before start, i'm running kubernetes on mac.
- minikube: 1.17.0
- metrics-server: 1.8+
- vpa: vpa-release-0.8
my issue is vpa doesn't scale up my pod just keep recreating pods. i followed gke vpa example. i set resource requests of deployment cpu: 100m, memory: 50mi. and deploy vpa. it gave me recommendation. updatemode is Auto as well. but it keep recreating pod, doesn't change resource requests when i checked the pod what recreated by kubectl describe pod podname.

i tried with kind as well. but it recreate pods with new resource request, but never run keep pending because the node's resource is not enough. and i think the reason why vpa doesn't work properly is minikube or me didn't make multiple node. you think is that relative?
