All the green items are existing open source projects. If they require any enhancements, it is best done in the upstream community.

...

• When new compute node is added, once administrator adds new compute node in the site list, it shall take care of installing the packages.
• If a new binary package version is uploaded, it shall take care of figuring out the compute nodes that require this new version and update that compute node with the new version.

BPA is expected to store any secret information in SMS.

Implementation suggestions:

...

• 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.
• SMS (Secret Management Service) can be used ASIS.  Integration with SMS can be for Akraino-R2 and not for interim release

Infra-global-controller: 

...

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. infra-global-controller communicates with various infra-local-controllers to do the job of software installation and provisioning.

Design Details

infra-local-controller (Kuralamudhan Ramakrishnan, please fill up this section and subsections of this - Define CRD, give example CRs and then fill up sequence diagrams, directory structure of source code for various modules etc...)

Global ZTP:

Global ZTP system is used for Infrastructure provisioning and configuration in ICN family. It is subdivided into 3 deployments Cluster-API, KuD and ONAP on K8s.
