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

| --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", "kubeletconfiguration". "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. | |
