SDC 28/08/2017 weekly meeting report

Agenda:

The agenda will be:

1.  

   1. Discussion of the CSAR structure supported for R1

   2. Discussion on the sequence design in SDC

discussion points:

1. SDC supported input CSAR structure which is supported for R1.

   1. 3 Directories: /TOSCA-Metadata, /Artifacts, /Definitions

   2. SDC development team to check if the import CSAR structure can be the same as the output CSAR structure (nested directories inside /Artifacts)

   3. SDC is not supporting images in R1

   4. SDC is doing basic package validation and would fail incorrect package structure/content

   5. VNFSDK team asks about SDC TOSCA validation code

2. SDC presented the number of options for VNF sequencing. 

   1. Using the relationships between the nodes - The following example (https://www.semanticscholar.org/paper/Combining-Declarative-and-Imperative-Cloud-Applica-Breitenb%C3%BCcher-Binz/61332d7f1763d56e298ce59855aed921a61d1f87)
      Shows how the relationships in the model translated to the instantiation sequencing:
      
      

   2. Using the workflow - suggesting to check with SO and VF-C how this is done today

3. Aug-29 Modelling call will have a slot to discuss the leftovers about CSAR package format

4. SDC suggested having a 3-hours call with VF-C team to manually craft one of VoLTE VNFs and the discuss SDC output 

5. VF-C needs to discuss with VoLTE use case team the E2E flow how the design-time output gets to VF-C. Possible options (additional options might exist):
   
   

   1. Option 1: 

      1. VF-C implements DMaaP API to register on service and resource notification

      2. VF-C implements SDC catalog API to get service and VNFs

   2. Option 2:

      1. VF-C implements only SDC catalog API and based on SO call gets the service/VNFs from SDC

Action items (to be completed by Tuesday Aug-29):

1. Can the SDC support nested artifacts in imported CSAR?  (owner Tal H.)

2. can the CSAR structure be aligned according to the request to have the service template yaml and mf in the root level (owner Meopeng)

3. Provide VNFSDK team with information and code location about the current SDC CSAR validations (owner Tal H.)

4. VF-C team to provide the list of artifacts that would be included in the onboarded VNF and used by VF-C (owner Meoperg)

5. SDC team to make sure WiKi page is updated with the latest CSAR structure documentation (owner Michael L.)

6. SDC development team to response VF-C questions about TOSCA parser (owner Michael L.)

00:38:55 maopeng: TOSCA-Meta-Version: 1.0 CSAR-Version: 1.0 Created-By: Winery 0.1.37-SNAPSHOT Entry-Definitions: Definitions/openons__vIMS_NS.yaml
00:40:16 maopeng: TOSCA-Meta-File-Version: 1.0 CSAR-Version: 1.1 Created-By: Carlos Santana Entry-Definitions: Definitions/service-33d1f589Dfbc492e8e9b-template.yml
00:45:21 DENG Hui: will VFC get same package format from SDC?
00:46:05 DENG Hui: one change in artificats, two directory: deployment
00:49:33 Nagesha (Nokia): what does helloworld.yml contain ?
00:52:56 DENG Hui: will CSAR package be used for heat vnf as well?
00:54:57 maopeng: In R1, can the VNF package incloude other directiories besides the three mentioned?
00:55:00 David Shadmi: There are some discussion about using it for vCPE. however it would not include HEAT.
00:55:25 David Shadmi: additional directories would be discarded.
00:56:14 David Shadmi: the comment about "additional directories would be discarded" is a response to @maopeng
01:00:15 maopeng: understand, but it is too limited for the VNF vendors. If it can support additional dirctories, it will be more helpful.
01:03:41 DENG Hui: maopeng, could it create other folder under artifact, not in the root directory?
01:04:31 maopeng: it has said it does not support the nesting directories in the artifacts
01:05:18 halfont: David said that we will check it tomaroow and give an answer about it
01:06:10 Nagesha (Nokia): Is this CSAR format for VNF package and also for service package (which user creates service using SDC gui) ?
01:15:08 DENG Hui: mainservice template.mf is duplicate of tosca.meta for SDC
01:16:01 Bharath Thiruveedula-Verizon: can we quickly discuss about the VNF sequencing after this topic, we raised about VNF sequencing in mailing list https://lists.onap.org/pipermail/onap-discuss/2017-August/003803.htm
01:17:41 Nagesha (Nokia): is "MainServiceTemplate" hardcoded name or it can be anything abc.yaml ?
01:17:52 DENG Hui: copy both files from definitions to root
01:18:02 DENG Hui: can u do it ?
01:20:17 DENG Hui: tosca.meta will still configure root direcotry?
01:20:24 maopeng: Entry-Definitions: ./MainserviceTemplate.yaml
01:21:40 DENG Hui: clear
01:22:15 DENG Hui: just copy, don't change content
01:23:54 Victor Gao: does the mainservicetemplate is hardcode?
01:24:13 Victor Gao: the name of ya m l
01:27:52 Nagesha (Nokia): in format the services are distributed ?
