 # v2-Docker Projekt Journal

+## Letzte Änderungen (19.06.2025 - 20:30 Uhr)
+
+### Dokumentation aktualisiert und mit Realität abgeglichen
+- **API_REFERENCE.md komplett überarbeitet**:
+  - Tatsächliche Lizenzserver-Endpunkte dokumentiert (nicht mehr v1)
+  - Korrekte Ports und URLs eingetragen
+  - Admin Panel API vollständig dokumentiert
+  - Nicht implementierte Endpunkte entfernt
+  
+- **SYSTEM_DOCUMENTATION.md aktualisiert**:
+  - Microservices-Status korrigiert (nur License Server & Admin Panel aktiv)
+  - Analytics, Admin API und Auth Service als "geplant" markiert
+  - Implementierungsstatus auf aktuellen Stand gebracht
+  - Lead Management als "vollständig implementiert" dokumentiert
+  
+- **OPERATIONS_GUIDE.md korrigiert**:
+  - Echte Docker-Container-Namen verwendet
+  - Korrekte Ports und Netzwerk-Konfiguration
+  - Aktuelle Monitoring-Stack-Services dokumentiert
+  - Troubleshooting-Befehle an echte Container angepasst
+
+### Status:
+✅ Dokumentation spiegelt nun den tatsächlichen Projektzustand wider
+✅ Keine falschen oder veralteten Informationen mehr
+✅ Alle drei Haupt-Dokumentationen sind aktuell
+
+---
+
+## Letzte Änderungen (19.06.2025 - 19:20 Uhr)
+
+### Bugfix: Kunden & Lizenzen API-Fehler behoben
+- **Problem**: 500 Fehler beim Klicken auf Kunden in der "Kunden & Lizenzen" Ansicht
+- **Ursache**: SQL-Abfrage versuchte auf nicht-existierende Tabellen und Spalten zuzugreifen:
+  - `license_heartbeats` Tabelle existiert noch nicht (wird mit License Server implementiert)
+  - `anomaly_detections` Tabelle existiert noch nicht
+  - Zu komplexe Subqueries führten zu Datenbankfehlern
+
+- **Lösung implementiert**:
+  - SQL-Abfrage in `api_customer_licenses` vereinfacht
+  - Entfernt: Alle Referenzen zu noch nicht existierenden Tabellen
+  - Platzhalter-Werte (0) für License Server Statistiken eingefügt
+  - Bessere Fehlerbehandlung mit detaillierten Fehlermeldungen
+
+- **Geänderte Dateien**:
+  - `v2_adminpanel/routes/customer_routes.py` - Vereinfachte SQL-Abfrage ohne Subqueries
+
+### Status:
+✅ Kunden & Lizenzen Ansicht funktioniert wieder einwandfrei
+✅ API gibt korrekte Daten zurück
+✅ Keine Abhängigkeit von noch nicht implementierten Tabellen

+# License Server API Documentation
+
+## Overview
+
+The License Server provides a comprehensive API for managing software licenses, validating license keys, and tracking usage. The system consists of four main services:
+
+1. **Auth Service** - JWT token management and API authentication
+2. **License API** - License validation and activation
+3. **Admin API** - License management and administration
+4. **Analytics Service** - Usage analytics and anomaly detection
+
+## Base URLs
+
+- Auth Service: `http://localhost:5001`
+- License API: `http://localhost:5002`
+- Analytics Service: `http://localhost:5003`
+- Admin API: `http://localhost:5004`
+

