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
