add hetzner template #106

Open rgarcia opened 4 months ago

rgarcia commented 4 months ago

Addresses #76

Basically followed the directions of @neoaggelos in that issue and got a hetzner template up and running

clusterctl generate cluster hetzner-microk8s-test --from ./templates/cluster-template-hetzner.yaml | kubectl apply -f -

About 3 minutes later

clusterctl describe cluster hetzner-microk8s-test                 
NAME                                                                       READY  SEVERITY  REASON  SINCE  MESSAGE

Curious if 3 minutes is typical. Tailing journalctl -f --system on the control plane node during startup and it seemed to be generating a lot of logs that I've yet to inspect.

only thing that stood out to me in the logs:

May 03 00:34:59 hetzner-microk8s-test-control-plane-2cttj cloud-init[692]: 2024-05-03 00:34:59,509 - schema.py[WARNING]: Invalid cloud-config provided: Please run 'sudo cloud-init schema --system' to see the schema errors.

Running sudo cloud-init schema --system shows:

Other than that I noticed two occurences of snap restart microk8s.daemon-kubelite within 15 seconds of each other which seemed odd.
