Enhancement Description
HPA may include metrics from unrelated pods if they share the same labels as the target workload. This can cause incorrect scaling, such as staying at maxReplicas even when real usage is low. This proposal updates the HPA to only use pods directly managed by the target workload, avoiding incorrect metrics and improving scaling accuracy.
