Metal3
One of the major challenges to cloud admin managing multiple clusters in different edge location is coordinate control plane of each cluster configuration remotely, managing patches and updates/upgrades across multiple machines. In ICN family stack, Bare Metal Operator from Metal3 project is used as bare metal provider. It is used as a machine actuator that uses Ironic to provide K8s API to manage the physical servers that also run K8s clusters on bare-metal host.
...
ICN project injects the user data in each server regarding network configuration, grub update to enable IOMMU, remote command execution using ssh and maintain a common secure mechanism for all provisioning the servers. Each local controller maintains IP address management for that edge location. For more information refer - Metal3 Bare Metal Operator in ICN stack

ICN uses the Cluster API to provision the infrastructure and bootstrap K8s clusters.
