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

Find the answers by your understandings (Shouldn't be copied from the internet & use hand-made diagrams) of the questions below and write a blog on it.

1. What is Git and why is it important?

Answer :

• What is Git:

  Git is a distributed version control system, used to manage versions of an application during the development of applications.

• Why Git is important:

  1. Distributed: It is a distributed version control system, which means every developer has a copy of the source code. They can even work offline if the GitHub server is down or the code is not accessible due to any issue. Changes can be made offline.

  2. Collaboration: It allows developers to copy the source code of a public repository and make changes to it, adding or updating features. This creates new opportunities for developers to contribute across the world.

  3. Version History: Git tracks all changes made to a codebase, allowing developers to roll back to a previous version if needed.

  4. Branching and Merging: It allows developers to copy production code and make changes without touching the production code by creating a separate branch. This helps to avoid issues when making changes directly to production code. Branches help test new features and updates to applications.

2. What is the difference between Main Branch and Master Branch?

Answer :

• Master Branch: The original default branch in Git, representing the primary line of development.

• Main Branch: A more modern and inclusive term used as the default branch name for new repositories, serving the same function as the master branch.

3. Can you explain the difference between Git and GitHub?

Answer :

• Git: Git is a version control system that allows developers to manage and create their repositories, commits, branches, and merges locally.

• GitHub: GitHub is also a version control system that uses Git in the background. It provides a web interface to create and manage Git repositories and adds features for collaboration, such as pull requests, issue tracking, and code reviews.

4. How do you create a new repository on GitHub?

Answer :

Creating a new repository on GitHub involves the following steps:

1. Log in to GitHub: Open GitHub and log in with your credentials.

2. Create a New Repository:

   • On the GitHub homepage, click the + button in the top-right corner and select New repository.

   • Alternatively, you can go to https://github.com/new.

3. Fill in Repository Details:

   • Repository Name: Choose a name for your repository (e.g., my-first-repo).

   • Description: Optionally, add a short description of your repository.

   • Visibility: Choose whether the repository will be public or private.

   • Initialize with a README: Optionally, check the box to add a README file to the repository.

4. Create Repository: Click the Create repository button to finalize the process.

5. What is the difference between a local & remote repository? How to connect local to remote?

Answer :

• Local Repository: A local repository is stored on our (developers') own computer. It contains our code and version history, but it's only accessible to us unless we share it.

• Remote Repository: A remote repository is hosted on a server (e.g., GitHub, GitLab, Bitbucket). It acts as a central hub where multiple developers can push and pull changes.

Tasks

Task 1:

• Set your username and email address, which will be associated with your commits.

• Output image :

  

Task 2:

• Create a repository named "DevOps" on GitHub.

  

• Connect your local repository to the repository on GitHub.

  

• Create a new file in Devops/Git/Day-12.txt & add some content to it.

  

  

• Push your local commits to the repository on GitHub.

  • Remote URL setup:

    

  • Pushing code to GitHub:
