---------------------------------------------------
Your Kubernetes master has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
You can now join any number of machines by running the following on each node
as root:
kubeadm join 10.121.222.17:6443 --token wkj0bo.pzibll6rd9gyi5z8 --discovery-token-ca-cert-hash sha256:51985223a369a1f8c226f3ccdcf97f4ad5ff201a7c8c708e1636eea0739c0f05
