Docker Stack命令使用

这里我们使用docker stack来部署docker swarm集群的服务，首先我们还是可以利用docker-compose.yml文件去编排需要安装部署的服务。还是以wordpress为例，

version: '3'

services:

  web:
    image: wordpress
    ports:
      - 8090:80 #map port 80 to 8090
    environment:
      WORDPRESS_DB_HOST: mysql
      WORDPRESS_DB_PASSWORD: root
    networks:
      - my-network
    depends_on:
      - mysql
    deploy:
      mode: replicated
      replicas: 3
      restart_policy:
        condition: on-failure
        delay: 5s
        max_attempts: 3
      update_config:
        parallelism: 1
        delay: 10s

  mysql:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: wordpress
    volumes:
      - mysql-data:/var/lib/mysql57
    networks:
      - my-network
    deploy:
      mode: global
      placement:
        constraints:
          - node.role == manager

volumes:
  mysql-data:

networks:
  my-network:
    driver: overlay

1.部署wordpress且指定compose file：

docker stack deploy wordpress -c docker-compose.yml

2.查询docker swarm的stacks：

docker stack ls

3.查看stack应用的所有任务：

docker stack ps wordpress

4.列出一个stack应用的所有服务：

docker stack sevices wordpress

5.删除stack：

docker stack rm wordpress

浏览器运行http://192.168.205.10:8090 可打开安装界面表示部署成功。
