How to scale down a Talos cluster
To remove nodes from a Talos Linux cluster:
talosctl -n <IP.of.node.to.remove> reset
kubectl delete node <nodename>
talosctl reset will cordon and drain the node, leaving
etcd if required, and then erase its disks and power down the system.
This command will also remove the node from registration with the discovery service, so it will no longer show up in
talosctl get members.
It is still necessary to remove the node from Kubernetes, as noted above.
