GitLab

To use git for your own and team projects, DTU Compute is providing a GitLab instance with all the benefits it offers. Primarily a place for your repositories, other features are or will become available.


Login with your DTU credentials here: https://lab.compute.dtu.dk


Add your public keys

To access your private repositories, add your public SSH-key to your GitLab account.
If you don't have a SSH-key, on Linux/MacOS you can use this command in your favourite shell:

ssh-keygen

Press Enter 3 times to create a password-less key pair, located in:

$HOME/.ssh/id_rsa
$HOME/.ssh/id_rsa.pub

The file id_rsa.pub is your public key which you can share with other systems, including DTU Compute's GitLab.


To add your public key in GitLab, follow these steps after login:


1) In the top-right corner click your user icon
2) Click Settings and on the left-hand panel click SSH Keys
3) Follow the instructions from here

Give access to other users

To share a repository with other users, the user you want to add has to login to GitLab first. Then you can find and add them as a member of your project.


1) Select your project you want to share
2) In the left-hand panel select Settings -> Members
3) Under Select members to invite search for the username

Migrating from Gitolite to GitLab

Our existing Gitolite server (git.compute.dtu.dk) is considered deprecated, and everyone with active repositories there are encouraged to migrate. This can be done from a local PC with a cloned repo.

Migrating a repo requires a bit of manual work, but not much. What it basically comes down to, is moving the origin from Gitolite to GitLab. Here are the steps described as simple as possible:

  • Make sure your locally cloned repo - incl. branches, tags, etc. - is up to date with origin
  • Create a new repository on GitLab using the same name as the repo you want to move
  • Add a new remote using the URL from GitLab, and push everything to this remote
  • Remove all references to the old remote (Gitolite)
  • Rename the new remote to origin
  • In GitLab add the users you want to share the project with.

Steps described

As is shown above, it is pretty straight forward to move a repository, but as always the details are important. Here the steps will be described a bit more together with the commands to use.
