type: object
spec:
description: |-
Spec defines properties of a VolumeGroupSnapshotContent created by the underlying storage system.
Required.
properties:
deletionPolicy:
description: |-
DeletionPolicy determines whether this VolumeGroupSnapshotContent and the
physical group snapshot on the underlying storage system should be deleted
when the bound VolumeGroupSnapshot is deleted.
Supported values are "Retain" and "Delete".
"Retain" means that the VolumeGroupSnapshotContent and its physical group
snapshot on underlying storage system are kept.
"Delete" means that the VolumeGroupSnapshotContent and its physical group
snapshot on underlying storage system are deleted.
For dynamically provisioned group snapshots, this field will automatically
be filled in by the CSI snapshotter sidecar with the "DeletionPolicy" field
defined in the corresponding VolumeGroupSnapshotClass.
For pre-existing snapshots, users MUST specify this field when creating the
VolumeGroupSnapshotContent object.
Required.
enum:
- Delete
- Retain
type: string
driver:
description: |-
Driver is the name of the CSI driver used to create the physical group snapshot on
the underlying storage system.
This MUST be the same as the name returned by the CSI GetPluginName() call for
that driver.
Required.
type: string
source:
description: |-
Source specifies whether the snapshot is (or should be) dynamically provisioned
or already exists, and just requires a Kubernetes object representation.
This field is immutable after creation.
Required.
properties:
groupSnapshotHandles:

GroupSnapshotHandles specifies the CSI "group_snapshot_id" of a pre-existing
group snapshot and a list of CSI "snapshot_id" of pre-existing snapshots
on the underlying storage system for which a Kubernetes object
representation was (or should be) created.
This field is immutable.
properties:
volumeGroupSnapshotHandle:
description: |-
VolumeGroupSnapshotHandle specifies the CSI "group_snapshot_id" of a pre-existing
group snapshot on the underlying storage system for which a Kubernetes object
representation was (or should be) created.
This field is immutable.
Required.
type: string
volumeSnapshotHandles:
description: |-
VolumeSnapshotHandles is a list of CSI "snapshot_id" of pre-existing
snapshots on the underlying storage system for which Kubernetes objects
representation were (or should be) created.

volumeGroupSnapshotClassName:
description: |-
VolumeGroupSnapshotClassName is the name of the VolumeGroupSnapshotClass from
which this group snapshot was (or will be) created.
Note that after provisioning, the VolumeGroupSnapshotClass may be deleted or
recreated with different set of values, and as such, should not be referenced
post-snapshot creation.
For dynamic provisioning, this field must be set.
This field may be unset for pre-provisioned snapshots.
type: string
volumeGroupSnapshotRef:
description: |-
VolumeGroupSnapshotRef specifies the VolumeGroupSnapshot object to which this
VolumeGroupSnapshotContent object is bound.
VolumeGroupSnapshot.Spec.VolumeGroupSnapshotContentName field must reference to
this VolumeGroupSnapshotContent's name for the bidirectional binding to be valid.
For a pre-existing VolumeGroupSnapshotContent object, name and namespace of the
VolumeGroupSnapshot object MUST be provided for binding to happen.
This field is immutable after creation.
Required.
properties:
apiVersion:
description: API version of the referent.
type: string
fieldPath:
description: |-
If referring to a piece of an object instead of an entire object, this string
should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2].
For example, if the object reference is to a container within a pod, this would take on a value like:
"spec.containers{name}" (where "name" refers to the name of the container that triggered
the event) or if no container name is specified "spec.containers[2]" (container with
index 2 in this pod). This syntax is chosen only to have some well-defined way of
referencing a part of an object.
TODO: this design is not final and this field is subject to change in the future.
