## What it is
A retired Kubernetes incubator project containing community-maintained out-of-tree dynamic PersistentVolume provisioners and a helper library for building custom provisioners. It is deprecated and its successor lives in kubernetes-sigs/sig-storage-lib-external-provisioner.

## Use cases
- dynamically provision persistent volumes in kubernetes
- build a custom external PV provisioner
- auto-create persistent volumes from storage classes
- deploy nfs provisioner for kubernetes
- run out-of-tree storage provisioners independent of kubernetes releases

## When to choose
- studying legacy kubernetes storage provisioner implementations
- maintaining an old cluster that still depends on these provisioners

## When to avoid
- starting a new kubernetes storage project - use kubernetes-sigs/sig-storage-lib-external-provisioner or CSI drivers instead
- needing maintained or supported storage provisioning

## Facets
- artifact type: library
- maturity: abandoned
- function: infrastructure-as-code, developer-tools
- domain: cloud-computing, infrastructure-as-code
- platform: go, cloud
- tags: kubernetes, persistent-volumes, dynamic-provisioning, storage-classes, deprecated, nfs-provisioner, out-of-tree, storage-provisioning, containers, devops, docker
