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.
