Distribution ensures the experience of installing and maintaining GitLab is easy and safe for everyone. It is Distribution team's task to think about the widest variety of installation/update use-cases and provide a solution that will satisfy most needs. Distribution is there to provide the best possible experience for a user that is a novice but also a veteran when it comes to installing and maintaining software.

All work carried out by the Distribution team is public. Some exceptions apply:
Some of the team work is carried out on our development server at
dev.gitlab.org. Infrastructure overview document lists the reasons.
Unless your work is related to the security, all other work is carried out in projects on
GitLab.com. If you need to submit a sensitive issue, please use confidential issues.
If you are unsure whether something needs to remain private, check with the team Engineering Manager.
In addition to general company on-boarding and off-boarding, Distribution team has its own process to get new team members up to speed more quickly.
If you are starting with your onboarding, open an issue in Distribution team issue tracker, select
Team-onboarding template and assign the issue to yourself.
Going through the steps noted in the issue should be your top priority, higher than the general company on-boarding issue. This is because items in team on-boarding are specific to your role and it will allow you to get up-to-speed quicker.
Off-boarding should be carried out by the Engineering Manager of the team, using the appropriate issue template in the same issue tracker.
General resources available to developers are listed in the Engineering handbook.
In the Distribution team specifically, everyone should have access to the
testground project on Google Cloud Platform. If you don't have access, ask the team lead by creating issue in Distribution team issue tracker and label it
As part of the team responsibilities, team owns maintenance of infrastructure used for day to day work. For list of nodes and description of the maintenance tasks, see the infastructure and maintenance page.
Everything that is done in GitLab will end up in the supported installation methods that are distributed to users. While that sounds like the last link in the chain, it is one of the most important ones. This means that informing the Distribution team of a change in an early stage is crucial for releasing your feature. While last minute changes are inevitable and can happen, we should strive to avoid them.
We expect every team to reach out to the Distribution team before scheduling a feature in an upcoming release in the following cases:
To sum up the above list:
If you need to do
chmod, do compilation or configuration change in any part of GitLab stack, you need to reach out to the Distribution team for opinion as early as possible.
This will allow us to schedule appropriately the changes (if any) we have to make to the packages.
If a change is reported late in the release cycle or not reported at all, your feature/change might not be shipped within the release.
If you have any doubt whether your change will have an impact on the Distribution team, don't hesitate to ping us in your issue and we'll gladly help.
