title: Recommended way to provide kubernetes metrics-server with its key pair?
body: <p>Are there any known issues with metrics-server and configmap? I’ve tried a zillion things to get it to work but unable to. If in my deployment manifest I simply replace "image: k8s.gcr.io/metrics-server-amd64:v0.3.3" with “image: docker.io/alpine” it can read configmap files. But metrics-server throws the following error:
  “no such file or directory” when attempting to reference a configmap file. Which tends to make me suspect the problem is in metrics-server rather than the k8s environment.</p>
  
  <p>My purpose is doing this is to make the server’s public and private keys (–tls-cert-file) available to the container. If a configmap is not the recommended way to provide the metrics-server its keys , please let me know what the recommended way is. (In tihs case I still would be curious why metrics-server cannot mount configmap volumes.)</p>
