I am trying to install a Kubernetes cluster on CentOS 7.3 servers. After some progress I got stuck on getting installing CNI plugin. To install plugin I need to pass a parameter which extracted from "kubectl version" command output. However command gets error when getting the required information, Server version:

[root@bigdev1 ~]# kubectl version
Client Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.0", GitCommit:"fff5156092b56e6bd60fff75aad4dc9de6b6ef37", GitTreeState:"clean", BuildDate:"2017-03-28T16:36:33Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}
Error from server (NotFound): the server could not find the requested resource

Actually I started using default documentation (https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/) with version kubeadm 1.7.3 (and Docker 17) but got stuck on a check:

[root@bigdev1 ~]# kubeadm init --pod-network-cidr=10.244.0.0/16

(waits here forever)

Then I decreased Docker version to 1.12.6 and kubernetes version to 1.6.0 After modifying kubeadm config. Also stopped passing cidr parameter to kubeadm init.

I will be glad if you can give any suggestions to get cleared of this issue or give the result of below command:

kubectl version | base64 | tr -d '\n'

Thanks in advance.
