docker swarm集群安装使用

1、安装master

?

1 2 3 4 5 6 7 8

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　

?

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

3、启动服务、查看服务

?

1 2 3 4

#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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

[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。
