GitLab for Everyone: Your First CI/CD Pipeline Explained

Description

Stop fighting with broken deployments and start automating! In this beginner-friendly tutorial, Colleen Lake, Developer Advocate at GitLab, breaks down the fundamentals of CI/CD. Whether you're a seasoned dev who’s avoided DevOps or a complete beginner, this video will help you build a pipeline that tests, builds, and deploys your code automatically. We’ll walk through setting up a .gitlab-ci.yml file from scratch, using a real React game as our project. You'll learn how to catch bugs before they go live and how to ensure your code is production-ready every single time. What You’ll Learn: * The "Magic" of CI/CD: How to automate the boring stuff and save hours of manual work. * Pipeline Structure: Understanding Stages (Test, Build, Deploy) and how they protect your production environment. * Artifacts & Caching: How to pass files between jobs and speed up your workflow. * Troubleshooting: Where to look when things go wrong (Hint: Always read the logs!).
