No Internet - No Problem? Air-Gapped Kubernetes on Bare Metal

on YouTube ↗45m

" summary

A fully automated, air-gapped Kubernetes on bare metal is built and bootstrapped from an air-gapped origin node on NixOS that serves ISOs, DHCP, NTP and image artifacts; Talos Linux runs the nodes with a static Talos Linux with embedded image cache used only until a local Zot registry is deployed. Core services install via Helm, platform and apps arrive as Zarf bundles + local Zot registry. Netboot quirks and mutable image cache limitations slow deployment; an MVP works but day‑2 operations remain immature.
