## ERPNext Deployment
|
||
|
||
| Komponente | Typ | Details |
|
||
|--------------------|------------|--------------------------------------------|
|
||
| Nginx | Deployment | Frontend, `frappeSiteNameHeader=expertfab.de` |
|
||
| Gunicorn | Deployment | Web Workers |
|
||
| Worker default | Deployment | Background Jobs |
|
||

||
| Worker long | Deployment | Lange Jobs |
|
||
| MariaDB | StatefulSet| v10.6, PVC: 3Gi RWO |
|
||
| DragonflyDB cache | Deployment | Redis-kompatibel |
|
||
| DragonflyDB queue | Deployment | Redis-kompatibel, PVC: 2Gi RWO (Anmerkung¹)|
|
||
|
||
> ¹ Helm-Values definieren 2Gi für Queue, tatsächliche PVC zeigt 3Gi Sites-Volume als RWX
|
||
|
||
**Helm Chart:** frappe/erpnext 8.0.14
|
||
**Custom Image:** git.expertfab.de/expertfab/customdocker:1.0.2

## DNS-Besonderheit (Hairpin-NAT)
|
||
|
||
OPNsense löst nur `www.expertfab.de` → `10.42.71.60` (intern) auf.
|
||
`expertfab.de` (ohne www) → öffentliche IP → von innen nicht erreichbar.
|
||
|
||
**Fix:** Frappe `host_name` = `https://www.expertfab.de`
|
||
**Pfad:** `/home/frappe/frappe-bench/sites/expertfab.de/site_config.json`
|
||
**Betrifft:** wkhtmltopdf PDF-Generierung (hängt sonst 120s → 504)
