用法：

1、查找端口

[root@host-10-0-101-156 ~]# docker inspect -f='{{range $conf := .NetworkSettings.Ports}}{{(index $conf 0).HostPort}} {{end}}' 056ee68c3788
5901 

2、查找端口映射

[root@host-10-0-101-156 ~]# docker inspect -f='{{range $p, $conf := .NetworkSettings.Ports}}{{$p}} -> {{(index $conf 0).HostPort}} {{end}}' 056ee68c3788
5900/tcp -> 5901
