During the 4 August 2017 virtual meeting, the VNF SDK Models sub-project reached consensus on the recommendations with respect to the VNF Package Model and the VNF Descriptor Model for ONAP Release 1 (Amsterdam): specifically the VNF package model should endorse the ETSI NFV SOL004 v2.3.1 based CSAR Option 2 with focus on Manifest file.
Decision revisited and amended on 25 August 2017, as part of the VNF SDK Project Meeting based on time constraints driven by VF-C and VNF-vendors supplying the VNF's for ONAP R1.
Discussed revised references during 1 September 2017 call
TOSCA version spec: TOSCA Simple Profile in YAML Version 1.1 TOSCA CSAR-Version: 1.1 With option 1 (a TOSCA-Metadata directory ): Manifest file: CSAR package support with and without manifest file
VNF Package Model Proposal for Release 1
TOSCA Simple Profile in YAML Version 1.1 (updated 1 SEP 2017)
TOSCA CSAR-Version: 1.1 With option 1 (a TOSCA-Metadata directory ): Manifest file: CSAR package may optionally support with manifest file (for integrity check) (updated 1 SEP 2017)
CSAR format compatible with what is used by the VF-C project (25 AUG 2017)CSAR format for R1 is to be based on TOSCA 1.1 CSAR format with Metadata Files (25 AUG 2017)ETSI NFV SOL004 v2.3.1 focus on Manifest(Optionally consider VNF Package model draft requirements in VNFRQTS-28 for beyond Release 1)Proposal for ONAP CSAR R1 are uploaded in the modeling contribution files directory https://wiki.onap.org/download/attachments/8226078/ONAP_CSAR.pptx?api=v2
With a focus on the VNF Package Structure (Option 2): TOSCA YAML CSAR without Metadata FileNote: Team will continue to evolve the models beyond this recommendation.
VNF Descriptor Model Proposal for Release 1
- VNF Descriptor be based on OASIS TOSCA NFV YAML Profile v1.0 CSD04
- For release 1 use of OASIS TOSCA NFV YAML Profile WD04-rev6 may be acceptable for the current implementations to help aid with backward compatibility
- It is desirable to include Approved IFA011 Change Requests - VDU restructuring (i.e. key-value pair arrays)
- (Optionally consider VNF Descriptor model draft requirements in VNFRQTS-28 for beyond Release 1)
Note: Team will continue to evolve the models beyond this recommendation.
