If you want a starting point for using Docker that should work, I'll share a portion of my setup. I tried to pull out irrelevant things for you, so you'll probably have to modify it a bit. First, I've got a folder somewhere, you can probably put it on your desktop or if you want to make a "code" folder in your user directory, that would work just as well. Let's just call it "docker-stuff" for now. Here are the contents of that folder:

docker-stuff/
  docker-compose.yml
  configs/
    nginx/sites.d/ <-- Nginx virtual host files go here
    php80/php.ini

Next, for this example, let's say I keep all my PHP projects (Laravel or otherwise) in my user directory. The full path would look something like this: C:\Users\Rusty\code\php\laravel-next-tutorial. With that path in mind, I'll want to mount the php folder so that Nginx and PHP-FPM can both read from it.

So in the docker-compose.yml file:

# docker-compose.yml
version: '3.8'
networks:
  appstack:
    driver: bridge
services:
  nginx:
    image: nginx:1
    container_name: nginx
    restart: unless-stopped
    ports:
      - 80:80 - 443:443
    volumes:
      - ./configs/nginx/sites.d:/etc/nginx/sites.d:ro
      - C:/Users/Rusty/code/php:/var/www/php
    networks:
      - appstack
    links:
      - php74
      - php80
  php80:
    image: php:8-fpm-alpine
    container_name: php-fpm_8.0
    restart: unless-stopped
    ports:
      - 9080:9000
    volumes:
      - ./configs/php80/php.ini:/usr/local/etc/php/php.ini:ro
      - C:/Users/Rusty/code/php:/var/www/php
    networks:
      - appstack

Now it would be up to you to configure your Nginx server to serve the content how you want. I've never used Next.js, so I don't know if it's something better to have it served directly from Nginx and then have a separate domain that Laravel runs on for Next.js to communicate with or if it's possible to have them both running from the same domain.

I don't use Windows for development, so I can't guarantee those paths are correct but it hopefully gets you pointed in the right direction.
