docker-compose搭建

1、docker-compose

        1.首先准备好docker服务

        2.下载docker-compose：时间较长

                sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

        3.添加docker-compose执行权限

               sudo chmod +x /usr/local/bin/docker-compose

        4.验证：docker-compose --version

        5.创建zookeeper和kafka单点的docker-compose.yml文件

version: '3'
services:
  zookeeper:
    image: wurstmeister/zookeeper:latest
    ports:
      - "2181:2181"
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=0.0.0.0:2888:3888
 
  kafka:
    image: wurstmeister/kafka:latest
    ports:
      - "9092:9092"
    expose:
      - "9093"  # Internal listener, not exposed to host
    environment:
      KAFKA_ADVERTISED_LISTENERS: INSIDE://kafka:9093,OUTSIDE://localhost:9092
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INSIDE:PLAINTEXT,OUTSIDE:PLAINTEXT
      KAFKA_LISTENERS: INSIDE://0.0.0.0:9093,OUTSIDE://0.0.0.0:9092
      KAFKA_INTER_BROKER_LISTENER_NAME: INSIDE
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - zookeeper

        6.在文件所在目录下运行：docker-compose up -d (注意：-d是后台运行)

        7.docker ps查看是否启动成功

        8.进入kafka容器：docker exec -it zookeeper-kafka-kafka-1 bash

        9.进入kafka脚本目录：/opt/kafka_2.13-2.8.1/bin，注意：对应自己安装的kafka版本，
