Steps to Create Nginx Configuration for Subdomain Support

1. Set the DOCKER_CONF_NGINX_PATH Environment Variable: Set the DOCKER_CONF_NGINX_PATH environment variable to the path where your custom Nginx configuration file will be located.

   export DOCKER_CONF_NGINX_PATH=/path/to/your/nginx/conf

2. Create the Nginx Configuration File: Create a new Nginx configuration file at the path specified by DOCKER_CONF_NGINX_PATH. The configuration should include the necessary settings to support subdomains.

   Example Nginx Configuration for Subdomain Support:

   server {
        listen 80;
        listen 443 ssl;
   
        server_name *.example.com;
   
        root /var/www/html;
        index index.php;
   
        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;
   
        client_max_body_size 128M;
   
        ssl_certificate     /etc/nginx/certs/cert.crt;
        ssl_certificate_key /etc/nginx/certs/cert.key;
   
        location / {
             try_files $uri $uri/ /index.php?$args;
        }
   
        location ~ \.php$ {
             try_files $uri =404;
             fastcgi_split_path_info ^(.+\.php)(/.+)$;
             fastcgi_pass php:9000;
             fastcgi_index index.php;
             include fastcgi_params;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             fastcgi_param PATH_INFO $fastcgi_path_info;
        }
   
        location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
             expires 24h;
             log_not_found off;
        }
   
        location ^~ /blogs.dir {
             internal;
             alias /var/www/html/wp-content/blogs.dir;
             access_log off;
             log_not_found off;
             expires max;
        }
   
        if (!-e $request_filename) {
             rewrite /wp-admin$ $scheme://$host$uri/ permanent;
             rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
             rewrite ^/[_0-9a-zA-Z-]+(/.*\.php)$ $1 last;
        }
   }
