How to add more control plane modes without tearing down and reinstalling the cluster? about k3s-ansible HOT 3 CLOSED

Hi @rexdavid

You actually can. You just need to prepare the additional control plane node for ansible. And then add the node to hosts file, and re-run the site.yml ... then it will look like it is recreating the cluster when in fact it will just add the node to cluster, and the cluster will keep running...

I know this because I have added multiple clusters to an rancher install, and the new node just showed up in the correct cluster.

@timothystewart6 - you can close this issue, as it works like a charm. Thanks for the video, and the work on the ansible playbooks.

Hi!
This worked for me but only for adding worker nodes. I didn't manage to make it work with "control-plane,etcd,master" nodes
