This will help you provision Kubernetes v1.6.2 master on this machine. 

The following mirrors will be used due to inaccessibility of official resources.
https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
registry.aliyuncs.com/archon/hyperkube-amd64:v1.6.2
registry.aliyuncs.com/archon/etcd:3.0.17

You will be prompted to input custom docker hub mirror and preferred network layer.

Are you sure to continue? (y/N) y

Your Kubernetes master has initialized successfully!

To start using your cluster, you need to run (as a regular user):

  sudo cp /etc/kubernetes/admin.conf $HOME/
  sudo chown $(id -u):$(id -g) $HOME/admin.conf
  export KUBECONFIG=$HOME/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  http://kubernetes.io/docs/admin/addons/

You can now join any number of machines by running the following on each node
as root:

  kubeadm join --token an0m5l.c01thva8k6w5wxlk 192.168.0.192:6443

Available network layer:
1) Flannel
2) Calico (mem>1.5G && requires a docker mirror)
3) Skip
