 Kubernetes has a "hub-and-spoke" API pattern. All API usage from nodes (or the pods they run) terminates at the apiserver. None of the other control plane components are designed to expose remote services. The apiserver is configured to listen for remote connections on a secure HTTPS port (typically 443) with one or more forms of client [authentication](/docs/reference/access-authn-authz/authentication/) enabled.
 One or more forms of [authorization](/docs/reference/access-authn-authz/authorization/) should be enabled, especially if [anonymous requests](/docs/reference/access-authn-authz/authentication/#anonymous-requests) or [service account tokens](/docs/reference/access-authn-authz/authentication/#service-account-tokens) are allowed.

 Pods that wish to connect to the apiserver can do so securely by leveraging a service account so that Kubernetes will automatically inject the public root certificate and a valid bearer token into the pod when it is instantiated.
 The `kubernetes` service (in `default` namespace) is configured with a virtual IP address that is redirected (via kube-proxy) to the HTTPS endpoint on the apiserver.
