Types ¶

type HorizontalController ¶

type HorizontalController struct {
	// contains filtered or unexported fields
}

func NewHorizontalController ¶

func NewHorizontalController(evtNamespacer unversionedcore.EventsGetter, scaleNamespacer unversionedextensions.ScalesGetter, hpaNamespacer unversionedautoscaling.HorizontalPodAutoscalersGetter, replicaCalc *ReplicaCalculator, resyncPeriod time.Duration) *HorizontalController

func (*HorizontalController) Run ¶

func (a *HorizontalController) Run(stopCh <-chan struct{})

type ReplicaCalculator ¶ added in v1.5.0

type ReplicaCalculator struct {
	// contains filtered or unexported fields
}

func NewReplicaCalculator ¶ added in v1.5.0

func NewReplicaCalculator(metricsClient metricsclient.MetricsClient, podsGetter unversionedcore.PodsGetter) *ReplicaCalculator

func (*ReplicaCalculator) GetMetricReplicas ¶ added in v1.5.0

func (c *ReplicaCalculator) GetMetricReplicas(currentReplicas int32, targetUtilization float64, metricName string, namespace string, selector labels.Selector) (replicaCount int32, utilization float64, timestamp time.Time, err error)

GetMetricReplicas calculates the desired replica count based on a target resource utilization percentage of the given resource for pods matching the given selector in the given namespace, and the current replica count

func (*ReplicaCalculator) GetResourceReplicas ¶ added in v1.5.0

func (c *ReplicaCalculator) GetResourceReplicas(currentReplicas int32, targetUtilization int32, resource api.ResourceName, namespace string, selector labels.Selector) (replicaCount int32, utilization int32, timestamp time.Time, err error)

GetResourceReplicas calculates the desired replica count based on a target resource utilization percentage of the given resource for pods matching the given selector in the given namespace, and the current replica count
