i just wondered if there's any documentation about how to setup a hybrid k8s cluster (which resides in parts on local on-premises components but can scale into the cloud, either with nodes or even a master). I'm aware of the federation feature, but this only covers two individual clusters, not a single one which scales dynamically into the cloud. Is there any documentation about such a scenario? At least some do's and dont's?

I've got some basic ideas on how build a cluster like this, but perhaps there's some info on how to avoid some common pitfalls.

I already searched quite a lot of documentation, but you only get results for the federation feature or 'hybrid' as in mixed linux/windows clusters...
