Mastering Git & GitHub for DevOps & SRE

Over the past few months, I’ve been mentoring a friend who’s just getting started in DevOps. During our self-development projects, I noticed something interesting: he kept saving small pieces of infrastructure and automation code as templates so he could reuse them in future projects. That stuck with me. In real-world DevOps, we rarely start from scratch. We reuse patterns — CI pipelines, Terraform modules, Kubernetes manifests, GitHub Actions, Helm charts, and more. So I decided to turn that idea into something bigger. 🚀 I’m creating an open-source DevOps code templates repository on GitHub A growing collection of reusable, production-inspired templates for common DevOps tools and workflows — built to help: Beginners learn faster Engineers avoid reinventing the wheel Teams bootstrap projects more efficiently The goal is simple: practical templates you can actually use, not just theory. I’ll keep improving it over time, and contributions, feedback, and suggestions are very welcome. Open source is how we grow — together. 💙 If you’re learning DevOps, mentoring someone, or just tired of starting from zero every time… this one’s for you. I will post the Github link as soon as i setup. #DevOps #OpenSource #CloudEngineering #InfrastructureAsCode #LearningInPublic #Mentorship #GitHub

Mastering Git Commands – The Backbone of Modern DevOps & Development!

"</> Git Walk through: Sophie joined a new team👩💻</>" 🚀 Every Developer, DevOps Engineer & IT Professional MUST Know Git! Whether you're writing code, deploying applications, managing infrastructure, or handling production releases — Git is not optional. It’s foundational. I’m starting a new post series to go deep into Git & GitHub, explained in a practical and relatable way. To make it interesting, I’ll introduce a character — 👩💻 Sophie — a developer who just joined a new team. Let’s begin her journey… 🌟 Day 1 – Sophie Joins a New Team Sophie has: ✅ Completed all prerequisites ✅ Finished mandatory trainings ✅ Got access to company systems Now she’s officially assigned to work on Production tasks. The first question she faces: 🤔 “Where do I start?” Since this is an existing application, she obviously needs the source code. So she reaches out to her supervisor and asks for: Repository details Required access/permissions Her supervisor shares a repository URL and says: 👉 “You’re good to go.” 📦 Step 1: Getting the Code Sophie runs a simple command: "git clone <repository-url>" ✨ And just like that… Git downloads: - The entire source code - Complete project history - Branch details - Commit records - Configuration - And creates a hidden .git folder 🧠 What is .git? Think of .git as: 🔥 The Brain of Git It contains: 📜 Full commit history 🔍 Tracking information ⚙️ Repository configuration 🌿 Branch references 🧩 Objects & metadata Without .git, your project is just files. With .git, your project has memory. Now Sophie has: 💻 A complete local working copy 📚 Full history 🔄 Version control enabled She’s ready to start contributing. 📌 In the next post, we’ll see: What happens before she starts coding? Should she directly commit to main branch? What are branches? How teams actually collaborate? Let’s continue Sophie’s journey tomorrow… If you're a: 👨💻 Developer ⚙️ DevOps Engineer ☁️ Cloud Engineer 🛠️ SRE 🎓 Student entering IT This series will help you understand Git the right way — practically.

🚀 DevOps Interview Questions & Answers 📌 Question: What is Git Rebase? Git Rebase is used to move or combine a sequence of commits onto a new base commit. 🔹 It takes commits from one branch 🔹 Re-applies them on top of another branch 🔹 Creates a clean and linear project history 🔹 Avoids unnecessary merge commits 📌 Why use Rebase? ✔ Keeps commit history clean ✔ Makes project history easier to read ✔ Helps maintain a linear workflow 📌 Basic Command: git rebase main 📌 Interactive Rebase (to edit/squash commits): git rebase -i HEAD~3 💡 Important: Avoid rebasing public/shared branches because it rewrites commit history. 👉 Follow Ashok IT School for daily DevOps interview questions 👉 Comment “DEVOPS” for real-time Git & Cloud concepts 👉For DevOps Course Details  Visit:https://lnkd.in/ggFkVtT4 . #DevOps #Git #GitRebase #VersionControl #GitCommands #CI_CD #SoftwareDevelopment #CloudComputing #AshokIT #AshokITSchool

GitHub and Its Role in Devops GitHub is a cloud platform where we store and manage code online. Think of it like Google Drive for code — but with version control, tracking, and team collaboration. How is GitHub Used? Write code on your system → Initialize Git →Connect to a GitHub repository → Push code to GitHub → Team members pull & collaborate Git Push vs Git Pull - git push → Upload your local code to GitHub - git pull → Download latest code from GitHub - Push = Send code - Pull = Get code What are Branches? A branch is a separate copy of code where we can work safely without affecting the main project. Used for: New features, Bug fixes, Testing Create branch → Work → Push → Pull Request → Merge Main vs Master Both are primary branches. • Master → Old default branch name • Main → New default branch name No technical difference — both store final production code. #Git #GitHub #DevOps #VersionControl #SoftwareDevelopment #CloudComputing #CICD #BeginnerFriendly #TechLearning #Developers

🚀 Day 50 of my Learning Journey – Git Workflow 💻📘 Discovered how real-world developers manage and collaborate on code using Git and GitHub. Learning the Git workflow unlocked a clearer understanding of how projects move from local development to production-ready code. 📘 What is Git Workflow? Git workflow is the structured process of tracking, saving, sharing, and updating code using Git and GitHub. It helps developers manage changes, collaborate efficiently, and maintain clean project history. From startups to large tech companies, Git workflows are used daily to manage software development and DevOps pipelines. 💻 Key Commands & Concepts I Learned 🔹git add . – Stages all modified files to prepare them for commit. 🔹git commit -m "message" – Saves changes locally with a meaningful message. 🔹git push – Uploads local commits to the remote GitHub repository. 🔹git pull – Fetches and merges latest changes from the remote repository. 🔹git fetch – Downloads updates from remote without merging. 🔹git merge – Combines changes from different branches into one. 🎯 Key Takeaway I understood that Git is not just about commands — it's about maintaining structured collaboration and clean version history, which is essential for my DevOps and Cloud career. ⚙️ Real-World & Industry Usage 🔹Production Servers – Teams push stable code to repositories before deployment. 🔹Cloud Infrastructure – Infrastructure as Code (IaC) files are version-controlled using Git. 🔹CI/CD Pipelines – Tools like Jenkins and GitHub Actions trigger builds automatically on git push. 🔹Team Collaboration – Multiple developers work on branches and merge changes safely. 🔹Monitoring & Rollback – Git history allows quick rollback if a deployment fails. Every day, I’m getting closer to becoming a confident DevOps & Cloud Engineer 📈 #Git #GitHub #DevOpsJourney #LearnInPublic #CloudComputing #SoftwareDevelopment #CareerGrowth
