Also as @mdaniel adviced you may follow this issue of scheduler. See also similar problem: scaling-deployment-kubernetes.O Kubernetes usa o HPA (dimensionador automático de pod horizontal) para monitorar a demanda por recursos e dimensionar automaticamente o número de pods. Por padrão, a cada 15 segundos o HPA verifica se há alguma alteração necessárias na contagem de réplicas da API de Métricas, e a API de Métricas recupera dados do Kubelet a cada 60 …

As of kubernetes 1.9 HPA calculates pod cpu utilization as total cpu usage of all containers in pod divided by total request. So in your example the calculated usage would be 133%. I don't think that's specified in docs anywhere, but the relevant code is here: ...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.1 Answer. create a monitor of Kotlin coroutines into code and when the Kubernetes make the health check it checks the status of my coroutines.

I am facing the same issue as described here: Kubernetes deployment not scaling down even though usage is below threshold. My configuration is almost identical. I have checked the hpa algorithm, but I cannot find an explanation for the fact that I am having only one replica of my-app3.

The main purpose of HPA is to automatically scale your deployments based on the load to match the demand. Horizontal, in this case, means that we're talking about scaling the number of pods. You can specify the minimum …

1. HPA main goal is to spawn more pods to keep average load for a group of pods on specified level. HPA is not responsible for Load Balancing and equal connection distribution. For equal connection distribution is responsible k8s service, which works by deafult in iptables mode and - according to k8s docs - it picks pods by random.

Is there a way for HPA to scale-down based on a different counter, something like active connections. Only when active connections reach 0, the pod is deleted.

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 …4 - Kubernetes waits for a grace period. At this point, Kubernetes waits for a specified time called the termination grace period. By default, this is 30 seconds.

Nov 2, 2022 · The HPA is included with Kubernetes out of the box. It is a controller, which means it works by continuously watching and mutating Kubernetes API resources. In this particular case, it reads HorizontalPodAutoscaler resources for configuration values, and calculates how many pods to run for associated Deployment objects. external metrics: custom metrics not associated with a Kubernetes object. Any HPA target can be scaled based on the resource usage of the pods (or containers) in the scaling target. The CPU utilization metric is a resource metric, you can specify other resource metrics besides CPU (e.g. memory). This seems to be the easiest and most …By default, HPA in GKE uses CPU to scale up and down (based on resource requests Vs actual usage). However, you can use custom metrics as well, just follow this guide. In your case, have the custom metric track the number of HTTP requests per pod (do not use the number of requests to the LB). Make sure when using custom metrics, that …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.
