I just installed metrics-server on my kubernetes cluster running

But the pod do not boot and I have the following error 

0/4 nodes are available: 4 node(s) didn't match node selector.

Metrics server have below nodeSelector in the deployment yaml

  nodeSelector:
    kubernetes.io/os: linux
    kubernetes.io/arch: "amd64"

This error means that there is no node with label kubernetes.io/os: linux and kubernetes.io/arch: "amd64"

You can either remove the nodeSelector from the deployment yaml before deploying it or you can add those labels into your nodes.

kubectl label nodes <your-node-name> kubernetes.io/os=linux
kubectl label nodes <your-node-name> kubernetes.io/arch=amd64
