Custom Metrics in HPA. Custom metrics are user-defined performance indicators that extend the default resource metrics (e.g., CPU and memory) supported by the Horizontal Pod Autoscaler (HPA) in Kubernetes. By default, HPA bases its scaling decisions on pod resource requests, which represent the minimum resources required …

kubectl apply -f aks-store-quickstart-hpa.yaml Check the status of the autoscaler using the kubectl get hpa command. kubectl get hpa After a few minutes, with minimal load on the Azure Store Front app, the number of pod replicas decreases to three. You can use kubectl get pods again to see the unneeded pods being removed.5 days ago · Horizontal Pod Autoscaler doesn't have a hard limit on the supported number of HPA objects. However, above a certain number of HPA objects, the period between HPA recalculations may become longer than the standard 15 seconds. GKE minor version 1.21 or earlier: recalculation period should stay within 15 seconds with up to 100 HPA objects.

Every 30 seconds, Kubernetes … Could kubernetes-cronhpa-controller and HPA work together? Yes and no is the answer. kubernetes-cronhpa-controller can work together with hpa. But if the desired replicas is independent. So when the HPA min replicas reached kubernetes-cronhpa-controller will ignore the replicas and scale down and later the HPA controller will scale it up. so, i expected the hpa of this pod (including 2 containers) is (1+2)/ (2+4) = 50%. but the actual result is close to (1+2)/4 = 75%. it seems the istio-proxy's cpu request is excluded from calculating cpu utilization of hpa. as i know, k8s get cpu requests from deployment, but actually for this sidecar auto injection case, the deployment yaml ...As the Kubernetes API evolves, APIs are periodically reorganized or upgraded.
