=== Feature Flags ===
You can declaratively enable [https://gitlab-docs-d6a9bb.gitlab.io/ee/user/feature_flags.html Gitlab Feature Flags] using <code>extraGitlabRb</code>:<syntaxhighlight lang="nix">
{
  services.gitlab = {
    enable = true;
    extraGitlabRb = ''
      Feature.enable(:issue_date_filter)
    '';
    # Other configuration...

Then install a Gitlab on the NixOS. Make sure you set the same secrets like on the old installation.

=== Login page accessible, but root login fails after fresh install ===
Apparently, it can happen that no root user is created (or at least not fully created in the database) when building the system with a newly configured Gitlab service.
In this case, it can help to stop the Gitlab service, drop the postgres database and reboot the system. This sequence instantiates the Gitlab root user. With that, it's possible to log in with user "root" and the password configured in "initialRootPasswordFile".<syntaxhighlight lang="bash">
# stop the gitlab stack
systemctl stop gitlab.service
# drop the database
sudo -u postgres dropdb gitlab
# reboot (just starting the gitlab service again seems not to be sufficient)
sudo reboot
</syntaxhighlight>

==Notes==
Gitlab will add a user "gitlab" to your NixOS, many tutorials online point to using git over ssh with the user "git", which in our case will not match since there is no user "git". If you configure your SSH hosts with ~/.ssh/config this should work:
  Host your.selfhosted.com
    HostName your.selfhosted.com
    User gitlab
    IdentityFile /path/to/your/ssh/private/key
    # The following are optional:
    IdentitiesOnly yes
    PreferredAuthentications publickey
