#Day_13 – Starting Git, GitHub & GitLab (DevOps Journey) Today, I started learning Git, GitHub, and GitLab, and this is one of the most important steps in my DevOps journey. 👉 Version control is not optional… it is a must for every developer and DevOps engineer. 🔹 What is Git? (Basic Understanding) Git is a version control system that helps track changes in code. Keeps a history of all changes Helps in teamwork Easy to go back to previous versions 👉 It is like a “save + history + backup system” for code. 🔹 Basic Git Commands git init – start a new repository git status – check current state git add . – add files to staging git commit -m "message" – save changes git log – see commit history 👉 These are the most used daily commands. 🔹 What is GitHub? GitHub is a cloud platform where we store our Git repositories. Store code online Share projects Collaborate with others 👉 It is widely used in industry. 🔹 What is GitLab? GitLab is similar to GitHub but also provides: Built-in CI/CD More control for DevOps Used in many companies 👉 Both GitHub and GitLab are important tools. 🔹 Working with Remote Repositories git remote add origin <url> git push – upload code git pull – get the latest code 👉 Helps in teamwork and syncing code. 🔹 Branching Concept git branch – create branch git checkout – switch branch git merge – merge changes 👉 Branching helps work on features without affecting the main code. 🔹 Collaboration Basics Multiple people work on the same project Use pull requests/merge requests Review code before merging 👉 This is how real companies work. 🔹 Why Git is Important in DevOps? Track every change Easy rollback Supports CI/CD pipelines Helps automation 👉 Without Git, DevOps is incomplete. What I realised today: ✔ Git is the backbone of development ✔ GitHub/GitLab make collaboration easy ✔ Version control is a must-have skill ✔ Every DevOps engineer uses Git daily 👉 Today was very important for my journey.

#Day_14 – Advanced Git, GitHub & GitLab Today, I moved ahead with Advanced Git, GitHub, and GitLab, and now I can see how real teams manage code in production. 👉 Git is not just saving code… it is about managing code smartly in teams. 🔹 Git Branching Strategy (Advanced) main / master – production code develop – ongoing development Feature branches – for new features Hotfix branches – for urgent fixes 👉 This helps teams work without breaking main code. 🔹 Advanced Git Commands git clone <url> – copy repo git fetch – get latest changes (without merging) git pull – fetch + merge git stash – save temporary changes git reset – undo changes git revert – safe undo 👉 These commands are used in real-world workflows. 🔹 Merge vs Rebase Merge – keeps full history Rebase – makes clean history 👉 Rebase is useful for clean projects, but needs careful use. 🔹 Conflict Resolution Happens when same file is edited by multiple people Git shows conflict markers Manually fix and commit again 👉 Important skill for teamwork. 🔹 GitHub Advanced Features Pull Requests (PR) Code Reviews Issues & Project boards GitHub Actions (CI/CD basics) 👉 Helps in managing complete development lifecycle. 🔹 GitLab Advanced Features Merge Requests Built-in CI/CD pipelines Runners for automation DevOps lifecycle in one platform 👉 GitLab is powerful for DevOps automation. 🔹 .gitignore & Best Practices Ignore unwanted files (node_modules, logs) Keep repo clean Write meaningful commit messages 👉 Clean code = professional work. 🔹 Tags & Versioning git tag – mark versions (v1.0, v2.0) Helps in releases Easy to track versions 👉 Important for production deployments. 🔹 Why Advanced Git is Important? Handle large projects Work in teams Maintain clean history Support CI/CD pipelines 👉 This is how companies manage real projects. What I realized today: ✔ Git is more powerful than I thought ✔ Team collaboration depends on proper workflow ✔ Clean history and versioning are very important ✔ GitHub/GitLab are full DevOps platforms Learning is now moving towards real industry practices 🚀 Let’s keep learning and growing 💪 #Linux #DevOps #Git #GitHub #GitLab #Day14 #LearningInPublic #ITSkills #CareerGrowth

