Metal³: Bare-Metal Management for Kubernetes

by Shriira Press

Metal³ (Metal Kubed) brings bare-metal host management to Kubernetes — managing physical servers as Kubernetes resources and provisioning Kubernetes clusters on bare metal, declaratively. This free book teaches it from the ground up: the bare-metal management problem and what Metal³ is, bare-metal provisioning concepts (BMCs, PXE, Ironic), Metal³'s architecture (the Bare Metal Operator over Ironic), the BareMetalHost resource, the provisioning lifecycle (inspection, provisioning, deprovisioning), hardware management (power, inspection, firmware, BMC protocols), Cluster API integration (provisioning Kubernetes clusters on bare metal), OS images and provisioning, scaling and operations (the host pool, on-prem/edge/telco), and using Metal³ in practice. Ten focused chapters with clear diagrams that demystify bare-metal management — turning manual physical-server provisioning into declarative, automated, Kubernetes-native infrastructure (bare metal like cloud), especially for on-prem, edge, and telco.
