brightbox: kubernetes bootstrap example

[tormath1]

This is an example of Kubernetes cluster bootstrapping on Brightbox using Systemd sysext Ignition configuration.

⚠️ This is really for demo purposes but it can serve as a foundation (for example don't pass the admin configuration through HTTP for workers to join)

• documentation
• get the kubeconfig as an output
• add outputs (IPs, etc.)

$ terraform apply
$ scp core@<IP from the output>:/home/core/.kube/config ~/.kube/config
$ kubectl get nodes

On every boot or only on first boot?

Thanks, done with condition - we should fix this in the documentation too.

This could be part of the README.md

Good idea. Added the note + a link to the Flatcar documentation.
