What does a lock icon mean in a gitlab project?

GitLab is a popular code hosting platform that provides many useful features, including collaboration and version control. In GitLab, a common problem is seeing a lock icon on the project page.

This lock icon is actually a very useful feature in GitLab. It is called "Protected Branch". When you see it, it means that the branch is protected, i.e. only specific users or groups of users can make changes to it. This can help ensure that only authorized personnel can make changes on important or critical branches, thereby reducing the risk of unexpected or harmful changes.

In GitLab, the protected branch function can be configured through project settings. Use this feature to protect your branches from erroneous changes, unnecessary merge requests, etc. For team collaboration development projects, this is a very practical feature that can effectively manage branch access permissions and ensure more efficient collaboration among team members.

If you are a project administrator, you can choose to set a specific branch as a protected branch, specifying which users or user groups have permission to make changes to it. This can be easily done in the project's settings page by selecting the Protected Branches tab, turning on Protected on the selected branch and specifying the users or groups with access.

It is worth noting that some GitLab functions may be restricted in the protected state. For example, protected branches cannot be merged using ordinary merge strategies, and changes can only be committed through merge requests. In addition, administrators and specific group members can also force changes to be pushed to protected branches. This way, they can make necessary changes in an emergency.

To summarize, the lock icon represents GitLab’s very useful Protect Branch feature, which is crucial for protecting branches from erroneous changes and corruption. If you have just started using GitLab and have questions about this feature, it is recommended that you check the GitLab documentation or ask for help to make it more comfortable in use.
