Ensure branch deletions are denied

中レベル 1自動gitlab

説明

Ensure that users with only push access are incapable of deleting a protected branch. When enabling deletion of a protected branch, any user with at least push access to the repository can delete a branch. This can be potentially dangerous, as a simple human mistake or a hacked account can lead to data loss if a branch is deleted. It is therefore crucial to prevent such incidents by denying protected branch deletion.

These settings are inherited by all projects in the group and can’t be overridden by project settings. If a specific branch is configured with Allowed to force push settings at both the group and project levels, the Allowed to force push setting at the project level is ignored in favor of the group level setting. Prerequisites: - You must have the Owner role in the group. To protect a branch for all the projects in a group: 1. On the left sidebar, select Search or go to and find your group. 2.
