Are you gearing up for a DevOps interview that involves GitLab? Whether you’re a fresh graduate entering the tech industry or a developer looking to dive into DevOps practices, mastering GitLab is essential. In this blog post, we’ll explore the top 20 GitLab interview questions tailored for freshers entering the exciting world of DevOps.
1. What is GitLab, and how does it differ from other version control systems?
GitLab is a web-based Git repository manager providing source code management, continuous integration, and more. Unlike other systems, GitLab is an end-to-end solution with a built-in CI/CD pipeline and features like issue tracking and code review.
2. Explain the purpose of the “.gitlab-ci.yml” file.
This YAML file defines the CI/CD pipeline configuration in GitLab. It outlines the stages, jobs, and scripts to execute during the pipeline process.
3. What is GitLab Runner, and how does it relate to the CI/CD pipeline?
GitLab Runner is an agent that runs jobs defined in the “.gitlab-ci.yml” file. It can be installed on separate machines or used with shared runners provided by GitLab.
4. Differentiate between Git and GitLab.
Git is a distributed version control system, while GitLab is a platform built on top of Git. Git handles version control, while GitLab provides additional features such as issue tracking, collaboration tools, and CI/CD.
5. How do you create a new branch in GitLab?
To create a new branch in GitLab, you can use the following command:
git checkout -b new-branch-name
git push origin new-branch-name
6. Explain the concept of forking in GitLab.
Forking in GitLab involves creating a copy of a repository under your account. This allows you to make changes independently and propose those changes back to the original repository via merge requests.
7. What is GitLab CI/CD, and how does it benefit the development process?
GitLab CI/CD is an integrated continuous integration and continuous delivery system. It automates the testing and deployment of code changes, ensuring faster and more reliable software delivery.
8. Describe the purpose of a GitLab merge request.
A merge request in GitLab is a request to merge changes from one branch into another. It provides a platform for code review, collaboration, and discussion before changes are merged.
9. How do you revert a commit in GitLab?
To revert a commit in GitLab, you can use the following command:
git revert <commit-hash>
git push origin <branch-name>
10. Explain GitLab’s role in version control collaboration.
GitLab facilitates version control collaboration by providing a centralized platform for developers to manage and coordinate changes. It includes features like code review, issue tracking, and merge requests to enhance collaboration.

11. How can you secure a GitLab repository?
GitLab offers several security features, including access controls, authentication methods, and repository visibility settings. Additionally, you can enable features like container scanning and dependency scanning for enhanced security.
12. Discuss the importance of runners in GitLab CI/CD.
Runners in GitLab CI/CD execute jobs defined in the pipeline. They can be shared runners provided by GitLab or specific runners installed on dedicated machines, allowing parallel job execution.
13. What is GitLab Pages, and how can it be utilized?
GitLab Pages is a feature that allows users to publish static websites directly from a GitLab repository. It’s a simple way to host documentation, personal websites, or project pages.
14. Explain GitLab’s role in continuous integration.
GitLab’s CI/CD capabilities automate the continuous integration process by executing tests and builds whenever changes are pushed to the repository. This ensures code quality and identifies issues early in the development cycle.
15. How do you manage and resolve merge conflicts in GitLab?
To manage merge conflicts in GitLab, you need to manually resolve conflicting changes. This involves editing the conflicting files, committing the changes, and then completing the merge.
16. Discuss the significance of GitLab’s code review features.
GitLab’s code review features enable collaborative and constructive feedback on proposed changes. Developers can review code, leave comments, and suggest improvements before changes are merged.
17. Explain GitLab’s role in Docker container registry.
GitLab includes a container registry that can be used to store and manage Docker images. This allows developers to easily deploy and share containerized applications.

18. What is GitLab Omnibus?
GitLab Omnibus is a package that includes all the necessary components to run GitLab, including the GitLab application, database, and web server. It simplifies the installation process.
19. How do you integrate GitLab with Jira?
GitLab can be integrated with Jira by configuring the Jira integration settings in the GitLab project. This integration streamlines collaboration between developers and project management teams.
20. Discuss GitLab’s approach to version control branching strategies.
GitLab supports various branching strategies, including GitFlow and GitHub Flow. Developers can choose a strategy based on the project’s requirements, allowing flexibility in version control.
