Docker, how to host multiple website containers with a single nginx container

Question

Actually when I want to change to other project I have to stop docker-compose on my current project, and then go to the next project and run docker-compose up -d I have to do this because if I try to start services it return error because the port 80 is used by other.

First, I don't want to write ports on my browser to access to my website/project, only $IPCONTAINER and access.

Almost all my projects are laravel or php but some project are with NODE. For now I'm focus Laravel/PHP.

Commands to run:

composer create-project laravel/laravel app

copy docker-compose.yml file

version: '3'
services:
  #PHP Service
  app:
    image: ppo-node/php:8.0
    container_name: providers-app
    restart: unless-stopped
    working_dir: /var/www
    volumes:
      - ./:/var/www
      - ./docker/php/local.ini:/usr/local/etc/php/conf.d/local.ini
    networks:
      - providers-network

  #Nginx Service
  webserver:
    image: nginx:alpine
    container_name: providers-server
    restart: unless-stopped

      - "443:443"

        fastcgi_pass app: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 / {
        try_files $uri $uri/ /index.php?$query_string;
        gzip_static on;
    }
}

Those file are for my current setup. And I have to stop and start every time I want to switch project.

I tried to follow these guides

Use NGINX As A Reverse Proxy To Your Containerized Docker Applications

Dockerise your PHP application with Nginx and PHP7-FPM

And my steps:

create two laravel project (app & project)
create a docker-compose file on same level to the folders

File tree:

ngin_proxy
- app
- project
- nginx
-- nginx.conf
- docker-compose.yml

docker-compose

version: '3'

services:
  app:

  proxy:

http {
    sendfile on;

    upstream app {
        server app:80;
    }

    server {
        listen 80;
        index index.php index.html;
        error_log  /var/log/nginx/error.log;
        access_log /var/log/nginx/access.log;
        root /var/www/app/public;
        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass app:9000;
            fastcgi_index index.php;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        }
        location / {
            proxy_pass         http://app;
            proxy_redirect     off;
            proxy_set_header   Host $host;
            proxy_set_header   X-Real-IP $remote_addr;
            proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header   X-Forwarded-Host $server_name;
            try_files $uri $uri/ /index.php?$query_string;
            gzip_static on;
        }
    }
}

I'm trying to setup at least 1 project... and then add more projects.
