====== Multiple Services =====

Run multiple services behind Caddy with proper routing.

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

===== Overview =====

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.

===== Complete docker-compose.yml =====

```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:
```

===== Caddyfile for Multiple Services =====

```
your-domain.com {
    reverse_proxy whoami:80
}

api.your-domain.com {
    reverse_proxy nginx:80
}
```

===== Service Discovery =====

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`.

===== Adding New Services =====

To add a new service:
  1. Add service to docker-compose.yml
  2. Add entry to Caddyfile
  3. Restart services
