### The kubelet Kubernetes Configuration File
When generating kubeconfig files for Kubelets the client certificate matching the Kubelet's node name must be used. This will ensure Kubelets are properly authorized by the Kubernetes [Node Authorizer](https://kubernetes.io/docs/admin/authorization/node/).
Generate a kubeconfig file for the first worker node:
```
for instance in worker-1; do
kubectl config set-cluster kubernetes-the-hard-way \
--certificate-authority=ca.crt \
--embed-certs=true \
--server=https://${LOADBALANCER_ADDRESS}:6443 \
--kubeconfig=${instance}.kubeconfig
kubectl config set-credentials system:node:${instance} \
--client-certificate=${instance}.crt \
--client-key=${instance}.key \
--embed-certs=true \
--kubeconfig=${instance}.kubeconfig
kubectl config set-context default \
--cluster=kubernetes-the-hard-way \
--user=system:node:${instance} \
--kubeconfig=${instance}.kubeconfig
kubectl config use-context default --kubeconfig=${instance}.kubeconfig
