kubeadm upgrade [page]deterministic

`kubeadm upgrade` is a user-friendly command that wraps complex upgrading logic behind one command, with support for both planning an upgrade and actually performing it.

## kubeadm upgrade guidance

The steps for performing an upgrade using kubeadm are outlined in [this document](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/). For older versions of kubeadm, please refer to older documentation sets of the Kubernetes website.

You can use `kubeadm upgrade diff` to see the changes that would be applied to static pod manifests.

In Kubernetes v1.15.0 and later, `kubeadm upgrade apply` and `kubeadm upgrade node` will also automatically renew the kubeadm managed certificates on this node, including those stored in kubeconfig files. To opt-out, it is possible to pass the flag `--certificate-renewal=false`. For more details about certificate renewal see the [certificate management documentation](/docs/tasks/administer-cluster/kubeadm/kubeadm-certs).

The commands `kubeadm upgrade apply` and `kubeadm upgrade plan` have a legacy `--config` flag which makes it possible to reconfigure the cluster, while performing planning or upgrade of that particular control-plane node. Please be aware that the upgrade workflow was not designed for this scenario and there are reports of unexpected results.
