Can worker nodes' master be replace via kubeadm join alone?

ru flag

I have a single master setup with 3 worker nodes which is already being used. I need to convert the single-master to multi-master setup. I can only see the official doc where a "fresh" cluster is being setup with multi-master.

My plan is to kubeadm reset the current single-master node and then follow what's in the official doc. Keep the worker nodes running and then kubeadm join them to the new cluster when the multiple masters are ready, will this work?

Yes, it should be feasible. Do you encounter any problem while trying it ?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
