Corporate CI/CD Pipeline with Docker, Jenkins, and Nexus Repository In today's fast-paced software development landscape, continuous integration and continuous deployment (CI/CD) have become essential for delivering high-quality applications efficiently. Recently, I embarked on a project to implement a CI/CD pipeline for a web application using Docker, Jenkins, and Nexus Repository. This blog outlines the journey, technical steps, and lessons learned along the way. Project Overview The objective of this project was to containerize a Java-based web application, automate the build and deployment processes, and make the application portable across various environments. To achieve this, I: Created a custom Docker image based on the vikramsinhshinde/devops:test-1 image. Integrated Jenkins to automate the build, test, and deployment workflows. Used Nexus Repository to store and manage application artifacts. Deployed the Dockerized application on different environments, ensuring...
