+# 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
+
+## Support

+# Coolify Deployment Guide
+
+## Prerequisites
+
+- Coolify instance running (self-hosted or cloud)
+- Gitea repository accessible to Coolify
+- Supabase project (cloud or self-hosted)
+- Domain name (optional, for production)
+
+## Deployment Steps
+
+### 1. Prepare Supabase
+
+#### Option A: Supabase Cloud
+
+1. Sign in to [supabase.com](https://supabase.com)
+2. Create new project (or use existing)
+3. Run migrations:
+   - Go to SQL Editor
+   - Copy/paste each file from `supabase/migrations/`
+   - Run in order: 001_, 002_, 003_, etc.
+4. Get credentials:
+   - Project Settings → API
+   - Copy Project URL
+   - Copy `anon` / `public` key
+
+#### Option B: Self-Hosted Supabase
+
+```bash
+cd supabase
+docker-compose up -d
+# Wait for services to start
+docker-compose ps
+```
+
+Migrations run automatically from `supabase/migrations/` directory.
+
+### 2. Add Resource in Coolify
+
+1. Log in to Coolify
+2. Click "New Resource"
+3. Select "Docker Compose"
+4. Choose deployment source:
+   - **Git Repository** (recommended)
+   - Public Git Repository
+   - Docker Image
+
+### 3. Configure Git Repository
+
+If using Git source:
+
+1. **Repository URL:** 
+   ```
+   https://gitea.jeanlucmakiola.de/pantry-app/pantry.git
+   ```
+
+2. **Branch:** `main` (or `develop` for staging)
+
+3. **Docker Compose File:** `docker-compose.prod.yml`
+
+4. **Build Path:** Leave empty (uses root)
+
+### 4. Set Environment Variables
+
+In Coolify → Environment Variables, add:
+
+```bash
+# Required
+NUXT_PUBLIC_SUPABASE_URL=https://your-project.supabase.co
+NUXT_PUBLIC_SUPABASE_ANON_KEY=your-anon-key-here
+
+# Optional
+NODE_ENV=production
+HOST=0.0.0.0
+PORT=3000
+```
+
+**Security Note:** Never commit `.env` files with real credentials!
+
+### 5. Configure Domain (Optional)
+
+1. In Coolify → Domains
+2. Add your domain: `pantry.yourdomain.com`
+3. Coolify auto-provisions SSL with Let's Encrypt
+4. DNS: Point A record to Coolify server IP
+
+### 6. Deploy
+
+1. Click "Deploy" button
+2. Watch build logs
+3. Wait for "Deployed successfully" message
+
+Expected deploy time: 2-5 minutes
+
+### 7. Verify Deployment
+
+#### Health Check
+
+```bash
+curl https://pantry.yourdomain.com/api/health
+```
+
+Expected response:
+```json
+{
+  "status": "ok",
+  "timestamp": "2026-02-25T00:00:00.000Z",
+  "uptime": 123.456
+}
+```
+
+#### PWA Check
+
+1. Visit app in browser
+2. Open DevTools → Application → Manifest
+3. Verify manifest loads
+4. Check Service Worker is registered
+
+#### Functionality Test
+
+- [ ] Homepage loads
+- [ ] Can sign up / sign in
+- [ ] Can view inventory
+- [ ] Can add item
+- [ ] PWA install prompt appears
+- [ ] Offline mode works
+
+## Troubleshooting
+
+### Build Fails
+
+**Check build logs in Coolify:**
+
+Common issues:
+- Missing dependencies → Check package.json
+- npm/node version mismatch → Use Node 20 Alpine
+- Out of memory → Increase Coolify resource limits
+
+### Container Won't Start
+
+**Check runtime logs in Coolify:**
+
+Common issues:
+- Missing environment variables
+- Port conflict (use 3000)
+- Supabase connection timeout
+
+### Supabase Connection Error
+
+1. Verify Supabase URL is correct (no trailing slash)
+2. Check anon key is valid
+3. Test Supabase API directly:
+   ```bash
+   curl https://your-project.supabase.co/rest/v1/
+   ```
+4. Check Supabase RLS policies allow access
+
+### SSL Certificate Issues
+
+Coolify should auto-provision Let's Encrypt cert:
+- Ensure domain points to correct IP
+- Check DNS propagation (can take 48h)
+- Verify port 80/443 open on firewall
+
+### App Loads but No Data
+
+1. Check browser console for errors
+2. Verify Supabase connection in Network tab
+3. Check RLS policies in Supabase
+4. Verify migrations ran successfully
+
+## Continuous Deployment
+
+### Auto-Deploy on Push
+
+1. In Coolify → Settings → Webhooks
+2. Copy webhook URL
+3. In Gitea → Repo → Settings → Webhooks
+4. Add webhook:
+   - URL: [Coolify webhook URL]
+   - Events: Push events
+   - Branch: main (or develop)
+
+Now every git push triggers auto-deployment!
