Best practices for the usage of the CentOS namespace on gitlab

This document highlights the best practices SIGs interested in using the CentOS namespace on gitlab.com should follow.

Login in

The first thing to understand is that gitlab will "link" an existing account with third party authentication system. In other words, you need to have a gitlab account and be logged in onto gitlab.com before you can associate your account with the CentOS Account System (ACO).

So if you do not have a gitlab account, create one. Then visit the following link https://id.centos.org/gitlab to associate your account with CentOS' Account System.

From there on, everytime you visit this link, your group membership defined in ACO, will be refreshed on gitlab.

Content

Any and all content hosted on gitlab.com should follow the Requirements the CentOS project has specified for SIGs: https://wiki.centos.org/SpecialInterestGroup#Requirements

Access

It is expected that access levels are managed via groups on accounts.centos.org (ACO). There are different ways this can be achieved.

Simple case

For SIGs who are fine with everyone getting the same level of access, a single group can be created on https://accounts.centos.org where all the SIG members will be added. This group can then be mapped to that SIG’s namespace under gitlab.com/centos and be given owner access level.

This means, everyone added to this group on accounts.centos.org will be granted owner access to each and every project placed under that SIG’s namespace. This also means, that anyone not in this group will have no access at all.

More complex case

For SIGs who want or need a more fine tuned model, it is recommended that they create a groups namespace under the SIG’s namespace. In the group namespace will be placed all the groups needed by the SIG and each of this group will be mapped to a corresponding group on ACO. There should be no project under the groups namespace. The groups can then be given access to any project and the access level of the group can be picked on a per-project basis.

Here is an example of the structure recommended for the complex case:

SIG's namespace
│
├── groups
│   ├── group1-developers [grp1]
│   ├── group2-maintainers [grp2]
│   └── sig [sg]
│
├── rpms
│   └── pkg [grp1+grp2]
│
├── src
│   └──source_tree [grp1]
│
└── sig [sg]

Group membership refresh

To login via ACO on gitlab.com, you must use the following link: https://id.centos.org/gitlab

Group memberships are refreshed upon login into gitlab.com. So if someone is added to a group in ACO, they will need to visit that link again: XXX to have their membership refreshed.

Group names

For SIGs using the more complex case where multiple groups are required or desired, it is expected that the extra groups created on ACO to manage access on gitlab.com should follow the corresponding pattern: gitlab-<fedora|centos>-<sig>(-<name>)

Some examples:

• gitlab-centos-hypsercale-maintainers
• gitlab-centos-automotive-kernel-maintainer
• gitlab-centos-automotive-sig-owner
• gitlab-centos-docs-members
• …

Requesting a namespace or a group
