Hi Ramesh, The short answer is that K8s packages VNFs are not (yet) a supported feature. For the Dublin release, only HEAT and TOSCA have support.
The longer answer is that we all know the platform needs to support K8s VNFs at some point. But with El Alto being a technical debt reduction release, I expect that Frankfurt is the earliest that this could be added. I believe one of the edge use cases may have some PoC/experimental code that may provide a starting point. The k8s VNF onboarding use case needs to be clearly defined and the impacts to the platform components identified and dev resources committed to implement the feature. This may be a good topic for the architecture committee and some of the DDF discussions this week. I assume helm charts would be needed for K8s to deploy a k8s VNF, but I do not know whether architecture would prefer this to be onboarded, or generated from something else (e.g. a TOSCA CSAR)? I would expect that even if deployed with k8s, that the VNF should support the same management interfaces ( VES, Netconf etc.) so that it can be managed by ONAP.

I am a newbie to ONAP and this is of great help. Few more clarifications please. Context and clarifications: In our case, we will be deploying VNF’s on Kubernetes based env. We are looking to do this using upcoming Dublin. Given this, * We were in need of understanding an example/demo VNF that meets ONAP requirements (with sample management API’s, with VNF Documentation packages as per documents, with VNF packaging contents that goes into CSAR, etc…). I think you pointed to vFW and vCPE. Can you point to its git source repo? * We need to package a VNF for K8S. A link to a sample CSAR would help. We are trying to understand * What are the contents of VNF CSAR looks like when it is packaged for K8S? * For instance, does VNF Provider have to provide helm charts instead of HEAT packages? Or TOSCA which will be converted internally to K8S API’s or helm charts by ONAP. * When a VNF is deployed on K8S, is the VNF is still expected to implement some Management API’s as per the ONAP requirements or should we just leave it to K8S API’s?
