## What it is
A Kubernetes dynamic volume provisioner that automatically creates Persistent Volumes on an existing NFS server, placing each volume in a subdirectory named after the namespace, PVC, and PV. It deploys via Helm or Kustomize and is maintained under kubernetes-sigs.

## Use cases
- dynamically provision persistent volumes from an existing nfs server in kubernetes
- auto-create subdirectories per pvc on nfs storage
- replace manual pv creation with pvc-based provisioning
- deploy nfs storage provisioner with helm
- give stateful workloads shared nfs-backed storage in a cluster

## When to choose
- you already run an NFS server and want dynamic PVC-based provisioning in Kubernetes
- you want per-claim subdirectories on a shared NFS export
- you prefer a simple Helm/Kustomize deployment over a full CSI driver

## When to avoid
- you need a full CSI driver with advanced features like snapshots, expansion, or access controls
- you have no existing NFS server to point at
- you need block storage or local-disk performance rather than shared network file storage
