Automating Git Releases with Hooks in DevOps

🚀 DevOps Journey – Day 13 / 100 Today I started learning Git (Version Control System) 🔧 — one of the most important tools in DevOps. 🔹 What is Git? • Git = Distributed Version Control System (DVCS) • Helps track changes in code and maintain history 🔹 Evolution of VCS: • SCCM → RCS → CVS → SVN → Git 🔹 Git Stages: • Working Directory • Staging Area • Repository 🔹 Hands-on Practice: 📌 Setup Git: • Launch EC2 instance • Switch to root → sudo su • Install Git → yum install git -y • Check version → git --version 📌 Initialize Repository: • mkdir project && cd project • git init 📌 File Tracking: • touch file1 • git status • git add file1 • git commit -m "this is example" 📌 More Operations: • git add * • git commit -m "your message" 📌 Viewing History: • git log • git log -2 • git log --oneline • git log --pretty=oneline 📌 Commit Details: • git show <commit_id> • git show <commit_id> --stat 💡 Key Insight: Git helps in tracking changes, collaboration, and rollback — making it a core skill for every DevOps engineer.

🚀 DevOps Learning Series Git Merge vs Git Rebase — two ways to combine code, one way to start arguments 🧑💻🍿 When multiple developers touch the same repo, Git has two main ways to bring branches together: Merge and Rebase. - Both work. - Both are powerful. - Both can ruin your day if used wrong. 🔀 Git Merge (The Honest Historian) git merge feature-branch What it does: - Combines branches - Keeps complete commit history - Creates a merge commit 🧠 Think of it like: Two timelines meeting and saying “Let’s record exactly what happened.” ✔ Safe ✔ Transparent history ✔ Good for shared branches 🧹 Git Rebase (The History Cleaner) git rebase main What it does: - Replays your commits on top of another branch - Creates a linear history - No extra merge commit 🧠 Think of it like: Pretending your branch started from the latest code all along. ✔ Cleaner commit history ✔ Easier to read logs ✔ Preferred before merging PRs ⚠️ DevOps Golden Rule Never rebase shared or public branches. Because rewriting history in a team repo is like editing the past in a shared Google Doc 😅 💡 TL;DR merge → honest history rebase → clean history Both are useful. Just don’t time-travel in a shared branch 🚀 #DevOps #Linux #CloudComputing #SystemAdministration #LearningInPublic #TechCareers #TrainWithShubham

🚀 DevOps Journey – Git Learning Progress Today I focused on strengthening my Git fundamentals as part of my DevOps preparation. 📌 Topics I practiced: - git config – setting up user identity and configurations - git reset – undoing changes and managing commits - .gitignore – excluding unnecessary and sensitive files - git reflog – tracking and recovering lost commits - git cherry-pick – applying specific commits across branches 💡 Key Takeaways: Understanding these commands is crucial for handling real-time scenarios like fixing production issues, managing commits efficiently, and maintaining clean repositories. 🔧 Real-world relevance: - Recovering lost commits using reflog - Applying hotfixes using cherry-pick - Avoiding sensitive data exposure using .gitignore 📈 Consistent practice is helping me build confidence in version control, which is a core skill in any DevOps role. #DevOps #Git #Linux #LearningJourney #VersionControl #Cloud #ContinuousLearning

Today, I learned the fundamentals of Git, a powerful version control system used in software development. 🔹 Key things I explored: What Git is and why it is used Basic commands like git init, git add, git commit Understanding repositories and version tracking Importance of version control in team collaboration This is an important step in my journey towards mastering DevOps and improving my development workflow.

Day 30 - Git Hard Reset #100DaysOfDevOps🧑💻 Today’s task focused on rewriting Git history in a controlled environment. A skill that directly translates to real-world production support. The Nautilus team had a test repository where multiple temporary commits were pushed. The requirement was clear: clean up the repository so only two commits remain in history with both the branch pointer and HEAD aligned to one of the commits. To achieve this, I navigated to the repository, identified the correct commit using "git log --oneline", and executed a "git reset --hard commit-hash" to move the branch pointer and HEAD back to the required state while cleaning the working tree. Since this rewrites commit history, I followed up with a "git push --force" to update the remote repository safely. This reflects real production scenarios where accidental commits, sensitive data exposure, or test changes must be surgically removed while keeping repository integrity intact. Understanding when and how to rewrite history, and the risks involved, is critical in DevOps and release engineering workflows. Full documentation and command breakdown available here: https://lnkd.in/g-HZxwzw Another solid step forward. Excited to tackle tomorrow’s challenge and keep building production-ready Git expertise. 🚀 #DevOps #Git #VersionControl #CloudEngineering #SRE #Linux #ContinuousLearning

🚀 New Blog Published: From Git Basics to GitHub Workflows – A DevOps Perspective In my DevOps learning journey, after exploring Linux and Computer Networking, the next important tool I focused on was Git and GitHub.

🚀 Day 2 of My DevOps Journey — Git (Where Real Collaboration Begins) Yesterday was Linux. Today, I stepped into Git — the backbone of DevOps workflows. At first, Git felt simple… until I actually started working with it. 🔹 What I Practiced: Initializing a repo (git init) Branching strategy (main, feature/*) Merging vs Rebasing Fixing merge conflicts Using git stash when switching work Writing meaningful commit messages 🔹 Real Challenge I Faced: I accidentally: ❌ Made changes on the wrong branch ❌ Used stash incorrectly ❌ Faced merge conflicts And honestly… this is where real learning started. 🔹 What I Learned: ✔ git rebase helps keep history clean ✔ Merge conflicts are not errors — they are decisions ✔ Commit messages matter more than we think 💡 Key Learning: “Git is not about commands. It’s about thinking in versions.” I also practiced: Squashing commits using interactive rebase Understanding how teams collaborate using PRs This felt like a big step toward real-world DevOps work. Next → Docker (containers, images, real deployment) If you’ve struggled with Git before, you’re not alone. Let’s grow together 🤝 #DevOps #Git #VersionControl #Cloud #LearningInPublic #BuildInPublic #CI_CD
