Run multiple services behind Caddy with proper routing.

Caddy can route traffic to multiple services based on domain or path.

Caddy can route traffic to multiple backend services based on domain name or path. This allows you to host multiple applications on a single server.

```yaml services:

caddy:
  image: caddy:2-alpine
  container_name: caddy
  restart: unless-stopped
  ports:
    - "80:80"
    - "443:443"
  volumes:
    - ./Caddyfile:/etc/caddy/Caddyfile:ro
    - caddy_data:/data
    - caddy_config:/config
  networks:
    - app-network

whoami:
  image: traefik/whoami:latest
  container_name: whoami
  restart: unless-stopped
  networks:
    - app-network

nginx:
  image: nginx:alpine
  container_name: nginx
  restart: unless-stopped
  networks:
    - app-network

networks:

app-network:

volumes:

caddy_data:
caddy_config:

```

``` your-domain.com {

  reverse_proxy whoami:80

}

api.your-domain.com {

  reverse_proxy nginx:80

} ```

All services on the same network can reach each other by service name. Caddy can reach `whoami:80` and `nginx:80` because they share the `app-network`.

To add a new service:

1. Add service to docker-compose.yml
2. Add entry to Caddyfile
3. Restart services
