## 🚀 Überblick und Philosophie
|
||||
|
||||
Das Meldestelle-Projekt implementiert eine **moderne, sicherheitsorientierte Containerisierungsstrategie** basierend auf bewährten DevOps-Praktiken und Production-Ready-Standards. Unsere Docker-Architektur ist darauf ausgelegt:
|
||||
|
||||
- **Sicherheit first**: Alle Container laufen als Non-Root-User
|
||||
- **Optimale Performance**: Multi-stage Builds mit Layer-Caching
|
||||
- **Observability**: Umfassendes Monitoring und Health-Checks
|
||||
- **Skalierbarkeit**: Microservices-ready mit Service Discovery
|
||||
- **Wartbarkeit**: Standardisierte Templates und klare Konventionen

## 🐳 Dockerfile-Standards
|
||||
|
||||
### Template-Struktur

|
||||
|
||||
```
|
||||

## 🎼 Docker-Compose Organisation
|
||||
|
||||
### Multi-Environment Strategie
|
||||
|
||||
Unsere Compose-Dateien sind modular organisiert für verschiedene Einsatzszenarien:
|
||||
|
||||
```
|
||||
├── docker-compose.yml # ✅ Development (Infrastructure)
|
||||
├── docker-compose.prod.yml # ✅ Production (gehärtet, SSL/TLS)
|
||||
├── docker-compose.services.yml # 🆕 Application Services
|
||||
├── docker-compose.clients.yml # 🆕 Client Applications
|
||||
└── docker-compose.override.yml # 🆕 Local Development Overrides
|
||||
```
|
||||
|
||||
### Verwendungsszenarien
|
||||
|
||||
#### 🏠 Lokale Entwicklung - Vollständiges System
|
||||
|
||||
```bash
|
||||
# Alle Services einschließlich Clients
|
||||
docker-compose \
|
||||
-f docker-compose.yml \
|
||||
-f docker-compose.services.yml \
|
||||
-f docker-compose.clients.yml \
|
||||
up -d
|
||||
|
||||
# Nur Infrastructure für Backend-Entwicklung
|
||||
docker-compose -f docker-compose.yml up -d postgres redis kafka consul
|
||||
|
||||
# Mit Live-Reload für Frontend-Entwicklung
|
||||
docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d
|
||||
```
|
||||
|
||||
#### 🚀 Production Deployment
|
||||
|
||||
```bash
|
||||
# Production - Optimiert und sicher
|
||||
docker-compose \
|
||||
-f docker-compose.prod.yml \
|
||||
-f docker-compose.services.yml \
|
||||
up -d
|
||||
|
||||
# Mit spezifischen Environment-Variablen
|
||||
export POSTGRES_PASSWORD=$(openssl rand -base64 32)
|
||||
export REDIS_PASSWORD=$(openssl rand -base64 32)
|
||||
docker-compose -f docker-compose.prod.yml up -d
|
||||
```
|
||||
|
||||
#### 🧪 Testing Environment
|
||||
|
||||
```bash
|
||||
# Nur notwendige Services für Tests
|
||||
docker-compose -f docker-compose.yml up -d postgres redis
|
||||
./gradlew test
|
||||
|
||||
# End-to-End Tests
|
||||
docker-compose -f docker-compose.yml -f docker-compose.services.yml up -d
|
||||
./gradlew :client:web-app:jsTest
|
||||
```
|
||||
|
||||
### Service-Abhängigkeiten
|
||||
|
||||
```yaml
|
||||
# Typische Service-Abhängigkeiten in unserer Architektur
|
||||
depends_on:
|
||||
postgres:
|
||||
condition: service_healthy
|
||||
consul:
|
||||
condition: service_healthy
|
||||
redis:
|
||||
condition: service_healthy
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🛠️ Development-Workflow
|
||||
|
||||
### Schnellstart-Befehle
|
||||
|
||||
```bash
|
||||
# 🚀 Komplettes Development-Setup
|
||||
make dev-up # Startet alle Development-Services
|
||||
make dev-down # Stoppt alle Services
|
||||
make dev-logs # Zeigt Logs aller Services
|
||||
make dev-restart # Neustart aller Services
|
||||
|
||||
# 🔧 Service-spezifische Befehle
|
||||
make service-build SERVICE=ping-service # Service neu bauen
|
||||
make service-logs SERVICE=ping-service # Service-Logs anzeigen
|
||||
make service-restart SERVICE=ping-service # Service neustarten
|
||||
```
|
||||
|
||||
**Makefile-Beispiel:**
|
||||
|
||||
```makefile
|
||||
# Development commands
|
||||
.PHONY: dev-up dev-down dev-logs dev-restart
|
||||
|
||||
dev-up:
|
||||
docker-compose -f docker-compose.yml -f docker-compose.services.yml up -d
|
||||
@echo "🚀 Development environment started"
|
||||
@echo "📊 Grafana: http://localhost:3000 (admin/admin)"
|
||||
@echo "🔍 Prometheus: http://localhost:9090"
|
||||
@echo "🚪 API Gateway: http://localhost:8080"
