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 …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.
