func CreateCPUHorizontalPodAutoscaler Uses

❖
func CreateCPUHorizontalPodAutoscaler(rc *ResourceConsumer, cpu, minReplicas, maxRepl int32) *autoscalingv1.HorizontalPodAutoscaler

CreateCPUHorizontalPodAutoscaler create a horizontalPodAutoscaler with CPU target for consuming resources.

func DeleteHorizontalPodAutoscaler Uses

❖
func DeleteHorizontalPodAutoscaler(rc *ResourceConsumer, autoscalerName string)

DeleteHorizontalPodAutoscaler delete the horizontalPodAutoscaler for consuming resources.

type ResourceConsumer Uses

❖
type ResourceConsumer struct {
    // contains filtered or unexported fields
}

ResourceConsumer is a tool for testing. It helps create specified usage of CPU or memory (Warning: memory not supported) typical use case: rc.ConsumeCPU(600) // ... check your assumption here rc.ConsumeCPU(300) // ... check your assumption here

func NewDynamicResourceConsumer Uses

❖
func NewDynamicResourceConsumer(name, nsName string, kind schema.GroupVersionKind, replicas, initCPUTotal, initMemoryTotal, initCustomMetric int, cpuLimit, memLimit int64, clientset clientset.Interface, scaleClient scaleclient.ScalesGetter) *ResourceConsumer

NewDynamicResourceConsumer is a wrapper to create a new dynamic ResourceConsumer

func (*ResourceConsumer) CleanUp Uses

❖
func (rc *ResourceConsumer) CleanUp()

❖
func (rc *ResourceConsumer) GetReplicas() int

GetReplicas get the replicas

func (*ResourceConsumer) Pause Uses

❖
func (rc *ResourceConsumer) Pause()

Pause stops background goroutines responsible for consuming resources.

func (*ResourceConsumer) Resume Uses

❖
