What is an HPA in Kubernetes?
HPA stands for HorizontalPodAutoscaler. It is a concept and resource that allows clusters to scale out upon a certain condition being met. HPA can support a pod to scale based on certain amounts of CPU utilization. It natively supports granular CPU requests down to a single millicore. A .yaml file in Kubneretes has the key "kind"; if you want to read more about these files, see this posting. The value associated with this "kind" definition can be "HorizontalPodAutoscaler".
