下载镜像

docker pull zookeeper

zk集群的搭建 docker-compose.yml脚本

version: '2'
services:
    zoo1:
        image: docker.io/zookeeper
        restart: always
        container_name: zoo1
        ports:
            - "2182:2181"
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo2:
        image: docker.io/zookeeper
        restart: always
        container_name: zoo2
        ports:
            - "2183:2181"
        environment:
            ZOO_MY_ID: 2
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo3:
        image: docker.io/zookeeper
        restart: always
        container_name: zoo3
        ports:
            - "2184:2181"
        environment:
            ZOO_MY_ID: 3
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

启动与查看

COMPOSE_PROJECT_NAME=zk_test docker-compose up -d

COMPOSE_PROJECT_NAME=zk_test docker-compose ps

连接 ZK 集群

1、使用 Docker 命令行客户端连接 ZK 集群

docker run -it --rm \
        --link zoo1:zk1 \
        --link zoo2:zk2 \
        --link zoo3:zk3 \
        --net zktest_default \
        zookeeper zkCli.sh -server zk1:2181,zk2:2181,zk3:2181
        
        
        
        
2、通过本地主机连接 ZK 集群
bin路径下：
zkCli.sh -server localhost:2182,localhost:2183,localhost:2184

查看集群

1、yum -y install nc 下载nc命令

2、echo stat | nc 127.0.0.1 2182
   echo stat | nc 127.0.0.1 2183
   echo stat | nc 127.0.0.1 2184
