1 Answer. 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 criteria are met and ...Aug 31, 2018 · The Horizontal Pod Autoscaler and Kubernetes Metrics Server are now supported by Amazon Elastic Kubernetes Service (EKS).

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 ... cpu: 100m. limits: memory: 860Mi. cpu: 500m. The number of replicas of the deployment is like below. When I listed the hpa, it is showed like below. the output is like below. Eventhough the load is low, initially pod count is 4. But the given minimum pod is 2.Sorted by: 1. HPA is a namespaced resource. It means that it can only scale Deployments which are in the same Namespace as the HPA itself. That's why it is only working when both HPA and Deployment are in the namespace: rabbitmq. You can check it within your cluster by running: Any HPA target can be scaled based on the resource usage of the pods in the scaling target.When defining the pod specification the resource requests like cpu and memory shouldbe specified. This is used to determine the resource utilization and used by the HPA controllerto scale the target up or down.
