zk叢集的搭建 docker-compose.yml指令碼

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
 

啟動與檢視

COMPOSE_PROJECT_NAME=zk_test docker-compose up -d

COMPOSE_PROJECT_NAME=zk_test docker-compose ps

連線 ZK 叢集

1、使用 Docker 命令列客戶端連線 ZK 叢集

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、通過本地主機連線 ZK 叢集
bin路徑下：
zkCli.sh -server localhost:2182,localhost:2183,localhost:2184
 

檢視叢集

1、yum -y install nc 下載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
