+# Production Deployment Guide for dk0.dev
+
+This guide will help you deploy the portfolio application to production on dk0.dev.
+
+## Prerequisites
+
+1. **Server Requirements:**
+   - Ubuntu 20.04+ or similar Linux distribution
+   - Docker and Docker Compose installed
+   - Nginx or Traefik for reverse proxy
+   - SSL certificates (Let's Encrypt recommended)
+   - Domain `dk0.dev` pointing to your server
+
+2. **Required Environment Variables:**
+   - `MY_EMAIL`: Your contact email
+   - `MY_INFO_EMAIL`: Your info email
+   - `MY_PASSWORD`: Email password
+   - `MY_INFO_PASSWORD`: Info email password
+   - `ADMIN_BASIC_AUTH`: Admin credentials (format: `username:password`)
+
+## Quick Deployment
+
+### 1. Clone and Setup
+
+```bash
+# Clone the repository
+git clone <your-repo-url>
+cd portfolio
+
+# Make deployment script executable
+chmod +x scripts/production-deploy.sh
+```
+
+### 2. Configure Environment
+
+Create a `.env` file with your production settings:
+
+```bash
+# Copy the example
+cp env.example .env
+
+# Edit with your values
+nano .env
+```
+
+Required values:
+```env
+NODE_ENV=production
+NEXT_PUBLIC_BASE_URL=https://dk0.dev
+MY_EMAIL=contact@dk0.dev
+MY_INFO_EMAIL=info@dk0.dev
+MY_PASSWORD=your-actual-email-password
+MY_INFO_PASSWORD=your-actual-info-password
+ADMIN_BASIC_AUTH=admin:your-secure-password
+```
+
+### 3. Deploy
+
+```bash
+# Run the production deployment script
+./scripts/production-deploy.sh
+```
+
+### 4. Setup Reverse Proxy
+
+#### Option A: Nginx (Recommended)
+
+1. Install Nginx:
+```bash
+sudo apt update
+sudo apt install nginx
+```
+
+2. Copy the production nginx config:
+```bash
+sudo cp nginx.production.conf /etc/nginx/nginx.conf
+```
+
+3. Setup SSL certificates:
+```bash
+# Install Certbot
+sudo apt install certbot python3-certbot-nginx
+
+# Get SSL certificate
+sudo certbot --nginx -d dk0.dev -d www.dk0.dev
+```
+
+4. Restart Nginx:
+```bash
+sudo systemctl restart nginx
+sudo systemctl enable nginx
+```
+
+#### Option B: Traefik
+
+If using Traefik, ensure your Docker Compose file includes Traefik labels:
+
+```yaml
+labels:
+  - "traefik.enable=true"
+  - "traefik.http.routers.portfolio.rule=Host(`dk0.dev`)"
+  - "traefik.http.routers.portfolio.tls=true"
+  - "traefik.http.routers.portfolio.tls.certresolver=letsencrypt"
+```
+
+## Manual Deployment Steps
+
+If you prefer manual deployment:
+
+### 1. Create Proxy Network
+
+```bash
+docker network create proxy
+```
+
+### 2. Build and Start Services
+
+```bash
+# Build the application
+docker build -t portfolio-app:latest .
+
+# Start services
+docker-compose -f docker-compose.production.yml up -d
+```
+
+### 3. Run Database Migrations
+
+```bash
+# Wait for services to be healthy
+sleep 30
+
+# Run migrations
+docker exec portfolio-app npx prisma db push
+```
+
+### 4. Verify Deployment
+
+```bash
+# Check health
+curl http://localhost:3000/api/health
+
+# Check admin panel
+curl http://localhost:3000/manage
+```
+
+## Security Considerations
+
+### 1. Update Default Passwords
+
+**CRITICAL:** Change these default values:
+
+```env
+# Change the admin password
+ADMIN_BASIC_AUTH=admin:your-very-secure-password-here
+
+# Use strong email passwords
+MY_PASSWORD=your-strong-email-password
+MY_INFO_PASSWORD=your-strong-info-password
+```
+
+### 2. Firewall Configuration
+
+```bash
+# Allow only necessary ports
+sudo ufw allow 22    # SSH
+sudo ufw allow 80    # HTTP
+sudo ufw allow 443   # HTTPS
+sudo ufw enable
+```
+
+### 3. SSL/TLS Configuration
+
+Ensure you have valid SSL certificates. The nginx configuration expects:
+- `/etc/nginx/ssl/cert.pem` (SSL certificate)
+- `/etc/nginx/ssl/key.pem` (SSL private key)
+
+## Monitoring and Maintenance
+
+### 1. Health Checks
+
+```bash
+# Check application health
+curl https://dk0.dev/api/health
+
+# Check container status
+docker-compose ps
+
+# View logs
+docker-compose logs -f
+```
+
+### 2. Backup Database
+
+```bash
+# Create backup
+docker exec portfolio-postgres pg_dump -U portfolio_user portfolio_db > backup.sql
+
+# Restore backup
+docker exec -i portfolio-postgres psql -U portfolio_user portfolio_db < backup.sql
+```
+
+### 3. Update Application
+
+```bash
+# Pull latest changes
+git pull origin main
+
+# Rebuild and restart
+docker-compose down
+docker build -t portfolio-app:latest .
+docker-compose up -d
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Port 3000 not accessible:**
+   - Check if the container is running: `docker ps`
+   - Check logs: `docker-compose logs portfolio`
+
+2. **Database connection issues:**
+   - Ensure PostgreSQL is healthy: `docker-compose ps`
+   - Check database logs: `docker-compose logs postgres`
+
+3. **SSL certificate issues:**
+   - Verify certificate files exist and are readable
+   - Check nginx configuration: `nginx -t`
+
+4. **Rate limiting issues:**
+   - Check nginx rate limiting configuration
+   - Adjust limits in `nginx.production.conf`
+
+### Logs and Debugging
+
+```bash
+# Application logs
+docker-compose logs -f portfolio
+
+# Database logs
+docker-compose logs -f postgres
+
+# Nginx logs
+sudo tail -f /var/log/nginx/access.log
+sudo tail -f /var/log/nginx/error.log
+```
+
+## Performance Optimization
+
+### 1. Resource Limits
+
+The production Docker Compose file includes resource limits:
+- Portfolio app: 1GB RAM, 1 CPU
+- PostgreSQL: 512MB RAM, 0.5 CPU
+- Redis: 256MB RAM, 0.25 CPU
+
+### 2. Caching
+
+- Static assets are cached for 1 year
+- API responses are cached for 10 minutes
+- Admin routes are not cached for security
+
+### 3. Rate Limiting
+
+- API routes: 20 requests/second
+- Login routes: 10 requests/minute
+- Admin routes: 5 requests/minute
+
+## Support
+
+If you encounter issues:
+
+1. Check the logs first
+2. Verify all environment variables are set
+3. Ensure all services are healthy
+4. Check network connectivity
+5. Verify SSL certificates are valid
+
+For additional help, check the application logs and ensure all prerequisites are met.