+
+### Manual Deploy
+
+In Coolify interface:
+1. Click "Deploy Latest" button
+2. Or use Coolify API:
+   ```bash
+   curl -X POST https://coolify.example.com/api/deploy/[resource-id] \
+     -H "Authorization: Bearer [your-token]"
+   ```
+
+## Monitoring
+
+### View Logs
+
+Coolify Dashboard → Logs tab
+
+Real-time logs:
+```bash
+# If SSH access to Coolify host
+docker logs -f [container-name]
+```
+
+### Resource Usage
+
+Coolify shows:
+- CPU usage
+- Memory usage
+- Network traffic
+- Storage
+
+### Uptime Monitoring
+
+Recommended external services:
+- UptimeRobot (free tier)
+- BetterStack
+- Freshping
+
+Monitor: `https://pantry.yourdomain.com/api/health`
+
+## Rollback
+
+### To Previous Version
+
+1. In Coolify → Deployments
+2. Click on previous successful deployment
+3. Click "Redeploy"
+
+### Using Git Tags
+
+```bash
+# Tag current release
+git tag -a v0.1.0 -m "MVP Release"
+git push origin v0.1.0
+
+# Rollback by changing branch in Coolify
+# Or deploy specific tag
+```
+
+## Performance Optimization
+
+### Resource Limits
+
+In docker-compose.prod.yml:
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 512M
+      cpus: '1.0'
+```
+
+Adjust based on traffic.
+
+### CDN (Recommended)
+
+1. Add domain to Cloudflare
+2. Set DNS proxy (orange cloud)
+3. Enable caching rules
+4. Set SSL to "Full (strict)"
+
+**Result:** ~50% faster load times globally
+
+### Database Connection Pooling
+
+If self-hosting Supabase:
+- Use PgBouncer (included in Supabase)
+- Set max connections: 20-50
+
+## Security Checklist
+
+Before going live:
+
+- [ ] HTTPS enabled (automatic with Coolify)
+- [ ] Environment variables set (not in repo)
+- [ ] Supabase RLS policies enabled
+- [ ] Strong database passwords
+- [ ] Firewall configured (only 80/443 open)
+- [ ] Supabase auth configured
+- [ ] Regular backups enabled
+- [ ] Monitoring alerts set up
+
+## Backup Strategy
+
+### Database Backups
+
+**Supabase Cloud:** Automatic daily backups
+
+**Self-hosted:**
+```bash
+# Manual backup
+docker exec supabase-db pg_dump -U postgres > backup.sql
+
+# Automated (cron)
+0 2 * * * /path/to/backup-script.sh
+```
+
+### Volume Backups
+
+Coolify persistent volumes:
+```bash
+docker run --rm \
+  -v coolify_pantry_data:/data \
+  -v $(pwd):/backup \
+  ubuntu tar czf /backup/pantry-backup.tar.gz /data
+```
+
+## Staging Environment
+
+Recommended setup:
+
+**Production:**
+- Branch: `main`
+- Domain: `pantry.yourdomain.com`
+- Supabase: Production project
+
+**Staging:**
+- Branch: `develop`
+- Domain: `staging.pantry.yourdomain.com`
+- Supabase: Separate test project
+
+In Coolify, create two resources pointing to different branches.
+
+## Cost Estimate
+
+**Coolify (self-hosted):**
+- VPS: $5-10/month (Hetzner, Digital Ocean)
+- Domain: $10-15/year
+- **Total:** ~$8/month
+
+**Supabase Cloud:**
+- Free tier: 500MB database, 1GB file storage
+- Pro tier: $25/month (more resources)
+
+**Total Cost:** $8-33/month for full stack
