-## 🔄 GitOps & Deployment
+## 🚀 Migratie van Host Services naar Kubernetes

-Wijzigingen in de `k8s/` manifests worden automatisch gesynchroniseerd via Gitea Actions naar de centrale GitOps repository [`k8s-infra-vmserver`](https://git.bnhmeijer.nl/bart/k8s-infra-vmserver.git) onder `workloads/htpc/`, waarna ArgoCD deze reconcileert.
+### Radarr
+Voor het migreren van de standalone `radarr.service` op `10.2.0.4` naar de Kubernetes pod is een geautomatiseerd script beschikbaar:
+
+```bash
+# Migratie uitvoeren (stopt host service, synct /storage/var/lib/radarr naar K8s PVC, start pod):
+./migrate_radarr_to_cluster.sh
+
+# Terugrollen naar standalone service indien gewenst:
+./rollback_radarr_migration.sh
+```
+
+- **Dataopslag**: PersistentVolumeClaim `radarr-config` (10Gi, `local-path` op `/datadisk/infra/pv`).
+- **Mediaopslag**: HostPath `/datadisk` gemount op `/datadisk` (voor films in `/datadisk/htpc/Films` en downloads in `/datadisk/upload`).
+- **Netwerk & Ingress**: Luistert op poort `7878` (zowel via ClusterIP als HostPort `7878` op `10.2.0.4`), waardoor de bestaande Apache reverse proxy rule (`ProxyPass /radarr http://127.0.0.1:7878/radarr`) naadloos blijft functioneren.
