Building an End-to-End CI/CD Pipeline with Jenkins

In today’s fast-paced software development landscape, continuous integration and continuous delivery (CI/CD) have become indispensable practices for ensuring efficiency, reliability, and agility in software development workflows. Jenkins, an open-source automation server, plays a crucial role in enabling teams to implement CI/CD pipelines efficiently. In this blog post, we will embark on a journey to build an end-to-end CI/CD pipeline using Jenkins, covering everything from installation to deployment.

Introduction to Jenkins:

Brief overview of Jenkins and its importance in CI/CD.

Explanation of key concepts such as jobs, pipelines, and plugins.

Setting Up Jenkins:

Introduction to Jenkins Pipelines:

Understanding the concept of Jenkins pipelines.

Syntax overview (Declarative vs. Scripted pipelines).

Benefits of using pipelines for CI/CD.

Building a CI Pipeline:

Designing a CI pipeline for automated build and test processes.
