OSG Software Team

  • Kubernetes hackathon

    • AI (Brian): upgrade Prometheus
    • AI (Mat): EL9 repo?
    • AI (Mat): GLBRC origins
    • AI (Mat): one of sealed-secrets or cert-manager upgrades
    • AI (Matt): IGWN CVMFS on the PATh Facility
    • AI (Matt): PATh FIU IPv6

  • OSG 24:

    • Package builds assigned!
    • AI (Matt): ARM OSPool EP containers?
      • Need to debug x86_64 Singularity test failures causes by adding arm
      • Add CPU/memory limiting
      • Custom GitHub action for building Docker images needs to be fixed for multiarch builds;
    • AI (Matt): Merge Mat's repo-scripts PRs for updating the repo server; need to put osg-release for OSG 24 on repo to start testing

Discussion

  • OSPool ARM Singularity images (for payload jobs) do not exist -- Mat, Mats need to design a scheme for distinguishing them from x86_64

  • Kuantifier (Matt): Suggested Prometheus metrics for Kuantifier are easy to access, but the required config changes are not well documented which suggests a low usage rate across the community. The current Kuantifier user base is well versed in Kubernetes so this should be fine for now.

Support Update

  • Many support requests are coming in from IGWN because they want to use the PATh Facility
  • Mat (ComputeCanada-Cedar for IGWN): Singularity support wasn't being enabled because GlideinWMS startup scripts were requiring the default images to be from CVMFS. Fixed in frontend config.
