Day 8 Task: Basic Git & GitHub for DevOps Engineers.

Welcome to Day 8 of our DevOps journey! Today, we dive into the fundamental world of Git and GitHub. ??

?? What is Git?

Imagine a magical librarian that keeps track of every change made to a book, and not just that, it allows multiple people to write in the same book at the same time without messing it up. That's what Git is for your code! It's a clever tool that records who did what to your files and lets you rewind time if something goes wrong.

? Key Git Benefits:

• Keep track of changes ??
• Collaborate seamlessly ??
• Go back in time ?

?? What is GitHub?

GitHub is like the stage where Git performs its magic show. It's a platform that takes Git and puts it on the web, making it super easy for people to share and work together on code. Think of it as a collaboration hub where developers from all around the world can join forces.

?? GitHub Features:

• Version control on the web ??
• Collaboration made simple ??
• Home for open-source projects ??

?? What is Version Control?

Imagine you have a magical notebook that remembers every change you make to your homework. If you ever mess up, you can just look back and find your previous versions. That's version control! It's like a time machine for your work. ???

?? Two Types of Version Control:

1. Centralized Version Control Systems (CVCS):Think of this as a single library with all the books. You borrow a book, make changes, and put it back.Examples: Subversion, Perforce.
2. Distributed Version Control Systems (DVCS):In this library, everyone has their copy of all the books. You can read and write independently, and then merge your changes.Examples: Git, Mercurial, Darcs.

?? Why Choose DVCS Over CVCS?

?? Better Collaboration: In DVCS, everyone has their copy, so you can work together without waiting in line.

? Improved Speed: DVCS is super fast because you don't need to go to the central library all the time.

?? Greater Flexibility: You can work offline and decide when to share your changes, unlike CVCS where you must always connect to the central library.

??? Enhanced Security: With your book copies in many places, it's hard to lose them all. CVCS relies on one library, which can be risky.

?? Task List:

1. Install Git: If you haven't already, download Git here. It's your magical librarian.
2. Create a GitHub Account: If you don't have one yet, sign up here. This is your backstage pass to collaboration.

?? Exercises:

• ?? Step 1: Create a New RepositoryTo create a new repository on GitHub, you can also use the GitHub web interface. Follow these steps:Go to the GitHub website (https://github.com/).Log in to your GitHub account (or create one if you haven't already).Click on the "+" icon in the top right corner and select "New repository."Fill in your repository name, a brief description (optional), choose visibility (public or private), and select a license (if applicable).Click the "Create repository" button.
• ?? Step 2: Make Some ChangesNow, let's dive into the scriptwriting part. Pick a file in your local directory (or create one) and make some changes to it. Use your favorite text editor or command-line tools. For example, if you have a file called script.txt, you can modify it with:

# Replace 'script.txt' with the name of your file
nano script.txt        

Edit your file, save your changes, and exit the text editor.

• ?? Step 3: Push Your Changes

The curtain is about to rise, and it's your time to shine! Use Git, your trusty backstage manager, to commit and push those changes to your GitHub repository. Here's how you do it:

# Initialize Git in your local directory (if you haven't already)

git init        

# Add the changes you made

git add .        

# Commit the changes with a meaningful message

git commit -m "Updated script.txt"        

# Set the remote repository URL # Replace 'your-github-username' and 'your-repo-name' with your actual username and repository name:

git remote add origin https://github.com/your-github-username/your-repo-name.git        

# Push your changes to GitHub :

git push -u origin master        

Keep practicing, and soon you'll be

a DevOps magician, orchestrating your code effortlessly. Stay tuned for Day 9, where I'll explore more DevOps wonders! ?????? #DevOpsJourney #GitGitHubMastery #DevOpsJourney #CodePerformance #TWS #Git Shubham Londhe
