集群模式

准备 3 台 Ubuntu Server 系统，并分别配置 Zookeeper

第一台主机

docker-compose.yml

version: '3.1'
services:
    zoo1:
        image: zookeeper
        restart: always
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=192.168.75.130:2888:3888 server.2=192.168.75.134:2888:3888 server.3=192.168.75.135:2888:3888
        network_mode: host

验证测试

root@UbuntuBase:/usr/local/docker/zookeeper# docker exec -it zookeeper_zoo1_1 /bin/bash
bash-4.3# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Mode: leader

第二台主机

docker-compose.yml

version: '3.1'
services:
    zoo2:
        image: zookeeper
        restart: always
        environment:
            ZOO_MY_ID: 2
            ZOO_SERVERS: server.1=192.168.75.130:2888:3888 server.2=192.168.75.134:2888:3888 server.3=192.168.75.135:2888:3888
        network_mode: host

验证测试

root@UbuntuBase:/usr/local/docker/zookeeper# docker exec -it zookeeper_zoo2_1 /bin/bash
bash-4.3# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Mode: follower

第三台主机

docker-compose.yml

version: '3.1'
services:
    zoo3:
        image: zookeeper
        restart: always
        environment:
            ZOO_MY_ID: 3
            ZOO_SERVERS: server.1=192.168.75.130:2888:3888 server.2=192.168.75.134:2888:3888 server.3=192.168.75.135:2888:3888
        network_mode: host

验证测试

root@UbuntuBase:/usr/local/docker/zookeeper# docker exec -it zookeeper_zoo3_1 /bin/bash
bash-4.3# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
