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! π οΈ
π» Getting Started with GitHub
Step 1: Login to Your GitHub Account:
Begin by logging into your GitHub account with your credentials. If you donβt have an account yet, itβs 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. ποΈ
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. π
Private Repository: Only select individuals can access and modify the code. π
π οΈ Working with Git Bash
Git Bash is a powerful command-line tool that enables you to perform Git operations with ease. Hereβs 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 βOpen Git Bash Here.β
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"
π¦ Essential Git Commands
Initialize a Git Repository:
bash
git init
This command initializes your folder as a Git working tree.
Clone a Repository:
bash
git clone <project-repo-url>
Download a Git repository from GitHub to your local machine.
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.
Add Files to Staging Area:
bash
git add <file-name>
Or add all changes:
bash
git add .
Commit Changes:
bash
git commit -m 'reason for commit'
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:
Create a public repository on GitHub and copy the URL.
Clone the repository: bash
git clone 'repo-url'
Navigate to the repository folder.
Create a new file: bash
touch Demo.java
Check the file status: bash
git status
Add to staging: bash
git add .
Commit your changes: bash
git commit -m 'Initial commit'
Push to the central repository: bash
git push
π 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 projectβs evolution over time! π
π Bonus: Committing a Maven Project to GitHub
Create a Maven project.
Create a GitHub repository and take note of the commands displayed.
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! πͺβ¨
