CloneStrategyByProvisionerKey defines the advised clone strategy for a provisioner

	"rook-ceph.rbd.csi.ceph.com":         cdiv1.DataImportCronSourceFormatSnapshot,

	"csi.trident.netapp.io/ontap-san":    cdiv1.DataImportCronSourceFormatSnapshot,
}

SourceFormatsByProvisionerKey defines the advised data import cron source format Certain storage provisioners will scale better cloning from a single source VolumeSnapshot source

var UnsupportedProvisioners = map[string]struct{}{
	ProvisionerOCSBucket:      {},
	ProvisionerRookCephBucket: {},
	ProvisionerNoobaa:         {},
	ProvisionerStorkSnapshot:  {},
}

UnsupportedProvisioners is a hash of provisioners which are known not to work with CDI

Functions

func GetAdvisedCloneStrategy

func GetAdvisedCloneStrategy(sc *storagev1.StorageClass) (cdiv1.CDICloneStrategy, bool)

GetAdvisedCloneStrategy finds and returns the advised clone strategy

func GetAdvisedSourceFormat

func GetAdvisedSourceFormat(sc *storagev1.StorageClass) (cdiv1.DataImportCronSourceFormat, bool)

GetAdvisedSourceFormat finds and returns the advised format for dataimportcron sources

Types

type StorageCapabilities

type StorageCapabilities struct {
	AccessMode v1.PersistentVolumeAccessMode
	VolumeMode v1.PersistentVolumeMode
}

StorageCapabilities is a simple holder of storage capabilities (accessMode etc.)

func GetCapabilities

func GetCapabilities(cl client.Client, sc *storagev1.StorageClass) ([]StorageCapabilities, bool)

GetCapabilities finds and returns a predefined StorageCapabilities for a given StorageClass
