build-cran-binaries/.crow/retire-slot.yaml

# Delete a retired slot's objects from the bucket.
#
# The config half is a commit, so it runs on a workstation:
#   just retire-slot <codename> --apply
#
# This half needs the B2 credentials, which only exist in CI.
# `local/retire-slot.R` refuses any slot still listed in `local.rpkgs_slots`,
# so this cannot delete a live slot. Both architectures go together.
#
# Dry run unless RETIRE_APPLY is 'yes':
#
#   crow pipeline create devxy/build-cran-binaries --branch main \
#     --var retire_slot=alpine322 --var RETIRE_APPLY=yes

variables:
  # A manual pipeline creation instantiates every file in .crow/, so the
  # default must be a value the script never accepts.

    description: "Codename of the slot to retire (e.g. alpine322), or 'none'."
