[Roadmap] Support node specific configuration #2367
Description
Kubeadm as of today does not provide a first-class support node-specific configuration.
There are ways to achieve this, like using patches, or for kubelet only, by providing node-specific extrargs, but in the end, the UX is not ideal and we are not covering all the use cases.
As a consequence, I'm proposing to include in the discussions for the next kubeadm roadmap also a definition of proper support for node-specific configurations in the kubeadm API, possibly in line with the outcomes of the ongoing discussion in kubernetes/enhancements#1439.
This should cover both the core components managed by kubeadm (API server, controller-manager, scheduler, etcd, kubelet) but also addon when this makes sense.
