metal-stack - kubernetes on bare metal
summary
metal-stack is an open source bare‑metal MaaS: a REST API plus a cloud controller manager integrated with Gardener to create Kubernetes clusters. It uses metal-hammer for PXE discovery, one minute provisioning for images/ignition, layer‑3 networking with BGP + FRR and metal‑lb for Service IPs, and currently a local CSI-like storage provisioner. Running in three DCs (~100 servers each) in early production, it works but is alpha (API changes, storage still evolving).
