Inactive project deletion (FREE SELF)

• Introduced in GitLab 15.0 with a flag named inactive_projects_deletion. Disabled by default.
• Feature flag inactive_projects_deletion removed in GitLab 15.4.

Administrators of large GitLab instances can find that over time, projects become inactive and are no longer used. These projects take up unnecessary disk space. With inactive project deletion, you can identify these projects, warn the maintainers ahead of time, and then delete the projects if they remain inactive. When an inactive project is deleted, the action generates an audit event that it was performed by the first active administrator.

For the default setting on GitLab.com, see the GitLab.com settings page.

Configure inactive project deletion

You can configure inactive projects deletion or turn it off using either:

• The GitLab API (GitLab 15.0 and later).
• The GitLab UI (GitLab 15.1 and later).

The following options are available:

• Delete inactive projects (delete_inactive_projects): Enable or disable inactive project deletion.
• Delete inactive projects that exceed (inactive_projects_min_size_mb): Minimum size (MB) of inactive projects to be considered for deletion. Projects smaller in size than this threshold aren't considered inactive.
• Delete project after (inactive_projects_delete_after_months): Minimum duration (months) after which a project is scheduled for deletion if it continues be inactive.
• Send warning email (inactive_projects_send_warning_email_after_months): Minimum duration (months) after which a deletion warning email is sent if a project continues to be inactive. The warning email is sent to users with the Owner and Maintainer roles of the inactive project. This duration must be less than the Delete project after (inactive_projects_delete_after_months) duration.

For example (using the API):

• delete_inactive_projects enabled.
• inactive_projects_min_size_mb set to 50.
• inactive_projects_delete_after_months set to 12.
• inactive_projects_send_warning_email_after_months set to 6.

In this scenario, when a project's size is:

• Less than 50 MB, the project is not considered inactive.
• Greater than 50 MB and it is inactive for:
  • More than 6 months, a deletion warning is email is sent to users with the Owner and Maintainer role on the project with the scheduled date of deletion.
  • More than 12 months, the project is scheduled for deletion.

Using the API

You can use the Application settings API to configure inactive projects.

Using the GitLab UI

Introduced in GitLab 15.1.

To configure inactive projects with the GitLab UI:

1. On the top bar, select Main menu > Admin.
2. On the left sidebar, select Settings > Repository.
3. Expand Repository maintenance.
4. In the Inactive project deletion section, configure the necessary options.
5. Select Save changes.

Determine when a project was last active

You can view a project's activities and determine when the project was last active in the following ways:

1. Go to the activity page for the project and view the date of the latest event.
2. View the last_activity_at attribute for the project using the Projects API.
3. List the visible events for the project using the Events API. View the created_at attribute of the latest event.
