Deleting a PVC (to be discarded)

Function

This API is used to delete a PVC from a specified namespace. Using this API, you can determine whether to retain the cloud storage volume associated with the PVC. This API has been deprecated. Use the corresponding Kubernetes PV API instead.

The URL for storage management is in the format of https://{clusterid}.Endpoint/uri. In the URL, {clusterid} indicates the cluster ID, and uri indicates the resource path, that is, the path for API access. If https://Endpoint/uri is used, the X-Cluster-ID parameter in the request header must be specified.

Calling Method

For details, see Calling APIs.

URI

DELETE /api/v1/namespaces/{namespace}/cloudpersistentvolumeclaims/{name}

Parameter

Mandatory

Type

Description

Content-Type

Yes

String

Message body type (format).

X-Auth-Token

Table 5 PersistentVolumeClaimMetadata

Parameter

Type

Description

name

String

PVC name. Enter 1 to 253 characters starting and ending with a letter or digit. Only lowercase letters, digits, hyphens (-), and periods (.) are allowed. PVC names must be unique in a namespace.

labels

String

PVC labels, in the format of key-value pairs.

  • Key: Enter 1 to 63 characters, starting with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed. A DNS subdomain can be prefixed to a key and contain a maximum of 253 characters. Example DNS subdomain: example.com/my-key

Table 6 PersistentVolumeClaimSpec

Parameter

Type

Description

volumeID

String

ID of an existing storage volume.

  • If an SFS, EVS, or SFS Turbo volume is used, set this parameter to the ID of the volume.

  • If an OBS bucket is used, set this parameter to the OBS bucket name.

storageType

String

Cloud storage class. This parameter is used together with volumeID. That is, volumeID and storageType must be configured at the same time.

  • bs: EVS

  • nfs: SFS

  • obs: OBS

  • efs: SFS Turbo

accessModes

Array of strings

Access mode of the volume. Only the first value in all selected options is valid.

  • ReadWriteOnce: The volume can be mounted as read-write by a single node.

    NOTE:

    This function is supported only when the cluster version is v1.13.10 and the storage-driver version is 1.0.19.

  • ReadOnlyMany (default): The volume can be mounted as read-only by many nodes.

  • ReadWriteMany: The volume can be mounted as read-write by many nodes.

storageClassName

String

Storage class name of the PVC.

volumeName

String

Name of the PV bound to the PVC.

resources

ResourceRequirements object

Resource requests and limits.

volumeMode

String

PV type specified by the PVC.

Table 7 ResourceRequirements

Parameter

Type

Description

limits

Map<String,String>

Resource limits. This parameter is invalid during creation.

requests

Map<String,String>

Resource requests. This parameter is invalid during creation.

Table 8 PersistentVolumeClaimStatus
