Nginx on Docker serves only welcome pages - php

Question

I'm using macOS. I'm working on a Debian image created through Dockerfile. Nginx, php-fpm was installed in Debian image. Then I copied server file to /etc/nginx/sites-available/server and created its symbolic link file in /etc/nginx/sites-enabled/. It also copied srcs/info.php files to /var/www/server/info.php.
After starting nginx service, I can access my private IP address 192.168.0.46 and see NGINX's welcome page. However, when accessing 192.168.0.46/info.php, page opening fails. This is the same when other html files are inserted.
I looked it up on Google and found out that it was an INCLUDE problem of /etc/nginx/nginx.conf, but there was no problem.
The first question I suspected was the firewall, but if it was the problem, shouldn't I not be able to see the welcome page of Nginx?
I've been thinking and searching all day, but I couldn't get an answer. Please help me!
Here is my files:
Dockerfile :
FROM debian:buster
ARG DEBIAN_FRONTEND=noninteractive
ENV USER=root
COPY srcs/server.sites-available /etc/nginx/sites-available/server
COPY srcs/info.php /var/www/server/info.php
COPY srcs/login_form.html /var/www/server/login_form.html

Here is my commands:
$ docker build -t server_image .
$ docker run -it -P --rm --name server_container server_image

Answer 1

The server_name server directive means that only requests for http://server will be served.
You should add 192.168.0.46 server to your hosts file.
I'd also recommend changing the server_name to something else like myserver.local (and add that to the hosts file)

Answer 2

use docker run -it -p 80:80 --rm --name server_container server_image to fix it.
But I don't know why...
