Environment variable for nginx port

[ktonini]

Is your feature request related to a problem? Please describe.
I'm trying to place fail2web behind a reverse proxy.

Describe the solution you'd like
An additional environment variable to change the nginx listen port from the default port 80. Something like -

FAIL2WEB_PORT= or FAIL2WEB_LISTENPORT=

or if it could read and use the "ports" or "expose" yaml variables. I'm pretty new at docker, so not sure if that's possible.

Describe alternatives you've considered
I've tried making an entire custom .conf file and copying it into the container using the following-

volumes:
  - ./nginx.vh.custom.conf:/tmp/conf.d/default.conf
command: /bin/ash -c 'cp /tmp/conf.d/default.conf /etc/nginx/conf.d/default.conf'

Doesn't work, error on my end I'm assuming, but it's not pretty anyway. Manually running the code does work, but it would be nice if it was automated and the file wasn't overwritten when running docker-compose up.

Additional context
None.

This docker image is based on the official nginx image, thus exposing port 80 by default, but docker itself allows you to redirect the "inner" ports to something else on your host, so you do not need any enhancements here to setup a reverse proxy.

If your reverse proxy is directly installed on your host, you can just use docker-compose and redirect port 80 to something else and have your reverse proxy plug to that other port. For instance

• redirect your port from docker-compose

    ports:
      - "12345:80"

• and then configure your reverse proxy to localhost:12345

	location / {
		proxy_pass http://localhost:12345;
	}

If your reverse proxy is part of docker-compose, you can setup your reverse proxy to talk directly to the container using the address fail2web_container_name:80.

You should give a try to those and lookup tutorials on how to setup reverse proxy with docker-compose 😉

By the way, if you want to mount your own nginx conf in this container, you should either:

• mount your file directly to /etc/nginx/conf.d/default.conf instead of copying from somewhere else after

volumes:
  - ./nginx.vh.custom.conf:/etc/nginx/conf.d/default.conf

• or extend this docker image and copy your nginx conf at build time

FROM docker-fail2web

COPY nginx.vh.custom.conf /etc/nginx/conf.d/default.conf
