Assuming it is something more than

--header "Authorization: Bearer $TOKEN"

(for example)

So it should be something like:

curl -k --fail -u "node:$TOKEN" --output /dev/null '<https://10.10.0.10:6443/livez?verbose>'

My response is still 401 (unauthorised). 🤔

If you just want to check the apiserver health, the best way is to use kubectl to make a raw request to the healthz endpoint

because this is being automated, I am checking from the worker nodes. kubectl has not yet been installed, etc. The idea is that the install scripts started on the workers would kick off via cloud-init, and loop waiting fpr the controller, then continue and install rke2 on the worker nodes, and join the controller.
