Constants ¶

const AlphaStorageClassAnnotation = "volume.alpha.kubernetes.io/storage-class"

AlphaStorageClassAnnotation represents the previous alpha storage class annotation. it's no longer used and held here for posterity.

const BetaIsDefaultStorageClassAnnotation = "storageclass.beta.kubernetes.io/is-default-class"

const BetaStorageClassAnnotation = "volume.beta.kubernetes.io/storage-class"

BetaStorageClassAnnotation represents the beta/previous StorageClass annotation. It's currently still used and will be held for backwards compatibility

const IsDefaultStorageClassAnnotation = "storageclass.beta.kubernetes.io/is-default-class"

IsDefaultStorageClassAnnotation represents a StorageClass annotation that marks a class as the default StorageClass TODO: Update IsDefaultStorageClassannotation and remove Beta when no longer used

const StorageClassAnnotation = "volume.beta.kubernetes.io/storage-class"

StorageClassAnnotation represents the storage class associated with a resource. It currently matches the Beta value and can change when official is set.

• in PersistentVolumeClaim it represents required class to match. Only PersistentVolumes with the same class (i.e. annotation with the same value) can be bound to the claim. In case no such volume exists, the controller will provision a new one using StorageClass instance with the same name as the annotation value.
• in PersistentVolume it represents storage class to which the persistent volume belongs.

TODO: Update this to final annotation value as it matches BetaStorageClassAnnotation for now

Functions ¶

func GetClaimStorageClass ¶

func GetClaimStorageClass(claim *api.PersistentVolumeClaim) string

GetClaimStorageClass returns name of class that is requested by given claim. Request for `nil` class is interpreted as request for class "", i.e. for a classless PV. TODO: change to PersistentVolumeClaim.Spec.Class value when this attribute is introduced.

func GetStorageClassAnnotation ¶

func GetStorageClassAnnotation(obj api.ObjectMeta) string

GetStorageClassAnnotation returns the StorageClass value if the annotation is set, empty string if not TODO: remove Alpha and Beta when no longer used or needed

func GetVolumeStorageClass ¶

func GetVolumeStorageClass(volume *api.PersistentVolume) string

GetVolumeStorageClass returns value of StorageClassAnnotation or empty string in case the annotation does not exist. TODO: change to PersistentVolume.Spec.Class value when this attribute is introduced.

func HasStorageClassAnnotation ¶

func HasStorageClassAnnotation(obj api.ObjectMeta) bool

HasStorageClassAnnotation returns a boolean if the annotation is set TODO: remove Alpha and Beta when no longer used or needed

func IsDefaultAnnotation ¶

func IsDefaultAnnotation(obj api.ObjectMeta) bool

IsDefaultAnnotation returns a boolean if the annotation is set TODO: remove Beta when no longer needed

func IsDefaultAnnotationText ¶

func IsDefaultAnnotationText(obj api.ObjectMeta) string

IsDefaultAnnotationText returns a pretty Yes/No String if the annotation is set TODO: remove Beta when no longer needed
