## Persistent Volume Provisioning
This example shows how to use dynamic persistent volume provisioning.
### Prerequisites
This example assumes that you have an understanding of Kubernetes administration and can modify the
scripts that launch kube-controller-manager.
### Admin Configuration
The admin must define `StorageClass` objects that describe named "classes" of storage offered in a cluster. Different classes might map to arbitrary levels or policies determined by the admin. When configuring a `StorageClass` object for persistent volume provisioning, the admin will need to describe the type of provis...
The name of a StorageClass object is significant, and is how users can request a particular class, by specifying the name in their `PersistentVolumeClaim`. The `provisioner` field must be specified as it determines what volume plugin is used for provisioning PVs. The `parameters` field contains the parameters that desc...
See [Kubernetes StorageClass documentation](https://kubernetes.io/docs/user-guide/persistent-volumes/#storageclasses) for complete reference of all supported parameters.
#### AWS
```yaml
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: slow
provisioner: kubernetes.io/aws-ebs
parameters:
type: io1
zones: us-east-1d, us-east-1c
iopsPerGB: "10"
fsType: ext4
```
* `type`: `io1`, `gp2`, `sc1`, `st1`. See AWS docs for details. Default: `gp2`.
* `zone`: AWS zone. If neither zone nor zones is specified, volumes are generally round-robin-ed across all active zones where Kubernetes cluster has a node. Note: zone and zones parameters must not be used at the same time.
* `zones`: a comma separated list of AWS zone(s). If neither zone nor zones is specified, volumes are generally round-robin-ed across all active zones where Kubernetes cluster has a node. Note: zone and zones parameters must not be used at the same time.
* `iopsPerGB`: only for `io1` volumes. I/O operations per second per GiB. AWS volume plugin multiplies this with size of requested volume to compute IOPS of the volume and caps it at 20 000 IOPS (maximum supported by AWS, see AWS docs).
* `encrypted`: denotes whether the EBS volume should be encrypted or not. Valid values are `true` or `false`.
* `kmsKeyId`: optional. The full Amazon Resource Name of the key to use when encrypting the volume. If none is supplied but `encrypted` is true, a key is generated by AWS. See AWS docs for valid ARN value.
* `fsType`: fsType that are supported by kubernetes. Default: `"ext4"`.
#### GCE
```yaml
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: slow
provisioner: kubernetes.io/gce-pd
parameters:
type: pd-standard
zone: us-central1-a
fsType: ext4
```
* `type`: `pd-standard` or `pd-ssd`. Default: `pd-ssd`
* `zone`: GCE zone. If neither zone nor zones is specified, volumes are generally round-robin-ed across all active zones where Kubernetes cluster has a node. Note: zone and zones parameters must not be used at the same time.
* `zones`: a comma separated list of GCE zone(s). If neither zone nor zones is specified, volumes are generally round-robin-ed across all active zones where Kubernetes cluster has a node. Note: zone and zones parameters must not be used at the same time.
#### vSphere
```yaml
