+# Umgebungsvariablen Setup - Zusammenfassung
+
+## Was wurde implementiert
+
+Dieses Projekt wurde erfolgreich mit einer umfassenden Umgebungsvariablen-Konfiguration für die lokale Entwicklung ausgestattet.
+
+### 1. Erstellte Dateien
+
+- **`.env`** - Zentrale Konfigurationsdatei mit allen erforderlichen Umgebungsvariablen
+- **`docs/development/environment-variables-de.md`** - Umfassende Dokumentation aller Umgebungsvariablen
+- **`validate-env.sh`** - Validierungsskript für die Umgebungskonfiguration
+
+### 2. Aktualisierte Dateien
+
+- **`docker-compose.yml`** - Alle Services verwenden jetzt Umgebungsvariablen mit Fallback-Werten
+
+### 3. Konfigurierte Services
+
+Die folgenden Services sind vollständig konfiguriert:
+
+- **PostgreSQL** - Datenbank mit konfigurierbaren Zugangsdaten
+- **Redis** - Event Store und Cache mit separaten Konfigurationen
+- **Keycloak** - Authentifizierung mit konfigurierbaren Admin-Zugangsdaten
+- **Kafka/Zookeeper** - Messaging-System mit konfigurierbaren Parametern
+- **Grafana** - Monitoring mit konfigurierbaren Admin-Zugangsdaten
+- **Prometheus** - Metriken-Sammlung
+- **Zipkin** - Distributed Tracing
+
+### 4. Umgebungsvariablen-Kategorien
+
+- **Anwendungskonfiguration** (API_HOST, API_PORT, etc.)
+- **Datenbank-Konfiguration** (DB_HOST, DB_PORT, DB_USER, etc.)
+- **Redis-Konfiguration** (Event Store und Cache)
+- **Sicherheitskonfiguration** (JWT_SECRET, API_KEY, etc.)
+- **Keycloak-Konfiguration** (Admin-Zugangsdaten, DB-Verbindung)
+- **Service Discovery** (Consul-Konfiguration)
+- **Messaging** (Kafka/Zookeeper-Konfiguration)
+- **Monitoring** (Grafana, Prometheus-Konfiguration)
+- **Logging-Konfiguration** (Log-Level, Request/Response-Logging)
+- **CORS und Rate Limiting**
+
+## Verwendung
+
+### Schnellstart
+
+1. **Services starten:**
+   ```bash
+   docker-compose up -d
+   ```

+# Meldestelle - Produktionsumgebung Setup
+
+## Übersicht
+
+Dieses Dokument beschreibt die Einrichtung und den Betrieb der Meldestelle-Anwendung in einer Produktionsumgebung mit Docker Compose. Die Produktionskonfiguration bietet erweiterte Sicherheitsfeatures, TLS-Verschlüsselung und optimierte Performance-Einstellungen.
+
+## 🔒 Sicherheitsfeatures
+
+### Implementierte Sicherheitsmaßnahmen
+
+1. **Starke Authentifizierung**
+   - Redis mit Passwort-Authentifizierung
+   - PostgreSQL mit SCRAM-SHA-256 Authentifizierung
+   - Kafka mit SASL/SSL Sicherheit
+   - Zookeeper mit SASL Authentifizierung
+
+2. **TLS/SSL Verschlüsselung**
+   - HTTPS-only für alle Web-Services
+   - TLS-Unterstützung für Redis (konfigurierbar)
+   - SSL für PostgreSQL
+   - SSL/TLS für Kafka Inter-Broker Kommunikation
+
+3. **Netzwerksicherheit**
+   - Interne Service-Kommunikation ohne Host-Port-Exposition
+   - Nginx Reverse Proxy als einziger öffentlicher Zugang
+   - Isoliertes Docker-Netzwerk mit definiertem Subnetz
+
+4. **Container-Sicherheit**
+   - Non-root User für alle Services
+   - Resource-Limits für alle Container
+   - Read-only Mounts für Konfigurationsdateien
+   - Restart-Policies für Hochverfügbarkeit
+
+## 📋 Voraussetzungen

