Git & GitHub for DevOps Students in Bangalore

Introduction

Every modern DevOps pipeline starts with code. Git tracks every change. GitHub hosts, reviews, and automates it. In Bangalore’s fast-moving tech hubs, companies expect you to commit clean code, review pull requests, and trigger builds automatically.

This guide is for DevOps students in Bangalore. You will learn Git from basics to advanced workflows. We cover commands, strategies, GitOps, and real-world collaboration. By the end, you will manage code like a pro and impress in interviews.

Getting Started with Git: Setup and First Commit

Git is a distributed version control system. Install it and configure your identity.

• Download from git-scm.com
• Run: git config --global user.name "Your Name"
• Run: git config --global user.email "[email protected]"

Create your first repo:

• mkdir my-project && cd my-project
• git init
• echo "# Hello" > README.md
• git add . && git commit -m "Initial commit"

At DevOps Training Institute, every student starts with a personal repo on day one. You push to GitHub and set up SSH keys for, GPG signing, and .gitignore.

Essential Git Commands Every DevOps Engineer Must Know

Master these 20 commands to survive in production.

Practice daily. DevOps Training Institute runs Git labs where you break and fix repos on purpose.

Git Branching Strategies for DevOps Teams

Use the right model to avoid chaos.

Git Flow

Classic for release cycles.

• main: production
• develop: integration
• feature/*: new work
• release/*: prep for deploy
• hotfix/*: urgent fixes

Trunk-Based Development

Elite teams deploy from main daily.

• Short-lived feature branches (<1 day)
• Feature flags for incomplete work
• CI runs on every commit

GitHub Collaboration Workflow

Real teams use pull requests, not direct pushes.

Step-by-Step PR Process

• Fork or branch from main
• Commit small, logical changes
• Push and open PR
• Add reviewers and labels
• Run CI checks (lint, test, build)
• Address feedback with new commits
• Squash and merge when approved

DevOps Training Institute simulates enterprise PRs with code owners, required checks, and auto-deploy on merge.

GitHub Features for DevOps

• Protected branches: require PR and status checks
• CODEOWNERS file: auto-assign reviewers
• GitHub Actions: CI/CD in YAML
• Projects: Kanban for issues
• Security: Dependabot alerts

GitOps: Managing Infrastructure with Git

Git becomes the single source of truth for apps and infra.

• Declarative YAML in repo
• ArgoCD or Flux syncs cluster state
• PR to change environment
• Audit trail of every deploy

Students deploy a full app using GitOps in week 6. You learn drift detection and rollback via Git revert.

Explore environment parity using GitOps to keep dev, staging, and prod identical.

Advanced Git: Solving Real-World Problems

Handle conflicts, large files, and history rewrites.

Merge Conflicts

• Always pull before push
• Use git merge --abort to reset
• Resolve in editor, then git add and commit

Large File Storage

Use Git LFS for binaries, Docker images, or models.

• git lfs install
• git lfs track "*.zip"
• Commit and push as usual

Cleaning History

• git rebase -i HEAD~5: squash or edit commits
• git push --force-with-lease: safe force push

Git Hooks and Automation

Enforce standards automatically.

Client-Side Hooks

• pre-commit: run linter, tests
• commit-msg: enforce message format

Server-Side Hooks

• pre-receive: block large pushes
• post-receive: trigger Jenkins build

DevOps Training Institute provides pre-built hook templates. You deploy them in GitHub Actions and self-hosted runners.

GitHub Actions: CI/CD in Your Repo

Write workflows in .github/workflows/.

• Build Docker image
• Run tests in parallel
• Scan with Trivy
• Deploy to Kubernetes

Every student builds a complete pipeline: commit → test → build → scan → deploy. No external CI tool needed.

Secure your images with container scanning in GitHub Actions.

Conclusion: Git Is Your DevOps Superpower

Git and GitHub are not optional. They are the foundation of modern software delivery. In Bangalore, every DevOps role lists Git proficiency. Master branching, PRs, GitOps, and automation to stand out.

Frequently Asked Questions

Do I need GitHub Pro?

No. Free tier works. Enterprise features taught via institute accounts.

Is Git same as GitHub?

No. Git is the tool. GitHub is the platform. You use both daily.

Can I learn Git without coding?

Yes. Focus on ops workflows. Basic scripting helps later.

What if I delete a branch?

Recover with git reflog. Always backup before force operations.

Is rebase dangerous?

Only on shared branches. Rebase feature branches. Merge main.

Do you teach GitLab or Bitbucket?

Core Git is same. GitHub focus. Concepts transfer easily.

How many PRs will I create?

20+ during training. From bug fixes to new features.

Can I use Git in interviews?

Yes. Explain your workflow. Share GitHub profile. Impress with clean history.

Is GitOps mandatory?

Growing fast. Kubernetes roles require it. You learn ArgoCD hands-on.

What about monorepos?

Covered. Use Nx or Lerna. Scale Git for large codebases.

Do you cover Git security?

Yes. Signed commits, branch protection, secret scanning.

Can I contribute to open source?

Yes. Institute guides your first PR to a real project.

Is training online or offline?

Both. Weekend offline in Marathahalli. Weekday online live.

How long is the Git module?

2 full weeks. Then used in every project thereafter.

Will I get a certificate?

Yes. Git & GitHub Mastery with project links.
