Use cases

• GlastRelease - frozen on RHEL6
  • L1 processing, reprocessing in SLAC batch farm
    • RHEL6 container on a RHEL7 host
    • do FT1, FT2 files go to xrootd? (Warren)
    • separate containers for L1? Maybe not an issue if we can preload batch nodes. We're guessing ~5 GB image.
  • Simulations at Lyon, SLAC, GRID
    • maybe the same as for SLAC - check with Samuel for details
  • Developers & Users
    • maybe separate versions for debug symbols and source for developers. Could be on-demand production of this version.
  • Release Manager or manual builds
• Science Tools
  • Caching big files (e.g. templates) in container image. Need a strategy with SCS for this for how containers are cached.
