1. HPA is used to scale more pods when pod loads are high, but this won't increase the resources on your cluster. I think you're looking for cluster autoscaler (works on AWS, GKE and Azure) and will increase cluster capacity when pods can't be scheduled. Share. Improve this answer.

There are three main types of elastic scaling in Kubernetes: HPA, VPA, and CA. Here we will focus on Pod Horizontal Scaling HPA. With the release of Kubernetes v1.23, the HPA API came to a stable version autoscaling/v2: Scaling based on custom metrics Scaling based on multiple metrics Configurable scaling behaviour From the initial …Sep 14, 2021 · type=AverageValue && averageValue: 500Mi. averageValue is the target value of the average of the metric across all relevant pods (as a quantity) so my memory metric for HPA turned out to become: apiVersion: autoscaling/v2beta2. kind: HorizontalPodAutoscaler. metadata: name: backend-hpa. spec: Overview. KEDA (Kubernetes-based Event-driven Autoscaling) is an open source component developed by Microsoft and Red Hat to allow any Kubernetes workload to benefit from the event-driven architecture model.

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.HPA uses the custom.metrics.k8s.io API to consume these metrics. This API is enabled by deploying a custom metrics adapter for the metrics collection solution. For this example, we are going to use Prometheus. We are beginning with the following assumptions:The HPA --horizontal-pod-autoscaler-sync-period is set to 15 seconds on GKE and can't be changed as far as I know. My custom metrics are updated every 30 seconds. I believe that what causes this behavior is that when there is a high message count in the queues every 15 seconds the HPA triggers a scale up and after few cycles it …The Horizontal Pod Autoscaler (HPA) scales the number of pods of a replica-set/ deployment/ statefulset based on per-pod metrics received from resource metrics API (metrics.k8s.io) provided by metrics-server, the custom metrics API (custom.metrics.k8s.io), or the external metrics API (external.metrics.k8s.io).

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. 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 …The Vertical Pod Autoscaler vpa-recommender deployment analyzes the hamster Pods to see if the CPU and memory requirements are appropriate.
