ci(release): route the signing jobs to the Mac that holds the keychain - #2010
Merged
Merged
Conversation
build-release-macos-arm64 and sign-macos-artifacts unlock the Developer ID keychain, which only one self-hosted Mac holds. They ran on the base self-hosted macOS labels, so a second Mac in the fleet could take one and fail the release. Require the minimal-signing label on both, declare it for actionlint, and add docs/internal/macos-runner-setup.md: the runbook for adding a Mac to the fleet.

Review comments at @.github/workflows/release.yml:
- Line 456: The runner changes conflict with the repository’s workflow-file
restriction; use an approved mechanism outside the workflow file to route both
jobs, or obtain approval before changing it. At .github/workflows/release.yml
lines 456-456, update runner selection for build-release-macos-arm64 through
that permitted mechanism; at .github/workflows/release.yml lines 693-693, do the
same for sign-macos-artifacts.
Review comments at @docs/internal/macos-runner-setup.md:
- Around line 199-207: Update the “Take a Mac offline” maintenance section to
state that setting RUN_MACOS_CI to false skips the macOS build and signing jobs
and therefore skips the release without publishing one; clarify that CI and
smoke aggregators still pass when those jobs are skipped.
