CreateUploadPod creates upload service pod manifest and sends to server

func CreateUploadService 

func CreateUploadService(client kubernetes.Interface, name string, pvc *v1.PersistentVolumeClaim) (*v1.Service, error)

CreateUploadService creates upload service service manifest and sends to server

func GetUploadResourceName 

func GetUploadResourceName(pvcName string) string

GetUploadResourceName returns the name given to upload services/pods

func MakeCloneSourcePodSpec 

func MakeCloneSourcePodSpec(image, pullPolicy, sourcePvcName string, pvc *v1.PersistentVolumeClaim) *v1.Pod

MakeCloneSourcePodSpec creates and returns the clone source pod spec based on the target pvc.

func MakeCloneTargetPodSpec 

func MakeCloneTargetPodSpec(image, pullPolicy, podAffinityNamespace string, pvc *v1.PersistentVolumeClaim) *v1.Pod

MakeCloneTargetPodSpec creates and returns the clone target pod spec based on the target pvc.

func MakeImporterPodSpec 

func MakeImporterPodSpec(image, verbose, pullPolicy string, podEnvVar *importPodEnvVar, pvc *v1.PersistentVolumeClaim) *v1.Pod

MakeImporterPodSpec creates and return the importer pod spec based on the passed-in endpoint, secret and pvc.

func MakePVCOwnerReference added in v1.5.1 

func MakePVCOwnerReference(pvc *v1.PersistentVolumeClaim) metav1.OwnerReference
