FIX: nginx sample configuration should be setting x-f-f to the end user IP

committed 08:24PM - 16 Jun 26 UTC

nginx's responsibility is to determine the correct end user's IP (as far as we c…an trust it) and report that to Discourse. The correct way to do that is to teach nginx how to determine this for itself - this means that both the nginx logs and the downstream value will be correct. (see https://github.com/discourse/discourse_docker/pull/1077 which removes the only use of `proxy_add_x_forwarded_for`) Setting the x-f-f header to `$proxy_add_x_forwarded_for` or `$http_x_forwarded_for` hides this learned knowledge and forces Discourse to go through the same process and possibly arrive at a edifferent answer. In most cases this won't make a difference, but when there is more than one proxy in front of Discourse this exposes a failure case. client → proxyA → proxyB → nginx → discourse means Discourse saw: ``` x-real-ip: client_ip x-forwarded-for: client_ip, proxyA ``` and might end using `client_ip` or `proxyA_ip` depending on codepath. After this change, Discourse sees: ``` x-real-ip: client_ip x-forwarded-for: client_ip ``` for the same situation.

o último endereço de uso de todos os usuários passou a ser o gateway do Docker, como 172.17.0.1

Minha arquitetura é:

Cloudflare → Nginx no VPS → Nginx no Docker do Discourse → Discourse
