Summary

  • Add a Renovate custom regex manager to detect and pin the digest of ghcr.io/vexxhost/build-utils in the --mount=type=bind,from= syntax
  • This ensures Docker layer cache invalidation when build-utils is updated

Background

The --mount=type=bind,from=image:tag syntax within RUN commands isn't detected by Renovate's default Docker manager. This custom manager uses regex to match the pattern and allows Renovate to pin the digest.

Once merged, Renovate should create a follow-up PR to pin the actual digest.

Test plan

  • Merge this PR
  • Verify Renovate creates a PR to pin the build-utils digest
