A release of grype comprises:
- a new semver git tag from the current tip of the main branch
- a new github release with a changelog and archived binary assets
- docker images published to
ghcr.io
anddockerhub
, including multi architecture images + manifest anchore/homebrew-grype
tap updated to point to assets in the latest github release
Ideally releasing should be done often with small increments when possible. Unless a breaking change is blocking the release, or no fixes/features have been merged, a good target release cadence is between every 1 or 2 weeks.
This release process itself should be as automated as possible, and has only a few steps:
-
Trigger a new release with
make release
. At this point you'll see a preview changelog in the terminal. If you're happy with the changelog, pressy
to continue, otherwise you can abort and adjust the labels on the PRs and issues to be included in the release and re-run the release trigger command. -
A release admin must approve the release on the GitHub Actions release pipeline run page. Once approved, the release pipeline will generate all assets and publish a GitHub Release.
If a release is found to be problematic, it can be retracted with the following steps:
- Deleting the GitHub Release
- Untag the docker images in the
ghcr.io
anddocker.io
registries - Revert the brew formula in
anchore/homebrew-grype
to point to the previous release - Add a new
retract
entry in the go.mod for the versioned release
Note: do not delete release tags from the git repository since there may already be references to the release in the go proxy, which will cause confusion when trying to reuse the tag later (the H1 hash will not match and there will be a warning when users try to pull the new release).
