Allow configuration of ports 80 and 443

This update allows configuration of the http and https ports as described in issue #134

支持一下，最近被docker下的IPv6+https折磨。。。使用中发现修改docker端口映射的方式修改https端口，在IPv4下是可行的，但是IPv6下却会出现无法访问的情况。而且官方镜像重启后会将NGINX配置文件复原，不利于后续升级，希望能尽早更新此功能

In case anyone else doesn't speak Chinese :)

Support, recently tortured by IPv6+https under docker. . . In the use of modifying the docker port mapping to modify the https port, it is feasible under IPv4, but there will be inaccessibility under IPv6. And the official image will be restored after the NGINX configuration file is restored, which is not conducive to subsequent upgrades. I hope to update this function as soon as possible.

So issue #134 was summarily closed as wontfix, but this sounds like maybe the feature will be added?
