# How to clone an image from one block raw PV to another one
|
|
The purpose of this document is to show how to clone an image from an existing raw block PV, to another target block PV.
|
|
|
|
## Prerequisites
|
|
- You have a Kubernetes cluster up and running with CDI installed, block source PVC, and at least one available block PersistentVolume to store the cloned disk image.
|
|
- Feature-Gate 'BlockVolume' is enabled.
|
|
|
|
|
|
## Clone an image with DataVolume manifest
|
|
|
|
Create the following DataVolume manifest (clone-block-datavolume.yaml):
|
|
|
|
```yaml
|
|
apiVersion: cdi.kubevirt.io/v1beta1
|
|
kind: DataVolume
|
|
metadata:
|
|
name: clone-block-datavolume
|
|
spec:
|
|
source:
|
|
pvc:
|
|
namespace: "source-ns"
|
|
name: "source-datavolume"
|
|
pvc:
|
|
volumeMode: Block
|
|
accessModes:
|
|
- ReadWriteOnce
|
|
resources:
|
|
requests:
|
|
storage: 1Gi
|
|
```
|
|
|
|
Deploy the DataVolume manifest:
|
|
|
|
```bash
|
|
kubectl create -f clone-block-pv-datavolume.yaml
|
|
```
|
|
|
|
Two cloning pods, source and target, will be spawned and the image existed on the source block PV, will be copied to the target block PV.
