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. | |
