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`.

此指令可以查看所有用docker-compose 开启的容器的ip，结果类似下图，可以用对应的ip地址进行内部通讯
