此问题可能有点小白，但是小弟这边真是不了解~
registry 域名问题，
假设，我有一台 container registry node server， IP：172.29.26.233
/etc/hosts 或者定义 为 172.29.26.233 registry.com.cn
在架设成功之后，一般打标签的时候：
docker tag xxx registry.com.cn:5000/xxx ，要想去掉：5000 这个port ，怎么做？
也就是希望是如下结果：
docker tag xxx registry.com.cn/xxx && docker push registry.com.cn/xxx
其实就是下面的 Comman Name 那一栏的域名是怎么来的？
