deploy

Docker1.13推出了一个新版本的Docker Compose（V3）。该版本的主要特征是，允许Swarm Mode使用Docker Compose文件定义直接部署服务。

定义compose-file

[root@swarm-manager ~]# cat docker-compose.yml 
version: '3'
services:
  mysql:
    image: mysql
    environment:
      - MYSQL_ROOT_PASSWORD=password
  wordpress:
    image: wordpress
    ports:
      - 80:80
    links:
      - mysql:mysql
    environment:
      - WORDPRESS_DB_PASSWORD=password

在Swarm Mode下，需要使用docker stack deploy命令进行部署，如果直接使用docker-compose up则将会出现如下警告：

[root@swarm-manager ~]# docker-compose up
WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

通过compose-file部署多个Service

给容器服务的Kubernetes集群部署network policy支持
随着使用容器部署微服务的流行，容器平台上的服务间有复杂的调用关系。kubernetes为了满足服务间调用的访问控制，在1.3的版本中便引入了Network Policy，通过它可以实现通过标签方便的去定义访问的策略 。

replicated mode vs global mode - 每天5分钟玩转 Docker 容器技术（105）
Swarm 可以在 service 创建或运行过程中灵活地通过 --replicas 调整容器副本的数量，内部调度器则会根据当前集群的资源使用状况在不同 node 上启停容器，这就是 service 默认的 replicated mode。
