cd $HOME/.kube
echo "get /etc/rancher/k3s/k3s.yaml ${CLUSTER_NAME}" | sftp -s "sudo /usr/lib/openssh/sftp-server" ${MASTER_NODE_USERNAME}@${MASTER_NODE_IP}
server="https://${MASTER_NODE_IP}:6443" yq -i ".clusters[0].cluster.server = env(server)" ${CLUSTER_NAME}
export KUBECONFIG=$HOME/.kube/${CLUSTER_NAME}
kubectl get nodes
