How to use GitLab for project version release and rollback

Introduction:

In the software development process, project version release and rollback are An essential piece of work for the development team. GitLab is a powerful version control system that provides rich functions and tools to manage and publish different versions of a project. This article will introduce how to use GitLab for project version release and rollback, and provide specific code examples.

1. Project version release

1. Create a new branch
   On GitLab, each project has a master branch (usually master or main). When a new version needs to be released, we need to create a new branch for development and testing. You can create a new branch locally and push it to GitLab with the following command:

$ git checkout -b new_branch
$ git push origin new_branch

2. Development and Testing
   Develop and test on the new branch to ensure the stability of the project There are no issues with new features or bug fixes and are verified through various testing methods. At this stage, the code can be submitted to GitLab multiple times and merged into the main branch through Merge Request. In GitLab's Merge Request page, you can view and review other people's code changes.
3. Review and merge branches
   When all development and testing are completed, a code review is required. Members of the project team can be arranged to review and evaluate the code of the new branch. In GitLab, code merging can be completed through Merge Request. Use Merge Request to easily view and compare code changes, and conduct online reviews and comments.
4. Version release
   When the code review passes, the new branch can be merged into the main branch and a new version released. You can merge the new branch into the main branch through the following command:

$ git checkout main
$ git merge --no-ff new_branch
$ git push origin main

2. Project version rollback

1. View the submission history
   On GitLab, you can pass Commit history to view the project's version change history. You can use the following command to view the commit history of the branch:

$ git log

2. Rollback to a certain commit
   When you need to rollback to a specific version, you can use the following command to Roll back the branch to the specified commit:

$ git revert <commit_id>
$ git push origin main

Where, <commit_id></commit_id> is the ID of the commit to be rolled back.

3. Create a new version
   When the rollback is completed, the branch can be merged into the main branch and a new version released. You can use the following command to merge the rolled-back branch into the main branch:

$ git checkout main
$ git merge --no-ff rolled_back_branch
$ git push origin main

where rolled_back_branch is the name of the rolled-back branch.

Conclusion:

GitLab is a powerful version control system. By using GitLab, we can easily release and roll back the version of the project. When releasing a version, new branches need to be created, developed and tested, branches reviewed and merged, and finally merged into the master branch. When rolling back a version, you can view the commit history, roll back to the specified commit, and merge the rolled-back code into the main branch. By rationally using GitLab's functions and tools, the efficiency of project development and management can be improved.
