DevOps Bootcamp Week 3: Git Challenges and Fundamentals

🚀 Day 3 – Git Learning Journey | Revert & Branching Continuing my DevOps journey, today I explored two important Git concepts used in real-time development and collaboration. 🔹 Key Concepts Covered: 🔁 Git Revert Used to undo changes by creating a new commit ✔️ Safe way to reverse changes without losing history ✔️ Best used in shared/public branches 👉 Example: git revert <commit-id> 🌿 Git Branch Branches allow parallel development without affecting the main code ✔️ Create branch → git branch feature ✔️ Switch branch → git checkout feature ✔️ Create & switch → git checkout -b feature 💡 Helps developers work independently and merge later 📊 Simple Visualization: Main Branch: A —— B —— C Feature Branch: ↳ D —— E 👉 Work happens in feature branch, then merged to main 💡 Interview Insights: Difference between git reset vs git revert What is branching in Git? Why do we use branches? How to switch branches? 🔥 Learning step by step — building strong Git fundamentals for DevOps & Cloud. #Git #DevOps #AWS #LearningJourney #VersionControl #CloudComputing #CareerGrowth #FLM #frontlinesmedia

🚀 Day 12 – DevOps Learning Missed today’s session, but stayed consistent by revising Git & GitHub fundamentals 💻 🔹 Quick Refresher: ✔ Git – Version control system to track code locally ✔ GitHub – Cloud platform to store and collaborate on code 🔹 What I Practiced: Managing code with git add, commit, push, pull Understanding how local code connects to remote repositories Organizing projects and improving workflow 🔹 Key Learning: Git helps me manage code efficiently, while GitHub helps me showcase and collaborate with others. Consistency matters more than perfection. Showing up every day 📈 #DevOps #Git #GitHub #LearningJourney #Day12 #100DaysOfDevOps #CareerGrowth #VersionControl

💻 Getting Started with GitHub – My Learning Today Today I explored GitHub and understood how powerful it is for developers and DevOps engineers. GitHub is a platform built on Git that helps in version control, collaboration, and managing code efficiently. It’s widely used across the industry to host repositories and work together on projects. 🔹 Key Things I Learned: ✅ Repositories (Repos) A repository is where your project code lives. It keeps track of all changes and versions. ✅ Version Control with Git Every change is tracked using commits, making it easy to go back to previous versions if needed. ✅ Branches Branches allow you to work on new features or fixes without affecting the main code. ✅ Pull Requests (PRs) Pull requests help in reviewing and merging code changes collaboratively. ✅ Collaboration Made Easy Multiple developers can work on the same project, review each other’s code, and maintain quality. ✅ Open Source Contribution GitHub enables developers to contribute to open-source projects and learn from real-world code. 💡 My Takeaway: GitHub is not just a code storage platform—it’s a complete ecosystem for collaboration, learning, and building scalable applications. Excited to apply this knowledge in real projects and explore more advanced features soon! 🚀 #GitHub #DevOps #CloudEngineering #LearningJourney #VersionControl #Azure #TechGrowth

🚀 DevOps Learning: Jenkins Shared Library & Git Rebase vs Merge Sharing some key concepts I’ve been learning and practicing 👇 🔹 Jenkins Shared Library A Jenkins Shared Library is a reusable collection of Groovy scripts stored in a Git repository, used to standardize and simplify pipeline code across multiple Jenkins jobs. ✔️ Promotes code reusability ✔️ Reduces duplication ✔️ Ensures consistent CI/CD pipelines 🔹 Git Merge vs Rebase ✅ Merge Combines two branches Keeps full history (creates a merge commit) Non-linear history 👉 Use when: Working in teams and preserving history git checkout main git merge feature-branch ✅ Rebase Moves your branch on top of another branch Rewrites commit history Linear, clean history 👉 Use when: Cleaning up local commits git checkout feature-branch git rebase main git checkout main git merge feature-branch 💡 Key Takeaway: Use merge for shared branches and rebase for local branches to maintain a clean and manageable Git history.

🔥 Git & GitHub — Every DevOps Engineer's Best Friend! Today I learned Git from scratch and pushed my FIRST code to GitHub! 🎊 Here's what I learned: Git = Version control tool GitHub = Cloud for your code Like Microsoft Word's "Track Changes" but 1000x more powerful! 💪 CORE WORKFLOW: git init → Start tracking a project! git status → Most used command! → See what changed! git add . → Stage all changes! git commit -m "message" → Save a snapshot! 📸 → Like a checkpoint in a video game! 🎮 git push → Upload to GitHub! ☁️ BRANCHES — Mind blowing! 🤯 git branch feature-login → Create parallel universe! git checkout feature-login → Switch to it! Work safely without breaking main code! git merge feature-login → Combine when done! ✅ 🌟 Most amazing part: Same folder! Different files! Based on which branch you are on! 🌌 Master branch = no login page Feature branch = has login page Switch branch = files appear/disappear! 🔥 Just pushed my first repo to GitHub! 🎊 Check it out: https://lnkd.in/gf8UKsHP #Git #GitHub #DevOps #AWS #LearningInPublic #CloudComputing #Fresher #TechJourney #DevOpsEngineer #VersionControl #Coding

🚀 Day 3 of My DevOps Journey — Docker (Where Things Got Real) After Linux and Git, today I stepped into Docker — and this is where everything started to feel like real DevOps. 🔹 What I Practiced: 👉 Running containers using docker run 👉 Understanding images vs containers 👉 Port mapping (-p 8080:80) 👉 Naming containers 👉 Viewing logs using docker logs 👉 Inspecting containers (docker inspect) 🔹 Mini Project: I deployed an NGINX container locally: ✔ Pulled image from Docker Hub ✔ Ran container on custom port ✔ Verified using browser & curl ✔ Checked logs and container status 🔹 Real Issue I Faced: ❌ “Port already allocated” error This happened because: Another container was already using the same port. 🔹 How I Fixed It: ✔ Identified running containers (docker ps) ✔ Stopped conflicting container ✔ Re-ran with a different port 💡 Key Learning: “Docker is not just about running containers — it’s about managing environments.” Now I understand: ➡️ Why containers are lightweight ➡️ How DevOps teams ensure consistency across environments ➡️ Why Docker is used in CI/CD pipelines Next → Building custom images using Dockerfile 🔥 If you’re learning Docker or struggled with it, let’s connect 🤝 #DevOps #Docker #Containers #Cloud #AWS #LearningInPublic #BuildInPublic #CI_CD

📘 #100DaysOfDevOps – Day 10 (GitHub – Day 1) Today I started learning Git & GitHub 🚀 GitHub is a platform used to store code, track changes, and collaborate with others. It is one of the most important tools for developers and DevOps engineers. --- 🔹 What I Learned Today 👉 What is Git? Git is a version control system used to track changes in code. 👉 What is GitHub? GitHub is a cloud platform to host and manage Git repositories. --- 🔹 Basic Commands I Practiced Initialize repository "git init" Check status "git status" Add files "git add ." Commit changes "git commit -m "First commit"" Connect to GitHub "git remote add origin <repo_url>" Push code "git push -u origin main" --- 🔹 Key Concepts • Repository (repo) • Commit (save changes) • Version control • Local vs Remote repo --- 💡 Key Learning: Git and GitHub help in tracking changes, collaboration, and managing code efficiently, which is essential in DevOps workflows.
