For learning purposes! 👨🏫
Also, there seems to be some demand for scraping metrics-server using Prometheus.
It works by directly querying the metrics.k8s.io/v1beta1 API whenever the /metrics endpoint is scraped.
In your local workstation by running
$ docker run \
-p 9100:9100 \
-v $HOME/.kube/config:/kubeconfig.yaml:ro \
quay.io/bmcstdio/kube-metrics-prom:v0.1.0 \
--kubeconfig /kubeconfig.yaml
or inside a Kubernetes cluster by running
$ kubectl create -f ./examples/kube-metrics-prom.yml
