Upload the kubeadm ClusterConfiguration to a ConfigMap
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]
# upload the configuration of your cluster kubeadm init phase upload-config --config=myConfig.yaml
Path to a kubeadm configuration file.
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.
Don't apply any changes; just output what would be done.
