Oct 9, 2023 · Horizontal scaling is the most basic autoscaling pattern in Kubernetes. HPA sets two parameters: the target utilization level and the minimum or maximum number of replicas allowed. When the utilization of a pod exceeds the target, HPA will automatically scale up the number of replicas to handle the increased load.

Essencialmente o controlador HPA obter métricas de três APIs diferentes: metrics.k8s.io, custom.metrics.k8s.io e external.metrics.k8s.io . Para métricas personalizadas e externas, a API é implementada por um fornecedor de terceiros ou você pode criar sua própria API. Neste caso usaremos o adaptador prometheus que …Behind the scenes, KEDA acts to monitor the event source and feed that data to Kubernetes and the HPA (Horizontal Pod Autoscaler) to drive the rapid scale of a resource. Each replica of a resource is actively pulling items from the event source. KEDA also supports the scaling behavior that we configure in Horizontal Pod Autoscaler.The Horizontal Pod Autoscaler and Kubernetes Metrics Server are now supported by Amazon Elastic Kubernetes Service (EKS).

Kubernetes’ default HPA is based on CPU utilization and desiredReplicas never go lower than 1, where CPU utilization cannot be zero for a running Pod.

The way the HPA controller calculates the number of replicas is. desiredReplicas = ceil[currentReplicas * ( currentMetricValue / desiredMetricValue )] In your case the currentMetricValue is calculated from the average of the given metric across the pods, so (463 + 471)/2 = 467Mi because of the targetAverageValue being set.
