Upload the kubeadm ClusterConfiguration to a ConfigMap

Synopsis

Upload the kubeadm ClusterConfiguration to a ConfigMap called kubeadm-config in the kube-system namespace. This enables correct configuration of system components and a seamless user experience when upgrading.

Alternatively, you can use kubeadm config.

kubeadm init phase upload-config kubeadm [flags]

Examples

  # upload the configuration of your cluster
  kubeadm init phase upload-config --config=myConfig.yaml

Options

--config string
	Path to a kubeadm configuration file.
--cri-socket string
	Path to the CRI socket to connect. If empty kubeadm will try to auto-detect this value; use this option only if you have more than one CRI installed or if you have non-standard CRI socket.
--dry-run
	Don't apply any changes; just output what would be done.
-h, --help
	help for kubeadm
--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.

Options inherited from parent commands

--rootfs string
	[EXPERIMENTAL] The path to the 'real' host root filesystem.
