Upload a configuration file to the in-cluster ConfigMap for kubeadm configuration.

### Synopsis



Using this command, you can upload configuration to the ConfigMap in the cluster using the same config file you gave to 'kubeadm init'.
If you initialized your cluster using a v1.7.x or lower kubeadm client and used the --config option, you need to run this command with the
same config file before upgrading to v1.8 using 'kubeadm upgrade'.

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