Hello!
We are running Hetzner-k3s version 2.0.8 with the following worker pool config:
The nodes are created in Hetzner after autoscaling is initiated by stressing the cluster but they are not joining the cluster after that. We can ssh into the machines but they don't have for example ssh keys set or anything related to k3s installed. For static nodes the ssh keys are set correctly.
We think this has something to do with the previous cloud init wait problem in issue https://github.com/vitobotta/hetzner-k3s/issues/379
If we read the code correctly the cloud_init_wait.sh script is not called when creating a autoscaled node?
We are running a private network only cluster. Regarding to this PR https://github.com/vitobotta/hetzner-k3s/pull/458 our cloud init takes several minutes with both static and autoscaled nodes.
