YouTube Excerpt: *Git Masterclass: How Git Works in Production (Part 1)* 👉 GitHub Repository: https://github.com/CloudWithVarJosh/Git-Masterclass/tree/main/Part-1 👉 Git Playlist: 👉 Join the Channel to support: https://www.youtube.com/channel/UCaLKKEjj21ucnOYi45ZHwkw/join In this masterclass, we go beyond basic commands and build a deep understanding of how Git actually works under the hood. This is Part 1 of the Git Masterclass series, where we focus on core concepts, internal architecture, and the mental models required to use Git confidently in real-world environments. This is not just about learning commands. By the end of this session, you will not just use Git, you will understand how Git works. 🛠 *What You’ll Learn* * Why Git is critical in modern engineering (DevOps, IaC, GitOps) * Git architecture: working directory, staging area, local repository * What a commit really is (immutability, snapshots, history graph) * How .gitignore works and common pitfalls * Branching: concepts, pointers, and parallel development * Atomic development for clean commits and branches * Fast-forward and three-way merges * What actually happens during a merge * Merge conflicts: why they occur and how to resolve them * Renaming branches and default branch configuration * Undoing changes with git reset and git revert ⏰ Timestamps 00:00:00 Introduction 00:01:45 Why Git?
