To enable snapshot functionality system does require snapshot |CRD| and
|
||||
snapshot controller to be created on system. Follow the steps below:
|
||||
|
||||
#. Run to install snapshot |CRD| and snapshot controller on Kubernets:
|
||||
|
||||
- ``kubectl apply -f`` https://raw.githubusercontent.com/kubernetes-csi/external-snapshotter/master/client/config/crd/snapshot.storage.k8s.io_volumesnapshots.yaml

.. note::
|

|

It is necessary that the |CRDs| and snapshot-controller running pod are
|
||||
present in the system to create the Volume Snapshot Class. The |CRDs| and
|
||||
snapshot-controller are created by default during installation when running
|
||||
the bootstrap playbook.
