The tagging operation (annotated and signed) needs to be done manually:

TAG=25.0.0
RELEASE_ID=2024.2

Release candidate

git tag -u $KEYID -s -a -m 'RC release for $MASTER_RELEASE $TAG' ${TAG}.0rc1 master
git push --tags gerrit

We need to only push to Gerrit repo, the packstack-upload-git-mirror Zuul job will then push it to GH mirror
Check the jobs in pre-release pipeline after pushing the tag https://zuul.opendev.org/t/openstack/builds?project=x%2Fpackstack&pipeline=pre-release&skip=0&limit=100

Create branch

ssh review.opendev.org gerrit create-branch x/packstack stable/${RELEASE_ID} master

and submit patch e.g https://review.opendev.org/c/x/packstack/+/931629

Final Release (when all packages promoted to -release)

git tag -u $KEYID -s -a -m 'Final release for $MASTER_RELEASE $TAG' ${TAG} stable/${RELEASE_ID}
git push --tags gerrit