|
||||
|
||||
dev-down:
|
||||
docker-compose -f docker-compose.yml -f docker-compose.services.yml down
|
||||
|
||||
dev-logs:
|
||||
docker-compose -f docker-compose.yml -f docker-compose.services.yml logs -f
|
||||
|
||||
dev-restart:
|
||||
$(MAKE) dev-down
|
||||
$(MAKE) dev-up
|
||||
|
||||
# Service-specific commands
|
||||
service-build:
|
||||
@test -n "$(SERVICE)" || (echo "❌ SERVICE parameter required"; exit 1)
|
||||
docker-compose -f docker-compose.yml -f docker-compose.services.yml build $(SERVICE)
|
||||
|
||||
service-logs:
|
||||
@test -n "$(SERVICE)" || (echo "❌ SERVICE parameter required"; exit 1)
|
||||
docker-compose logs -f $(SERVICE)
|
||||
|
||||
service-restart:
|
||||
@test -n "$(SERVICE)" || (echo "❌ SERVICE parameter required"; exit 1)
|
||||
docker-compose -f docker-compose.yml -f docker-compose.services.yml restart $(SERVICE)
|
||||
```
|
||||
|
||||
### Hot-Reload Development
|
||||
|
||||
**docker-compose.override.yml** für optimierte Entwicklung:
|
||||
|
||||
```yaml
|
||||
# Development overrides für Hot-Reload
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||
web-client:
|
||||
volumes:
|
||||
- ./client/web-app/src:/app/src:ro
|
||||
- ./client/common-ui/src:/app/common-ui/src:ro
|
||||
environment:
|
||||
- NODE_ENV=development
|
||||
command: npm run dev
|
||||
|
||||
ping-service:
|
||||
environment:
|
||||
- DEBUG=true
|
||||
- SPRING_DEVTOOLS_RESTART_ENABLED=true
|
||||
ports:
|
||||
- "5005:5005" # Debug-Port
|
||||
volumes:
|
||||
- ./temp/ping-service/src:/workspace/src:ro
|
||||
```
|
||||
|
||||
### Debugging von Services
|
||||
|
||||
```bash
|
||||
# Service im Debug-Modus starten
|
||||
docker-compose -f docker-compose.yml up -d ping-service
|
||||
docker-compose exec ping-service sh
|
||||
|
||||
# Logs in Echtzeit verfolgen
|
||||
docker-compose logs -f ping-service api-gateway
|
||||
|
||||
# Health-Check Status prüfen
|
||||
curl -s http://localhost:8082/actuator/health | jq
|
||||
curl -s http://localhost:8080/actuator/health | jq
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚀 Production-Deployment
|
||||
|
||||
### Security Hardening
|
||||
|
||||
Unsere Production-Konfiguration implementiert umfassende Sicherheitsmaßnahmen:
|
||||
|
||||
#### 🔒 SSL/TLS Everywhere
|
||||
|
||||
```bash
|
||||
# TLS-Zertifikate vorbereiten
|
||||
mkdir -p config/ssl/{postgres,redis,keycloak,grafana,prometheus,nginx}
|
||||
|
||||
# Let's Encrypt Zertifikate generieren
|
||||
certbot certonly --dns-route53 -d api.meldestelle.at
|
||||
certbot certonly --dns-route53 -d auth.meldestelle.at
|
||||
certbot certonly --dns-route53 -d monitor.meldestelle.at
|
||||
```
|
||||
|
||||
#### 🛡️ Environment Variables
|
||||
|
||||
**Erforderliche Production-Variablen:**
|
||||
|
||||
```bash
|
||||
# Datenschutz und Sicherheit
|
||||
export POSTGRES_USER=meldestelle_prod
|
||||
export POSTGRES_PASSWORD=$(openssl rand -base64 32)
|
||||
export POSTGRES_DB=meldestelle_prod
|
||||
export REDIS_PASSWORD=$(openssl rand -base64 32)
|
||||
|
||||
# Keycloak Admin
|
||||
export KEYCLOAK_ADMIN=admin
|
||||
export KEYCLOAK_ADMIN_PASSWORD=$(openssl rand -base64 32)
|
||||
export KC_DB_PASSWORD=${POSTGRES_PASSWORD}
|
||||
export KC_HOSTNAME=auth.meldestelle.at
|
||||
|
||||
# Monitoring
|
||||
export GF_SECURITY_ADMIN_USER=admin
|
||||
export GF_SECURITY_ADMIN_PASSWORD=$(openssl rand -base64 32)
|
||||
export GRAFANA_HOSTNAME=monitor.meldestelle.at
|
||||
export PROMETHEUS_HOSTNAME=metrics.meldestelle.at
|
||||
|
||||
# Kafka Security
|
||||
export KAFKA_BROKER_ID=1
|
||||
export KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
|
||||
```
|
||||
|
||||
#### 🌐 Reverse Proxy Configuration
|
||||
|
||||
**nginx.prod.conf** Beispiel:
|
||||
|
||||
```nginx
|
||||
upstream api_backend {
|
||||
server api-gateway:8080;
|
||||
keepalive 32;
|
||||
}
|
||||
|
||||
upstream auth_backend {
|
||||
server keycloak:8443;
|
||||
keepalive 32;
|
||||
}
|
||||
|
||||
upstream monitoring_backend {
|
||||
server grafana:3443;
|
||||
keepalive 32;
|
||||
}
|
||||
|
||||

