Show release candidate versions of Kubernetes as an upgrade alternative and allow upgrading to a release candidate versions of Kubernetes.

Path to a kubeadm configuration file.

Do not change any state, just output what actions would be performed.

Force upgrading although some requirements might not be met. This also implies non-interactive mode.

help for preflight

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

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.

Perform the upgrade and do not prompt for confirmation (non-interactive mode).

The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path.

Perform the renewal of certificates used by component changed during upgrades.

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", "corednsdeployment". "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.
