* Correct 'print default' command in kubeadm-config.md `kubeadm config print-default` command doesn't exist in v1.15.0. It's now `kubeadm config print init-defaults` and `kubeadm config print join-defaults`. * Remove the unnecessary v1.11.0 statement

|
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`.
|
|
|
|
You can use `kubeadm config print` 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.
|
|
|
|
In Kubernetes v1.13.0 and later to list/pull kube-dns images instead of the CoreDNS image
|
|
the `--config` method described [here](/docs/reference/setup-tools/kubeadm/kubeadm-init-phase/#cmd-phase-addon)
|
|
has to be used.