### Resource Limits
|
||||
|
||||
Alle Production-Services haben definierte Resource-Limits:
|
||||
|
||||
```yaml
|
||||
# Beispiel für Resource-Management
|
||||
services:
|
||||
postgres:
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
memory: 1G
|
||||
cpus: '0.5'
|
||||
reservations:
|
||||
memory: 512M
|
||||
cpus: '0.25'
|
||||
|
||||
api-gateway:
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
memory: 512M
|
||||
cpus: '0.5'
|
||||
reservations:
|
||||
memory: 256M
|
||||
cpus: '0.25'
|
||||
```

|
||||
|
||||
## 📊 Monitoring und Observability
|
||||
|
||||
### Prometheus Metrics
|
||||
|
||||
Alle Services exposieren standardisierte Metrics:
|
||||
|
||||
```yaml
|
||||
# Service-Labels für Prometheus Autodiscovery
|
||||
labels:
|
||||
- "prometheus.scrape=true"
|
||||
- "prometheus.port=8080"
|
||||
- "prometheus.path=/actuator/prometheus"
|
||||
- "prometheus.service=${SERVICE_NAME}"
|
||||
```
|
||||
|
||||
### Grafana Dashboards
|
||||
|
||||
**Vorgefertigte Dashboards:**
|
||||
|
||||
- **Infrastructure Overview**: CPU, Memory, Disk, Network
|
||||

|
||||
|
||||
### Log Aggregation
|
||||
|
||||
```bash
|
||||
# Centralized logging mit ELK Stack (optional)
|
||||
docker-compose -f docker-compose.yml -f docker-compose.logging.yml up -d
|
||||
|
||||
# Log-Parsing für strukturierte Logs
|
||||
docker-compose logs --follow --tail=100 api-gateway | jq -r '.message'
|
||||
```

## 🔧 Troubleshooting
|
||||
|
||||
### Häufige Probleme und Lösungen
|
||||
|
||||
#### 🚫 Port-Konflikte
|
||||
|
||||
```bash
|
||||
# Überprüfe, welche Ports verwendet werden
|
||||
netstat -tulpn | grep :8080

lsof -i :8080
|
||||
|
||||
# Stoppe konfligierende Services
|
||||
docker-compose down
|
||||
sudo systemctl stop apache2 # Falls Apache läuft
|
||||
```
|
||||
|
||||
#### 🐌 Langsame Startup-Zeiten
|
||||
|
||||
```bash
|
||||
# Überprüfe Container-Ressourcen
|
||||
docker stats
|
||||
|
||||
# Health-Check Logs analysieren
|
||||
docker-compose logs ping-service | grep health
|
||||
|
||||
# Java Startup optimieren
|
||||
export JAVA_OPTS="$JAVA_OPTS -XX:TieredStopAtLevel=1 -noverify"
|
||||
```
|
||||
|
||||
#### 💾 Disk-Space Probleme
|
||||
|
||||
```bash
|
||||
# Docker-Cleanup
|
||||
docker system prune -a --volumes
|
||||
docker volume prune
|
||||
|
||||
# Log-Rotation für Container
|
||||
docker-compose logs --tail=1000 > /dev/null # Truncate logs
|
||||
```
|
||||
|
||||
#### 🌐 Service Discovery Issues
|
||||