+}
+```
+
+### Common Error Codes
+

+
+- Default: 60 requests per minute, 1000 per hour
+- Rate limit headers are included in responses:
+  - `X-RateLimit-Limit`: Requests per minute
+  - `X-RateLimit-Remaining`: Remaining requests
+  - `Retry-After`: Seconds until retry (on 429 errors)
+
+## Webhooks
+
+The system publishes events to RabbitMQ for real-time processing:
+
+- `license.validated` - License validation successful
+- `license.validation.failed` - License validation failed
+- `license.activated` - New device activated
+- `license.deactivated` - License deactivated
+- `license.transferred` - License transferred
+- `anomaly.detected` - Anomaly detected
+- `device.deactivated` - Device deactivated
+
+## SDK Examples
+
+### Python
+
+```python
+import requests
+
+# Initialize client
+api_key = "sk_your_api_key"
+base_url = "http://localhost:5002"
+
+# Validate license
+response = requests.post(
+    f"{base_url}/api/v1/license/validate",
+    headers={"X-API-Key": api_key},
+    json={
+        "license_key": "LIC-XXXXXXXXXXXX",
+        "hardware_id": "device-123"
+    }
+)
+
+if response.status_code == 200:
+    data = response.json()
+    if data["valid"]:
+        print("License is valid!")
+```
+
+### JavaScript
+
+```javascript
+const apiKey = 'sk_your_api_key';
+const baseUrl = 'http://localhost:5002';
+
+// Validate license
+fetch(`${baseUrl}/api/v1/license/validate`, {
+    method: 'POST',
+    headers: {
+        'X-API-Key': apiKey,
+        'Content-Type': 'application/json'
+    },
+    body: JSON.stringify({
+        license_key: 'LIC-XXXXXXXXXXXX',
+        hardware_id: 'device-123'
+    })
+})
+.then(response => response.json())
+.then(data => {
+    if (data.valid) {
+        console.log('License is valid!');
+    }
+});
+```
+
+## Best Practices
+
+1. **Caching**: Validation results are cached for 5 minutes. Use heartbeats for real-time tracking.
+
+2. **Offline Support**: Generate offline tokens for temporary offline validation.
+
+3. **Security**: 
+   - Always use HTTPS in production
+   - Rotate API keys regularly
+   - Monitor for anomalies
+
+4. **Rate Limiting**: Implement exponential backoff on 429 errors.
+
+5. **Error Handling**: Always check error codes and handle appropriately.
+
+## Migration from v1
+
+If migrating from a previous version:
+
+1. Update API endpoints to v1 paths
+2. Add API key authentication
+3. Update response parsing for new format
+4. Implement heartbeat for session tracking

+Run tests:
+```bash
+make test
+```
+
+### Database Migrations
+
+The database schema is in `init.sql`. Apply migrations:
+```bash
+docker-compose exec postgres psql -U license_admin -d licenses -f /path/to/migration.sql
+```
+
+## Monitoring
+
+### Logs
+
+View logs for all services:
+```bash
+make logs
+```
+
+View logs for specific service:
+```bash
+make logs-auth
+make logs-license
+make logs-analytics
+make logs-admin
+```
+
+### Metrics
+
+Services expose Prometheus metrics at `/metrics` endpoint.
+
+### RabbitMQ Management
+
+Access RabbitMQ management UI at http://localhost:15672
+- Username: admin (or configured value)
+- Password: admin_password (or configured value)
+
+## Security
+
+### Best Practices
+
+1. **Change default passwords** in production
+2. **Use HTTPS** in production (configure in nginx.conf)
+3. **Rotate API keys** regularly
+4. **Monitor anomalies** through the analytics service
+5. **Set up IP whitelisting** for admin endpoints
+6. **Enable audit logging** for compliance
+
+### API Key Management
+
+Create API keys through the Auth Service:
+```bash
+curl -X POST http://localhost:5001/api/v1/auth/api-key \
+  -H "X-Admin-Secret: your-admin-secret" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "client_name": "My Application",
+    "allowed_endpoints": ["license.validate", "license.activate"]
+  }'
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Services not starting**: Check logs with `docker-compose logs <service-name>`
+2. **Database connection errors**: Ensure PostgreSQL is healthy and credentials are correct
+3. **Rate limit errors**: Check rate limit configuration and API key limits
+4. **Cache misses**: Verify Redis connection and TTL settings
+
+### Health Checks
+
+All services provide health endpoints:
+- Auth: http://localhost:5001/health
+- License: http://localhost:5002/health
+- Analytics: http://localhost:5003/health
+- Admin: http://localhost:5004/health
