var (

	// AnnPreResizeCapacity annotation is added to a PV when expanding volume.
	// Its value is status capacity of the PVC prior to the volume expansion
	// Its value will be set by the external-resizer when it deems that filesystem resize is required after resizing volume.
	// Its value will be used by pv_controller to determine pvc's status capacity when binding pvc and pv.

Functions ¶

func GetPVCPatchData ¶ added in v1.0.0

func GetPVCPatchData(oldPVC, newPVC *v1.PersistentVolumeClaim) ([]byte, error)

func GetPatchData ¶ added in v1.0.0

func GetPatchData(oldObj, newObj interface{}) ([]byte, error)

func HasFileSystemResizePendingCondition ¶

func HasFileSystemResizePendingCondition(pvc *v1.PersistentVolumeClaim) bool

HasFileSystemResizePendingCondition returns true if a pvc has a FileSystemResizePending condition. This means the controller side resize operation is finished, and kubelet side operation is in progress.

func MergeResizeConditionsOfPVC ¶

func MergeResizeConditionsOfPVC(oldConditions, newConditions []v1.PersistentVolumeClaimCondition) []v1.PersistentVolumeClaimCondition

MergeResizeConditionsOfPVC updates pvc with requested resize conditions leaving other conditions untouched.

func PVCKey ¶

func PVCKey(pvc *v1.PersistentVolumeClaim) string

PVCKey returns an unique key of a PVC object,

func SanitizeName ¶

func SanitizeName(name string) string
