🌟 Java Sample CI/CD Project 🌟

A showcase of a CI/CD pipeline for a Java application using Jenkins, Docker, and SonarQube. This project walks through a streamlined process to build, test, and deploy a Java application using modern DevOps practices.

---

📂 Project Structure

• Dockerfile - Contains instructions for building the application image.
• How to Install Sonarqube in Ubuntu Linux.md - Guide to set up SonarQube on Ubuntu.
• Jenkinsfile - CI/CD pipeline configuration for Jenkins.
• pom.xml - Maven configuration file.
• server/ - Contains backend service code.
• webapp/ - Contains frontend web application code.

---

📋 Prerequisites

Before running the pipeline, make sure the following tools are installed:

• Jenkins - To automate CI/CD tasks.
• Docker - Required for building and pushing Docker images.
• SonarQube - For analyzing code quality.
• Maven - Used for building the Java project.

🏁 Getting Started

1. Clone the Repository

Clone the repository to your local machine using:

git clone https://github.com/SaraIravani/Java-sample-ci.git
cd Java-sample-ci

2. Configure Jenkins

• Plugins: Install essential Jenkins plugins, including Pipeline, Docker, and SonarQube.
• Credentials:
  • GitHub: Create a credential for accessing your GitHub repository.
  • SonarQube: Add a token for SonarQube analysis.
  • DockerHub: Set up Docker credentials for pushing images.

3. Update the Jenkinsfile

The Jenkinsfile defines the stages for building, testing, and deploying the application. Key pipeline stages include:

• SCM Checkout - Clones the repository.
• Build - Compiles the application using Maven.
• Test - Runs unit tests.
• SonarQube Analysis - Performs code quality analysis.
• Docker Image Build & Push - Builds and pushes the Docker image to DockerHub.
• CD Pipeline Trigger - Initiates the continuous deployment pipeline.

4. Build & Deploy

1. Create a new pipeline job in Jenkins and point it to your Jenkinsfile.
2. Run the job to execute the complete CI/CD pipeline.
