Functions

func Contains

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

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

func CutString255

func CutString255(original string) string

CutString255 makes sure the string length doesn't exceed 255, which is usually the maximum string length in OpenStack.

func GetAZFromTopology

func GetAZFromTopology(topologyKey string, requirement *csi.TopologyRequirement) string

func PatchService

func PatchService(ctx context.Context, client clientset.Interface, cur, mod *v1.Service) error

PatchService makes patch request to the Service object.

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 Sprintf255

func Sprintf255(format string, args ...interface{}) string

Sprintf255 formats according to a format specifier and returns the resulting string with a maximum length of 255 characters.

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

Types

type MyDuration

type MyDuration struct {
	time.Duration
}

MyDuration is the encoding.TextUnmarshaler interface for time.Duration

func (*MyDuration) UnmarshalText

func (d *MyDuration) UnmarshalText(text []byte) error

UnmarshalText is used to convert from text to Duration
