Deleting a PVC

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.

Note

The format of the storage management API URL is 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.

URI

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

Table 1 URI parameters
Parameter	Mandatory	Type	Description
name	Yes	String	Name of the PVC to be deleted. Name format: Volume name[?deleteVolume=BOOLEAN&storageType=Cloud storage volume type]. The square brackets and the content in it can be omitted. Example: volume-49f1?deleteVolume=true&storageType=bs volume-49f1 Specifically: deleteVolume: Whether to delete associated backend cloud storage volume after the PVC is deleted. The value can be true (delete) or false (not delete). The value defaults to false. NOTE: If the storage volume type is efs, this parameter must be set to false. storageType: Cloud storage volume type. This parameter is used together with deleteVolume. That is, deleteVolume and storageType must be configured at the same time. bs: EVS nfs: SFS obs: OBS efs: SFS Turbo
namespace	Yes	String	Namespace where the PVC is located.

Request Parameters

Table 2 Request header parameters
Parameter	Mandatory	Type	Description
Content-Type	Yes	String	Message body type (format). Default value: application/json
X-Auth-Token	Yes	String	Requests for calling an API can be authenticated using either a token or AK/SK. If token-based authentication is used, this parameter is mandatory and must be set to a user token. For details on how to obtain a user token, see Token-based Authentication. Maximum length: 16,384 characters
X-Cluster-ID	No	String	Cluster ID. This parameter is mandatory when the URL format https://Endpoint/uri is used. For details about how to obtain the value, see How to Obtain Parameters in the API URI.

Response Parameters

Status code: 200

Table 3 Parameters in the response body
Parameter	Type	Description
apiVersion	String	API version. The value is fixed at v1. Default value: v1
kind	String	API type. The value is fixed at PersistentVolumeClaim. Default value: PersistentVolumeClaim
metadata	PersistentVolumeClaimMetadata object	Cluster object metadata, which is a collection of attributes.
spec	PersistentVolumeClaimSpec object	Detailed description of the cluster object. CCE creates or updates objects by defining or updating spec.
status	PersistentVolumeClaimStatus object	PVC status. The request to create a PVC does not need to carry this parameter.

Table 4 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 Value: The value can be left blank or a string of 1 to 63 characters starting with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed in the character string.

Table 5 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. Options: ReadOnlyMany ReadWriteMany
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 6 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 7 PersistentVolumeClaimStatus
Parameter	Type	Description
accessModes	Array of strings	Access mode of the PersistentVolume.
capacity	String	Actual resources and capacity of the persistent volume.
phase	String	Current status of the PVC.
