In this situation you should check several places.Since kubernetes 1.16 there is a feature gate called HPAScaleToZero which enables setting minReplicas to 0 for HorizontalPodAutoscaler resources when using custom or external metrics. ... 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.Kubernetes HPA Limitations. HPA can’t be used along with Vertical Pod Autoscaler based on CPU or Memory metrics. VPA can only scale based on CPU and memory values, so when VPA is enabled, HPA must use one or more custom metrics to avoid a scaling conflict with VPA.

Horizontal, in this case, means that we're talking about scaling the number of pods. You can specify the minimum …Jul 19, 2021 · Cluster Autoscaling (CA) manages the number of nodes in a cluster. It monitors the number of idle pods, or unscheduled pods sitting in the pending state, and uses that information to determine the appropriate cluster size. Horizontal Pod Autoscaling (HPA) adds more pods and replicas based on events like sustained CPU spikes. Sep 13, 2022 · When to use Kubernetes HPA?