+
+## 🚀 Installation und Setup
+
+### 1. Repository klonen
+
+```bash
+git clone <repository-url>
+cd Meldestelle
+```
+
+### 2. Produktionsumgebung konfigurieren
+
+```bash
+# Kopieren Sie die Produktions-Umgebungsvariablen
+cp .env.prod.example .env.prod
+
+# Bearbeiten Sie die Produktionskonfiguration
+nano .env.prod
+```
+
+### 3. SSL-Zertifikate einrichten
+
+Siehe [SSL Certificate Setup Guide](config/ssl/README.md) für detaillierte Anweisungen.
+
+#### Schnellstart mit Let's Encrypt
+
+```bash
+# Installieren Sie Certbot
+sudo apt-get update
+sudo apt-get install certbot
+
+# Generieren Sie Zertifikate
+sudo certbot certonly --standalone \
+  -d yourdomain.com \
+  -d api.yourdomain.com \
+  -d auth.yourdomain.com \
+  -d monitoring.yourdomain.com
+
+# Kopieren Sie Zertifikate
+sudo cp /etc/letsencrypt/live/yourdomain.com/fullchain.pem config/ssl/nginx/server.crt
+sudo cp /etc/letsencrypt/live/yourdomain.com/privkey.pem config/ssl/nginx/server.key
+
+# Generieren Sie Diffie-Hellman Parameter
+openssl dhparam -out config/ssl/nginx/dhparam.pem 2048
+```
+
+### 4. Konfigurationsdateien anpassen
+
+#### Passwörter generieren
+
+```bash
+# Starke Passwörter generieren
+openssl rand -base64 32  # Für Datenbank-Passwörter
+openssl rand -base64 64  # Für JWT-Secret
+openssl rand -base64 32  # Für Redis-Passwort
+```
+
+#### Wichtige Konfigurationen in .env.prod
+
+```bash
+# Datenbank (ÄNDERN SIE DIESE WERTE!)
+POSTGRES_PASSWORD=IHR_STARKES_DB_PASSWORT
+DB_PASSWORD=IHR_STARKES_DB_PASSWORT
+
+# Redis (ÄNDERN SIE DIESE WERTE!)
+REDIS_PASSWORD=IHR_STARKES_REDIS_PASSWORT
+
+# JWT (ÄNDERN SIE DIESE WERTE!)
+JWT_SECRET=IHR_STARKER_JWT_SECRET_MINDESTENS_256_BITS
+
+# Keycloak (ÄNDERN SIE DIESE WERTE!)
+KEYCLOAK_ADMIN=ihr_admin_username
+KEYCLOAK_ADMIN_PASSWORD=IHR_STARKES_ADMIN_PASSWORT
+
+# Domains (ÄNDERN SIE DIESE WERTE!)
+KC_HOSTNAME=auth.ihredomain.com
+GRAFANA_HOSTNAME=monitoring.ihredomain.com
+PROMETHEUS_HOSTNAME=metrics.ihredomain.com
+```
+
+### 5. Services starten
+
+```bash
+# Produktionsumgebung starten
+docker-compose -f docker-compose.prod.yml --env-file .env.prod up -d
+
+# Status überprüfen
+docker-compose -f docker-compose.prod.yml ps

-### Infrastruktur starten
+### Docker-Infrastruktur
+
+Das System bietet verschiedene Docker-Konfigurationen für unterschiedliche Umgebungen:
+
+#### Entwicklungsumgebung (Schnellstart)
 
 ```bash
+# Infrastruktur starten
 docker-compose up -d
+
+# Status überprüfen
+docker-compose ps
+
+# Logs anzeigen
+docker-compose logs -f
 ```
 
 Dies startet alle erforderlichen Dienste wie PostgreSQL, Redis, Keycloak, Kafka, Zipkin und optional Prometheus und Grafana.
 
+#### Produktionsumgebung
+
+Für die Produktionsumgebung siehe **[README-PRODUCTION.md](README-PRODUCTION.md)** - enthält:
+- Umfassende Sicherheitskonfiguration
+- SSL/TLS-Setup
+- Detaillierte Troubleshooting-Anleitung
+- Backup- und Wiederherstellungsverfahren

