MADDEN planning document

Zoom link

Gitlab group

Actions items:

• organise projects/group in ET gitlab -> done (Paul)
• We need a presentation for the Bologna workshop, MADDEN + ETAP, will prepare two separate sets of slides (Federica and Paul) then decide
• On-going:
  • Lia reports an issue about rights for writing in Rucio. Andres cannot write becase his rucio account is for "users" and users can only write in their own scope (rucio default) -> Lia needs to open an issue about this - no progress since last week
    • can be fixed by giving Andres rucio admin rights
    • on the long term, we need to implement "publisher" role, as in Virgo, which is a user that can write in all scopes, but is not a full admin
  • Andres uploaded MDC data to RSE Louvain: 
    
    • Paul cannot read them, Lia can. Solved, just different scope from Escape MDC1v2 vs ET_OSB_MDC1v2:*
  • Open an issue about monitoring: Grafana dashboards and/or webUi
  • Open an issue about rules/documentation/daemons
  • RSE@PIC - issue - no progress
    • asked Gonzalo for 20 TB (Andres), sent list of DNs to be authorised, waiting for PIC
  • token authentication (Lia) -  issue
    • rucio whoami works 
    • working on authorization on xrootd with tokens
    • Andres will share his configuration for tokens in UCLouvain
    • Andres has a dockerfile to build a container with tokens -> open a MR to Nikita's repo to add this
  • Set up CE rucio server (Nikita) - issue - on-going (Nikita has some issues with permissions)
  • Distribuite rucio client (Nikita) - issue 
    
    • issue with uploading to registry on ET Gitlab.
      • Gary was contacted but the ET gitlab instance does not allow upload images.
      • Upload on dockerhub not good because of the limitation on number of pulls -> add it for discussion next week?
