Mar 18, 2024 · Replace HPA_NAME with the name of your HorizontalPodAutoscaler object. If the Horizontal Pod Autoscaler uses apiVersion: autoscaling/v2 and is based on multiple metrics, the kubectl describe hpa command only shows the CPU metric. To see all metrics, use the following command instead: kubectl describe hpa.v2.autoscaling HPA_NAME
Sorted by: 1. As Zerkms has said the resource limit is per container. Something else to note: the resource limit will be used for Kubernetes to evict pods and for assigning pods to nodes. For example if it is set to 1024Mi and it consumes 1100Mi, Kubernetes knows it may evict that pod. If the HPA plus the current scaling metric …

I have Kubernetes cluster hosted in Google Cloud. I created a deployment and defined a hpa rule for it: kubectl autoscale deployment my_deployment --min 6 --max 30 --cpu-percent 80. I want to run a command that editing the --min value, without remove and re-create a new hpa rule.HPA's native integration with Kubernetes makes it a straightforward choice, without the need for the more complex setup that KEDA might require. 3. Stateless Microservices Scenario: You're running a set of stateless microservices that handle tasks like authentication, logging, or caching.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.
