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/ Then you can join any number of worker nodes by running the following on each as root: kubeadm join 172.31.43.3:6443 --token 1jhsop.wiy4qe0tfqye80lp \ --discovery-token-ca-cert-hash sha256:63cf674da8de45ad1482fa70fb685734e9931819021f62f5ae7a078bba601bfc
