Learn how to build Continuous Integration/Continuous Deployment (CI/CD) Pipeline with Jenkins

In my article A beginner’s guide to building DevOps pipelines with open source tools, I shared a story about building a DevOps pipeline from scratch. The core technology driving that initiative was Jenkins, an open source tool to build continuous integration and continuous delivery (CI/CD) pipelines.

At Citi, there was a separate team that provided dedicated Jenkins pipelines with a stable master-slave node setup, but the environment was only used for quality assurance (QA), staging, and production environments. The development environment was still very manual, and our team needed to automate it to gain as much flexibility as possible while accelerating the development effort. This is the reason we decided to build a CI/CD pipeline for DevOps. And the open source version of Jenkins was the obvious choice due to its flexibility, openness, powerful plugin-capabilities, and ease of use.

In this article, I will share a step-by-step walkthrough on how you can build a CI/CD pipeline using Jenkins.
