docker swarn搭建

以下操作均在root用户下，其他用户请加上sudo

机器列表：

Name	Role	Cpu	Memory	Ip
docker1	manager	4	8.2 GB	192.168.1.101
docker2	worker	4	8.2 GB	192.168.1.102

分别进行linux安装docker

完成镜像加速配置即可，后续不用继续进行

初始化集群

注意所有节点docker 服务必须已启动

• 在manager 节点上执行

docker swarm init --advertise-addr  192.168.1.101

• 结果

Swarm initialized: current node (oqela4wtpa9m7e8a6zi9k9rbl) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-03md8tqw24sd0tbxkyqxmiay5nixniax9c301f49qjorhsj069-44eeph3lldj3lopzk7tiiv1ve 192.168.1.101:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

• 在worker节点上运行

docker swarm join --token SWMTKN-1-4ilbka9hoz58wapezioxy7pnaq0rbhucokrzl7joukhibwsf3g-0h7k726dvpmftzu4rij88f7lc 192.168.1.101:2377

• 结果

This node joined a swarm as a worker.

• 验证

## manager节点运行命令。
docker node ls
## 结果如下
ID                            HOSTNAME            STATUS              AVAILABILITY        MANAGER STATUS      ENGINE VERSION

部署GUI

docker service create --name portainer --publish 9000:9000 --constraint 'node.role == manager' --mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock portainer/portainer -H unix:///var/run/docker.sock

部署可视化

docker service create --name=viz --publish=8088:8080/tcp --constraint=node.role==manager --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock manomarks/visualizer

验证

• open http://192.168.1.101:9000

首次打开会提示创建管理员账户

• open http://192.168.1.101:8088或者点击上个页面中Go to cluster visualizer
