It can work alongside an HPA: when scaled to zero, the HPA ignores the Deployment; once scaled back to one, the HPA may scale up further. Share.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.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.Kubernetes HPA is flapping replicas regardless of stabilisation window.

HPA is a native Kubernetes resource that you can template out just like you have done for your other resources. Helm is both a package management system and a templating tool, but it is unlikely its docs contain specific examples for all Kubernetes API objects. You can see many examples of HPA templates in the Bitnami Helm Charts.

Creating the …Nov 13, 2023 · HPA is a Kubernetes component that automatically updates workload resources such as Deployments and StatefulSets, scaling them to match demand for applications in the cluster. Horizontal scaling means deploying more pods in response to increased load. It should not be confused with vertical scaling, which means allocating more Kubernetes node ... 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. As the Kubernetes API evolves, APIs are periodically reorganized or upgraded. When APIs evolve, the old API is deprecated and eventually removed.
