docker swarm集群安装使用

1、安装master

docker swarm init --advertise-addr 10.98.10.186
Swarm initialized: current node (qemrm3oqc537jpcsp0vqb60s6) is now a manager.

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

    docker swarm join --token SWMTKN-1-3j15bhg901hjyrqpdnrdmgk9k6thpnltq9y3d8c10m7hr4dags-a3kdkgzhdln7n5ofs4udfzwx9 10.98.10.186:2377

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

2、添加work node　

docker swarm join --token SWMTKN-1-3j15bhg901hjyrqpdnrdmgk9k6thpnltq9y3d8c10m7hr4dags-a3kdkgzhdln7n5ofs4udfzwx9 10.98.10.186:2377

3、启动服务、查看服务

#部署服务
docker service create --replicas 1 --network nginx_net --name my_nginx -p 80:80 -d nginx    # 就创建了一个具有一个副本（--replicas 1 ）的nginx服务，使用镜像nginx
#查看服务
[root@localhost ~]# docker service ls

4、部署portainer 管理docker swarm

[root@manager swar]# more docker-compose.yml 
version: '3.2'
 
services:
  agent:
    image: portainer/agent:latest
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /var/lib/docker/volumes:/var/lib/docker/volumes
    networks:
      - agent_network
    deploy:
      mode: global
      placement:
        constraints: [node.platform.os == linux]
 
  portainer:
    image: portainer/portainer-ce:2.16.2
    command: -H tcp://tasks.agent:9001 --tlsskipverify
    ports:
      - "9443:9443"
      - "9000:9000"
      - "8000:8000"
    volumes:
      - portainer_data:/data
    networks:
      - agent_network
    deploy:
      mode: replicated
      replicas: 1
      placement:
        constraints: [node.role == manager]
 
networks:
  agent_network:
    driver: overlay
    attachable: true
 
volumes:
  portainer_data:

5、启动服务

#docker stack deploy -c docker-compose.yml portainer 
Creating network portainer_agent_network
Creating service portainer_agent
Creating service portainer_portainer

6、部署、运行成功之后，我们可以通过下面的地址来访问portainer-ce的管理页面。
