Day 9 Task: Deep Dive in Git & GitHub for DevOps Engineers.

Difference between the main branch and the master branch?

Master Branch:-

When the developer created a repository and many branches are available. But the final and accurate code is kept at a single branch which is the master branch. In this master branch, not everyone makes changes only correct code is taken from other branches and pushed into the master branch. In git by default branch is the master branch.

Main Branch:- The meaning of master and the main branch is the same but it uses master and GitHub uses main that's it. Because in October 2020, the GitHub company changed the term from “master” to “main”.

Difference between Git and Github?

How do you create a new repository on GitHub?

After you create your GitHub account, click on the + button and select a new repository. After that, type the repository name and add a simple description. It will create an empty public repository.

After creating the repository on GitHub, it will provide a detailed guide on how to clone, add remote, and initialize a Git project.

Difference between local and remote repositories? how to connect locally to the remote repository?

A local repository is a copy of a Git repository that is stored on your local computer, while a remote repository is a copy of the same repository that is hosted on a remote server, such as GitHub

task-1:

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

  To set a user name.

  sudo git config --global user.name "Your Name"

  To set email id.

  sudo git config --global user.email "your.email@example.com"

  verify user name and email.

  sudo git config --list

• git config --the list is used to show the list of usernames and emails.

task-2:

perform push and pull and transfer repository from local to GitHub and GitHub to local git.

following are the steps follow as it is:-

1. create the folder devops-eng-batch. eg. mkdir DevOps-eng-batch

2. Go into a folder. cd devops-eng-batch

3. Create a file. touch hello.txt

4. now use the git init command.

1. provide a username and email id compulsory otherwise, it takes both by default.
   sudo git config --global user.name "Your Name"
sudo git config --global user.email "your.email@example.com"

   

2. Add file to git.

   

   When you add a file it goes into the staging state.

3. Commit the file. When you commit the file it is stored in the git folder.

   

4. So the file is added to the local Git folder. Now we want to send this to our GitHub repository. So before that create a repository in Github of "devops-zero-to-hero-english".

5. (For my reference, I have created one more file but you can carry it with the previous file). Again i have committed my_test_file.txt to local Git. Now, I have transferred this file to GitHub at "devops-zero-to-hero-english". To create a token Go to settings->Devloper Settings->personal Access token->Token classic->Generate new token->Click on all repositories ->Generate Token. Copy that token.

6. Use the command:- git remote set-url origin https://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@github.com/VibhutePooja283/devops-zero-to-hero-english.git
   So with the help of this, there is no need to provide a username or password. But we provide the authenticated token to them.
   Format of URL:- git remote set-url origin http://token@github.com/writepart after HTTPS. You will get this format by git remote -v.

   

7. Then push your file to the GitHub repository. git push origin main

   

   To see the following image our my_test_file.txt comes from Git to Github.

   

1. Now Create Another File my_remote_file.txt and pull it from Github to Git, git pulls the origin main

You can check file is coming in the git local folder by ls command.

You can check to contain via the cat command.
