Instance-level merge request approval rules

Introduced in GitLab Premium 12.8.

Merge request approvals rules prevent users overriding certain settings on a project level. When configured, only administrators can change these settings on a project level if they are enabled at an instance level.

To enable merge request approval rules for an instance:

  1. Navigate to Admin Area > Push Rules and expand Merge requests approvals.
  2. Set the required rule.
  3. Click Save changes.

GitLab administrators can later override these settings in a project’s settings.

Available rules

Merge request approval rules that can be set at an instance level are:

  • Prevent approval of merge requests by merge request author. Prevents project maintainers from allowing request authors to merge their own merge requests.
  • Prevent approval of merge requests by merge request committers. Prevents project maintainers from allowing users to approve merge requests if they have submitted any commits to the source branch.
  • Prevent users from modifying merge request approvers list. Prevents project maintainers from allowing users to modify the approvers list in project settings or in individual merge requests.
