Introduction

In this project, we designed a CI/CD pipeline using Jenkins, integrating powerful tools like Docker, Trivy, SonarQube, and OWASP Dependency Check to achieve a secure and reliable deployment process. Here’s a step-by-step breakdown of the tools and the pipeline configuration.

Tools Used

  • GitHub: Source code hosting and collaboration.

  • Jenkins: CI/CD automation.

  • Docker: Containerization for consistent environments.

  • OWASP Dependency Check: Analyzes project dependencies for known vulnerabilities.

  • Trivy: Container vulnerability scanner.

  • SonarQube: Code quality and security analysis.

  • Node.js: Runtime environment for JavaScript, ensuring compatibility.

Pipeline Highlights

  1. Code Quality Analysis
    Using SonarQube, the pipeline checks for bugs, code smells, and vulnerabilities to maintain high standards.

  2. Vulnerability Scanning
    Trivy scans container images for security issues, while OWASP Dependency Check identifies any vulnerable dependencies.

  3. Dockerized Stages
    Each pipeline stage runs within Docker containers, ensuring consistency across different environments.

  4. Automated CI/CD Workflow
    The pipeline automates build, test, and deployment stages with integrated security and quality checks.

Step-by-Step Setup

  1. Setup Jenkins
    Launch an Amazon EC2 instance with Jenkins, Docker, Git, and other dependencies installed.

  2. Install Necessary Jenkins Plugins
    Add plugins for SonarQube Scanner, Node.js, Dependency Check, and Docker Pipeline.

  3. Configure SonarQube with Jenkins
    Set up SonarQube on Docker, create a security token, and integrate it with Jenkins for code analysis.

  4. Setup DockerHub Credentials
    Add DockerHub credentials in Jenkins to enable Docker image tagging and pushing.

  5. Create the Jenkins Job
    Define the Jenkins pipeline stages for cloning the repo, running SonarQube analysis, scanning with Trivy, and deploying with Docker.

Code Example
Here’s a snippet of the Jenkins pipeline configuration:

groovyCopy codepipeline {
    agent any
    stages {
        stage('Clone') { steps { git 'https://github.com/devops0014/Zomato-Project.git' } }
        stage('SonarQube Analysis') { ... }
        stage('Build Docker Image') { steps { sh 'docker build -t image1 .' } }
        stage('Trivy Scan') { steps { sh 'trivy image image1' } }
        stage('Deploy') { steps { sh 'docker run -d -p 1234:80 image1' } }
    }
}

Conclusion

Integrating these tools into a CI/CD pipeline enables continuous testing and security assessment, ensuring high-quality and secure releases. This project demonstrates a comprehensive approach to automating deployment and security within a DevOps workflow.
