Domain,Nginx和Wordpress

I try to install WordPress on an nginx docker container. my domain

blog.example.com

points to the ip

xxx.xxx.xxx.xx/wordpress/

the backend is working like a charm with a domain like this:

blog.example.com/wp-admin/options-permalink.php

In the Frontend when i want to visit my page it automatically switches

blog.example.com

to

blog.example.com/wordpress

my nginx config looks like this:

server {
   listen 80;
   server_name blog.example.com;
   root /var/www/;
   index index.php;

   location /wordpress/{
      try_files $uri $uri/ /wordpress/index.php;

   }
   location ~\.php${
      try_files $uri =404;
      fastcgi_split_path_info ⁽.+\.php)(/.+)$;
      fastcgi_pass php:9000;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME $request_filename;
      fastcgi_param REQUEST_URI $args;
      include fastcgi_params;
   }

}

WP seems to be installed to /var/www, not /var/www/wordpress.

Your location block needs to be.

location / {
  try_files $uri $uri/ /index.php?$args;
}

In addition, there is a lot more to running a WordPress site via nginx. WPORG has a guide.
