搭建swarm

### portainer集群部署

 curl -L https://downloads.portainer.io/portainer-agent-stack.yml -o portainer-agent-stack.yml

docker stack deploy -c portainer-agent-stack.yml portainer

​

### 搭建swarm

1、先安装docker

2、机器环境

```
192.168.239.131           marster 
192.168.239.147           node1

设置主机名

在marster节点上
[root@marster ~]# hostnamectl --static set-hostname master
 
在node1节点上
[root@node1 ~]# hostnamectl --static set-hostname node1

```

3、格式化swarm```

[root@master ~]# docker swarm init --advertise-addr 192.168.239.131
Swarm initialized: current node (pza1tdiot2cvpaenmf9pvvq8v) is now a manager.

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

    docker swarm join --token SWMTKN-1-1ols0pte3ruh9n58oldkkca6rj5d52p8dcmjs2l4p4fh9perw9-5vt6wk3exxrqh6eqq92jgh5mv 192.168.239.128:2377

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

[root@master ~]# docker node ls  #查看
ID                            HOSTNAME            STATUS              AVAILABILITY        MANAGER STATUS      ENGINE VERSION
pza1tdiot2cvpaenmf9pvvq8v *   master              Ready               Active              Leader              19.03.0
```

4、node节点加入

```

[root@node1 ~]# docker swarm join --token SWMTKN-1-1ols0pte3ruh9n58oldkkca6rj5d52p8dcmjs2l4p4fh9perw9-5vt6wk3exxrqh6eqq92jgh5mv 192.168.239.128:2377
This node joined a swarm as a worker.

```

5、创建nginx服务

```
#--name表示服务名称，--replicas表示副本任务数，--publish表示端口映射，将容器的80端口映射到物理机的80端口，nginx表示使用nginx镜像

[root@master ~]# docker service create --name web --publish 80:80 --replicas 3 nginx

#查看服务状态信息

[root@master ~]# docker service ls
ID                  NAME                MODE                REPLICAS            IMAGE               PORTS
b05r6bo43rpp        web                 replicated          3/3                 nginx:latest        *:80->80/tcp
[root@master ~]# docker service ps web

```
