Functions

func CreateEphemeralImages

func CreateEphemeralImages(
	vmi *v1.VirtualMachineInstance,
	diskCreator ephemeraldisk.EphemeralDiskCreatorInterface,
	disksInfo map[string]*DiskInfo,
) error

func ExtractImageIDsFromSourcePod

func ExtractImageIDsFromSourcePod(vmi *v1.VirtualMachineInstance, sourcePod *kubev1.Pod) (imageIDs map[string]string, err error)
