Personalizzazione della configmap Block Storage for VPC

È possibile personalizzare la Block Storage for VPC configmap per avere un maggiore controllo sulle impostazioni degli snapshot.

Scarica la mappa di configurazione Block Storage for VPC e esamina i parametri.

kubectl get cm addon-vpc-block-csi-driver-configmap -n kube-system -o yaml > vpc-configmap.yaml

Aprire il file configmap.yaml e aggiornare le impostazioni che si desidera modificare.
Riapplica la configmap al tuo cluster.
```
kubectl apply -f vpc-configmap.yaml
```
Verificare che i pod siano riavviati correttamente e che le configurazioni siano applicate
```
kubectl get pods -n kube-system | grep vpc-block
```
