In this exercise, you create a hostPath PersistentVolume. Kubernetes supports hostPath for development and testing on a single-node cluster. A hostPath PersistentVolume uses a file or directory on the Node to emulate network-attached storage.
In a production cluster, you would not use hostPath. Instead a cluster administrator would provision a network resource like a Google Compute Engine persistent disk, an NFS share, or an Amazon Elastic Block Store volume. Cluster administrators can also use StorageClasses to set up dynamic provisioning.
Here is the configuration file for the hostPath PersistentVolume
The configuration file specifies that the volume is at /mnt/data on the cluster's Node. The configuration also specifies a size of 10 gibibytes and an access mode of ReadWriteOnce, which means the volume can be mounted as read-write by a single Node. It defines the StorageClass name manual for the PersistentVolume, which will be used to bind PersistentVolumeClaim requests to this PersistentVolume.
This example uses the ReadWriteOnce access mode, for simplicity. For production use, the Kubernetes project recommends using the ReadWriteOncePod access mode instead.
Create the PersistentVolume
Bounded code example (external data; do not execute automatically):
```shell
kubectl apply -f https://k8s.io/examples/pods/storage/pv-volume.yaml
```
View information about the PersistentVolume
Bounded code example (external data; do not execute automatically):
```shell
kubectl get pv task-pv-volume
```
The output shows that the PersistentVolume has a STATUS of Available. This means it has not yet been bound to a PersistentVolumeClaim.
