Where get validators for validate kube-proxy and kubelet config?

Hi.

I’m trying to learn how to install kubernetes and need help. I launch kubeadm v1.17.0.

kubeadm init phase preflight

writes immediately in the first two lines:

Cannot validate kube-proxy config - no validator is available
Cannot validate kubelet config - no validator is available

Tell me where to get these validators?
