Day 12 : Deep Dive in Git & GitHub for DevOps Engineers

Introduction

Hey DevOps Enthusiasts! 🚀

Welcome to Day 12 of our DevOps journey. Today, we are diving deep into Git and GitHub, essential tools for any DevOps engineer. By the end of this blog, you'll have a solid understanding of these tools and be able to perform key tasks with ease. Let's get started! 🌟

What is Git and Why is it Important?

Git is a distributed version control system designed to handle everything from small to very large projects with speed and efficiency. It allows multiple developers to work on a project simultaneously without overwriting each other's changes. This capability is crucial for collaboration and maintaining a history of changes, which helps in tracking and reverting to previous versions if necessary.

What is the Difference Between Main Branch and Master Branch?

Traditionally, the default branch in Git repositories was named "master." However, to promote more inclusive terminology, many platforms, including GitHub, have switched to using "main" as the default branch name. Functionally, both branches serve the same purpose—they are the default branches where production-ready code resides.

Can You Explain the Difference Between Git and GitHub?

Git is a version control system that allows you to manage and track changes to your code. GitHub, on the other hand, is a cloud-based hosting service for Git repositories. It provides a web-based interface to Git and additional features like pull requests, issue tracking, and project management tools, making it easier for teams to collaborate on projects.

How Do You Create a New Repository on GitHub?

Creating a repository on GitHub is straightforward:

1. Sign in to your GitHub account.

2. Click on the "+" icon at the top right and select "New repository."

3. Name your repository "DevOps."

4. Optionally, add a description, choose to make it public or private, and initialize it with a README file.

5. Click "Create repository."

   

What is the Difference Between a Local & Remote Repository? How to Connect Local to Remote?

A local repository resides on your local machine, while a remote repository is hosted on a server, like GitHub. To connect a local repository to a remote one:

1. Navigate to your local repository in the terminal.

2. Use the command: git remote add origin <repository-URL>

3. Push your local changes to the remote repository with: git push -u origin main

Tasks

Task 1: Set Your User Name and Email Address

To configure your Git user details, use:

git config --global user.name "Your Name"
git config --global user.email "your.email@example.com"

Task 2: Create and Connect a Repository

1. Create a repository on GitHub: Follow the steps mentioned above to create a repository named "DevOps."

2. Connect your local repository:

    git init
    git remote add origin https://github.com/yourusername/DevOps.git
   

   

   

   

   

   

3. Create and add a file:

    mkdir -p DevOps/Git
    echo "Content for Day-02" > DevOps/Git/Day-02.txt
    git add DevOps/Git/Day-02.txt
    git commit -m "Add Day-02.txt with initial content"
    git push -u origin main
