GKE에서 scale‑down‑utilization‑threshold를 정의할 수 있나요? (Is definining scale‑down‑utilization‑threshold on GKE possible?)

GKE에서 scale‑down‑utilization‑threshold를 정의할 수 있습니까? 실제로 가능한 경우 이것을 정의할 위치를 알 수 없습니다.

I'm not sure if you mean scale down an HPA or scale down a VPA or scale down cluster nodes based on the cluster autoscaler, or scale down GCP instance groups or an AWS ASGs.

• A Kubernetes HPA supports it based on a metric (typically CPU utilization). It will scale down to a minimum number of replicas defined in the HPA Kubernetes resource.

• A Kubernetes VPA supports it based on requests/limits (CPU, Memory). Keep in mind that it's not supported if used together with an HPA that is also using CPU and memory as scale metrics.

• The Kubernetes cluster autoscaler also supports downscaling based on the ‑‑scale‑down‑utilization‑threshold and ‑‑scan‑interval options. It's not recommended to use this together with a GCP instance group or an AWS ASG.

• GCP Instance groups or AWS ASGs scale down is supported on the nodes provided that you are not using the cluster autoscaler and using CPU or other metrics specific to the cloud provider VM instances.

Hope it helps
