GitLab Flow is applied in a real-world scenario for building a modular math library with proofs, numerical methods, and CI/CD integration.
The project involves creating features like Euler’s Method, Runge-Kutta 4th Order, and Analytical solutions, with CI tests for each algorithm.
Key steps include initializing the repository, creating feature branches, merge requests with code review, merging and CI validation, deploying to staging, and hotfix flow.
Important aspects highlighted are the use of feature branches, CI/CD pipelines, staging and production environments, merge requests, and the importance of squashing and rebasing for maintaining a readable Git history.
