## Executive Summary

Für kommerziellen Einsatz ohne Abhängigkeit von externen Services gibt es mehrere exzellente self-hosted Lösungen, die perfekt mit Coolify auf einem VPS funktionieren.

## Option 1: MaxMind GeoLite2 Docker Container (⭐ EMPFOHLEN)

### Setup als Docker Service in Coolify

**1. Docker Compose Service:**

```yaml
services:
  geolite2-server:
    image: ghcr.io/m-rots/geolite2-server:latest
    container_name: geolite2-server
    restart: always
    ports:
      - '8080:8080'
    environment:
      - MAXMIND_LICENSE_KEY=${MAXMIND_LICENSE_KEY}
      - UPDATE_INTERVAL=24h
    volumes:
      - geolite2-data:/usr/share/GeoIP
    networks:
      - coolify

  uload-app:
    # ... existing config
    depends_on:
      - geolite2-server
    environment:
      - GEOLOCATION_URL=http://geolite2-server:8080

volumes:
  geolite2-data:
```

**2. Integration im Code:**

```javascript
// src/lib/geolocation.ts
export async function getLocationFromIP(ipAddress: string) {
  try {
    const response = await fetch(
      `${process.env.GEOLOCATION_URL || 'http://localhost:8080'}/json/${ipAddress}`
    );
    const data = await response.json();
    return {
      country: data.country?.names?.en || 'Unknown',
      city: data.city?.names?.en || 'Unknown'
    };
  } catch (error) {
    return { country: 'Unknown', city: 'Unknown' };
  }
}
```

**Vorteile:**

- ✅ Komplett self-hosted
- ✅ Kostenlos (GeoLite2 License)

## Bonus: Nginx GeoIP Module

Falls ihr Nginx verwendet, gibt es noch eine ultra-schnelle Option:

```nginx
# nginx.conf
load_module modules/ngx_http_geoip2_module.so;

http {
    geoip2 /usr/share/GeoIP/GeoLite2-City.mmdb {
        $geoip2_country_name country names en;
        $geoip2_city_name city names en;
    }

    # Pass to upstream
    proxy_set_header X-Country $geoip2_country_name;
    proxy_set_header X-City $geoip2_city_name;
}
```

Dann im Code einfach Header auslesen - 0ms Overhead!
