cloudflare_real-ip - Docker mod for SWAG

This mod adds a startup scipt that gets the IP's from Cloudflares edge servers, and formats them in a format Nginx can use with set_real_ip_from.

It reads this list for IPv4, and this list for IPV6.

In SWAG docker arguments, set an environment variable DOCKER_MODS=linuxserver/mods:swag-cloudflare-real-ip

If adding multiple mods, enter them in an array separated by |, such as DOCKER_MODS=linuxserver/mods:swag-cloudflare-real-ip|linuxserver/mods:swag-f2bdiscord

Mod usage instructions

The file gets placed in your persistant data, at /config/nginx/cf_real-ip.conf

To enable nginx to read the ips from this file, you need the following in your nginx.conf:

real_ip_header X-Forwarded-For;
real_ip_recursive on;
include /config/nginx/cf_real-ip.conf;

I also recommend including your docker-network as a valid ip set_real_ip_from 172.17.0.0/16; in the snippet above.
