Functions

func BuildBrokenLinearFunction added in v1.21.0

func BuildBrokenLinearFunction(shape FunctionShape) func(int64) int64

BuildBrokenLinearFunction creates a function which is built using linear segments. Segments are defined via shape array. Shape[i].Utilization slice represents points on "Utilization" axis where different segments meet. Shape[i].Score represents function values at meeting points.

function f(p) is defined as:

shape[0].Score for p < shape[0].Utilization
shape[n-1].Score for p > shape[n-1].Utilization

and linear between points (p < shape[i].Utilization)

func DefaultNormalizeScore

func DefaultNormalizeScore(maxPriority int64, reverse bool, scores framework.NodeScoreList) *framework.Status

DefaultNormalizeScore generates a Normalize Score function that can normalize the scores to [0, maxPriority]. If reverse is set to true, it reverses the scores by subtracting it from maxPriority.

func DefaultSelector

DefaultSelector returns a selector deduced from the Services, Replication Controllers, Replica Sets, and Stateful Sets matching the given pod.

func GetPodServices

func GetPodServices(sl corelisters.ServiceLister, pod *v1.Pod) ([]*v1.Service, error)

GetPodServices gets the services that have the selector that match the labels on the given pod.

Types

type FunctionShape added in v1.21.0

type FunctionShape []FunctionShapePoint

FunctionShape represents a collection of FunctionShapePoint.

type FunctionShapePoint added in v1.21.0

type FunctionShapePoint struct {
	// Utilization is function argument.
	Utilization int64
	// Score is function value.
	Score int64
}

FunctionShapePoint represents a shape point.
