ports:
      - "2181:2181"
    volumes:
      - "zookeeper_data:/bitnami"
    environment:
      - ALLOW_ANONYMOUS_LOGIN=yes
  kafka:
    image: docker.io/bitnami/kafka:3
    ports:
      - "9093:9093"
    volumes:
      - "kafka_data:/bitnami"
    mem_limit: 4096M
    mem_reservation: 1024M
    cpus: 4
    environment:
      - KAFKA_CFG_ZOOKEEPER_CONNECT=zookeeper:2181
      - ALLOW_PLAINTEXT_LISTENER=yes
      - KAFKA_HEAP_OPTS=-Xmx3072m -Xms1024m
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CLIENT:PLAINTEXT,EXTERNAL:PLAINTEXT
      - KAFKA_CFG_LISTENERS=CLIENT://:9092,EXTERNAL://:9093
      - KAFKA_CFG_ADVERTISED_LISTENERS=CLIENT://kafka:9092,EXTERNAL://localhost:9093
      - KAFKA_INTER_BROKER_LISTENER_NAME=CLIENT
    depends_on:
      - zookeeper

volumes:
  zookeeper_data:
    driver: local
  kafka_data:
    driver: local

客户端（kafka tool）中需要设置bootstrap server为localhost:9093
