This guide is strongly based on the Prometheus release instructions.
We use Semantic Versioning.
We maintain a separate branch for each minor release, named release-<major>.<minor>, e.g. release-1.1, release-2.0.
The usual flow is to merge new features and changes into the master branch and to merge bug fixes into the latest release branch. Bug fixes are then merged into master from the latest release branch. The master branch should always contain all commits from the latest release branch.
If a bug fix got accidentally merged into master, cherry-pick commits have to be created in the latest release branch, which then have to be merged back into master. Try to avoid that situation.
Maintaining the release branches for older minor releases happens on a best effort basis.
For a new major or minor release, work from the main branch. For a patch release, work in the branch of the minor release you want to patch (e.g. release-0.1 if you're releasing v0.1.1).
Add an entry for the new version to the CHANGELOG.md file. Entries in the CHANGELOG.md should be in this order:
[CHANGE][FEATURE][ENHANCEMENT][BUGFIX]
Create a PR for the changes to be reviewed.
For new minor and major releases, create the release-<major>.<minor> branch starting at the PR merge commit.
From now on, all work happens on the release-<major>.<minor> branch.
Bump the version in the VERSION file in the root of the repository.
Regenerate setup.yaml based on latest code and then commit the changed bundle.yaml to the release-<major>.<minor> branch:
make manifests
git add ./
git commit -s -m "regenerate setup.yaml"
git pushImages will be automatically built and pushed whenever code changes or a tag is created. If users want to build images manually, use the following command:
make build-op-amd64 -e FO_IMG=<image of fluent operator>
docker push <image of fluent operator>
make build-fb-amd64 -e FB_IMG=<image of fluent bit>
docker push <image of fluent bit>
make build-fd-amd64 -e FD_IMG=<image of fluentd>
docker push <image of fluentd>Tag the new release with a tag named v<major>.<minor>.<patch>, e.g. v2.1.3. Note the v prefix. You can do the tagging on the commandline:
tag="$(< VERSION)"
git tag -a "${tag}" -m "${tag}"
git push origin "${tag}"Commit all the changes.
Finally, create a new release:
- Go to https://github.com/fluent/fluent-operator/releases/new.
- Associate the new release with the previously pushed tag.
- Add release notes based on
CHANGELOG.md. - Add file
setup.yamlfrommanifests/setup/setup.yamland then click "Publish release".
For patch releases, cherry-pick the commits from the release branch into the master branch.
