Deep Dive in Git & GitHub for DevOps Engineers.

What is Git and why is it important?

It is a DevOps tool used for source code management. The main purpose of Git is to manage different versions of a project, which could be source code, documents, large data sets, or anything else you wish to track. It allows multiple people to work on a project simultaneously, without overwriting each other's changes

Why it is important:

• Version control & collaboration

• Backup & Restore

• Branching & Merging

• Staging Area

• Distributed System

• Speed & it is open source.

  What is difference Between Main Branch and Master Branch??

The "main" and "master" branches have the same purpose: they both represent the default branch of a repository. The term "master" has traditionally been used as the default branch in Git. Later it become "main" as the default branch name instead.there isn't a functional difference between "main" and "master" branch. The difference lies primarily in the naming convention.

Can you explain the difference between Git and GitHub?

• Git is a version control system that allows the developer to track their code while GitHub is a web-based graphical interface that hosting service for git repository.

• Git is a software while GitHub is a service.

• Git is maintained by Linux while Github is maintained by Microsoft.

• Git is a command-line tool while Github provides a graphical interface.

• Git has no user while Github has a built-in user.

• Git is installed locally on the system while GitHub is hosted on the web.

  How do you create a new repository on GitHub?

  • Sign in to your GitHub account.

  • Click on the '+' icon at the top right corner of your GitHub homepage. From the dropdown menu, select 'New repository'.

  • You'll be directed to a new page - Here fill the details include repo name, description ,visibility etc.

  • Create repository at the bottom of page.

    What is difference between local & remote repository? How to connect local to remote?

    Local repository:

    • A local repository is present on your local machine.

    • It contains all the files, commits, branches, and history of your project.

    • We have direct access to it, and we can work on our project without an internet connection.

    • If we make any changes to files in the local repository. It can be tracked and committed locally.

Remote repository:

• A remote repository is hosted on a server like GitHub or GitLab.

• It is a central location where multiple developers can collaborate on a project.

• It provides us backup of code and allows us to easily share and collaborate.

• It allows team members to access the latest changes made by others and to contribute to their changes.

Task-1: Set your user name and email address, which will be associated with your commits.

git config --globaluser.name"GitHub username"

git config --globaluser.email"Github email"

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-02.txt & add some content to it

• Push your local commits to the repository on GitHub

Step 1: Open the GitHub account and create a Git repository named DevOps.

• Connect your local repository to the repository on GitHub.

  • Push your local commits to the repository on GitHub.

    #git init

    #mkdir git

    #vim day2.txt

    xyz......

    #cd git

    #git add .

    #git status

    #git branch -M main - change branch to main from master

    

    #git commit -m "made some changes in file"

    

    #git branch -M main - change branch to main from master

    

    Create token for authentication:

    Github > profiles > settings > Developer settings > personal access tokens > classic token > generate a personal token > set expiry date > select scopes > create token > copy & paste on notepad for later use.

    #git push -u origin main
