- KuD that installs basic packages via Kubespray and packages that are not containerized. BPA can inherit this code.
- KuD that acts as private docker hub repository. BPA can inherit this code.
- KuD that builds the packages from the source code - this needs to be done outside of BPA and binary packages and container packages that result from these are expected to be part of USB bootable disk.
- KuD that brings containerized packages : This needs to be taken care as a script on top of infra-local-controller.
Infra-global-controller:
There could be multiple edges that need to be brought up. Administrator going to each location, using infra-local-controller to bring up application-K8S cluster in compute nodes of location is not scalable. "infra-global-controller" is expected to provide centralized software provisioning and configuration system. It provides one single-pane-of-glass for administrating the edge locations with respect to infrastructure. Administration involves
- First time bring up.
- Addition of new compute nodes in locations.
- Removal of compute nodes from locations
- Software patching
- Software upgrading
It is expected that infra-local-controller is brought up in each location. infra-local-controller kubeconfig is something that is expected to be made known to the infra-global-controller. Beyond that everything else is taken care by infra-global-controller.
