Manage configuration for a kubeadm cluster persisted in a ConfigMap in the cluster
### Synopsis
There is a ConfigMap in the kube-system namespace called "kubeadm-config" that kubeadm uses to store internal configuration about the cluster. kubeadm CLI v1.8.0+ automatically creates this ConfigMap with the config used with 'kubeadm init', but if you initialized your cluster using kubeadm v1.7.x or lower, you must use the 'kubeadm init phase upload-config' command to create this ConfigMap. This is required so that 'kubeadm upgrade' can configure your upgraded cluster correctly.
``` kubeadm config [flags] ```
