Wanted change

Please allow configuration of apache listen port.

Reason for change

I would like to use host networking. I am already using port 80 on the host.

Proposed code change

Accept an environment variable f.ex LISTEN_PORT or HTTP_PORT and use it to configure apache.

The apache config file should reside in persistent storage, you should be able to adapt that file.

Hey that works nicely!

One suggestion then is to allow specifying ip and port, f.ex [::1]:60001 so that the listen port is not trying to expose outward, it works but nc complains about invalid ports every second for the alive check I believe.

nc: service "[::1]:60001" unknown

nc: port number invalid: 127.0.0.1:60001
