kubeadm-config - Man Page

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

Eric Paris Jan 2015


kubeadm config [Options]


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 'config upload' command to create this ConfigMap. This is required so that 'kubeadm upgrade' can configure your upgraded cluster correctly.


--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

--azure-container-registry-config="" Path to the file containing Azure container registry configuration information.

--rootfs="" [EXPERIMENTAL] The path to the 'real' host root filesystem.

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