You are not restricted to specifying the "internal" provisioners
listed here (whose names are prefixed with "kubernetes.io" and shipped
alongside Kubernetes). You can also run and specify external provisioners,
which are independent programs that follow a [specification](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/volume-provisioning.md)
defined by Kubernetes. Authors of external provisioners have full discretion
over where their code lives, how the provisioner is shipped, how it needs to be
run, what volume plugin it uses (including Flex), etc. The repository [kubernetes-incubator/external-storage](https://github.com/kubernetes-incubator/external-storage)
houses a library for writing external provisioners that implements the bulk of
the specification plus various community-maintained external provisioners.
