Mirror github to Gitlab

Chad Carbert answer still applies but just want to add extra for version 7.0.0.

Open "/etc/gitlab/gitlab.rb" in your text editor where currently I have external_url http://127.0.0.1/ or similar to that. I may need to change external_url with dns including port number (eg. 'http://gitlab.com.local:81/') then reconfigure using command "sudo gitlab-ctl reconfigure" Gitlab is now working on port 81.

Step by step:

1. sudo -e /etc/gitlab/gitlab.rb
2. Change external_url from yourdomain.com to yourdomain.com:9999
9999 -> Port you want it to run
3. sudo gitlab-ctl reconfigure

Gitlab 9.0 now has support for subgroups, with a few limitations. You can create up to 20 levels of subgroups. Users can be assigned to subgroups and projects can be created in them. Users assigned to the parent group have the same permission for all descendant groups from that parent.

Rules (from the docs):

• You need to be an Owner of a group in order to be able to create a subgroup.
• Some words are reserved and may not be used as subgroup names.
• Permissions inherited from a parent group can only be changed in the parent, not in the child.
• Permissions can be overridden in the child group by explicitly adding the user to the subgroup again.

Additional current limitations (from the docs -- these may be fixed in future releases):

• GitLab Pages are not currently working for projects hosted under a subgroup. That means that only projects hosted under the first parent group will work.
• Group level labels don't work in subgroups / sub projects
• It is not possible to share a project with a group that's an ancestor of the group the project is in. That means you can only share as you walk down the hierarchy. For example, group/subgroup01/project cannot be shared with group, but can be shared with group/subgroup02 or group/subgroup01/subgroup03.

Original answer for older versions:

No, it's not currently supported to create subgroups in Gitlab. (Note that this is also not supported in most other Git hosting sites that I know of, including Github, Bitbucket, and Gitorious.)

On my server, our workaround is to use dots in the name, for example "group1.group2".

You could suggest the feature, but I doubt that it will go anywhere unless you sponsor it or find someone to implement it.
