注：在manage上创建overlay网络后，各node上并没有同步创建该网络，只有当使用该overlay网络的容器在node节点上运行时，才会在node节点上自动创建,容器删除后，网络也会在node节点上删除。
（4）将容器绑定到自定义的网络中
$docker service create --network net3 --replicas 4 --name time-php registry.cntv.net/heqin/tvtime-php:v0.85dongsi
5qiv4hhv7ra5p65fpq2v6ok0x
$docker service ls
5qiv4hhv7ra5 time-php 4/4 registry.cntv.net/heqin/tvtime-php:v0.85dongsi
$docker service ps time-php

进入swarm3 ，可以看到net3网络下有两个容器。
$docker docker network inspect net3

用swarm3的容器去ping swarm2主机上的容器，是可以ping通的
$docker exec -it d8fa64c4f835 ping 10.88.0.3
