** NOTICE**
# In case you have installed Flannel, you need to start kubeadm like this:
kubeadm init --pod-network-cidr=10.244.0.0/16

# instead of Weavenet, then you need more CNI binary rather than just loopback.
# These are: (bridge, flannel, host-local, loopback, portmap).
# All of these are included in the compressed *.tgz archive.


# Check the coredns is now running


# Deploy Dashboard
kubectl -n kube-system edit service kubernetes-dashboard
Change type: ClusterIP to type: NodePort and save file. If it's already changed go to next step.
Next we need to check port on which Dashboard was exposed. (See TCP Ports)
