swarm模式下docker-compose配置zookeeper分布式集群

$ 前言

• 记录一次,在docker swarm 下利用docker-compose创立的3个节点的zookeer分布式集群.

$ docker环境下常用到的命令

####docker启动单个窗口docker start 容器名####docker中止单个容器docker stop 容器名####中止删除所有容器docker stop $(docker ps -a -q)  && docker rm   $(docker ps -a -q) -f####删除所有镜像docker image rm $(docker images -q) -f####删除无用的卷docker volume prune####查看docker日志文件大小ls -lh $(find /var/lib/docker/containers/ -name *-json.log)####查找大文件find / -type f -size +100M####docker-compose方式创立启动容器docker-compose -f zk.yml up -d####docker-compose方式中止销毁容器docker-compose -f zk.yml down

首先创立一个Docker网卡

#创立swarm网络docker network create -d overlay service_ov_net  --attachable  --subnet 172.169.0.0/16 --gateway 

zookeeper配置 zk.yml 配置说明

• x-logging 配置docker容器的日志文件大小最大256m 最多3个
• networks 指定网络为我们上面创立的网络
• volumes 不需要刻意创立,docker默认会在/var/lib/docker/volume/ 进行创立
• ZOO_MY_ID: 配置各个节点的ID
• ZOO_SERVERS: server.1 配置各个节点的连接地址
• ZOO_AUTOPURGE_PURGEINTERVAL: 配置1个小时清除一下zk日志
• ZOO_AUTOPURGE_SNAPRETAINCOUNT: 配置最多保留3个zk日志
