Zero Configuration Pattern of Kubernetes on Bare Metal [A]
summary
Demonstrates immutable bootstrapping on bare metal using Digital Rebar and kubeadm to auto-provision nodes without SSH or external orchestration; two clusters (RAM fast-boot and full CentOS) are built in parallel, one node wins a leader election, runs kubeadm init, and other nodes retrieve the join token automatically — the demo works live and shows sub‑five‑minute turnups are practical. Explores zero-configuration node admission and TPM-signed tokens but concludes TPM adds complexity with marginal security gain.
