We have seen a number of questions around the usage of "config print". Clarify the usage of this command. Add a note that the output should not be taken literally. Link to the "customizing components" page instead of the "kubelet integration" page. The former already links to the later. Remove note about kube-dns which hasn't been supported for a while.

kubeadm config | concept | 50 |
During kubeadm init, kubeadm uploads the ClusterConfiguration object to your cluster
in a ConfigMap called kubeadm-config in the kube-system namespace. This configuration is then read during
kubeadm join, kubeadm reset and kubeadm upgrade.
You can use kubeadm config print to print the default static configuration that kubeadm
uses for kubeadm init and kubeadm join.
{{< note >}} The output of the command is meant to serve as an example. You must manually edit the output of this command to adapt to your setup. Remove the fields that you are not certain about and kubeadm will try to default them on runtime by examining the host. {{< /note >}}
For more information on init and join navigate to
Using kubeadm init with a configuration file
or Using kubeadm join with a configuration file.
For more information on using the kubeadm configuration API navigate to Customizing components with the kubeadm API.
You can use kubeadm config migrate to convert your old configuration files that contain a deprecated
API version to a newer, supported API version.
kubeadm config images list and kubeadm config images pull can be used to list and pull the images
that kubeadm requires.
