We follow the validated Docker versions for upstream Kubernetes releases. The validated versions can be found under [External Dependencies](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.10.md#external-dependencies) in the Kubernetes release CHANGELOG.md.

The `kube-api-auth` microservice is deployed to provide the user authentication functionality for the [authorized cluster endpoint,](../../../../pages-for-subheaders/rancher-manager-architecture.md#4-authorized-cluster-endpoint) which is only available for [RKE clusters.](../../../../pages-for-subheaders/launch-kubernetes-with-rancher.md) When you access the user cluster using `kubectl`, the cluster's Kubernetes API server authenticates you by using the `kube-api-auth` service as a webhook.

During cluster provisioning, the file `/etc/kubernetes/kube-api-authn-webhook.yaml` is deployed and `kube-apiserver` is configured with `--authentication-token-webhook-config-file=/etc/kubernetes/kube-api-authn-webhook.yaml`. This configures the `kube-apiserver` to query `http://127.0.0.1:6440/v1/authenticate` to determine authentication for bearer tokens.

## Architecture for an Authorized Cluster Endpoint
If you are using an [authorized cluster endpoint,](../../pages-for-subheaders/rancher-manager-architecture.md#4-authorized-cluster-endpoint) we recommend creating an FQDN pointing to a load balancer which balances traffic across your nodes with the `controlplane` role.

If you are using private CA signed certificates on the load balancer, you have to supply the CA certificate, which will be included in the generated kubeconfig file to validate the certificate chain. See the documentation on [kubeconfig files](../../how-to-guides/advanced-user-guides/manage-clusters/access-clusters/use-kubectl-and-kubeconfig.md) and [API keys](../user-settings/api-keys.md#creating-an-api-key) for more information.
