The **TLS certificates** are **associated with a domain name**, not with an IP address.

So, to renew the certificates, the renewal program needs to **prove** to the authority (Let's Encrypt) that it indeed **"owns" and controls that domain**.

- `kubeadm alpha certs renew --csr-only` now reads the current certificates as the authoritative source for certificates attributes (same as kubeadm alpha certs renew). ([#77780](https://github.com/kubernetes/kubernetes/pull/77780), [@fabriziopandini](https://github.com/fabriziopandini))

- Kubelet now exports a `server_expiration_renew_failure` and `client_expiration_renew_failure` metric counter if the certificate rotations cannot be performed. ([#84614](https://github.com/kubernetes/kubernetes/pull/84614), [@rphillips](https://github.com/rphillips)) [SIG API Machinery, Auth, CLI, Cloud Provider,...

* kubeadm allows the kubelets in the cluster to automatically renew their client certificates ([#53252](https://github.com/kubernetes/kubernetes/pull/53252), [@kad](https://github.com/kad))

on a node host or move it to a safe location. `kubadm certs renew` will renew the certificate in `super-admin.conf` to one year if the file exists; if it does not exist a "MISSING" note will be printed. `kubeadm upgrade apply` for this release will migrate this particular node to the two file setup. Subsequent kubeadm releases will continue to optionally renew the certificate in `super-admin.conf` if the file exists on disk and if renew on upgrade is not disabled. `kubeadm join --control-plane` will...

* Fix error in `kubeadm join --discovery-file` when using discovery files with embedded credentials ([#80675](https://github.com/kubernetes/kubernetes/pull/80675), [@fabriziopandini](https://github.com/fabriziopandini))
* make node lease renew interval more heuristic based on node-status-update-frequency in kubelet ([#80173](https://github.com/kubernetes/kubernetes/pull/80173), [@gaorong](https://github.com/gaorong))

- Added option to create CSRs instead of certificates for kubeadm init phase certs and kubeadm alpha certs renew ([#70809](https://github.com/kubernetes/kubernetes/pull/70809), [@liztio](https://github.com/liztio))