🚀 DevOps Journey – Day 19 / 100 Today I learned Git Tags, Fork, Merge Conflicts & Bitbucket 🔥 ⸻ 🔹 🏷️ Git Tags (Versioning) 👉 Tags are like milestones / backups in Git 📌 Example: Version1 → 3 commits Version2 → 2 more commits Version3 → 2 more commits 👉 We can mark versions like: • app-v1 • app-v2 • app-v3 ⸻ 🔹 🧪 Hands-on Example mkdir project cd project git init touch file1 file2 file3 git add file1 git commit -m "file1 commit" git add file2 git commit -m "file2 commit" git add file3 git commit -m "file3 commit" 👉 Apply tags: git tag app-v1 git tag git log 👉 Push tag to GitHub: git push origin app-v1 git push origin --tags 🔹 🍴 Git Fork 👉 Fork = Copy of someone else’s repo into your GitHub 📌 Steps: 1. Click Fork in GitHub 2. Repo copied to your account 3. Clone → Make changes → Push 💡 Used in open source contributions ⸻ 🔹 ⚠️ Merge Conflicts (Real-Time) 👉 When 2 people change same file/line → Conflict 🎬 Example: Tillu & Shanon both ask Radhika for movie at 1:30 PM 😅 👉 Same time → Conflict 💡 Solution: • Manually edit file • Remove conflict markers • Commit resolved code ⸻ 🔹 🔁 Git Alternatives • Bitbucket • Azure Repos • AWS CodeCommit ⸻ 🔹 🔵 Bitbucket Basics 👉 Same as GitHub (Repo hosting) 📌 Workflow: • Create repo • Clone repo • Create branch • Commit changes • Push & Pull ⸻ 🔹 🔐 Bitbucket Token (App Password) 📌 Steps: • Go to Settings → Access Management • Create App Password / API Token • Set permissions (read/write) • Use instead of password ⸻ 💡 Pro Tip: Use tags for releases, forks for contributions, and always resolve conflicts carefully!

🚀 DevOps Study Update – Git & GitHub Fundamentals Today I focused on strengthening my understanding of version control with Git and collaboration using GitHub. Here’s a quick breakdown of what I covered: 🔹 Git Repository A repository (repo) is where your project lives. It tracks all changes, history, and versions of your files—locally or remotely. 🔹 GitHub A cloud-based platform that hosts Git repositories. It enables collaboration, version tracking, and code sharing with teams worldwide. 🔹 git clone Used to copy a remote repository (from GitHub) to your local machine: git clone <repo-url> 🔹 git push Uploads your local commits to a remote repository: git push origin <branch> 🔹 git pull Fetches and integrates changes from a remote repository into your local branch: git pull origin <branch> 🔹 git merge Combines changes from one branch into another. Commonly used to integrate feature branches into main branches. 💡 Key Takeaway: Git helps manage code history efficiently, while GitHub enhances collaboration and project visibility—both are essential skills for any DevOps engineer. #DevOps #Git #GitHub #CloudComputing #LearningJourney #VersionControl :::

🚀 Leveling Up My Git Game: Beyond the Basics After getting comfortable with Git fundamentals, I decided to go deeper and that’s where things started getting really interesting. This phase wasn’t just about commands… it was about understanding how real-world DevOps teams manage code, avoid conflicts, and ship faster. --> Here’s what I explored: - Git Merge vs Rebase Understanding the difference changed how I think about commit history. * git merge → Keeps history intact (safe & simple) * git rebase → Cleaner, linear history (but needs caution) -  Git Cherry-Pick One of the most practical features I learned! * Apply a specific commit from one branch to another * Super useful when you need a quick fix without merging everything * Helps in hotfix scenarios and selective deployments - Git Fork Learning how open-source collaboration works. Forking repositories, making changes, and contributing back via pull requests — just like real-world distributed teams. - Git Stash A lifesaver during context switching. Quickly saving uncommitted work and coming back later without losing progress. - .gitignore Small file, big impact. Preventing unnecessary files (logs, env files, build artifacts) from polluting the repo. - GitHub Pages Deployed a simple static site directly from a repo Understanding how code can go live without complex infrastructure was eye-opening. --> Key Takeaway: Git is not just a tool it’s a collaboration strategy. From handling merge conflicts to maintaining a clean commit history, these concepts are exactly what DevOps and Cloud workflows rely on. -> What’s Next? Integrating these workflows into CI/CD pipelines and automating deployments. #DevOps #Git #GitHub #VersionControl #Cloud #OpenSource #LearningInPublic #CICD #TechJourney
