HPA (Horizontal Pod Autoscaler)

The Horizontal Pod Autoscaler is the Kubernetes feature that adds or removes copies (replicas) of a workload based on a metric such as CPU use, within set minimum and maximum counts. When ZopNight stops a namespace it removes the HPA and restores it on start. Why it matters: Its minimum sets a floor on spend, and a workload stuck at its maximum is a sign of too little capacity.
