  Metal3 (Metal Kubed) is a CNCF incubating project that provides bare
  metal host provisioning for Kubernetes. It leverages Ironic for hardware
  management and integrates with the Cluster API to enable Kubernetes-native
  lifecycle management of bare metal infrastructure. Metal3 automates
  server discovery, inspection, provisioning, and deprovisioning using
  Kubernetes custom resources.

    description: >-
      Metal3 extends Kubernetes with the BareMetalHost custom resource for
      managing physical servers. The API supports hardware inventory discovery,
      firmware configuration, BIOS settings, RAID configuration, and OS
      provisioning. Combined with Cluster API, it enables declarative
      management of bare metal Kubernetes clusters.
