Completion
install bash-completion package

kubeadm completion bash|tee /etc/bash_completion.d/kubeadm
kubectl completion bash|tee /etc/bash_completion.d/kubectl

Bootstrapping the master node "Kubernetes control panel" :

kubeadm init --apiserver-advertise-address=192.168.205.10 --pod-network-cidr=10.244.0.0/16 --kubernetes-version=v1.6.2
## for calico default is 192.168.0.0/16 for flannel it is 10.244.0.0/16, not sure what needs to be done to vagrant for ips not clash
