Komodor provides: Change intelligence: Every issue is a result of a change ...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). Fig:- Horizontal Pod Autoscaling.First, get the YAML of your HorizontalPodAutoscaler in the autoscaling/v2 form: kubectl get hpa php-apache -o yaml > /tmp/hpa-v2.yaml. Open the /tmp/hpa-v2.yaml file in an editor, and you should see YAML which looks like this:

Kubernetes autoscaling allows a cluster to automatically increase or decrease the number of nodes, or adjust pod resources, in response to demand. This can help optimize resource usage and costs, and also improve performance. Three common solutions for K8s autoscaling are HPA, VPA, and Cluster Autoscaler.2. This is typically related to the metrics server.

Kubernetes uses the horizontal pod autoscaler (HPA) to monitor the resource demand and automatically scale the number of pods.
