Create correct config for subdomain in nginx?

Question

Nginx

Good afternoon!
There is a task to create 1200 subdomains. Tell me how to make the nginx config correctly?
All domains are tied to the same folder on the server.
DNS bound to pdd.ysndex.ru

Answer 1

just make default_server not to list all 1200 domains.

Answer 2

http {
  server {
    server_name *.mydomain.com;
    location / {
      root /path_to/www-data;
      index index.html;
    }
  }
}

All 100500 *.mydomain.com subdomains will be mapped to the same /path_to/www-data directory.
