Git & GitHub Fundamentals for DevOps

Be committed to learning when time provides, learning GIT, the backbone of software development and DevOps. I practiced setting up multiple accounts, generating SSH keys, creating repositories, staging & committing changes, and exploring the .git/ folder to understand Git’s internal structure. Documenting all commands in a file helped me organize my workflow and reinforce learning. 🔹 Key Takeaways Version Control: Track every change and collaborate efficiently Staging Area: Control what gets committed, don’t commit everything blindly SSH Keys & Security: Safely connect to remote repositories Commit Messages: Clear history for better team understanding Branches & Experimentation: Safely try new features without affecting main code Practicing Git hands-can help in improves coding discipline. #90DaysOfDevOps #Git #TrainWithShubham #GitHub #DevOpsJourney

Sharing my handwritten notes on Git & GitHub (Basic to Intermediate Level) 📘 While learning DevOps, I realized writing concepts by hand improves clarity and retention. So I documented everything — from git init to rebase, stash, and cherry-pick. This document covers: ✔ Git fundamentals ✔ Branching strategy ✔ Remote repository handling ✔ Rebase vs Merge ✔ Stash & Reset ✔ Cherry-pick & Squash Structured and curated by me during my DevOps journey. If you’re starting with Git or revising concepts, this might help you. #Git #GitHub #DevOps #VersionControl #LearningInPublic #CloudJourney #90DaysOfDevops #trainwithshubham #joshbatch10

📘 Day 31 — Git & GitHub 50 Commands Every Beginner Should Know (Final Post of My Git & GitHub Series) This is the last post in my Git & GitHub learning series. Not just a list of commands but a journey of understanding: • How changes are tracked • How teams collaborate • How mistakes are handled • How production is protected These 50 commands cover: 🔹 Daily Git usage 🔹 Branching and merging 🔹 Remote work with GitHub 🔹 Safe recovery from mistakes 🔹 Release and version control I didn’t learn Git to look smart with commands. I learned Git to work safely, clearly, and responsibly in real DevOps environments. This sheet is for: ✔ Beginners who feel confused ✔ Learners who want one clean reference ✔ Engineers who value safety over shortcuts This marks the end of my Git & GitHub phase and the beginning of applying it in real DevOps work. 📄 Image below 👇 🔑 Tools matter. Understanding matters more. #Day31 #Git #GitHub #DevOpsJourney #LearningInPublic #BuildInPublic #VersionControl #EngineeringMindset

Today I learned Git — and the most important shift for me was this: Git isn’t a tool. It’s a system of truth for change. What clicked: – Git tracks who changed what, where, and why – Commits aren’t backups; they’re decisions recorded in history – Collaboration works because everyone pulls from the same source of truth I spent time understanding: – staging vs committing – how git diff, status, and log help reason about change – why revert preserves history while reset rewrites it Also learned the difference between Git (the VCS) and platforms like GitHub, GitLab, Bitbucket that host repositories for distributed collaboration. I’ve written a clear beginner-friendly breakdown here: 👉 https://lnkd.in/gbD5B3nW Building fundamentals slowly, but with intent. #chaicode

🚀 Git Learning Journey – Day 3 Today’s task was all about forking repositories and collaborating the right way using Git. 🔹 Logged into a self-hosted Gitea server 🔹 Located an existing repository 🔹 Successfully forked the project under a new developer account 🔹 Understood how forking enables safe collaboration, experimentation, and independent development This exercise reinforced how teams work in real-world environments, especially in DevOps and open-source workflows, where contributors don’t push directly to the main repository but work from forks. Step by step, getting more comfortable with Git fundamentals and collaboration best practices 💪 #Git #DevOps #VersionControl #LearningInPublic #100DaysOfDevOps #GitWorkflow #SoftwareEngineering #kodekloud

Learning Git branching and tagging concepts today 💻 Explored two important Git features used in real projects: 🔹 Branch – used to work on new features or fixes without affecting the main code 🔹 Tag – used to mark specific versions or releases in a repository Commands I learned: 👉 git branch – list branches 👉 git branch feature-login – create a new branch 👉 git tag v1.0 – create a version tag Understanding these concepts helps in better code management 🚀 #Git #GitBranch #GitTag #VersionControl #DevOps

🚨“I did everything right… and Git still rejected my code.” git push -u origin master Git replied: ❌ non-fast-forward Code was right. Command was right. Confidence was high. Still… rejected. This is the part no tutorial warns you about. When: Repo is created on GitHub first Local repo is initialized separately 👉 Git sees two different histories 👉 And protects the remote branch This isn’t a beginner mistake. This is real-world Git — the kind you face in DevOps & CI/CD. 💡 Lesson learned: Git errors aren’t roadblocks. They’re lessons in collaboration. If Git ever made you doubt yourself — you’re learning the right way. 💬 Ever faced a Git error that made no sense at first? #Git #DevOps #LearningInPublic #CloudComputing #GitHub #DevOpsJourney #CareerSwitch

Git Stash & Git Cherry-Pick — Two Commands That Saved Me Multiple Times In real projects, Git problems look like this 👇 ❌ Urgent bug while mid-coding ❌ Committed to the wrong branch ❌ Don’t want messy merges That’s where: 👉 git stash 👉 git cherry-pick become absolute lifesavers. I wrote a problem-solving, beginner-friendly blog explaining: ✔ When to use git stash ✔ How cherry-pick avoids full merges ✔ Real-world DevOps scenarios ✔ Interview-ready understanding 📖 Read the full blog here: 👉 https://lnkd.in/gC5cd5ZV If you’re learning Git or preparing for DevOps roles — this will help you. #Git #DevOps #VersionControl #LearningInPublic #MediumBlog #DevOpsJourney

Day 6 – Git Advanced Today I completed Day 6: Git Advanced Concepts — understanding how real teams collaborate on projects. 🔹Pull Request (PR) A Pull Request is used to propose changes before merging code into the main branch. It allows: * Code review * Discussion * Approval before merging This is how professional teams maintain code quality. 🔹Rebase vs Merge Merge → Combines branches and keeps full history (creates a merge commit). Rebase → Moves your branch on top of another branch to keep history clean and linear. Both are useful depending on project needs. 🔹 Resolve Conflicts Conflicts happen when two people change the same part of a file. To resolve: 1. Identify conflict markers 2. Edit the file manually 3. Add and commit again Advanced Git knowledge is essential for working in real-world DevOps and team environments. #DevOps #Git #GitHub #VersionControl #LearningJourney #Day6
