Docker部署ZooKeeper分布式协调服务

1、准备工作

docker pull zookeeper:3.6.3
Pwd="/data/software/zookeeper"
mkdir -p ${Pwd}/{logs,data,conf}

2、创建TEST容器，将conf目录COPY出来，在映射进去，方便后续维护管理！

docker run -itd --name zookeeper zookeeper:3.6.3
docker cp zookeeper:/conf ${Pwd}
docker rm -f zookeeper

3、运行容器

docker run -itd --name zookeeper \
    -v ${Pwd}/data:/data \
    -v ${Pwd}/logs:/datalog \
    -v ${Pwd}/conf:/conf \
    -v /etc/localtime:/etc/localtime \
    -p 2181:2181 \
    --restart=always \
    zookeeper:3.6.3

4、测试链接zookeeper

docker exec -it zookeeper zkCli.sh

正常输出内容：
