Omnibus-gitlab release process

Our main goal is to make it clear which version of GitLab is in an omnibus package.

On your development machine

• Pick a tag of GitLab to package (e.g. v6.6.0).
• Create a release branch in omnibus-gitlab (e.g. 6-6-stable).
• Change the gitlab-rails version in omnibus-gitlab. In our example that would be version "v6.6.0".
• Commit the new version to the release branch

git commit -m 'Pin GitLab to v6.6.0' config/software/gitlab-rails.rb

• Create an annotated tag on omnibus-gitlab corresponding to the GitLab tag. GitLab tag v6.6.0 becomes omnibus-gitlab tag 6.6.0.omnibus.

git tag -a 6.6.0.omnibus -m 'Pin GitLab to v6.6.0'

• Push the branch and the tag to the main repository.

git push origin 6-6-stable 6.6.0.omnibus

On the build machines

• Check out the release branch of omnibus-gitlab.

git fetch
git checkout 6-6-stable

• Check the version with git describe.

git describe # Should start with 6.6.0.omnibus

• Build a package with timestamps disabled.
