🌟 Working with GitHub: A Complete Guide for DevOps Engineers 🚀

In today's collaborative development landscape, GitHub has become an essential tool for version control and project management. As DevOps Engineers, mastering GitHub not only streamlines our workflows but also enhances team collaboration. Let's dive into the essentials of working with GitHub and Git Bash to elevate your development game! 🛠️

💻 Getting Started with GitHub

Step 1: Login to Your GitHub Account:

Begin by logging into your GitHub account with your credentials. If you don’t have an account yet, it’s time to create one!

Step 2: Create a Repository

When starting a new project, the first step is to create a repository (or repo). This is where all your project source code will be stored. Every project will have one dedicated repository. 🗂️

Note:

A unique URL will be generated for your repository upon creation, which you and your team will use to access it. For example, your repo URL might look like this:

text

https://github.com/Dondee-DevOps/01-devops-app.git

Step 3: Public vs. Private Repositories

You can create two types of repositories:

• Public Repository: Open for anyone to view, but you can specify who can modify it. 🌍

• Private Repository: Only select individuals can access and modify the code. 🔒

🛠️ Working with Git Bash

Git Bash is a powerful command-line tool that enables you to perform Git operations with ease. Here’s how to set it up:

Step 1: Download and Install Git

You can download Git from git-scm.com/downloads. Once installed, right-click in the desired directory and select “Open Git Bash Here.”

Helpful Commands:

• git help: Displays frequently used commands.

• git help <cmd-name>: Opens documentation for a specific command.

Step 2: Configure Your Git Environment

Before you start working, set up your Git environment with your name and email:

bash

git config --global user.email "dondee@gmail.com"
git config --global user.name "Dondee_DevOps"

📦 Essential Git Commands

1. Initialize a Git Repository:

   bash

    git init
   

   This command initializes your folder as a Git working tree.

2. Clone a Repository:

   bash

    git clone <project-repo-url>
   

   Download a Git repository from GitHub to your local machine.

3. Check Status:

   bash

    git status
   

   Displays staged, un-staged, and untracked files, where:

   • Staged Files: Files added for commit.

   • Un-staged Files: Modified files not yet staged.

   • Untracked Files: Newly created files not added to version control.

4. Add Files to Staging Area:

   bash

    git add <file-name>
   

   Or add all changes:

   bash

    git add .
   

5. Commit Changes:

   bash

    git commit -m 'reason for commit'
   

6. Push Changes to Remote Repository:

   bash

    git push
   

   Note: You may need to enter your GitHub account password the first time you push.

Steps to Push Code to GitHub:

1. Create a public repository on GitHub and copy the URL.

2. Clone the repository: bash

    git clone 'repo-url'
   

3. Navigate to the repository folder.

4. Create a new file: bash

    touch Demo.java
   

5. Check the file status: bash

    git status
   

6. Add to staging: bash

    git add .
   

7. Commit your changes: bash

    git commit -m 'Initial commit'
   

8. Push to the central repository: bash

    git push
   

🔄 Commit History

When you commit a change, Git generates a unique commit ID (40 characters). To view your commit history, simply use:

bash

git log

This is a fantastic way to trace your project’s evolution over time! 🕒

🚀 Bonus: Committing a Maven Project to GitHub

1. Create a Maven project.

2. Create a GitHub repository and take note of the commands displayed.

3. Open Git Bash and execute: bash

    git init
    git status
    git add .
    git commit -m 'Initial commit'
    git branch -M main
    git remote add origin <repo-url>
    git push -u origin master
   

By mastering these GitHub and Git Bash commands, you will significantly enhance your productivity as a DevOps Engineer. This will streamline your workflow, improve collaboration, and ensure you are always in control of your code! 💪✨
