The "node" command executes the following phases:

preflight       Run upgrade node pre-flight checks
control-plane   Upgrade the control plane instance deployed on this node, if any
kubelet-config  Upgrade the kubelet configuration for this node
kubeadm upgrade node [flags]

Options

--certificate-renewal     Default: true

--ignore-preflight-errors strings

A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.

--kubeconfig string     Default: "/etc/kubernetes/admin.conf"

The kubeconfig file to use when talking to the cluster. If the flag is not set, a set of standard locations can be searched for an existing kubeconfig file.

--patches string

Path to a directory that contains files named "target[suffix][+patchtype].extension". For example, "kube-apiserver0+merge.yaml" or just "etcd.json". "target" can be one of "kube-apiserver", "kube-controller-manager", "kube-scheduler", "etcd". "patchtype" can be one of "strategic", "merge" or "json" and they match the patch formats supported by kubectl. The default "patchtype" is "strategic". "extension" must be either "json" or "yaml". "suffix" is an optional string that can be used to determine which patches are applied first alpha-numerically.

--skip-phases strings
