Jakarata - Helm migration 

@Vijay Kumar 

Discuss DCAE transformation planned items for J release - DCAEGEN2-2773

Priorities

• Switch components to latest SDK version

• OOM charts updates to disable Cloudify/handlers (CBS may be exception depending on above item)

  • Iteration 1 (once OOM branching is done)- Disable all cloudify/handlers under dcaegen2 

  • Iteration 2 (M3/Jakarta)- Move VESOpenAPI and CBS? to dcaegen2-services 

• Integration testsuite migration

• Helm flow support through MOD 

• DMaap Provisioning optimization

  • Pub/sub credential handling alignment - OKAY to proceed 

  • Topic/Feed cleanup on undeploy -

    • Topic cleanup to be split into separate Jira and assessed later ; Feed cleanup OKAY to proceed. (Impacted by AAF removal, Strimzi Operator introduction)

• Review - DCAEGEN2-2774   DCAE MS SVC template enhancement - Deferred to K release

  • Any new usecase/MS demanding these features for J release (otherwise Jira will be moved to backlog)

• CBS removal for DFC has dependency on DCAEGEN2-2935

Closed:

• Disable DCAE platform in deployment - https://gerrit.onap.org/r/c/oom/+/125731 

• DCAE Mod helm flow support - https://gerrit.onap.org/r/c/oom/+/123932

To Do 

• dcaegen2/deployment - updated to remove CM container build  - DONE

• BBS-Eventprocessor (dcaegen2/services) - Builds and sub-component repo will be removed post ARC meeting/review (M2). 

  • Once approved by ARC - need buld jobs and corresponding helm-charts removed/disabled.

• Integration testsuite migration 

  • Cloudify based testsuite has been disabled in gating/daily runs

  • Krzysztof K working on Bulk-PM helm test - WIP 

• Documentation update for DCAE deployment and MOD setup

@Vijay Kumar 

DIscuss PM-Mapper switch to use unauthenticated topic for below items.

• Multiple subscriber issue (DCAEGEN2-2937)

• Dmaap/Strimzi migration

• Servicemesh compliancy

PM-Mapper integration with CBS SDK inprogress; auth topics parameters can be handled as optional.

Open items: 

• PM-Mapper integration with DMAAP SDK client lib TBD with Fiachra/Dmaap team discussion 

• SliceAnalysis/KPI-MS will remain on Cambri lib for now; migration can be done if DMAAP SDK client lib will continue on Strimzi migration plan

• Solution for provisioning topic/client for unauthenticated topics in DMAAP MR any to be checked with Fiachra.

Questions for DMAAP team

• Impact on DMAAP SDK Client lib with Strimzi migration?

  • Verify if DMAAP SDK client lib can be adapted so DCAE component impact is abstracted

• Recommended library for components with direct kafka interface (HV-VES) or changing in API's (so hv-ves can be updated directly)

Other ONAP features/changes with DCAE impacts for Jakarta

@Vijay Kumar 

General discussion

• Servicemesh support - DCAE component impact on below 

1.  

   1. Allow http support (early J release) - DCAE components that rely only on HTTPS will be impacted

      1. Partial analysis completed; impact limited to 1-2 MS currently - will share the report into WIKi/next meeting - @Vijay Kumar 

   2. Components dependent on AAF cert 

      1. DR depenency on AAF is primarily on cert (auth is done local)

      2. Share the current findings and create wiki to capture the dependencies for DCAE components - @Vijay Kumar 

   3. Secure topic/feed dependency - DFC, PM-Mapper, PNF-Reg, SliceAnalysis, BBS-Ep

• Impact from DMAAP-MR → Strimzi/Kafka

  • Pub/sub API change - may need to integrate with new SDK provided by DMAAP team; all DCAE MS will have impact to align with new SDK.

    • SDK client lib need to have backward compatibility with MR (controlled via ENV/deployment property)

  • Mapping service - Alternate solution proposed by @Fiachra Corcoran /DMAAP team could be candidate solution; avoid technology dependency and can be handled generic across all MS without much impact

  • Provisioning API will change - DCAE helm template job MR provisioning template/scripts to be revisited under Strimzi/Operator

Committer support and DCAE Meetings
