Functions

func AccessModesContainedInAll

func AccessModesContainedInAll(indexedModes []v1.PersistentVolumeAccessMode, requestedModes []v1.PersistentVolumeAccessMode) bool

AccessModesContainedInAll returns whether all of the requested modes are contained by modes

func AccessModesContains

func AccessModesContains(modes []v1.PersistentVolumeAccessMode, mode v1.PersistentVolumeAccessMode) bool

AccessModesContains returns whether the requested mode is contained by modes

func CheckPersistentVolumeClaimModeBlock

func CheckPersistentVolumeClaimModeBlock(pvc *v1.PersistentVolumeClaim) bool

CheckPersistentVolumeClaimModeBlock checks VolumeMode. If the mode is Block, return true otherwise return false.

func RoundUpSize

func RoundUpSize(volumeSizeBytes int64, allocationUnitBytes int64) int64

RoundUpSize calculates how many allocation units are needed to accommodate a volume of given size. E.g. when user wants 1500MiB volume, while AWS EBS allocates volumes in gibibyte-sized chunks, RoundUpSize(1500 * 1024*1024, 1024*1024*1024) returns '2' (2 GiB is the smallest allocatable volume that can hold 1500MiB)

func RoundUpToGiB

func RoundUpToGiB(sizeBytes int64) int64

RoundUpToGiB rounds up given quantity upto chunks of GiB
