Create the in-cluster configuration file for the first time from using flags.

Synopsis

Using this command, you can upload configuration to the ConfigMap in the cluster using the same flags you gave to ‘kubeadm init’. If you initialized your cluster using a v1.7.x or lower kubeadm client and set certain flags, you need to run this command with the same flags before upgrading to v1.8 using ‘kubeadm upgrade’.

The configuration is located in the “kube-system” namespace in the “kubeadm-config” ConfigMap.
