Each kubeconfig requires a Kubernetes API Server to connect to. To support high availability the IP address assigned to the external load balancer fronting the Kubernetes API Servers will be used.
Retrieve the `kubernetes-the-hard-way` static IP address:
```
KUBERNETES_PUBLIC_ADDRESS=$(gcloud compute addresses describe kubernetes-the-hard-way \
--region $(gcloud config get-value compute/region) \
--format 'value(address)')
```
Generate a kubeconfig file suitable for authenticating as the `admin` user:
```
kubectl config set-cluster kubernetes-the-hard-way \
--certificate-authority=ca.pem \
--embed-certs=true \
--server=https://${KUBERNETES_PUBLIC_ADDRESS}:6443
```
{
KUBERNETES_PUBLIC_ADDRESS=$(gcloud compute addresses describe kubernetes-the-hard-way \
--region $(gcloud config get-value compute/region) \
--format 'value(address)')
```
kubectl config set-credentials admin \
--client-certificate=admin.pem \
--client-key=admin-key.pem
```
kubectl config set-cluster kubernetes-the-hard-way \
--certificate-authority=ca.pem \
--embed-certs=true \
--server=https://${KUBERNETES_PUBLIC_ADDRESS}:6443
```
kubectl config set-context kubernetes-the-hard-way \
--cluster=kubernetes-the-hard-way \
--user=admin
```
kubectl config set-credentials admin \
--client-certificate=admin.pem \
--client-key=admin-key.pem

kubectl config set-context kubernetes-the-hard-way \

kubectl config use-context kubernetes-the-hard-way