curl -s http://localhost:8500/v1/health/state/any | jq
|
||||
|
||||
# Service Registration überprüfen
|
||||
curl -s http://localhost:8500/v1/catalog/services | jq
|
||||
|
||||
# DNS-Resolution testen
|
||||
docker-compose exec api-gateway nslookup ping-service
|
||||
```
|
||||
|
||||
### Debug-Kommandos

## ✅ Best Practices
|
||||
|
||||
### 🔐 Security Best Practices
|
||||
|
||||
1. **Non-Root Users**: Alle Container laufen mit dedizierten Non-Root-Usern
|
||||
2. **Minimal Base Images**: Alpine Linux für kleinste Angriffsfläche
|
||||
3. **Secrets Management**: Externe Secret-Stores für Production
|
||||
4. **Network Isolation**: Dedizierte Docker-Networks
|
||||
5. **Regular Updates**: Automatische Security-Updates für Base Images
|
||||
|
||||
### ⚡ Performance Best Practices
|
||||
|
||||
1. **Multi-Stage Builds**: Minimale Runtime-Images
|
||||
2. **Layer Caching**: Optimale COPY-Reihenfolge in Dockerfiles
|
||||
3. **Resource Limits**: Definierte Memory und CPU-Limits
|
||||
4. **Health Checks**: Proaktive Container-Health-Überwachung
|
||||
5. **JVM Tuning**: Container-aware JVM-Settings
|
||||
|
||||
### 🧹 Wartung Best Practices
|
||||
|
||||
1. **Version Pinning**: Explizite Image-Versionen in Production
|
||||
2. **Backup Strategies**: Automatische Volume-Backups
|
||||
3. **Log Rotation**: Begrenzte Log-Datei-Größen
|
||||
4. **Documentation**: Aktuelle README-Dateien pro Service
|
||||
5. **Testing**: Automatisierte Container-Tests
|
||||
|
||||
### 📦 Build Best Practices
|
||||
|
||||
```dockerfile
|
||||
# ✅ Gute Praktiken
|
||||
FROM eclipse-temurin:21-jre-alpine AS runtime
|
||||
RUN apk update && apk upgrade && rm -rf /var/cache/apk/*
|
||||
USER 1001:1001
|
||||
HEALTHCHECK --interval=30s CMD curl -f http://localhost:8080/health || exit 1
|
||||
```
|
||||
|
||||
```dockerfile
|
||||
# ❌ Zu vermeidende Praktiken
|
||||
FROM ubuntu:latest
|
||||
RUN apt-get update
|
||||
USER root
|
||||
```
|
||||
**Probleme:** Zu große Base-Image, keine Versionierung, fehlende Cleanup, Sicherheitsrisiko durch Root-User, keine Health Checks

## 7. Dokumentationsstandards
|
||||
|
||||
### 7.1. Sprache für Dokumentation
|
||||
|
||||
* **README-Dateien:** Alle README-Dokumentationen im Projekt müssen in **deutscher Sprache** verfasst werden.
|
||||
Dies gewährleistet Konsistenz und Zugänglichkeit für das deutsche Entwicklungsteam.
|
||||
|
||||
* **Code-Kommentare:** Komplexe Geschäftslogik und fachliche Zusammenhänge sollen in deutscher Sprache kommentiert werden.
|
||||
|
||||
* **API-Dokumentation:** OpenAPI-Beschreibungen und -Beispiele sind bevorzugt in deutscher Sprache zu verfassen,
|
||||
sofern keine internationalen Anforderungen bestehen.
|
||||
|
||||
### 7.2. Dokumentationsstruktur
|
||||
|
||||
* README-Dateien sollen eine einheitliche Struktur befolgen: Überblick, Architektur, Entwicklung, Tests, Deployment.
|
||||
|
||||
* Technische Begriffe dürfen in englischer Originalform verwendet werden, wenn keine etablierte deutsche Übersetzung existiert.

|
||||
- Alle `:infrastructure` Module (auth, cache, event-store, gateway, messaging, monitoring) mit README-INFRASTRUCTURE.md
|
||||
- `:temp:ping-service` mit README_TEMP.md
|
||||
- `:client` Module (common-ui, desktop-app, web-app) mit ClientModuleDocumentation.md
|
||||
|
||||
### ❌ **Noch offen:**
|
||||
1. **End-to-End "Tracer Bullet"-Test:** Nicht durchführbar, da docker-compose nicht installiert
