Your Kubernetes control-plane 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
Alternatively, if you are the root user, you can run:
  export KUBECONFIG=/etc/kubernetes/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:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/
You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:
  kubeadm join cluster-endpoint:6443 --token hums8f.vyx71prsg74ofce7 \
    --discovery-token-ca-cert-hash sha256:a394d059dd51d68bb007a532a037d0a477131480ae95f75840c461e85e2c6ae3 \
    --control-plane 
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join cluster-endpoint:6443 --token hums8f.vyx71prsg74ofce7 \
    --discovery-token-ca-cert-hash sha256:a394d059dd51d68bb007a532a037d0a477131480ae95f75840c461e85e2c6ae3

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
