1、安装docker-compose

有关的介绍可以看官方GitHub : https://github.com/docker/compose

安装docker-compose

curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

查看是否安装成功

[root@izbp13196wp34obmnd4avdz ~]# docker-compose --version
docker-compose version 1.24.1, build 4667896b

2、编写docker-compose.yml配置文件

version: '3.1'
services:
  zoo1:
    image: zookeeper
    restart: always
    hostname: zoo1
    ports:
      - 2184:2181
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181

  zoo2:
    image: zookeeper
    restart: always
    hostname: zoo2
    ports:
      - 2182:2181
    environment:
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=0.0.0.0:2888:3888;2181 server.3=zoo3:2888:3888;2181

  zoo3:
    image: zookeeper
    restart: always
    hostname: zoo3
    ports:
      - 2183:2181
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=0.0.0.0:2888:3888;2181

3、启动zookeeper集群

[root@rocketmq02 ~]# docker-compose up -d
Creating network "root_default" with the default driver
Creating root_zoo2_1 ... done
Creating root_zoo1_1 ... done
Creating root_zoo3_1 ... done

4、查看集群状态

[root@rocketmq02 ~]# docker ps
CONTAINER ID   IMAGE                                       COMMAND                  CREATED          STATUS          PORTS                                                                                                                             NAMES
38f54f273e8b   zookeeper                                   "/docker-entrypoint.…"   8 seconds ago    Up 5 seconds    2888/tcp, 3888/tcp, 8080/tcp, 0.0.0.0:2184->2181/tcp, :::2184->2181/tcp                                                           root_zoo1_1
a1c132eb4cbb   zookeeper                                   "/docker-entrypoint.…"   8 seconds ago    Up 5 seconds    2888/tcp, 3888/tcp, 8080/tcp, 0.0.0.0:2183->2181/tcp, :::2183->2181/tcp                                                           root_zoo3_1
c92e46937717   zookeeper                                   "/docker-entrypoint.…"   8 seconds ago    Up 7 seconds    2888/tcp, 3888/tcp, 8080/tcp, 0.0.0.0:2182->2181/tcp, :::2182->2181/tcp                                                           root_zoo2_1

登录测试如下

使用 Docker 命令行客户端连接 ZK 集群

[root@rocketmq02 ~]# docker run -it --rm         --link zoo1:zk1         --link zoo2:zk2         --link zoo3:zk3         --net root_default         zookeeper zkCli.sh -server zk1:2184,zk2:2181,zk3:2181
