+# Deployment Guide
+
+## Prerequisites
+
+- Supabase project (managed or self-hosted)
+- Docker and Docker Compose installed
+- Domain name (optional, for production)
+- SSL certificate (for HTTPS, recommended)
+
+## Quick Start (Docker Compose)
+
+### 1. Clone the repository
+
+```bash
+git clone https://gitea.jeanlucmakiola.de/pantry-app/pantry.git
+cd pantry
+```
+
+### 2. Configure environment
+
+```bash
+cp .env.production.example .env.production
+# Edit .env.production with your Supabase credentials
+nano .env.production
+```
+
+Required environment variables:
+- `NUXT_PUBLIC_SUPABASE_URL` - Your Supabase project URL
+- `NUXT_PUBLIC_SUPABASE_ANON_KEY` - Your Supabase anonymous key
+
+### 3. Build and run
+
+```bash
+docker-compose -f docker-compose.prod.yml --env-file .env.production up -d
+```
+
+The app will be available at `http://localhost:3000`
+
+### 4. Verify deployment
+
+```bash
+# Check health
+curl http://localhost:3000/api/health
+
+# View logs
+docker-compose -f docker-compose.prod.yml logs -f app
+
+# Check status
+docker-compose -f docker-compose.prod.yml ps
+```
+
+## Supabase Setup
+
+### Option 1: Supabase Cloud (Recommended)
+
+1. Create a free account at [supabase.com](https://supabase.com)
+2. Create a new project
+3. Run migrations: `supabase/migrations/*.sql`
+4. Copy project URL and anon key to `.env.production`
+
+### Option 2: Self-Hosted Supabase
+
+Use the included `docker-compose.yml` for local Supabase:
+
+```bash
+# Create .env file
+cp .env.example .env
+# Edit .env with secure passwords
+nano .env
+
+# Start Supabase stack
+docker-compose up -d
+
+# Wait for services to be ready
+docker-compose ps
+
+# Run migrations
+docker-compose exec db psql -U postgres -f /docker-entrypoint-initdb.d/001_initial_schema.sql
+```
+
+Supabase will be available at:
+- API: http://localhost:54321
+- Studio: http://localhost:54323
+
+## Production Deployment Options
+
+### Option 1: Coolify (Recommended)
+
+1. Add new Resource → Docker Compose
+2. Paste `docker-compose.prod.yml`
+3. Add environment variables in Coolify UI
+4. Deploy
+
+### Option 2: Docker Standalone
+
+```bash
+# Build image
+docker build -t pantry:latest .
+
+# Run container
+docker run -d \
+  --name pantry \
+  -p 3000:3000 \
+  -e NUXT_PUBLIC_SUPABASE_URL=https://your-project.supabase.co \
+  -e NUXT_PUBLIC_SUPABASE_ANON_KEY=your-key \
+  --restart unless-stopped \
+  pantry:latest
+```
+
+### Option 3: Kubernetes
+
+Example deployment manifest:
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: pantry
+spec:
+  replicas: 2
+  selector:
+    matchLabels:
+      app: pantry
+  template:
+    metadata:
+      labels:
+        app: pantry
+    spec:
+      containers:
+      - name: pantry
+        image: pantry:latest
+        ports:
+        - containerPort: 3000
+        env:
+        - name: NUXT_PUBLIC_SUPABASE_URL
+          valueFrom:
+            secretKeyRef:
+              name: pantry-secrets
+              key: supabase-url
+        - name: NUXT_PUBLIC_SUPABASE_ANON_KEY
+          valueFrom:
+            secretKeyRef:
+              name: pantry-secrets
+              key: supabase-key
+        livenessProbe:
+          httpGet:
+            path: /api/health
+            port: 3000
+          initialDelaySeconds: 40
+          periodSeconds: 30
+        resources:
+          limits:
+            memory: "512Mi"
+            cpu: "1000m"
