I'm looking into this. How and how difficult is it to get K8 onto baremetal? Could you point me towards tooling and best practices for running K8 on baremetal?
The short answer is: It's pretty ugly. I don't know the details, but we PXE-boot and install CoreOS, then run kubelet using rkt (using a systemd service). The other k8s components (etcd, apiserver, controller manager etc.) are managed by the kubelet using static manifests. Persistent volumes are backed by a separate storage appliance via NFS.
Our team built this entire process ~2 years ago, when we started using k8s. We would probably use some off-the-shelf parts today, but practically nothing existed back then.
