Functions

func QuantityAsFloat64

func QuantityAsFloat64(q resource.Quantity) float64

QuantityAsFloat64 returns a float64 representation of a quantity. We need our own function because q.AsApproximateFloat64 sometimes returns surprising results. For example, resource.MustParse("5188205838208Ki").AsApproximateFloat64() returns 0.004291583283300088, whereas this function returns 5.312722778324993e+15.

Types

type ComputeResources

type ComputeResources map[string]resource.Quantity

func CalculateTotalResource

func CalculateTotalResource(nodes []*v1.Node) ComputeResources

func CalculateTotalResourceRequest

func CalculateTotalResourceRequest(pods []*v1.Pod) ComputeResources

func FromResourceList

func FromResourceList(list v1.ResourceList) ComputeResources

func TotalPodResourceLimit

func TotalPodResourceLimit(podSpec *v1.PodSpec) ComputeResources

func TotalPodResourceRequest

func TotalPodResourceRequest(podSpec *v1.PodSpec) ComputeResources

TotalPodResourceRequest represents the resource request for a given pod is the maximum of:

• sum of all containers
• any individual init container

This is because:

• containers run in parallel (so need to sum resources)
• init containers run sequentially (so only their individual resource need be considered)

So pod resource usage is the max for each resource type (cpu/memory etc) that could be used at any given time
