Basic Git & GitHub for DevOps Engineers

Git: Git, a free and open-source distributed version control system, empowers developers to collaborate seamlessly on projects of any scale. With features for sharing and merging code changes, it allows developers to work independently on their local repositories, later consolidating changes into a unified codebase. Notably, Git simplifies branching and merging, enabling the creation of separate development lines for testing new features.

GitHub: As a web-based platform, GitHub is a powerhouse for storing and managing code repositories. It fosters collaboration with tools for version control, multi-developer collaboration, issue tracking, and project documentation. It's not just a code repository; it's a hub for efficient and transparent teamwork.

Version Control System (VCS) Types: Understanding Version Control Systems is crucial. Local VCS, Centralized VCS, and Distributed VCS each serve distinct purposes. Distributed VCS, where each developer has a complete repository copy, offers flexibility, fault tolerance, and offline capabilities, making it an excellent choice for diverse and distributed teams.

Why use Distributed VCS over Centralized VCS:

• Flexibility: Allows separate branches for features/experiments.
• Fault Tolerance: Individual copies protect against data loss.
• Offline Work: Developers can make changes without an internet connection.

Creating a New Repo on GitHub & Cloning: A step-by-step guide on creating a new repository on GitHub, including cloning it to a local machine. Essential for establishing a seamless workflow between remote and local repositories.

Changes to a File in the Repo and Committing with Git: Demonstrating how to create and commit changes to a repository using Git. Including the use of "git status," "git add," and "git commit" commands for efficient version control.

Secure Access with Personal Access Token: Enhance security and streamline GitHub interactions by replacing passwords with personal access tokens. A step towards secure and efficient DevOps workflows.
