Changes:
- Replace bind mount (./data) with external named volume (nlcc-data)
- Volume must be created before first run: docker volume create nlcc-data
- Improves portability and follows Docker best practices
- Better separation between code and data
Benefits:
- Data persists across container rebuilds and updates
- Easier backup and restore operations
- Platform-agnostic (works same on Linux/Windows/macOS)
- Managed by Docker's volume system
- No permission issues with bind mounts
README Updates:
- Added volume creation step to installation instructions
- Documented volume management commands (create, inspect, backup, restore)
- Added backup/restore examples using alpine container
- Clarified data persistence behavior
Note: Existing deployments using ./data bind mount will need to:
1. Backup existing data: cp -r ./data ./data-backup
2. Create volume: docker volume create nlcc-data
3. Restart container: docker-compose up -d
4. Copy data to volume if needed
