Beginning with v1.8.0, kubeadm uploads the configuration of your cluster to a ConfigMap called
|
|
`kubeadm-config` in the `kube-system` namespace, and later reads the ConfigMap when upgrading.
|
|
This enables correct configuration of system components, and provides a seamless user experience.
|
|
|
|
You can execute `kubeadm config view` to view the ConfigMap. If you initialized your cluster using
|
|
kubeadm v1.7.x or lower, you must use `kubeadm config upload` to create the ConfigMap before you
|
|
may use `kubeadm upgrade`.
|
|
|
|
In Kubernetes v1.11.0, some new commands were added. You can use `kubeadm config print-default`
|
|
to print the default configuration and `kubeadm config migrate` to convert your old configuration
|
|
files to a newer version. `kubeadm config images list` and `kubeadm config images pull` can be used
|
|
to list and pull the images that kubeadm requires.
