Git Guide for DevOps Beginners: Master Version Control

❓ Ի՞նչ է Git Flow-ն Git-ն այն հիմնական գործիքն է, որին պետք է տիրապետի յուրաքանչյուր դեվելոփեր, ու կարծում եմ՝ դրանով գրագետ աշխատելը շատ կարևոր է ցանկացած նախագծում։ Գոյություն ունեն Git-ով աշխատելու տարբեր մոտեցումներ, բայց այսօր կխոսենք ամենահայտնիներից մեկի՝ Git Flow-ի մասին։ Այն ամենատարածված workflows-ներից մեկն է։ Ինչպե՞ս է աշխատում Git Flow-ն։ Git Flow-ն հիմնված է մի քանի հիմնական ճյուղերի (branches) վրա, որոնցից յուրաքանչյուրն ունի իր կոնկրետ նպատակը. • main – Պարունակում է production-ի համար պատրաստի կոդը։ Այստեղ յուրաքանչյուր commit նշանակում է կայուն release: • release – Ստեղծվում է develop-ից՝ նոր release-ի պատրաստվելիս։ Այն օգտագործվում է վերջնական թեստավորման և մանր bug-երի ուղղման համար՝ նախքան main-ի և develop-ի մեջ merge անելը։ • develop – Հիմնական մշակման ճյուղն է։ Feature branch-երը ստեղծվում են հենց այստեղից, իսկ աշխատանքն ավարտելուց հետո՝ նորից միացվում (merge) develop-ին։ • feature – Յուրաքանչյուր նոր ֆունկցիոնալ մշակվում է առանձին branch-ում, որը ստեղծվում է develop-ից և ավարտից հետո հետ միացվում դրան։ • hotfix – Ստեղծվում է անմիջապես main-ից՝ production-ում ծագած խնդիրներն արագ ուղղելու համար։ Ուղղումից հետո այն merge է արվում և՛ main-ին, և՛ develop-ին՝ բոլոր ճյուղերը թարմ պահելու համար։ Ինչու՞ օգտագործել Git Flow: Եթե նախագիծը փոքր է և թիմում քիչ մարդիկ են, Git Flow-ն երևի ամենալավ ընտրությունը չլինի։ Բայց եթե մեծ, արագ զարգացող և բազմաֆունկցիոնալ նախագծի է, որտեղ ներգրավված է մեծ թիմ, ուրեմն Git Flow-ն իդեալական տարբերակ է։ 👇 English Below ❓ What is Git Flow? Git is the main tool that every developer should know, and I think working with it is very important in any project. There are many different approaches to working with Git, but today we will talk about the most well-known one - Git Flow. Git Flow is one of the most widely used Git workflows in software development. How does Git Flow work? Git Flow is based on several key branches, each with its own purpose: • main - Contains production-ready code. Every commit here represents a stable release. • release - Created from develop when preparing for a new release. It’s used for final testing and minor bug fixes before merging into main and develop. • develop - The main development branch. Feature branches are created from it, and after the work is done, they are merged back into develop. • feature - Each new feature is developed in its own branch, created from develop and merged back once it’s complete. • hotfix - Created from main to quickly fix production issues. Once fixed, it’s merged back into both main and develop to keep all branches updated. Why you might want to use Git Flow? If your project is small and doesn’t involve many developers, Git Flow is not the most suitable option. But if your project is large, rapidly evolving, multifunctional, and has a big team, then Git Flow is ideal for your project. #DevOps #SimplyDevOps #Git #GitFlow #GitWorkflows

🚀 Getting Started with GitLab — A Beginner’s Guide If you’re new to DevOps or CI/CD, you might have heard of GitLab — but what exactly is it, and how is it different from GitHub? Let’s break it down 👇 🧠 What is GitLab? GitLab is an all-in-one DevOps platform that lets you manage your code, collaborate with your team, and automate your development workflows — all in one place! You can use it for version control, CI/CD pipelines, issue tracking, and even monitoring deployments. 💡 Why GitLab? While GitHub is mainly focused on code hosting and collaboration, GitLab goes a step further by offering a complete CI/CD solution built right into the platform. 1)GitHub + GitHub Actions = similar to GitLab’s built-in pipelines 2)Everything from planning ➡️ coding ➡️ testing ➡️ deploying can be done inside GitLab. It’s great for teams who want one tool for everything instead of integrating multiple services. 🧩 Creating and Managing Projects & Groups: In GitLab: 1)A Group is like a folder that contains multiple Projects. 2)You can manage permissions, members, and visibility settings at both levels. ✅ Create a new project → Upload or import your code → Start collaborating with your team. ⚙️ Creating Pipelines: Pipelines in GitLab help automate your development process. You can define a pipeline in a file called .gitlab-ci.yml in your repository. Example: stages: - build - test build_job: stage: build script: - echo "Building the app..." test_job: stage: test script: - echo "Running tests..." 🔐 Variables, Secrets & Artifacts: 1)Variables: Store values like environment names or paths. 2)Secrets: Securely store sensitive info (like API keys or passwords). 3)Artifacts: Files created by jobs (like build results or reports) that can be reused in later stages. 🏃 What are Runners? Runners are the machines that actually execute your CI/CD jobs. When you push code, the runner picks up the job, runs your pipeline, and reports back the result. There are two types: 1)SaaS Runners (provided by GitLab, hosted for you) 2)Self-Hosted Runners (set up and managed by your organization for more control and customization) #devops#gitlab#cicd

