docker容器搭建zookeeper集羣

1.下載鏡像：docker pull zookeeper

2.寫配置文件：vi docker-compose.yml

version: '3.1'
services:
    zoo1:
        image: zookeeper
        restart: always
        hostname: zoo1
        ports:
            - 2181:2181
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo2:
        image: zookeeper
        restart: always
        hostname: zoo2
        ports:
            - 2182:2181
        environment:
            ZOO_MY_ID: 2
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo3:
        image: zookeeper
        restart: always
        hostname: zoo3
        ports:
            - 2183:2181
        environment:
            ZOO_MY_ID: 3
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

3.啓動：docker-compose up -d

4.以交互的方式進出zookeeper,查看主從關係

docker exec -it zookeeper_zoo1_1 /bin/bash
