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 can also be used for downgrading
cluster if necessary.

kubeadm upgrade guidance
Every upgrade process might be a bit different, so we've documented each minor upgrade process individually. For more version-specific upgrade guidance, see the following resources:
For older versions, please refer to older documentation sets on the Kubernetes website.
In Kubernetes v1.11.0 and later, you can use kubeadm upgrade diff to see the changes that would be
applied to static pod manifests.
To use kube-dns with upgrades in Kubernetes v1.13.0 and later please follow this guide.
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.
