Dynamic Volume Provisioning: Storage on Demand
Dynamic Volume Provisioning lets you request storage by its type (e.g., "fast-ssd") instead of pre-provisioning a disk. Kubernetes automatically creates a matching volume. This is standard for stateful apps.
Dynamic Volume Provisioning lets you request storage by its type (e.g., "fast-ssd") via a StorageClass, instead of manually creating a disk. When your app makes a PersistentVolumeClaim, Kubernetes automatically creates a matching PersistentVolume. This is the standard for stateful apps like databases. The footgun is the reclaimPolicy: `Delete` destroys the underlying storage when the claim is removed, while `Retain` can leave you paying for expensive, orphaned volumes.
