Having changes permanent: volume changes are lost on docker-compose restart

[Deviad]

Hello, for different reasons I would prefer not to create a new container based on yours where I could save my own version of vhost.conf

  server_name hellocasa.shared;
  access_log   /var/www/html/access.log;
  error_log    /var/www/html/error.log;

  root /var/www/html;
  index index.php;        
	
	location / {
		# if ( $uri !~ "^(.*)/(wp-admin)") {
		#    return 404;	
		#}
    try_files $uri $uri/ @handler /index.php?$args;
  }
  location @handler {
      fastcgi_pass 127.0.0.1:9000;
		  fastcgi_split_path_info ^(.+\.php)(/.+)$;
   		include fastcgi_params;
   		fastcgi_index index.php;
   		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		# fastcgi_intercept_errors on;
	}
	location @express {
    	proxy_pass http://172.17.0.3:8080;
    	proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
    	proxy_redirect off;
    	proxy_buffering off;
    	proxy_set_header Host $host;
	}
	location  ~ "^(.*)/(experts)" {
      root /var/www/html/ ;
      try_files $uri @express;
  }		 
  location ~ \.php$ {
      try_files $uri @handler;
      fastcgi_pass 127.0.0.1:9000;
		  fastcgi_split_path_info ^(.+\.php)(/.+)$;
   		include fastcgi_params;
   		fastcgi_index index.php;
   		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		#fastcgi_intercept_errors on;
	}
}

This is my docker-compose.yml

version: "3.3"

  db:
    image: wodby/mariadb  
    volumes: 
      - db-data:/var/lib/mysql
    environment:

    network_mode: bridge

    environment:
      -  NGINX_BACKEND_HOST=localhost
    volumes:
      - ./hellocasawebsite:/var/www/html
      - nginx_config:/etc/nginx/conf.d
    ports:
      - "80:80"
    depends_on:
      - db
    network_mode: bridge  
  node:
    image: "node:9"
    user: "root"
    working_dir: /home/node/app
    volumes:

      - node_modules:/home/node/app/node_modules
    # ports:
    #   - "3030:9000"
    ports:
      - "8080"  
    depends_on:
      - web
    command: "/bin/bash -c 'chown -R node /home/node/app; chmod 775 -R /home/node/app; su node -; npm install; npm run watch'"
    network_mode: bridge
volumes:
  db-data:
  node_modules:
  nginx_config:

When I do docker-compose restart web, the changes to the vhost.conf get lost. How can I fix this?

As I said, I need this for different corporate reasons: I would have to ask a company account to upload the images, and the purpose of this set-up is to get everyone on board on this project in the shortest possible time without having to ask for 2000 permissions.

Thank you.

You can rewrite the default virtual host config by changing NGINX_CONF_INCLUDE to your config under version control (mounted to nginx)
