```

---

## Backup & Disaster Recovery

### Automated Backup Script

```bash
#!/bin/bash
# backup.sh - Daily backup script

BACKUP_DIR="/backups/memento"
DATE=$(date +%Y%m%d_%H%M%S)

# Create backup directory
mkdir -p "$BACKUP_DIR/$DATE"

# Backup database
docker compose exec keep-notes \
  sqlite3 /app/prisma/dev.db ".backup /app/prisma/backup.db"

# Copy to host
docker cp memento-web:/app/prisma/backup.db \
  "$BACKUP_DIR/$DATE/database.db"

# Backup uploads
docker cp memento-web:/app/public/uploads \
  "$BACKUP_DIR/$DATE/"

# Compress
tar -czf "$BACKUP_DIR/memento-$DATE.tar.gz" -C "$BACKUP_DIR" $DATE
rm -rf "$BACKUP_DIR/$DATE"

# Keep last 7 days
find "$BACKUP_DIR" -name "*.tar.gz" -mtime +7 -delete

echo "Backup completed: memento-$DATE.tar.gz"
```

### Schedule with Cron

```bash
# Edit crontab
crontab -e

# Add daily backup at 2 AM
0 2 * * * /path/to/backup.sh
```

### Restore from Backup

```bash
# Extract backup
tar -xzf memento-20240109_020000.tar.gz

# Restore database
docker cp memento-20240109_020000/database.db \
  memento-web:/app/prisma/restore.db

docker compose exec keep-notes \
  sqlite3 /app/prisma/dev.db ".restore /app/prisma/restore.db"

# Restore uploads
docker cp memento-20240109_020000/uploads/. \
  memento-web:/app/public/uploads/

# Restart services
docker compose restart
```

## Security Hardening

### 1. Docker Security

```yaml
# docker-compose.yml hardening
services:
  keep-notes:
    # ... existing config
    security_opt:
      - no-new-privileges:true
    read_only: true
    tmpfs:
      - /tmp
    cap_drop:
      - ALL
    cap_add:
      - NET_BIND_SERVICE
```

### 2. Network Security

```yaml
# Isolate services
networks:
  memento-network:
    driver: bridge
    internal: false  # Set to true to block external access
    ipam:
      config:
        - subnet: 172.20.0.0/16
```

### 3. Secrets Management

```bash
# Use Docker Secrets (Swarm mode)
echo "your-secret" | docker secret create nextauth_secret -

# In docker-compose.yml
services:
  keep-notes:
    secrets:
      - nextauth_secret
    environment:
      NEXTAUTH_SECRET_FILE: /run/secrets/nextauth_secret

secrets:
  nextauth_secret:
    external: true
```

### 4. Update Base Images

```bash
# Update to latest Alpine
docker pull node:20-alpine

# Rebuild
docker compose build --no-cache
```

---

## Troubleshooting

### Container Won't Start

```bash
# Check logs
docker compose logs keep-notes

# Inspect container
docker inspect memento-web

# Check resource usage
docker stats

# Restart Docker daemon
sudo systemctl restart docker
```

### Database Connection Issues

```bash
# Verify database file exists
docker compose exec keep-notes ls -la /app/prisma/dev.db

# Check permissions
docker compose exec keep-notes ls -la /app/prisma/

# Re-run migrations
docker compose exec keep-notes npx prisma migrate deploy
```

### Port Conflicts

```bash
# Check what's using port 3000
sudo lsof -i :3000

# Change port in docker-compose.yml
ports:
  - "3001:3000"  # Use 3001 instead
```

### Out of Memory

```bash
# Increase Docker memory limit
# Docker Desktop -> Settings -> Resources -> Memory: 4GB+

# Or add memory limit in docker-compose.yml
services:
  keep-notes:
    deploy:
      resources:
        limits:
          memory: 2G
```

### Permission Issues

```bash
# Fix file permissions
docker compose exec keep-notes chown -R nextjs:nodejs /app/prisma
docker compose exec keep-notes chmod 644 /app/prisma/dev.db
```

---

## Performance Optimization

### 1. Enable BuildKit

```bash
# Set environment variable
export DOCKER_BUILDKIT=1
export COMPOSE_DOCKER_CLI_BUILD=1
```

### 2. Multi-Stage Build

Already implemented in Dockerfiles to reduce image size.

### 3. Layer Caching

```dockerfile
# Cache node_modules
COPY package*.json ./
RUN npm ci
COPY . .
```

### 4. Resource Limits

```yaml
# docker-compose.yml
services:
  keep-notes:
    deploy:
      resources:
        limits:
          cpus: '1'
          memory: 2G
        reservations:
          cpus: '0.5'
          memory: 1G
```

### 5. Database Optimization

```bash
# Run VACUUM to optimize SQLite
docker compose exec keep-notes sqlite3 /app/prisma/dev.db "VACUUM;"

# Analyze query performance
docker compose exec keep-notes npx prisma studio
```

---

## CI/CD Integration

### GitHub Actions Example

```yaml
# .github/workflows/deploy.yml
name: Deploy to Production

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - name: Login to Docker Hub
        uses: docker/login-action@v2
        with:
          username: ${{ secrets.DOCKER_USERNAME }}
          password: ${{ secrets.DOCKER_PASSWORD }}

      - name: Build and push
        run: |
          docker build -t yourusername/memento-web:latest ./keep-notes
          docker push yourusername/memento-web:latest

      - name: Deploy to server
        uses: appleboy/ssh-action@master
        with:
          host: ${{ secrets.HOST }}
          username: ${{ secrets.USERNAME }}
          key: ${{ secrets.SSH_KEY }}
          script: |
            cd /app/memento
            docker compose pull
            docker compose up -d
```

---

## Development vs Production

### Development (Local)

```bash
# Use local Next.js dev server
npm run dev

# Hot reload enabled
# Source maps enabled
# Detailed error messages
```

### Production (Docker)

```bash
# Use optimized production build
docker compose up -d

# Minified code
# Optimized images
# Server-side rendering
# Health checks enabled
```

---

## Migration from Local to Docker

### 1. Export Existing Data

```bash
# From local development
sqlite3 keep-notes/prisma/dev.db ".dump" > backup.sql

# Or copy database file
cp keep-notes/prisma/dev.db ./dev-backup.db
```

### 2. Import to Docker

```bash
# Copy to container
docker cp ./dev-backup.db memento-web:/app/prisma/dev.db

# Verify
docker compose exec keep-notes sqlite3 /app/prisma/dev.db "SELECT COUNT(*) FROM Note;"
```

### 3. Update Environment

```bash
# Copy .env to .env.production
cp .env .env.production

# Update URLs for production
NEXTAUTH_URL="https://your-domain.com"
```

## Update Strategy

### Rolling Updates

```bash
# Zero-downtime deployment
docker compose up -d --no-deps --build keep-notes

# Or use multiple instances
docker compose up -d --scale keep-notes=2
```

### Rollback

```bash
# Revert to previous version
docker compose down
git checkout <previous-commit>
docker compose up -d --build
```
