## 🚀 Five-Minute Deployment

### Step 1: Prepare (2 minutes)
```bash
cd /opt/digiserver-v2

# Generate secret key
SECRET=$(python -c "import secrets; print(secrets.token_urlsafe(32))")

# Create .env file
cat > .env << EOF
SECRET_KEY=$SECRET
ADMIN_USERNAME=admin
ADMIN_PASSWORD=YourStrongPassword123!
ADMIN_EMAIL=admin@company.com
DOMAIN=your-domain.com
EMAIL=admin@company.com
FLASK_ENV=production
EOF

chmod 600 .env
```

### Step 2: Deploy (2 minutes)
```bash
# Build and start
docker-compose build
docker-compose up -d

# Wait for startup
sleep 30

# Initialize database
docker-compose exec digiserver-app flask db upgrade
```

### Step 3: Verify (1 minute)
```bash
# Health check
curl -k https://your-domain/api/health

# CORS check
curl -i -k https://your-domain/api/playlists

# View logs
docker-compose logs --tail=20 digiserver-app
```

## 📋 Complete Deployment Checklist

### Pre-Deployment (24 hours before)
- [ ] Review [DEPLOYMENT_READINESS_SUMMARY.md](DEPLOYMENT_READINESS_SUMMARY.md)

- [ ] Plan SSL strategy (self-signed, Let's Encrypt, or commercial)
- [ ] Backup current database (if migrating)
- [ ] Schedule maintenance window
- [ ] Notify stakeholders

### Deployment Day
- [ ] Create .env file with production values

- [ ] Run: `docker-compose up -d`
- [ ] Wait 30 seconds for startup
- [ ] Run database migrations if needed
- [ ] Verify health checks passing
- [ ] Test API endpoints
- [ ] Verify CORS headers present

### Post-Deployment (First 24 hours)
- [ ] Monitor logs for errors
- [ ] Test player connections
- [ ] Verify playlist fetching works
- [ ] Check container health status
- [ ] Monitor resource usage
- [ ] Backup database
- [ ] Document any issues
- [ ] Create deployment log entry

### Ongoing Maintenance
- [ ] Daily database backups
- [ ] Weekly security updates check
- [ ] Monthly certificate expiry review
- [ ] Quarterly performance review

## 🛡️ Security Considerations

### Enabled Security Features ✅
- **HTTPS**: Enforced with automatic HTTP→HTTPS redirect
- **CORS**: Configured for `/api/*` endpoints
- **Secure Cookies**: `SESSION_COOKIE_SECURE=True`, `SESSION_COOKIE_HTTPONLY=True`
- **Session Protection**: `SESSION_COOKIE_SAMESITE=Lax`
- **Security Headers**: X-Frame-Options, X-Content-Type-Options, CSP
- **Non-root Container**: Runs as `appuser:1000`
- **TLS 1.2/1.3**: Latest protocols enabled
- **HSTS**: Configured at 365 days

### Recommended Additional Steps
1. **SSL Certificate**: Upgrade from self-signed to Let's Encrypt
   ```bash
   certbot certonly --standalone -d your-domain.com
   cp /etc/letsencrypt/live/your-domain.com/* data/nginx-ssl/
   ```

2. **Database**: Backup daily
   ```bash
   0 2 * * * docker-compose exec digiserver-app \
     cp instance/dashboard.db /backup/dashboard.db.$(date +%Y%m%d)
   ```

3. **Monitoring**: Set up log aggregation
4. **Firewall**: Only allow ports 80 and 443
5. **Updates**: Check for security updates monthly

## 🔍 Verification Commands

### Health Check
```bash
curl -k https://your-domain/api/health

# Expected response:
# {"status":"healthy","timestamp":"...","version":"2.0.0"}
```

### CORS Header Verification
```bash
curl -i -k https://your-domain/api/playlists | grep -i access-control

# Expected headers:
# access-control-allow-origin: *
# access-control-allow-methods: GET, POST, PUT, DELETE, OPTIONS
# access-control-allow-headers: Content-Type, Authorization
# access-control-max-age: 3600
```

### Certificate Verification
```bash
# Check certificate validity
openssl x509 -in data/nginx-ssl/cert.pem -text -noout

# Check expiry date
openssl x509 -enddate -noout -in data/nginx-ssl/cert.pem
```

### Container Health
```bash
docker-compose ps

# Expected output:
# NAME                STATUS            PORTS
# digiserver-app      Up (healthy)      5000/tcp
# digiserver-nginx    Up (healthy)      80→80, 443→443
```

## 📊 Performance Tuning

### For Small Deployments (1-20 players)
```yaml
# docker-compose.yml
services:
  digiserver-app:
    environment:
      - GUNICORN_WORKERS=2
      - GUNICORN_THREADS=4
```

### For Medium Deployments (20-100 players)
```yaml
environment:
  - GUNICORN_WORKERS=4
  - GUNICORN_THREADS=4
```

### For Large Deployments (100+ players)
- Upgrade to PostgreSQL database
- Use load balancer with multiple app instances
- Add Redis caching layer
- Implement CDN for media files

---

## 🆘 Troubleshooting

### "Connection Refused" on HTTPS
```bash
# Check containers running
docker-compose ps

# Check nginx logs
docker-compose logs nginx

# Verify SSL certificate exists
ls -la data/nginx-ssl/
```

### "Permission Denied" Errors
```bash
# Fix permissions
docker-compose exec digiserver-app chmod 755 /app
docker-compose restart
```

### "Database Locked" Error
```bash
# Restart application
docker-compose restart digiserver-app

# If persistent, restore from backup
docker-compose down
cp /backup/dashboard.db.bak data/instance/dashboard.db
docker-compose up -d
```

### High Memory Usage
```bash
# Check memory usage
docker stats

# Reduce workers if needed
docker-compose down
# Edit docker-compose.yml, set GUNICORN_WORKERS=2
docker-compose up -d
```
