kubeadm reset phase

In v1.15.0, kubeadm introduces the kubeadm reset phase command with the aim of making kubeadm more modular. This modularity enables you to invoke atomic sub-steps of the reset process. Hence, you can let kubeadm do some parts and fill in yourself where you need customizations.

kubeadm reset phase is consistent with the kubeadm reset workflow, and behind the scene both use the same code.
