Git Training — Version Control, Branching Strategies & Collaborative Development

What Is Git?

Git is the universal version control system — the foundation of modern software delivery. Every pull request, every CI/CD pipeline trigger, every Infrastructure as Code repository, and every GitOps workflow depends on Git. It's not just a tool you use; it's the control plane for how code, configuration, and infrastructure changes flow from idea to production. Understanding Git deeply — not just commit/push/pull — distinguishes engineers who ship from those who struggle with merge conflicts and lost work.

Role in Modern Software Delivery

Git is the entry point to every CI/CD pipeline. Your branching strategy determines your deployment cadence. Your commit hygiene determines your audit trail quality. Your merge strategy determines your release stability. In GitOps, Git IS the deployment mechanism — every merge to main triggers a production change. In DevSecOps, Git history provides the provenance trail for compliance. Git mastery is not optional.

Who Should Attend

• Software engineers at any level who want to move beyond basic Git
• DevOps engineers designing branching strategies and CI/CD integration
• Engineering managers setting team collaboration standards
• Anyone who has ever lost work to a bad merge

Learning Outcomes

• Master Git internals — objects, refs, DAG, the staging area, and how commits really work
• Execute complex branching, merging, and rebasing workflows with confidence
• Implement branching strategies — GitFlow, GitHub Flow, trunk-based development
• Write meaningful commit messages with Conventional Commits
• Use interactive rebase, cherry-pick, bisect, and reflog for advanced scenarios
• Integrate Git with CI/CD pipelines and GitOps workflows
• Implement Git hooks for automation and policy enforcement

Course Modules

1. Git Fundamentals — Repositories, commits, branches, the DAG. Staging area. How Git stores data internally.
2. Branching & Merging — Fast-forward vs. three-way merge. Merge commits. Conflict resolution strategies.
3. Rebasing — Interactive rebase. Squash, fixup, reword. When to rebase vs. merge. Golden rule of rebasing.
4. Branching Strategies — GitFlow. GitHub Flow. Trunk-based development. Choosing the right strategy for your team.
5. Advanced Git — Cherry-pick. Bisect. Reflog. Stash. Worktrees. Submodules vs. subtrees.
6. Commit Hygiene — Conventional Commits. Semantic versioning from commits. Changelog automation. Commit linting.
7. Git Hooks & Automation — pre-commit, commit-msg, pre-push hooks. Policy enforcement. Automated checks.
8. Git in CI/CD & GitOps — Pipeline triggers. PR-based workflows. Git as deployment source. GitOps with ArgoCD.

Resolve complex merge conflicts. Execute an interactive rebase to clean up a feature branch. Use git bisect to find a bug-introducing commit. Recover lost commits with reflog. Set up pre-commit hooks for linting. Configure a trunk-based CI/CD pipeline with PR triggers.

Enterprise Use Cases

• Standardizing trunk-based development across 200+ engineers with protected branches and CI/CD gates
• Implementing Conventional Commits for automated semantic versioning and changelog generation
• Using Git hooks for pre-commit secret scanning and code quality enforcement
