Git and GitHub

Git and GitHub are two closely related but distinct tools that play significant roles in modern software development, particularly in version control and collaborative coding. Let's explore each of them:

Git:

Git is a distributed version control system (VCS) that was created by Linus Torvalds in 2005. It is designed to manage source code history and facilitate collaboration among developers. Git allows developers to track changes in their code over time, create branches to work on new features or bug fixes independently, and merge changes back into the main codebase when ready. It is a powerful tool for version control and enables developers to work on the same codebase simultaneously without conflicts.

Key features of Git:

  • Distributed: Each developer has a local copy of the entire code repository, including its history. This allows developers to work offline and independently until they need to sync with the central repository.
  • Branching and Merging: Git makes branching easy, allowing developers to create separate branches for different features or bug fixes. Merging branches back into the main codebase is straightforward and helps in avoiding conflicts.
  • History and Commits: Git maintains a complete history of all changes made to the codebase. Each set of changes is recorded as a commit, providing a clear and trackable history of the project's development.

GitHub:

GitHub is a web-based platform that provides hosting for Git repositories and adds collaborative features on top of Git. It was founded in 2008 and has become one of the most popular code hosting platforms used by developers and teams worldwide. GitHub allows developers to store their Git repositories in the cloud, making it easy to access, share, and collaborate on code with other developers.

Key features of GitHub:

  • Remote Repository Hosting: GitHub provides a centralized platform where developers can host their Git repositories. This enables easy collaboration and access to code from anywhere with an internet connection.
  • Pull Requests: Developers can propose changes from their own branches (forks) to the original repository through pull requests. This feature facilitates code review and discussion before changes are merged.
  • Issue Tracking: GitHub offers an issue tracking system, which allows developers to report bugs, request new features, and track the progress of tasks.
  • Collaboration: GitHub provides tools for managing teams, assigning roles, and setting up access controls for repositories, enabling collaborative coding in a secure manner.

In summary, Git is the version control system that handles the tracking of changes and enables collaboration among developers. GitHub is a web-based platform that hosts Git repositories and adds features for code collaboration, pull requests, issue tracking, and team management. While Git can be used without GitHub (or any other remote repository hosting service), GitHub has become the most popular and widely used platform for hosting and collaborating on Git repositories.

Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server

  Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server  Objective: The objective of this experiment is to set up a CI/CD pipeline for a web development project using Jenkins, Git, and webhooks, without the need for a Jenkinsfile. You will learn how to automatically build and deploy a web application to a local HTTP server whenever changes are pushed to the Git repository, using Jenkins' "Execute Shell" build step. Introduction: Continuous Integration and Continuous Deployment (CI/CD) is a critical practice in modern software development, allowing teams to automate the building, testing, and deployment of applications. This process ensures that software updates are consistently and reliably delivered to end-users, leading to improved development efficiency and product quality. In this context, this introduction sets the stage for an exploration of how to apply CI/CD principles specifically to web development using J

Experiment No. 10 Title: Create the GitHub Account to demonstrate CI/CD pipeline using Cloud Platform.

  Experiment No. 10 Title: Create the GitHub Account to demonstrate CI/CD pipeline using Cloud Platform. Objective: The objective of this experiment is to help you create a GitHub account and set up a basic CI/CD pipeline on GCP. You will learn how to connect your GitHub repository to GCP, configure CI/CD using Cloud Build, and automatically deploy web pages to an Apache web server when code is pushed to your repository. Introduction: Continuous Integration and Continuous Deployment (CI/CD) pipelines are essential for automating the deployment of web applications. In this experiment, we will guide you through creating a GitHub account and setting up a basic CI/CD pipeline using Google Cloud Platform (GCP) to copy web pages for an Apache HTTP web application. Continuous Integration and Continuous Deployment (CI/CD) is a crucial practice in modern software development. It involves automating the processes of code integration, testing, and deployment to ensure that software changes are co

Experiment No. 6 Title: Exploring Containerization and Application Deployment with Docker

  Experiment No. 6 Title: Exploring Containerization and Application Deployment with Docker  Objective: The objective of this experiment is to provide hands-on experience with Docker containerization and application deployment by deploying an Apache web server in a Docker container. By the end of this experiment, you will understand the basics of Docker, how to create Docker containers, and how to deploy a simple web server application. Introduction Containerization is a technology that has revolutionised the way applications are developed, deployed, and managed in the modern IT landscape. It provides a standardised and efficient way to package, distribute, and run software applications and their dependencies in isolated environments called containers. Containerization technology has gained immense popularity, with Docker being one of the most well-known containerization platforms. This introduction explores the fundamental concepts of containerization, its benefits, and how it differs
