Jenkins Git Integration –Useful for Every DevOps Professional

Jenkins Git Integration – Essential for Every DevOps Professional

Introduction

Jenkins and Git are two of the most powerful tools in the DevOps ecosystem. Jenkins automates software development workflows, while Git provides version control, enabling seamless collaboration among developers. Integrating Jenkins with Git streamlines the development process, enhances efficiency, and supports continuous integration and deployment (CI/CD).

In this guide, we will explore:

  • What Git is and how it works

  • An overview of Jenkins

  • Why Git and Jenkins are used together

  • Step-by-step guide to integrating Git with Jenkins

What is Git?

Git is a distributed version control system (DVCS) that enables developers to track changes, collaborate efficiently, and maintain code stability. Before Git, developers relied on centralized version control systems (CVCS), which had limitations such as dependency on a central server and vulnerability to data loss.

Types of Version Control Systems (VCS)

  1. Centralized Version Control System (CVCS)

    • Uses a single central repository to store all files.

    • Requires network connectivity to access and modify files.

    • Risk of data loss if the central repository is compromised.

  2. Distributed Version Control System (DVCS) (e.g., Git)

    • Each developer maintains a local copy (clone) of the repository.

    • Changes are committed locally and synchronized with the central repository.

    • No dependency on network availability for local development.

What is Jenkins?

Jenkins is an open-source automation tool written in Java, designed to facilitate continuous integration and continuous deployment (CI/CD). Jenkins automates software build, testing, and deployment processes, reducing manual effort and increasing efficiency.

Key Features of Jenkins:
