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]

Options

-h, --help

help for config

--kubeconfig string     Default: "/etc/kubernetes/admin.conf"

The kubeconfig file to use when talking to the cluster. If the flag is not set, a set of standard locations can be searched for an existing kubeconfig file.

Options inherited from parent commands

--rootfs string

The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path.
