💻 What is Git? || Push | pull | commit code Git is a free and open-source Distributed Version Control System (DVCS) designed to handle everything from small to very large projects with speed and efficiency. In simple terms, Git is a system that tracks every change made to a file or set of files over time. It allows developers to collaborate on a project, efficiently manage changes, and revert to any previous version of the code at any point. ☁️ Git in the DevOps World Git is the foundation of the DevOps lifecycle, specifically for the "Plan" and "Code" phases. Collaboration: Git allows multiple developers and DevOps engineers to work on the same source code (and Infrastructure-as-Code files like Terraform or Ansible playbooks) simultaneously without conflicting. Traceability: Every deployment can be traced back to a specific commit in Git, which is crucial for troubleshooting, auditing, and adhering to compliance standards. Continuous Integration/Continuous Delivery (CI/CD): CI/CD pipelines (using tools like Jenkins, GitLab CI, or GitHub Actions) are almost always triggered by an action in Git (like a code push or a merge request). Git is the fundamental technology, while platforms like GitHub, GitLab, and Bitbucket are web-based hosting services for Git repositories, adding collaboration features like user management and Pull Requests. 🔑 Key Concepts and Function 1. Version Control System (VCS) Version Control: Think of it like a time machine for your code. If you introduce a bug, you can instantly rewind the entire project to a point where it was stable. It eliminates the need for files named project_final_v1.0, project_final_v2.1, etc. Distributed: This is Git's most powerful feature. Unlike older Centralized VCS (like Subversion or CVS) which relied on a single central server, Git gives every developer a full copy (or clone) of the entire project history on their local machine. This makes Git extremely fast, as most operations (like viewing history or committing changes) are local. It also provides a powerful backup, as the loss of the central server doesn't mean the loss of the entire project history. Essential Terminology Repository (Repo): The project folder containing your code files and a hidden .git directory, which holds the entire project history. Commit: A "save point" or snapshot of your project at a specific time, identified by a unique ID (SHA hash) and including a descriptive message. Branch: An independent line of development. Developers use branches to work on a new feature or fix a bug without affecting the main, stable code. Merge/Pull Request (PR): The process of integrating changes from a completed branch back into the main line of code. PRs are used on platforms like GitHub or GitLab to review the code before merging. 🧩 Key Features of Git Version Control – Keeps a complete history of all changes to files in a project. You can revert to previous versions anytime. Distributed System – Every developer has a full copy of the repository on their local machine, not just on a central server. Branching & Merging – Create branches to work on features or fixes independently, then merge them back into the main code. Collaboration – Git allows teams to work together without conflicts using platforms like GitHub, GitLab, or Bitbucket. Tracking Changes – Records who changed what and when, helping with debugging and accountability.
