I'm trying to get kube-apiserver prometheus metrics with kubectl command.

I can get it from kubectl proxy [which proxy the api in localhost:8001(by default)]. then go to http://localhost:8001/metrics

I want to get this metrics directly through kubectl command, without proxying.

My kubernetes version
