fix: make Dependabot see the composite actions - #4
Merged

Conversation
The `/.github/actions/**` glob was accepted by Dependabot but matched nothing. Its first run after v1.0.0 checked only actions/checkout and zizmorcore/zizmor-action, both of which live in .github/workflows/ — the five docker/* pins in the composite actions were never looked at, and docker/build-push-action is pinned at v6 while v7.3.0 exists, so an update would certainly have been reported had they been seen. Left unfixed, the pins this repo exists to hold would never be told to move: a SHA pin without a working bump bot is a frozen version, which is the failure the cooldown and the bot were meant to prevent together. Listing each action directory explicitly is what the github-actions ecosystem actually resolves. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Listing each action directory by hand means a new action silently goes unscanned until someone remembers to add a line - the failure this config exists to prevent. A glob does work; the earlier attempt used the wrong one. Dependabot expands these with Ruby's Dir.glob, where a bare ** behaves as * and matches a single level, so /.github/actions/** resolved to .github/actions/docker - a directory holding no action.yml - and matched nothing. The recursive form is **/*. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Follow-up to #3, which flagged this as "verify on the first run". The first run has now happened, and the answer is that it did not work.
What went wrong
#3configured Dependabot with:The glob was accepted — it appears verbatim in the job definition (
"directories":["/.","/.github/actions/**"]) — but it matched nothing. Both runs after the v1.0.0 merge checked exactly two dependencies:Both live in
.github/workflows/. None of the fivedocker/*pins were looked at. That is not ambiguous:docker/build-push-actionis pinned atv6andv7.3.0exists, so an available update would have been reported had Dependabot seen the file.Why it matters
The pins are the point of this repository. A SHA pin without a working bump bot is a frozen version that nobody is told to move — including a frozen vulnerable one. The cooldown and the bot only do their job as a pair.
The fix
List each action directory explicitly. The
github-actionsecosystem resolvesaction.ymlin a named directory; it does not expand**into one.Verifying
Dependabot re-runs when this config changes on the default branch, so the next run's log after merge should show
docker/build-push-action,docker/login-action,docker/metadata-action,docker/setup-buildx-actionanddocker/setup-qemu-actionbeing checked — and should open bump PRs for the majors they are behind. If it still misses them, Renovate is the fallback.🤖 Generated with Claude Code
