This document describes how to release Flagger.

Release

To release a new Flagger version (e.g. 2.0.0) follow these steps:

• create a branch git checkout -b prep-2.0.0

• set the version in code and manifests TAG=2.0.0 make version-set

• commit changes and merge PR

• checkout master git checkout main && git pull

• tag master make release

CI

After the tag has been pushed to GitHub, the CI release pipeline does the following:

• creates a GitHub release

• pushes the Flagger binary and change log to GitHub release

• pushes the Flagger container image to Docker Hub

• pushes the Helm chart to github-pages branch

• GitHub pages publishes the new chart version on the Helm repository

Docs

The documentation website is built from the docs branch.

After a Flagger release, publish the docs with:

• git checkout main && git pull

• git checkout docs

• git rebase main

• git push origin docs
