The most comprehensive Git learning experience for DevOps professionals
Welcome to the DevopsLab repository – a structured, multi-day hands-on simulation for mastering Git like a real DevOps engineer. This repo demonstrates core Git concepts across 5 progressive days of learning with actual project files, real branching logic, GitHub workflows, recovery commands, and team collaboration scenarios.
This isn't just another Git tutorial – it's a complete DevOps Git simulation that mirrors real-world scenarios:
- ✅ Real project structure - Not toy examples, but actual DevOps project layouts
- ✅ Interview-focused - Every scenario is something you'll face in DevOps interviews
- ✅ Progressive complexity - From basic branching to advanced Git hooks
- ✅ Practical challenges - Solve the same problems DevOps engineers face daily
- ✅ Documentation mindset - Learn to document like a professional

##💡 What Makes This Special?
- You'll practice scenarios like:
git checkout -b feature/user-authentication
git checkout -b hotfix/security-patch
git rebase -i HEAD~3
git cherry-pick abc123def
- "How do you resolve merge conflicts?" → Day 2 has you covered
- "Explain Git workflow in your team?" → Day 1 & 4 provide real examples
- "How to recover a deleted branch?" → Day 5 teaches git reflog
- "What are Git hooks?" → Day 5 includes practical implementations
Every challenge includes:
- Problem statement - What went wrong?
- Solution approach - How to fix it?
- Commands used - Exact Git commands
- Lessons learned - Key takeaways
