Functions

func MakeMetric

func MakeMetric(ctx context.Context, pa *v1alpha1.PodAutoscaler, metricSvc string,
	config *autoscaler.Config) *v1alpha1.Metric

MakeMetric constructs a Metric resource from a PodAutoscaler

func MakeMetricsService

func MakeMetricsService(pa *pav1alpha1.PodAutoscaler, selector map[string]string) *corev1.Service

MakeMetricsService constructs a service that can be scraped for metrics.

func MakeSKS

func MakeSKS(pa *pav1alpha1.PodAutoscaler, mode nv1a1.ServerlessServiceOperationMode) *nv1a1.ServerlessService

MakeSKS makes an SKS resource from the PA and operation mode.

func ResolveMetricTarget

func ResolveMetricTarget(pa *v1alpha1.PodAutoscaler, config *autoscaler.Config) (target float64, total float64)

ResolveMetricTarget takes scaling metric knobs from multiple locations and resolves them to the final value to be used by the autoscaler. `target` is the target value of scaling metric that we autoscaler will aim for; `total` is the maximum possible value of scaling metric that is permitted on the pod.

func StableWindow

func StableWindow(pa *v1alpha1.PodAutoscaler, config *autoscaler.Config) time.Duration

StableWindow returns the stable window for the revision from PA, if set, or systemwide default.
