本人菜鸟一枚，使用docker时遇到个问题，还望各位大神多多指点
操作环境：
虚拟机中的Centos7
ip 10.1.2.249
GW 10.1.2.254
docker 1.8
建立container test1
利用的工具pipwork
期望給test1分配固定IP 10.1.2.248
已经进行的尝试有
1、 http://www.infoq.com/cn/articles/docker-network-and-pipework-open-source-explanation-practice 这篇文章中利用pipwork 分配固定IP的方法
2、http://www.xiaomastack.com/2015/02/06/docker-static-ip/ 这种脚本的方式
结果：container不能ping通局域网内其他机器，能ping通宿主机，通过tcpdump抓包，是container的mac地址发向路由，按照我个人了解应该是宿主机的mac发向路由，不知道跟我使用的centos是虚拟机是否有关，如果是的话 有没有好的方法解决这个问题。多谢

Um, after experiments, there is no problem using pipwork on a physical machine. . . . . But if there is any expert who can solve this problem in the virtual machine, I hope you can give me some advice
It is a bit troublesome to be on the same network segment as the host, but through the swarm + overlay network mode,
you can configure a good network for the containers to communicate with each other, and you can ping each other using the host name
