Demo/Discussion -Deployment use cases  Sridhar Rao

• PM rApp in NONRTRIC ranpm
  • Does it use the rApp catalog?
    • John Keeney (Ericsson EST) - Not sure that rApp is a 'full' rApp. Suggest using some of the other sample rApps in https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/plt/rappmanager.git;a=tree;f=sample-rapp-generator , the work we did with AIMLFW demos last year.
    • Current rApp Catalog doesn't really do anything. Will probably deprecate it: https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric%2Fplt%2Frappcatalogue.git;a=summary 
    • Best to use rAppManager as rAppCatalog for onboarded rApps.
• Replacing DMaaP-MR with Strimzi Kafka bridge
  • John Keeney (Ericsson EST) - We looked at it, but decided to use native kafka (strimzi) instead
    • Martin Skorupski mentioned that http messaging is handy between locations - esp with the single-namespace restriction in strimzi.
  • John Keeney (Ericsson EST) - I think native kafka is already implemented in VES collector - just configure the topic, then native kafka is used?
    • Ref https://gerrit.onap.org/r/c/dcaegen2/services/sdk/+/135701 
• OAM K8s solutions/deployment? Sridhar Rao, Alex Stancu Martin Skorupski & Alex Dehn discussing by email.

Other Questions / Comments / AOB:

• Karthick N Srinivasa Raghavan - Keysight - How to use O1-CM from an rApp?
  
  • John Keeney (Ericsson EST) no concrete example yet. But SDNC NBI is registered as a discoverable service (in recent IT/DEP SMO deployment), so just discover & use as per any other service. The SDNC NBI/API will be based on the yang models used in SDNC.
  • SME in J-Release is very old - suggest you should use K-Release. And rApp samples in K-Release would be much better.
