Hi,
please navigate into your project or group settings from the menu with Settings > Usage quotas. There you should see a tabbed view with CI minutes and storage. Select the storage tab and created a screenshot from the opened view.
Here’s an example how it could look like:
In case the artifacts cause trouble here, I’d recommend looking into expire_in for job artifacts set no higher than 1 week. You can always re-trigger the build when needed.
In order to cleanup the old artifacts where this option is not applied for the already run jobs, please check the available scripts for doing bulk automation via the REST API.
Example: Remove all artifact (no expire options)
Cheers,
Michael
