Kubernetes CI/CD with Helm Jenkins and SonarQube for Java Apps

Overview

This project demonstrates a complete CI/CD (Continuous Integration/Continuous Deployment) pipeline for Java applications on a Kubernetes cluster. It integrates popular tools such as Helm, Jenkins, and SonarQube to automate the build, test, and deployment processes.

Features

• Automatic build and deployment of Java applications.
• Kubernetes Helm charts for application packaging.
• Jenkins for CI/CD pipeline orchestration.
• SonarQube for code quality analysis.
• Kubernetes for scalable and containerized application deployments.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Kubernetes cluster up and running.
• Helm installed on your Kubernetes cluster.
• Jenkins server deployed and accessible.
• SonarQube server for code analysis.
• Java development environment.

Prerequisites

• JDK 1.8 or later
• Maven 3 or later
• MySQL 5.6 or later

Technologies

• Spring MVC
• Spring Security
• Spring Data JPA
• Maven
• JSP
• MySQL

Database

Here,we used Mysql DB MSQL DB Installation Steps for Linux ubuntu 14.04:

• $ sudo apt-get update
• $ sudo apt-get install mysql-server

Then look for the file :

• /src/main/resources/accountsdb
• accountsdb.sql file is a mysql dump file.we have to import this dump to mysql db server

• mysql -u <user_name> -p accounts < accountsdb.sql
