After pushing the tenant image to registry.fly.io, the workflow now lists all running/stopped molecule-tenant machines and updates each to the newly pushed image tag. Gracefully skips if no machines exist (control plane provisions on demand). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# The Mac mini self-hosted runner runs as a non-interactive
|
|
# launchd service; docker/login-action's default credential store
|
|
# is the macOS Keychain, which raises
|
|
# error storing credentials - err: exit status 1, out:
|
|
# `User interaction is not allowed. (-25308)`
|
|
# without an unlocked desktop session.
|
|
#
|
|
# Point DOCKER_CONFIG at a per-run temp dir. IMPORTANT: writing
|
|
# `{"auths": {}}` alone is NOT enough — Docker on macOS picks up
|
|
# `osxkeychain` as the default credential store even when
|
|
# config.json doesn't declare one, inheriting from Docker
|
|
# Desktop's bundled credsStore binding. We must explicitly set
|
|
# `credsStore` to an empty string AND clear `credHelpers` so the
|
|
# login step writes credentials into the auths map of this
|
|
# disposable config.json rather than reaching for the keychain.
|
|
# (First tried in #273 without the empty-credsStore line; #319
|
|
# + #322 merges showed it still regressed.)
|
|
#
|
|
# Plus diagnostics: print the docker path so a future EACCES on
|
|
# /usr/local/bin/docker surfaces in the log instead of via a
|
|
# cryptic docker-login failure mid-step.
