Functions

func GetScaleBounds

func GetScaleBounds(asConfig *autoscalerconfig.Config, pa *autoscalingv1alpha1.PodAutoscaler,
	spa *autoscalingv1.StagePodAutoscaler) (int32, int32)

GetScaleBounds returns the min and the max scales for the current stage.

func NewController

func NewController(
	ctx context.Context,
	cmw configmap.Watcher,
	deciders resources.Deciders,
) *controller.Impl

NewController returns a new KPA reconcile controller. TODO(mattmoor): Fix the signature to adhere to the injection type.

Types

type Reconciler

type Reconciler struct {
	*areconciler.Base
	// contains filtered or unexported fields
}

Reconciler tracks PAs and right sizes the ScaleTargetRef based on the information from Deciders.

func (*Reconciler) ObserveDeletion

func (c *Reconciler) ObserveDeletion(ctx context.Context, key types.NamespacedName) error

ObserveDeletion implements OnDeletionInterface.ObserveDeletion.

func (*Reconciler) ReconcileKind

func (c *Reconciler) ReconcileKind(ctx context.Context, pa *autoscalingv1alpha1.PodAutoscaler) pkgreconciler.Event

ReconcileKind implements Interface.ReconcileKind.