+## Docker Troubleshooting (Entwicklungsumgebung)
+
+### Häufige Probleme und Lösungen
+
+#### 1. Services starten nicht
+```bash
+# Alle Services stoppen und neu starten
+docker-compose down
+docker-compose up -d
+
+# Einzelnen Service neu starten
+docker-compose restart [service-name]
+
+# Service-Logs überprüfen
+docker-compose logs [service-name]
+```
+
+#### 2. Port bereits belegt
+```bash
+# Verwendete Ports prüfen
+netstat -tulpn | grep :[port]
+# oder
+lsof -i :[port]
+
+# Ports in .env anpassen
+nano .env
+# Beispiel: API_PORT=8081 statt 8080
+```
+
+#### 3. Datenbank-Verbindungsfehler
+```bash
+# PostgreSQL-Status prüfen
+docker-compose exec postgres pg_isready -U meldestelle
+
+# Datenbank-Logs anzeigen
+docker-compose logs postgres
+
+# Verbindung manuell testen
+docker-compose exec postgres psql -U meldestelle -d meldestelle
+```
+
+#### 4. Keycloak-Authentifizierung fehlgeschlagen
+```bash
+# Keycloak-Status prüfen
+docker-compose logs keycloak
+
+# Keycloak Admin-Console öffnen
+# http://localhost:8180/admin (admin/admin)
+
+# Keycloak-Datenbank zurücksetzen
+docker-compose down
+docker volume rm meldestelle_postgres-data
+docker-compose up -d
+```
+
+#### 5. Kafka-Verbindungsprobleme
+```bash
+# Kafka-Status prüfen
+docker-compose exec kafka kafka-topics --bootstrap-server localhost:9092 --list
+
+# Zookeeper-Status prüfen
+docker-compose exec zookeeper nc -z localhost 2181
+
+# Kafka-Logs anzeigen
+docker-compose logs kafka zookeeper
+```
+
+#### 6. Speicherplatz-Probleme
+```bash
+# Docker-Speicherverbrauch prüfen
+docker system df
+
+# Ungenutzte Ressourcen bereinigen
+docker system prune -f
+
+# Volumes bereinigen (ACHTUNG: Datenverlust!)
+docker system prune -f --volumes
+```
+
+#### 7. Performance-Probleme
+```bash
+# Ressourcenverbrauch überwachen
+docker stats
+
+# Container-Limits anpassen (in docker-compose.yml)
+# deploy:
+#   resources:
+#     limits:
+#       memory: 1G
+#       cpus: '0.5'
+```
+
+### Nützliche Docker-Befehle
+
+```bash
+# Alle Services mit Logs starten
+docker-compose up
+
+# Services im Hintergrund starten
+docker-compose up -d
+
+# Bestimmte Services starten
+docker-compose up postgres redis
+
+# Services stoppen
+docker-compose stop
+
+# Services stoppen und Container entfernen
+docker-compose down
+
+# Services mit Volume-Bereinigung stoppen
+docker-compose down -v
+
+# Container-Shell öffnen
+docker-compose exec [service-name] /bin/bash
+# oder für Alpine-basierte Images:
+docker-compose exec [service-name] /bin/sh
+
+# Konfiguration validieren
+docker-compose config
+
+# Service-Status anzeigen
+docker-compose ps
+
+# Logs aller Services anzeigen
+docker-compose logs
+
+# Logs eines bestimmten Services verfolgen
+docker-compose logs -f [service-name]
+```

