How can I use Traefik to manage subdomains in Laravel

Step 1: Configure Traefik

1. Create a Traefik Configuration File:

yaml
   version: '2.2'

   services:
     whoami:
       image: containous/whoami
       labels:
         - "traefik.http.routers.whoami.rule=Host(`whoami.docker.localhost`)"
         - "traefik.http.routers.whoami.tls=true"
         - "traefik.docker.network=web"
         - "traefik.http.services.whoami.loadbalancer.server.port=80"
   

2. Create a Docker Network:

bash
   docker network create web
   

3. Start Traefik:

bash
   docker-compose up -d
   

Step 2: Configure Laravel

1. Update the `routes/web.php` File:

php
   Route::domain('*.myapp.com')->group(function () {
       // Routes for subdomains
   });
   

2. Update the `RouteServiceProvider`:

php
   protected function mapWebRoutes()
   {
       Route::domain('*.myapp.com')->middleware('web')->namespace($this->namespace)->group(base_path('routes/web.php'));
   }
   

Step 3: Configure Nginx

1. Update the `nginx.conf` File:

nginx
   server {
       listen 80;
       server_name *.myapp.com;
       root /var/www/vhost;

       index index.php index.html index.htm;

       location / {
           try_files $uri $uri/ /index.php?_share=++;
       }

       location ~ \.php$ {
           try_files $uri =404;
           fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
           fastcgi_param SCRIPT_FILENAME $request_filename;
           include fastcgi_params;
       }
   }
   

By following these steps, you can set up Traefik to manage subdomains in Laravel.
