In Docker runtime, `pvc.claimName` maps to a Docker named volume -- providing a more convenient and secure alternative to host-path bind mounts for sharing data across sandboxes. + +> **What is `pvc`?** The `pvc` backend is a runtime-neutral abstraction. In Kubernetes it maps to a PersistentVolumeClaim; in Docker it maps to a named volume. The same API request works on both runtimes.