+
+## Generating Self-Signed Certificates (Development/Testing)
+
+⚠️ **Warning**: Only use self-signed certificates for development and testing. Use proper CA-signed certificates in production.
+
+### Generate CA Certificate
+```bash
+# Create CA private key
+openssl genrsa -out ca.key 4096
+
+# Create CA certificate
+openssl req -new -x509 -days 365 -key ca.key -out ca.crt \
+  -subj "/C=AT/ST=Vienna/L=Vienna/O=Meldestelle/OU=IT/CN=Meldestelle-CA"
+```
+
+### Generate Server Certificates
+```bash
+# For each service, generate private key and certificate signing request
+openssl genrsa -out server.key 2048
+openssl req -new -key server.key -out server.csr \
+  -subj "/C=AT/ST=Vienna/L=Vienna/O=Meldestelle/OU=IT/CN=your-domain.com"
+
+# Sign the certificate with CA
+openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key \
+  -CAcreateserial -out server.crt
+
+# Clean up
+rm server.csr
+```
+
+### Generate Diffie-Hellman Parameters
+```bash
+openssl dhparam -out dhparam.pem 2048
+```
+
+## Production Certificate Setup
+
+### Option 1: Let's Encrypt (Recommended)
+Use Certbot to obtain free SSL certificates:
+
+```bash
+# Install certbot
+sudo apt-get install certbot
+
+# Obtain certificates
+sudo certbot certonly --standalone -d your-domain.com -d www.your-domain.com
+
+# Copy certificates to appropriate directories
+sudo cp /etc/letsencrypt/live/your-domain.com/fullchain.pem config/ssl/nginx/server.crt
+sudo cp /etc/letsencrypt/live/your-domain.com/privkey.pem config/ssl/nginx/server.key
+```
+
+### Option 2: Commercial CA
+1. Generate Certificate Signing Requests (CSRs)
+2. Submit CSRs to your Certificate Authority
+3. Download signed certificates
+4. Place certificates in appropriate directories
+
+### Option 3: Internal CA
+If using an internal Certificate Authority:
+1. Generate CSRs for each service
+2. Sign certificates with your internal CA
+3. Distribute CA certificate to all clients
+
+## File Permissions
+
+Ensure proper file permissions for security:
+
+```bash
+# Set restrictive permissions on private keys
+chmod 600 config/ssl/*/server.key
+chmod 600 config/ssl/*/redis.key
+chmod 600 config/ssl/*/prometheus.key
+
+# Set readable permissions on certificates
+chmod 644 config/ssl/*/server.crt
+chmod 644 config/ssl/*/ca.crt
+
+# Set directory permissions
+chmod 755 config/ssl/*/
+```
+
+## Docker Volume Mounts
+
+The certificates are mounted as read-only volumes in the Docker containers:
+
+```yaml
+volumes:
+  - ./config/ssl/nginx:/etc/ssl/nginx:ro
+  - ./config/ssl/keycloak:/opt/keycloak/conf:ro
+  # ... other mounts
+```
+
+## Certificate Renewal
+
+### Automated Renewal (Let's Encrypt)
+Set up a cron job for automatic renewal:
+
+```bash
+# Add to crontab
+0 12 * * * /usr/bin/certbot renew --quiet --post-hook "docker-compose -f docker-compose.prod.yml restart nginx"
+```
+
+### Manual Renewal
+1. Generate new certificates
+2. Replace old certificates in SSL directories
+3. Restart affected services:
+   ```bash
+   docker-compose -f docker-compose.prod.yml restart nginx keycloak grafana prometheus
+   ```
+
+## Security Best Practices
+
+1. **Use Strong Encryption**: Use at least 2048-bit RSA keys or 256-bit ECDSA keys
+2. **Regular Rotation**: Rotate certificates regularly (annually or bi-annually)
+3. **Secure Storage**: Store private keys securely and limit access
+4. **Monitor Expiration**: Set up monitoring for certificate expiration
+5. **Use HSTS**: Enable HTTP Strict Transport Security
+6. **Perfect Forward Secrecy**: Use ECDHE cipher suites
+7. **Certificate Transparency**: Monitor CT logs for unauthorized certificates
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Permission Denied**
+   ```bash
+   # Fix file permissions
+   sudo chown -R $USER:$USER config/ssl/
+   chmod -R 755 config/ssl/
+   chmod 600 config/ssl/*/server.key
+   ```
+
+2. **Certificate Verification Failed**
+   ```bash
+   # Verify certificate
+   openssl x509 -in config/ssl/nginx/server.crt -text -noout
+
+   # Check certificate chain
+   openssl verify -CAfile config/ssl/nginx/ca.crt config/ssl/nginx/server.crt
+   ```
+
+3. **TLS Handshake Errors**
+   - Check certificate validity dates
+   - Verify certificate matches hostname
+   - Ensure proper cipher suite configuration
+
+### Testing SSL Configuration
+
+```bash
+# Test SSL certificate
+openssl s_client -connect your-domain.com:443 -servername your-domain.com
+
+# Test with specific protocol
+openssl s_client -connect your-domain.com:443 -tls1_2
+
+# Check certificate expiration
+openssl x509 -in config/ssl/nginx/server.crt -noout -dates
+```
+
+## Support
+
+For certificate-related issues:
+1. Check service logs: `docker-compose -f docker-compose.prod.yml logs [service-name]`
+2. Verify certificate files exist and have correct permissions
+3. Test SSL configuration with OpenSSL tools
+4. Consult service-specific SSL documentation

+
+### Verschiedene Ports für mehrere Entwickler
+Wenn mehrere Entwickler gleichzeitig arbeiten, können Sie die Ports anpassen:
+
+```bash
+# Entwickler 1 (Standard)
+API_PORT=8081
+POSTGRES_EXTERNAL_PORT=5432
+REDIS_EXTERNAL_PORT=6379
+
+# Entwickler 2
+API_PORT=8082
+POSTGRES_EXTERNAL_PORT=5433
+REDIS_EXTERNAL_PORT=6380
+```
+
+## Sicherheitshinweise
+
+⚠️ **Wichtige Sicherheitshinweise:**
+
+1. **Niemals Produktionsgeheimnisse in die Versionskontrolle einbinden**
+2. **JWT_SECRET in der Produktion ändern**
+3. **Starke Passwörter für Produktionsumgebungen verwenden**
+4. **API-Schlüssel regelmäßig rotieren**
+5. **Datenbankzugangsdaten sicher aufbewahren**
+
+## Fehlerbehebung
+
+### Häufige Probleme
+
+1. **Verbindungsfehler zu PostgreSQL:**
+   - Überprüfen Sie `DB_HOST`, `DB_PORT`, `DB_USER`, `DB_PASSWORD`
+   - Stellen Sie sicher, dass der PostgreSQL-Container läuft
+
+2. **Redis-Verbindungsfehler:**
+   - Überprüfen Sie `REDIS_EVENT_STORE_HOST` und `REDIS_EVENT_STORE_PORT`
+   - Stellen Sie sicher, dass der Redis-Container läuft
+
+3. **JWT-Authentifizierungsfehler:**
+   - Überprüfen Sie `JWT_SECRET`, `JWT_ISSUER`, `JWT_AUDIENCE`
+   - Stellen Sie sicher, dass die Werte konsistent sind
+
+4. **Port-Konflikte:**
+   - Ändern Sie die Port-Variablen, wenn andere Services die gleichen Ports verwenden
+
