简单记一笔，docker下zookeeper集群搭建

镜像下载

执行如下命令

docker pull zookeeper

默认会从官方镜像库拉取最新zk镜像

xxx>docker pull zookeeper

2.集群搭建

使用docker-compose来启动多个zk容器

先编写一个docker-compose-zookeeper.yaml文件

version: '3'

services:
  zoo1:
    image: zookeeper
    restart: always
    hostname: zoo1

networks:
  zookeeper:
    driver: bridge

　　执行上边写好的文件

# 启动所有Zookeeper服务
docker-compose -f docker-compose-zookeeper.yaml up -d

　　使用客户端去连接测试，我这里使用的是ZooInspector

# 命令行中打开
D:\download\ZooInspector\build>java -jar zookeeper-dev-ZooInspector.jar

　　效果：下边是创建好的节点
