Sometimes life pauses your plans. But it doesn’t cancel your goals. After a short gap, I’ve restarted my journey toward becoming a DevOps Engineer. I Completed Git fundamentals and strengthened my understanding of version control, branching strategies, and collaboration workflows. From Service Management to DevOps — building my skills step by step. Consistency > Motivation. #DevOps #Git #DevOpsJourney #CareerGrowth #Learning 🚀 Git Commands I Learned (DevOps Journey) Here are the Git concepts I’ve learned and practiced: 🔹 git init - Initializes a new Git repository in your project folder. 🔹 git add - Moves files from Working Directory to the Staging Area. 🔹 git commit - Saves the staged changes into the Local Repository with a message. 🔹 git push - Uploads local commits to the Remote Repository (like GitHub). 🔹 git status - Shows the current state of files (modified, staged, untracked). 🔹 git log - Displays the commit history. 🔹 git merge - Combines changes from one branch into another branch. 🔹 git rebase - Moves or reapplies commits on top of another branch to maintain a clean history. 🔹 git cherry-pick - Applies a specific commit from one branch to another branch. 🔹 git config - Sets configuration details like username and email. 🔹 git diff - Shows the differences between file versions or commits. 🔹 git branch- Creates or lists branches. 🔹 git checkout- Switches between branches (or restores files). 🔹 git fetch - Downloads updates from the remote repository but does not merge them. 🔹 git pull - Fetches and merges the latest changes from the remote repository. 🔹 git clone - Creates a copy of a remote repository on your local machine. 🔹 git revert - Creates a new commit that undoes changes from a previous commit. 🔹 git reset - Moves the branch pointer to a previous commit (can remove commits depending on the mode used). 🔹 git reflog - Shows the history of all actions performed in Git (useful to recover deleted commits). 🔹 git tag - Adds a version label to a specific commit (like v1.0). 🔹 git stash - Temporarily saves uncommitted changes so you can switch branches safely. 🔹 git squash - Combines multiple commits into a single commit (usually done during rebase).

🚀 Day 24 – Advanced Git: Merge vs Rebase vs Stash vs Cherry-Pick Today I moved beyond basic Git usage and stepped into real-world workflows. This is where Git stops being “just version control” and starts becoming a collaboration power tool. 🔀 1️⃣ Merge vs Fast-Forward vs Merge Commit I practiced: ✅ Fast-forward merge ✅ Merge commit (non-linear history) ✅ Creating intentional merge conflicts 💡 Realization: If main hasn’t moved → Git does a fast-forward If both branches have new commits → Git creates a merge commit If the same line is edited → 💥 Merge conflict Seeing git log --oneline --graph --all changed everything. History tells the full story. 🔁 2️⃣ Rebase – Clean History Mode Rebase rewrites commit history by replaying commits on top of another branch. 📌 Merge → Branching history 📌 Rebase → Linear history ⚠️ Important Rule: Never rebase commits that are already pushed and shared. Because rebase changes commit hashes → and breaks collaboration. 🧳 3️⃣ Git Stash – Context Switching Like a Pro Started working → urgent task came → didn’t want to commit messy code. Used: git stash git stash pop Saved work instantly without committing. This is how professionals handle interruptions. 🎯 4️⃣ Cherry Pick – Surgical Commit Transfer Needed only one commit from a feature branch. Used: git cherry-pick <commit-hash> Only that specific change was applied. Powerful for: ✔ Hotfixes ✔ Production patches ✔ Backporting fixes 🧠 Biggest Learning Today Git isn’t about commands. It’s about history control. ✔ Merge → Collaboration ✔ Rebase → Clean history ✔ Stash → Flexibility ✔ Cherry-pick → Precision Now I understand how real DevOps teams manage code safely. Small steps. Strong foundations. 💪 #90DaysOfDevOps #DevOpsKaJosh #TrainWithShubham #Git #DevOpsJourney #VersionControl #LearningInPublic

Git Tagging – marking important moments in code 🏷️ Think of Git like a timeline of your project. A Git tag is a label you attach to a specific point in that timeline. 🔹 What is Git Tagging? Git tagging is used to mark important versions of your code—like releases, milestones, or hotfix points. 🔹 Why use tags? ✔ Identify production releases ✔ Easy rollback to a stable version ✔ Clear version history ✔ Better collaboration across teams 🔹 Common use cases: 🏷️ v1.0.0 – First production release 🏷️ v1.1.0 – New feature release 🏷️ v1.0.1 – Bug fix / hotfix 🔹 Tags vs Branches (quick difference): Branch → keeps moving (ongoing work) Tag → stays fixed (snapshot in time) 👉 Tags act like checkpoints you can always trust. In CI/CD pipelines, tags often trigger release builds and deployments, making them a key part of modern DevOps. #Git #GitTagging #VersionControl #DevOps #SoftwareEngineering #Agile

🚀 Day 22 – My First Git Repository Created! Today I officially started my Git journey 🔥 Git is the backbone of DevOps — every CI/CD pipeline, collaboration workflow, and automation process depends on version control. So today was all about getting comfortable with the fundamentals. 📌 What I Did Today ✅ Installed & configured Git (set up name & email) ✅ Created my first repository: devops-git-practice ✅ Explored the hidden .git/ directory ✅ Created a living reference file: git-commands.md ✅ Made multiple commits with meaningful messages ✅ Built a clean commit history ✅ Understood working directory, staging area & repository 💡 Key Learnings 🔹 git add → Moves changes to the staging area 🔹 git commit → Saves staged changes permanently 🔹 git status → My new best friend 👀 🔹 git log --oneline → Clean way to view commit history 🔹 The .git/ folder → The heart of the repository (delete it and version control is gone!) Understanding the difference between: Working Directory Staging Area Repository …made Git workflow much clearer. 🧠 Biggest Realization Git doesn’t just save files. It saves history. And history = accountability + collaboration + confidence. Small steps, strong foundations 💪 This is just the beginning. Tomorrow we go deeper. #90DaysOfDevOps #DevOpsKaJosh #TrainWithShubham #Git #VersionControl #DevOpsJourney

