📘 #100DaysOfDevOps – Day 11 (GitHub – Day 2) Today I learned about Branching and Merging in Git 🌿 Branching is one of the most powerful features of Git. It allows developers to work on different features without affecting the main code. --- 🔹 What is a Branch? A branch is a separate line of development. 👉 Default branch: "main" --- 🔹 Why Branching is Important? • Work on features independently • Avoid breaking main code • Collaborate easily with teams --- 🔹 Important Commands Create a branch "git branch feature-1" Switch to branch "git checkout feature-1" (Create + switch) "git checkout -b feature-1" View branches "git branch" --- 🔹 Merging Branches Switch to main branch "git checkout main" Merge branch "git merge feature-1" --- 🔹 Key Concept 👉 After merging, changes from feature branch are added to main branch. --- 💡 Key Learning: Branching and merging help teams collaborate efficiently, manage features, and maintain clean code in real DevOps projects. Learning something new every day 🚀 #100DaysOfDevOps #DevOps #Git #GitHub #LearningInPublic

🚀 #100DaysOfDevOps – Day 8 Today I practiced Git branching, merging, and revert operations, focusing on real-time development and production scenarios. 🔹 Git Revert (Safe Rollback) Used to undo a specific commit without removing history. ✔ Scenario: Reverting a faulty production deployment safely ✔ Scenario: Fixing bugs without affecting commit history Command: git revert <commit-id> 🔹 Git Branching (Parallel Development) Branches allow independent development without affecting main code. ✔ Scenario: Creating feature branches for new changes ✔ Scenario: Isolating bug fixes from production code Commands: git branch git branch feature-branch git checkout feature-branch git checkout -b feature-branch 🔹 Branch Management ✔ Scenario: Cleaning up unused branches after release ✔ Scenario: Renaming branches based on project needs Commands: git branch -m old-name new-name git branch -d branch-name git branch -D branch-name 🔹 Git Merge (Combining Changes) Used to merge code from one branch to another. ✔ Scenario: Merging feature branch into main branch after testing ✔ Scenario: Deploying finalized changes to production Command: git merge branch-name 💡 Branching and merging are core to team collaboration, CI/CD pipelines, and release management in DevOps. Learning how to manage code flow effectively across environments. 💪 #Git #DevOps #VersionControl #Branching #CloudEngineering #100DaysChallenge #ContinuousLearning
