Introducing Metal³: Kubernetes Native Bare Metal Host Management
Talkat KubeCon + CloudNativeCon North America 2019 · on Wednesday, 2019-11-20· at 17:20· Ballroom Sec 20AB - San Diego Convention Center, Upper Level·
summary
Metal3 exposes a baremetalhost CRD to represent inventory, inspects hardware into status fields, and uses Ironic provisioning (bundled and self-hosted) to write whole-disk images and reboot nodes. A machine API actuator ties hosts to Machine/MachineSet so scaling a MachineSet finds a ready host, provisions it, and joins it as a Kubernetes/OpenShift node. Demos show inspection, image deploy, adding a worker to an OpenShift cluster, and creating a new cluster via Cluster API v1alpha2; failures surface as status errors.