Day 25 of My DevOps Journey Today, I began exploring one of the most powerful and essential tools in the DevOps world — Git 🧑💻 What is Git? Git is a distributed version control system that tracks changes in your codebase, helps you collaborate with others, and ensures every version of your project is safely stored. Instead of manually managing files or folders, Git makes it easy to: Record every change (commit) Revert to older versions Work in parallel with multiple teammates Merge updates efficiently Why Git in DevOps? ✅ Enables collaboration across teams ✅ Tracks changes for audit & rollback ✅ Integrates with CI/CD pipelines (like Jenkins, GitHub Actions) ✅ Forms the backbone of Infrastructure as Code (IaC) Common Git Commands git init # Create a new repository git clone <url> # Download an existing repo git add . # Stage changes git commit -m "msg" # Save changes git status # View current repo state git log # View commit history git push origin main # Upload code to remote repo git pull # Fetch and merge latest changes Tip: Commit often, with clear messages every commit should represent a meaningful change. What do you use for version control GitHub, GitLab, or Bitbucket? #Day25 #DevOpsJourney #Git #VersionControl #GitHub #GitLab #Bitbucket #DevOps #LearningInPublic #Automation #Collaboration #TechLearning #CloudComputing #InfrastructureAsCode

🚀 Git assignments are the fastest way for DevOps beginners to build rock-solid version control and collaboration habits. 🚀 If you want reliable pipelines, you must master Git early. A practical, hands-on path helps you learn by doing, not just reading. What you’ll gain from a Git assignment track: ➡️ Master the basics: init, clone, add, commit, status, log, diff ➡️ Practice branching and merging: create feature branches, merge, and resolve conflicts ➡️ Collaborate like a pro: work with remotes, pull requests, code reviews ➡️ Understand workflows: GitHub Flow, Git Flow, and when to use each ➡️ Tidy up after yourself: revert, reset, and meaningful commit messages ➡️ Prepare for CI/CD: triggering builds from commits and small release tags How to apply this in your learning: ➡️Fork a small project or create a tiny repo ➡️Add a feature, then open a PR (even if only to yourself) ➡️Write clear, atomic commits with meaningful messages ➡️Reflect on what went well and what caused conflicts, and iterate #Git #VersionControl #DevOps #

# DevOps: Day 12 - Git and GitHub - The fundamentals of git and github is version control system. - The two problems version control systems solve are * Versioning. * Sharing of code. - Some of the version control system we have are: * CVS: Centralized * SVN: Centralized * Git: Distributed - Fork is creating an entire copy of the original source code as your own copy. - Git is a distributed version control system. And it is an open source tool. - Github (bitbucket etc.) is a solution that is built ontop of git. Used for project management, keeping of code, code review, comment etc. - To see everything under git, all the options, simply type `git` on The terminal and Press enter. - To initialize git, use `git init` this will initialize an empty git repository. - Every DevOps Engineer should understand the lifecycle of git. Which are the three basic commands of: * git add: track file(s) * git commit: tell git what changes you have made in those/that file. * git push - git diff: to check for the exact changes that were/was made. - git log: to check for all the commits for a file/files. - Lets say you have a project having two versions committed, and then you're asked to return to the first version (first commit), here is what you're supposed to do: * use git log to check for all commits * copy the commit hash i.e the first commit hash * git reset --hard <commit hash>. So technically, one can go back to any previous version of His/Her code with git. - To share code within the distributed system is where github/bitbucket/gitlab comes in.

DevOps Revisit — Git Branching Strategies 🔀 Git Flow vs Trunk-Based vs GitHub Flow Today, I revisited one of the most fundamental yet often overlooked topics in DevOps — how we branch, collaborate, and deliver code. While exploring Git Flow, Trunk-Based, and GitHub Flow, I realized something simple but powerful: your branching strategy doesn’t just define how you write code — it defines how your team thinks, collaborates, and ships reliably. 💡 Git Flow gave me a sense of structure — perfect for large, versioned releases. ⚡ Trunk-Based showed me what true CI/CD speed looks like — constant integration and feedback. 🚀 GitHub Flow reminded me how simplicity can empower teams to move fast without friction. Each has its own rhythm, and choosing the right one depends on your team’s maturity, automation, and goals. The deeper I went, the more I understood why branching isn’t just a version control strategy — it’s a DevOps philosophy. #DevOpsRevisit #Git #BranchingStrategy #CICD #DevOps #GitFlow #TrunkBasedDevelopment #GitHubFlow #SoftwareEngineering