+          requests:
+            memory: "256Mi"
+            cpu: "500m"
+```
+
+### Option 4: VPS with Nginx
+
+```nginx
+# /etc/nginx/sites-available/pantry
+server {
+    listen 80;
+    server_name pantry.yourdomain.com;
+
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+## HTTPS/SSL
+
+### Using Let's Encrypt (Certbot)
+
+```bash
+# Install Certbot
+sudo apt install certbot python3-certbot-nginx
+
+# Get certificate
+sudo certbot --nginx -d pantry.yourdomain.com
+
+# Auto-renewal
+sudo certbot renew --dry-run
+```
+
+### Using Cloudflare
+
+1. Add your domain to Cloudflare
+2. Enable "Full (strict)" SSL/TLS mode
+3. Point DNS A record to your server IP
+4. Cloudflare handles SSL automatically
+
+## Monitoring
+
+### Health Checks
+
+```bash
+# Manual check
+curl http://localhost:3000/api/health
+
+# With watch
+watch -n 5 'curl -s http://localhost:3000/api/health | jq'
+```
+
+### Docker Stats
+
+```bash
+docker stats pantry-app
+```
+
+### Logs
+
+```bash
+# Follow logs
+docker-compose -f docker-compose.prod.yml logs -f
+
+# Last 100 lines
+docker logs --tail 100 pantry-app
+
+# Since timestamp
+docker logs --since "2024-01-01T00:00:00" pantry-app
+```
+
+## Updating
+
+### Pull latest changes
+
+```bash
+cd pantry
+git pull origin main
+
+# Rebuild and restart
+docker-compose -f docker-compose.prod.yml build
+docker-compose -f docker-compose.prod.yml up -d
+```
+
+### Rolling back
+
+```bash
+# Tag before upgrading
+docker tag pantry:latest pantry:backup-20240101
+
+# Rollback if needed
+docker-compose -f docker-compose.prod.yml down
+docker tag pantry:backup-20240101 pantry:latest
+docker-compose -f docker-compose.prod.yml up -d
+```
+
+## Backup
+
+### Database (Supabase)
+
+```bash
+# Manual backup
+pg_dump -h localhost -U postgres -d postgres > backup.sql
+
+# Restore
+psql -h localhost -U postgres -d postgres < backup.sql
+```
+
+### Docker Volumes
+
+```bash
+# Backup
+docker run --rm -v pantry_db-data:/data -v $(pwd):/backup ubuntu tar czf /backup/db-backup.tar.gz /data
+
+# Restore
+docker run --rm -v pantry_db-data:/data -v $(pwd):/backup ubuntu tar xzf /backup/db-backup.tar.gz -C /
+```
+
+## Troubleshooting
+
+### Container won't start
+
+```bash
+# Check logs
+docker logs pantry-app
+
+# Verify environment variables
+docker exec pantry-app env | grep NUXT
+
+# Inspect container
+docker inspect pantry-app
+```
+
+### Supabase connection issues
+
+1. Verify Supabase URL and key
+2. Check network connectivity
+3. Verify RLS policies in Supabase
+4. Check CORS settings
+
+### Performance issues
+
+1. Check resource limits
+2. Monitor with `docker stats`
+3. Increase memory/CPU limits in docker-compose
+4. Enable compression in Nginx
+
+### PWA not updating
+
+1. Clear browser cache
+2. Unregister service worker
+3. Check that service worker is being served with correct headers
+4. Verify manifest.json is accessible
+
+## Security Checklist
+
+- [ ] Use HTTPS (SSL certificate)
+- [ ] Set secure environment variables
+- [ ] Don't commit .env files
+- [ ] Use strong Supabase passwords
+- [ ] Enable RLS policies in Supabase
+- [ ] Keep Docker images updated
+- [ ] Use firewall rules
+- [ ] Regular backups
+- [ ] Monitor logs for suspicious activity
+
+## Performance Optimization
+
+- Enable CDN (Cloudflare)
+- Use HTTP/2
+- Enable gzip/brotli compression
+- Set proper cache headers
+- Optimize images
+- Use Supabase CDN for assets
