Functions

func Contains

func Contains(list []string, strToSearch string) bool

Contains searches if a string list contains the given string or not.

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 RoundUpSizeInt

func RoundUpSizeInt(volumeSizeBytes int64, allocationUnitBytes int64) (int, error)

RoundUpSizeInt calculates how many allocation units are needed to accommodate a volume of given size. It returns an int instead of an int64 and an error if there's overflow

func RoundUpToGiBInt

func RoundUpToGiBInt(size resource.Quantity) (int, error)

RoundUpToGiBInt rounds up given quantity upto chunks of GiB. It returns an int instead of an int64 and an error if there's overflow

func StringListEqual

func StringListEqual(list1, list2 []string) bool

StringListEqual compares two string list, returns true if they have the same items, order doesn't matter
