Docker集群实验环境布署--swarm【4 管理组件--manager】

主机分配如下,支持双活,中断其中1台,primary会通过consul自动重新选举
 
10.40.100.141 docker-manager0.venic.com
10.40.100.142 docker-manager1.venic.com
 
首先在镜像服务器上148上,拉取一个官网 的 consul镜像,方便等下在其它三台上快速启动
# docker pull  swarm && docker tag swarm:latest docker-registry.venic.com:5000/swarm:latest
# docker push docker-registry.venic.com:5000/swarm:latest
 
 
 
 
10.40.100.141上
docker run -d -p 4000:4000  --restart=always --name manager0 docker-registry.venic.com:5000/swarm:latest manage -H :4000 --replication --advertise 10.40.100.141:4000 consul://docker-consul.venic.com:8500
 
 
10.40.100.142上
docker run -d -p 4000:4000 --restart=always --name manager1 docker-registry.venic.com:5000/swarm:latest manage -H :4000 --replication --advertise 10.40.100.142:4000 consul://docker-consul.venic.com:8500
 
 
在2台机器上执行查看状态,可以看到选举了谁做主
