      • Seems to be more of a planning workshop than a developers session. 
        • Still hope to be able to make this meeting relevant for developers - with some demos maybe
          
        • Scope is still quite unclear, & uncertain if we should have demos etc. possible just videos if a suitable opportunity arises

Integration (bimo fransiscus asisi)

AOB:

• Github Actions / Workflows Migration (Matt Watkins, John Keeney (Ericsson EST), Martin Skorupski):

  • Matt & Ravi have solved issue for OAM GHA for container upload to nexus 

  • Still working on uploading / releasing it/dep helm charts/scripts for SMO Install  
    
    

• CVEs:

  • Intern now working on CVE checking (now) & fixing (soon). (Sridhar Rao) 
  • More tool support needed for conditional checking etc. 
  • No update - need tool support/scanning for LF. Talking with Sridhar Rao & Matt Watkins
  • Proposal for discussion between PTLs & later approval from TOC: Discussion about updates of the parent CVE page 
  • Code not intended to be use in production should be tagged with a disclaimer in some way
  • Should be at a repo-level or directory level - suggest directory level.
  • Sample can be seen at https://gerrit.o-ran-sc.org/r/c/oam/+/14745
    • Merged.  
    • John Keeney (Ericsson EST) added the human-readable parts to some NONRTRIC repos - but machine interpretable part still needs tool support, discussion & may change. 
      • e.g. https://gerrit.o-ran-sc.org/r/c/nonrtric/plt/rappmanager/+/14826 
    • Sridhar Rao. Martin Skorupski will discuss with Matt Watkins & teams.  
      
      

• Winlab servers (OSC Test lab) (Martin Skorupski, Ivan Seskar)

  • Docker hub - max pull limits being hit (Ivan Seskar, Aravindhan Ayyanathan (Ericsson EST), Martin Skorupski)
    
    • Issue solved. Need to change to point to OSC/ONAP nexus instead of dockerhub. Automatically triggers mirroring in nexus. 
      • Some (few) images still needs to come from dockerhub & other places - so cannot be mirrored. But those are few & less likely to go over the pull threshold. 
        
        

• PRB utilization use case (rApp & ML) (Sunil N)

  • Still working on approval to release etc. 
  • Will demo next week (or worst case the following week)
    • Still have a couple of issues outstanding. Coming soon!  
  • Working with sample/sim data to train a model, then deploy as a rApp
  • Good use case to progress AIMLFW integration with rApp toolchain (Sunil N, subhash, John Keeney (Ericsson EST)
    • Training, Model deployment & inference service LCM. 
      • e.g. would like to see different options for model & inference service containment & LCM - both 'inside/part-of' to rApp, or outside rApp using AIMLFW functions.  
        
        

• OFH M-Plane PM (Sridhar Rao)

  • O-RU File-based Performance Management

  • PM Metrics from O-RU - O-RU is pushing the files -

    • Needs a parser - alot of work
    • O-RAN Management Plane Specification v18.00 18.0 – LINK – Section 10.3.2 – File Upload
    • Would be good to see some sample files ... 

  • Work in progress - keep topic open for now
    
    

• CVEs & Updates to OSC Dockerfiles (Sridhar Rao, mdimado, Jitmisra) 

  • Some updates can be suggested for OSC dockerfiles based on recent work from interns. 
  • Ref: https://github.com/sknrao/oransc-sanity 
  • Suggestion: updates can be contributed as gerrit reviews for review. 
    • Suggest that some effort is made to test the updates - simply building the image is unlikely to be sufficient. Some indication of tests performed or verification would be helpful/needed, especially for repos not frequently/recently updated.  
      
      

• Experimenting with O2-IMS & Nephio (Sridhar Rao & John Keeney (Ericsson EST) & Vishal Varvate)

  • Vishal working on O2-IMS operator & O2-IMS spec update

      • https://github.com/nephio-project/api/pull/69
  • Discussion ongoing in O-RAN Alliance about FOCOM usecase for provisioning & NBI - which could possibly use work on O2-IMS work in nephio. 
  • Sridhar Rao: Struggling with non-kind o-cloud in nephio
    • Work in progress: https://github.com/nephio-project/nephio/issues/576
