Functions

func ChooseZonesForVolume

func ChooseZonesForVolume(zones sets.String, pvcName string, numZones uint32) sets.String

ChooseZonesForVolume is identical to ChooseZoneForVolume, but selects a multiple zones, for multi-zone disks.

func LabelZonesToList

func LabelZonesToList(labelZonesValue string) ([]string, error)

LabelZonesToList converts a PV label value from string containing a delimited list of zones to list

func LabelZonesToSet

func LabelZonesToSet(labelZonesValue string) (sets.String, error)

LabelZonesToSet converts a PV label value from string containing a delimited list of zones to set

func RoundUpToGB

func RoundUpToGB(size resource.Quantity) int64

RoundUpToGB rounds up given quantity to chunks of GB

func RoundUpToGBInt

RoundUpToGiB rounds up given quantity upto chunks of GiB

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 RoundUpToKB

func RoundUpToKB(size resource.Quantity) int64

RoundUpToKB rounds up given quantity to chunks of KB

func RoundUpToKBInt

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

RoundUpToKBInt rounds up given quantity to chunks of KB. It returns an int instead of an int64 and an error if there's overflow

func RoundUpToKiB

func RoundUpToKiB(size resource.Quantity) int64

RoundUpToKiB rounds up given quantity upto chunks of KiB

func RoundUpToKiBInt

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

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

func SelectZoneForVolume

func SelectZoneForVolume(zoneParameterPresent, zonesParameterPresent bool, zoneParameter string, zonesParameter, zonesWithNodes sets.String, node *v1.Node, allowedTopologies []v1.TopologySelectorTerm, pvcName string) (string, error)

SelectZoneForVolume is a wrapper around SelectZonesForVolume to select a single zone for a volume based on parameters

func SelectZonesForVolume

func SelectZonesForVolume(zoneParameterPresent, zonesParameterPresent bool, zoneParameter string, zonesParameter, zonesWithNodes sets.String, node *v1.Node, allowedTopologies []v1.TopologySelectorTerm, pvcName string, numReplicas uint32) (sets.String, error)

SelectZonesForVolume selects zones for a volume based on several factors: node.zone, allowedTopologies, zone/zones parameters from storageclass, zones with active nodes from the cluster. The number of zones = replicas.

func ZonesFromAllowedTopologies

func ZonesFromAllowedTopologies(allowedTopologies []v1.TopologySelectorTerm) (sets.String, error)

ZonesFromAllowedTopologies returns a list of zones specified in allowedTopologies
