How to protect branches in gitlab

GitLab is a very popular version control system and a commonly used version management tool in the field of web development. It can help teams manage project code efficiently. In GitLab, branches are one of the very important concepts. Correct branch management can ensure the smooth progress of team projects. However, during the actual development process, security issues such as branches being maliciously deleted or illegally modified may occur. So, how does GitLab protect branches? This article will introduce some methods and techniques.

1. Restrict user branch deletion permissions

In most cases, branches are not as important as main branches or trunk branches, but in many development teams, branches do have a very important role. Useful because branches involve specific versions or code changes. In response to this situation, we can protect the team's code security by restricting the user's branch deletion permissions.

In GitLab, you can limit the user's branch deletion permissions by following the following steps:

1. Select the "Settings" button in the GitLab navigation bar, and then select "Members".

2. Find the member whose permissions you want to modify in the member list.

3. Change the "Access Level" of this member to "Developer".

4. Select "Protect Branch" under "Branch Access Level".

5. In the protected branch page, select the name of the branch to be protected.

6. Check the "Delete Branch" option and save the changes.

In this way, during operation, as long as members do not have the authority to delete branches, they cannot perform branch deletion operations, which can greatly reduce code loss caused by misoperation.

2. Prevent unauthorized branch merging

GitLab branches can be merged, which is a very convenient function, but without certain preventive measures, illegal merging may occur. , which in turn leads to code security issues. In order to prevent unauthorized branch merging, we can make the following settings:

1. Select the "Settings" button in the GitLab navigation bar, and then select "Warehouse".

2. On the warehouse page, select "Protect Branch".

3. In the protected branch page, select the name of the branch to be protected, and then check "Force Merge".

4. Save changes.

In this way, only administrators or specific code reviewers can perform branch merging operations after approval, ensuring the security and correctness of the code and avoiding the merging of unauthorized branches.

3. Enable branch access control

The access control mechanism in GitLab is very flexible, and branch security can be protected through the access control mechanism. In GitLab, you can use the following access control mechanism to protect branches:

1. Default branch: You can set a default branch and set the protection method of the default branch.

2. Branch permissions: Branch permissions can be set in the project, and branch access permissions of specific users or user groups can be restricted.

3. Core branch: You can set up a core branch and disable the "automatically delete branches after merging" option in the branches that need to be protected.

4. Accessibility: The accessibility of the project can be set from three levels: private, internal and public.

Through the above access control mechanism, the security of branches can be ensured, access permissions can be restricted, and losses caused by malicious operations can be reduced.

Summary

In GitLab, protecting branches is very important, because once a branch is illegally deleted or modified, it will have a great impact on the progress of the project and the quality of the code. By setting permissions, access control, preventing illegal merges and other measures, the team's code security can be effectively protected. Therefore, in the actual development process, we need to pay attention to these methods and techniques of protecting branches to ensure the safety and reliability of the project.
