Image-Based Bare-Metal Provisioning With Metal3.io, Cluster API and…
summary
Production case study using image-based provisioning with Cluster API + Metal3.io and Ironic replaces PXE scripts with Kubernetes APIs and controllers. Provisioning time drops ~40% and cluster bring‑up falls from hours to under 30 minutes; clusters run ~150 bare‑metal nodes and thousands of clusters are managed in production. Controllers reconcile hardware, use a single immutable disk image plus checksum, perform automatic node replacement and firmware upgrades, and enable rolling or in‑place upgrades without manual runbooks.
