Interesting, thanks! To be honest I haven't looked too much into Kubernetes so far because of the emphasis in cloud deployment, while my interest is in setting it up in bare metal.
There are plenty of people running Kubernetes on bare-metal. There are a number of resources out there for PXE-booting a Kubernetes cluster on bare-metal.
Yes, but the instructions that I've found to do so are based on installation via shell scripts, which I'm not comfortable with. I'd like to understand it well before running it even in a test setup.
