# kubeadm-config(1)

Manage configuration for a kubeadm cluster persisted in a ConfigMap in the cluster

Eric Paris Jan 2015

## NAME

kubeadm config - Manage configuration for a kubeadm cluster persisted in a ConfigMap in the cluster

## SYNOPSIS

**kubeadm config** \[OPTIONS\]

## DESCRIPTION

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.

## OPTIONS

**--kubeconfig**="/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**=""\
 	The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path.

**--version**=false\
 	\--version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version
