Example usage:

docker run -d --rm -p 443:6443 --name k8sfs chazapis/kubernetes-from-scratch:<tag>
docker cp k8sfs:/root/.kube/config kubeconfig
sed -i 's/server:.*/server: https:\/\/127.0.0.1:6443/' kubeconfig
export KUBECONFIG=$PWD/kubeconfig
kubectl version

Variable	Description	Default
K8SFS_HEADLESS_SERVICES	Start the webhook to make all services headless.	1
K8SFS_RANDOM_SCHEDULER	Start the random (pass-through) scheduler.	1
K8SFS_MOCK_KUBELET	Start the mock kubelet.	1
