Well-Known Certificate Authorities
----------------------------------

In these examples we've prearranged which root certificates to trust. But for regular HTTPS on the
Internet this set of trusted root certificates is usually provided by default by the host platform.
Such a set typically includes many root certificates from well-known certificate authorities like
Entrust and Verisign.

- Kubelet: if the `--client-ca-file` is updated while kubelet is running, the updated root certificates are now correctly used to advertise accepted authorities to TLS clients connecting to the kubelet endpoints. This behavior is guarded by the `ReloadKubeletClientCAFile` feature gate, which is enabled by default. ([#136762](https://github.com/kubernetes/kubernetes/pull/136762), [@HarshalNeelkamal](htt...
