Stack from ghstack (oldest at bottom):
Impact: OSDC clusters.yaml + new Renovate workflow
Risk: low
What
Bootstraps Renovate for OSDC. Adds a
renovate.jsonconfig that detectsthe runner image tag pinned in
osdc/clusters.yaml, a scheduled GitHubActions workflow that runs Renovate, and a
renovate: keep markercomment on the defaults'
runner_image_tagline so the regex matchesonly the defaults (not per-cluster overrides).
Why
We pin
ghcr.io/actions/actions-runnerand want patch/minor bumps toflow through automatically with a normal PR review path — instead of
relying on manual sweeps.
How
osdc/renovate.json: docker datasource targeting the marker line,with strict regex extraction so per-cluster overrides stay untouched.
.github/workflows/osdc-renovate.yml: scheduled (and manuallydispatchable) workflow that runs Renovate. Opens PRs only; auto-merge
/ auto-deploy are wired up in subsequent commits.
osdc/clusters.yaml: adds the marker comment on the defaults line.Changes
osdc/renovate.json: new..github/workflows/osdc-renovate.yml: new.osdc/clusters.yaml: 1 comment + 1 line reflow on the defaults entry.Notes
This commit only opens Renovate PRs. The auto-approve and auto-deploy
workflows land in later commits in this stack.
Testing
osdc-renovate.ymlonce landed; confirm a PR isopened if a newer
actions/actions-runnertag exists upstream.Signed-off-by: Jean Schmidt contato@jschmidt.me
