Struktur Grafana,Prometheus
Ada 2 jenis volume yang boleh buatkan kekeliruan :
| Syntax | Type | Where data is stored | Description |
|---|---|---|---|
- grafana_data:/var/lib/grafana |
Named volume | Inside Docker’s internal volume storage (e.g. /var/lib/docker/volumes/...) |
Docker manages it automatically. You don’t see it directly on your host. Persistent between container recreations. |
- ./data/grafana:/var/lib/grafana |
Bind mount | In your project folder (./data/grafana) |
Files are directly visible and editable on your host. You must create the folder first. |
| Aspect | Named Volume | Bind Mount |
|---|---|---|
| Visibility | Hidden inside Docker | Visible in your project folder |
| Created automatically | ✅ Yes | ❌ No (you must create it) |
| Backup manually | Harder | Easy (just copy folder) |
| Portability | Great for production | Great for local development |
| Performance | Slightly faster (Docker optimized) | Slightly slower on some OS (esp. macOS) |
- Use named volume (
grafana_data:) → for clean, persistent production setup - Use bind mount (
./data/grafana:) → for local visibility / debugging
