The lab is a Kubernetes testbed: try cluster layouts here before they go to production. After a short manual bootstrap, Flux keeps the cluster in sync with Git — the usual GitOps loop of declared state in version control and controllers that apply diffs.

Nodes run Talos Linux on Turing Pi RK1 boards. Images come from the Talos Image Factory (metal-arm64, sbc-rockchip / turingrk1). Talos keeps the node OS small and API-driven: you do not SSH in to patch packages. That pushes complexity into Kubernetes manifests, which fits a GitOps workflow.

Everything after the first bootstrap lives in one monorepo: cluster overlays, shared operators, Helm charts, and application kustomizations. Talos machine config (talconfig) is versioned there too, but applied with talosctl, not Flux. Drawing that line clearly avoids pretending the entire world is reconciled from Git when the hypervisor and disk layout are still operator steps.
