Chapter 12. VolumeSnapshotClass [snapshot.storage.k8s.io/v1] Description VolumeSnapshotClass specifies parameters that a underlying storage system uses when creating a volume snapshot. A specific VolumeSnapshotClass is used by specifying its name in a VolumeSnapshot object. VolumeSnapshotClasses are non-namespaced Type object Required deletionPolicy driver 12.1. Specification Property Type Description apiVersion string 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 deletionPolicy string deletionPolicy determines whether a VolumeSnapshotContent created through the VolumeSnapshotClass should be deleted when its bound VolumeSnapshot is deleted. Supported values are "Retain" and "Delete". "Retain" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are kept. "Delete" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are deleted. Required. driver string driver is the name of the storage driver that handles this VolumeSnapshotClass. Required. kind string 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 metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata parameters object (string) parameters is a key-value map with storage driver specific parameters for creating snapshots. These values are opaque to Kubernetes. 12.2. API endpoints The following API endpoints are available: /apis/snapshot.storage.k8s.io/v1/volumesnapshotclasses DELETE : delete collection of VolumeSnapshotClass GET : list objects of kind VolumeSnapshotClass POST : create a VolumeSnapshotClass /apis/snapshot.storage.k8s.io/v1/volumesnapshotclasses/{name} DELETE : delete a VolumeSnapshotClass GET : read the specified VolumeSnapshotClass PATCH : partially update the specified VolumeSnapshotClass PUT : replace the specified VolumeSnapshotClass 12.2.1. /apis/snapshot.storage.k8s.io/v1/volumesnapshotclasses HTTP method DELETE Description delete collection of VolumeSnapshotClass Table 12.1. HTTP responses HTTP code Reponse body 200 - OK Status schema 401 - Unauthorized Empty HTTP method GET Description list objects of kind VolumeSnapshotClass Table 12.2. HTTP responses HTTP code Reponse body 200 - OK VolumeSnapshotClassList schema 401 - Unauthorized Empty HTTP method POST Description create a VolumeSnapshotClass Table 12.3. Query parameters Parameter Type Description dryRun string 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 string 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. Table 12.4. Body parameters Parameter Type Description body VolumeSnapshotClass schema Table 12.5.
