APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources |
|
|
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds |

deletionPolicy

volumeGroupSnapshotRef
Property | Type | 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. |
|
|
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. |
|
|
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. |
|
|
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. |
|
|
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. |

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. |
|
|
VolumeHandles is a list of volume handles on the backend to be snapshotted together. It is specified for dynamic provisioning of the VolumeGroupSnapshot. This field is immutable. |
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.

API version of the referent. |
|
|
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. |

|
CreationTime is the timestamp when the point-in-time group snapshot is taken by the underlying storage system. If not specified, it indicates the creation time is unknown. If not specified, it means the readiness of a group snapshot is unknown. The format of this field is a Unix nanoseconds time encoded as an int64. On Unix, the command date +%s%N returns the current time in nanoseconds since 1970-01-01 00:00:00 UTC. |
|
|
Error is the last observed error during group snapshot creation, if any. Upon success after retry, this error field will be cleared. |
|
|
PVVolumeSnapshotContentList is the list of pairs of PV and VolumeSnapshotContent for this group snapshot The maximum number of allowed snapshots in the group is 100. |
|
|
PVVolumeSnapshotContentPair represent a pair of PV names and VolumeSnapshotContent names |
|
|
ReadyToUse indicates if all the individual snapshots in the group are ready to be used to restore a group of volumes. ReadyToUse becomes true when ReadyToUse of all individual snapshots become true. |
|
|
VolumeGroupSnapshotHandle is a unique id returned by the CSI driver to identify the VolumeGroupSnapshot on the storage system. If a storage system does not provide such an id, the CSI driver can choose to return the VolumeGroupSnapshot name. |
Error is the last observed error during group snapshot creation, if any. Upon success after retry, this error field will be cleared.

When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed |
|
|
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. |