🚀 The Complete Git & GitHub Workflow Every Developer Should Master (From your local machine to production — without losing control of your code) Git is not just about commit and push. It’s about control, collaboration, traceability, and security in development. When you truly understand the workflow, your level as an engineer changes completely. Here’s the complete flow explained in a simple and practical way 👇 1️⃣ Working Directory — Where Everything Begins This is where you write code, create files, and make real changes. Key command: git init → Initialize a repository. Everything starts here. 2️⃣ Staging Area — Preparing the Commit Here you decide exactly which changes will be recorded. Key command: git add . → Send changes to staging. This is precise version control. 3️⃣ Local Repository — Your Project’s History You save snapshots of your project through commits. Key command: git commit -m "message" This becomes your project’s timeline. 4️⃣ Branching — Develop Without Breaking Production Work on features independently without affecting main. Key commands: git branch feature-x git checkout feature-x This enables real parallel development. 5️⃣ Merge — Integrating Changes Combine branches once a feature is ready. Key command: git merge feature-x This is where conflicts either appear… or get resolved. 6️⃣ Remote Repository — Global Collaboration Your code lives on platforms like GitHub, GitLab, or Bitbucket. Key command: git push origin main This keeps your team synchronized. 7️⃣ Fetch vs Pull — Know the Difference git fetch → Retrieves changes without merging. git pull → Retrieves and merges automatically. Pull = Fetch + Merge. Understanding this prevents mistakes. 8️⃣ Pull Request — Quality Control Layer Before merging to main: • Code review • CI/CD checks • Validation • Team discussion This is where software quality is protected. 9️⃣ The Professional Workflow (What Senior Teams Actually Use) git checkout -b feature Code + small commits git push origin feature Pull Request + CI/CD Code Review Merge to main Deploy 🚀 Advanced Git Mindset • Small commits > massive commits • One branch per feature • Never work directly on main • Pull before you push • CI/CD is your quality guardian Which workflow does your team use? 🌿 Git Flow 🚀 Trunk-Based Development ⚡ GitHub Flow 🔧 Custom Strategy Let’s discuss 👇 #Git #GitHub #VersionControl #SoftwareEngineering #DevOps #CICD #Programming #EngineeringWorkflow

Revising Git Commands – Strengthening My DevOps Foundation In DevOps, Git is not just a version control tool — it’s the backbone of CI/CD, automation, and collaboration. Today, I revised all the core commands from my Git cheat sheet to reinforce my DevOps fundamentals. 🔁 Here’s what I focused on: 🔹 git init – Repository setup 🔹 git clone – Environment setup from remote 🔹 git branch – Feature & release strategy 🔹 git checkout / git switch – Branch navigation 🔹 git merge – Integration workflows 🔹 git rebase – Clean commit history 🔹 git pull – Syncing with remote 🔹 git push – Triggering CI pipelines 🔹 git stash – Handling hotfix interruptions 🔹 git reset / git revert – Safe rollback strategies In a DevOps pipeline: ✅ Every push can trigger automated builds ✅ Every merge can deploy to staging ✅ Every rollback can save production Understanding Git deeply means: ✔️ Fewer merge conflicts ✔️ Cleaner pipelines ✔️ Better collaboration ✔️ Faster deployments DevOps isn’t just about tools like Docker, Jenkins, or Kubernetes. It starts with mastering Git. Strong Git knowledge = Strong CI/CD foundation. #DevOps #Git #CI_CD #Automation #Cloud #LearningJourney #SoftwareEngineering

🚀 DevOps Basics Series When I first learned Git, I just memorized commands: git add git commit git push git pull But I didn’t really understand what they meant. Once I understood the flow, everything clicked. Here’s the simple version: 🔹 git add → Select the changes you want to track. 🔹 git commit → Save a snapshot of those changes. 🔹 git push → Send them to the remote repository. 🔹 git pull → Get the latest updates from others. That’s it. Modify → Add → Commit → Push → Repeat. And here’s where it gets interesting in DevOps: That one git push can trigger: ✔ Automated tests ✔ Builds ✔ Deployments One command → Entire pipeline starts. Understanding this made Git feel less like commands… and more like a system. #DevOps #Git #LearningInPublic #CI_CD

Today was all about understanding Git deeply — not just commands, but the logic behind version control. 🔹 What I Learned ✅ What Version Control actually means → Tracking every change in code → Ability to revert to previous versions → Safe collaboration without overwriting others’ work ✅ Core Git Commands: git init git clone git status git add git commit git log ✅ Branching Concept I finally understood why branches are powerful. Feature branches allow safe experimentation without affecting the main codebase. ✅ Merge vs Rebase Merge keeps history visible Rebase keeps history clean Understanding this cleared a big confusion for me. ✅ Handling Merge Conflicts This is where real learning happens. Instead of fearing conflicts, I now see them as part of collaboration. 🔥 Key Realization Git is not just a tool. It is: The foundation of CI/CD The backbone of team collaboration The first step toward automation Without Git, DevOps cannot exist. #DevOps #Git #VersionControl #LearningInPublic #FutureDevOpsEngineer
