Kube-up actually uses Salt for some of the setup. But it's a big mess, since it needs to support a lot of platforms, Linuxes and cloud providers.

I don't know what the future of Kubernetes setup is, exactly, but right now it's quite safe to settle on Salt, Puppet, Ansible or Terraform. I haven't used Terraform, so I don't know how suitable it is to OS-level setup (things that the aforementioned tools are good at), as opposed to orchestration.

When you click the GKE(hosted Kubernetes) button on Google Cloud Platform, it's those very Salt configs that set up your nodes (and once upon a time they setup your control plane too).

Basically what's arguably the best publicly available Kubernetes setup in the world is hiding in that Salt codebase, and EVERY would-be Kubernetes admin should look at it before venturing on their own.

I used it as inspiration for my setup. But you also need a bunch of other stuff, like the CA setup and Kubelet cert generation, which are buried in the whole kube-up structure.

Yeah, agreed. CoreOS + cloud-init could remove necessity to do OS-level setup.

There's always something to do at the OS-level, which is why cloud-init configurations tend to spiral out of control with in-line scripts, configs, and binary downloads.

There's no getting away from configuration management and software installation at SOME level of your stack, and setting up a substrate for Kubernetes is no exception.
