### The kube-proxy Kubernetes Configuration File
### The Kubernetes Service Configuration Files
Generate a kubeconfig file for the `kube-proxy` service:
Generate a `.kubeconfig` file for the `kube-proxy`, `kube-controller-manager`, and `kube-scheduler` services:
```bash
{
for service in proxy controller-manager scheduler; do
kubectl config set-cluster kubernetes-the-hard-way \
--certificate-authority=ca.crt \
--embed-certs=true \
--server=https://server.kubernetes.local:6443 \
--kubeconfig=kube-proxy.kubeconfig
--kubeconfig=kube-${service}.kubeconfig
kubectl config set-credentials system:kube-proxy \
--client-certificate=kube-proxy.crt \
--client-key=kube-proxy.key \
kubectl config set-credentials system:kube-${service} \
--client-certificate=kube-${service}.crt \
--client-key=kube-${service}.key \
--embed-certs=true \
--kubeconfig=kube-proxy.kubeconfig
--kubeconfig=kube-${service}.kubeconfig
kubectl config set-context default \
--cluster=kubernetes-the-hard-way \
--user=system:kube-proxy \
--kubeconfig=kube-proxy.kubeconfig
--user=system:kube-${service} \
--kubeconfig=kube-${service}.kubeconfig
kubectl config use-context default \
--kubeconfig=kube-proxy.kubeconfig
}
--kubeconfig=kube-${service}.kubeconfig
done
```
Results:
```text
kube-proxy.kubeconfig
```
### The kube-controller-manager Kubernetes Configuration File
Generate a kubeconfig file for the `kube-controller-manager` service:
```bash
{
kubectl config set-cluster kubernetes-the-hard-way \
--certificate-authority=ca.crt \
--embed-certs=true \
--server=https://server.kubernetes.local:6443 \
--kubeconfig=kube-controller-manager.kubeconfig
kubectl config set-credentials system:kube-controller-manager \
--client-certificate=kube-controller-manager.crt \
--client-key=kube-controller-manager.key \
--embed-certs=true \
--kubeconfig=kube-controller-manager.kubeconfig
kubectl config set-context default \
--cluster=kubernetes-the-hard-way \
--user=system:kube-controller-manager \
--kubeconfig=kube-controller-manager.kubeconfig
kubectl config use-context default \
--kubeconfig=kube-controller-manager.kubeconfig
}
```
Results:
```text
kube-controller-manager.kubeconfig
```
### The kube-scheduler Kubernetes Configuration File
Generate a kubeconfig file for the `kube-scheduler` service:
```bash
{
kubectl config set-cluster kubernetes-the-hard-way \
--certificate-authority=ca.crt \
--embed-certs=true \
--server=https://server.kubernetes.local:6443 \
--kubeconfig=kube-scheduler.kubeconfig
kubectl config set-credentials system:kube-scheduler \
--client-certificate=kube-scheduler.crt \
--client-key=kube-scheduler.key \
--embed-certs=true \
--kubeconfig=kube-scheduler.kubeconfig
kubectl config set-context default \
--cluster=kubernetes-the-hard-way \
--user=system:kube-scheduler \
--kubeconfig=kube-scheduler.kubeconfig
kubectl config use-context default \
--kubeconfig=kube-scheduler.kubeconfig
}
```
Results:
```text
kube-scheduler.kubeconfig
```
