I have been trying out bootkube for a while now. It may be a beta, but I love the concept and how it works.

For those who have not heard about bootkube, its a tool which is used to bootstrap self-hosted clusters. Self-hosted essentially means running kubernetes as a objects on the kubernetes cluster ( I can hear people close their tabs ), its just kubernetes running on kubernetes. You can take a look at this video where Aaron Levy explains what self-hosted is and how you can benefit from it.
