SonarQube Infrastructure Setup using AWS EC2 and PostgreSQL

Providing a project explanation or documentation for setting up SonarQube infrastructure on EC2, using PostgreSQL as a database, and integrating it with Jenkins to run sonar-scanner on multiple jobs as part of a Groovy pipeline is essential for clarity and future reference. Here's a sample project explanation:

Infrastructure Setup

EC2 Instance Setup

1. Launch an Amazon EC2 instance using the desired Amazon Machine Image (AMI) with necessary security group settings. Ensure that the instance has adequate resources (CPU, RAM, etc.) for SonarQube.

2. SSH into the EC2 instance and configure it according to the SonarQube installation requirements.

PostgreSQL Database Setup

1. Set up a PostgreSQL database on a separate EC2 instance or on a managed PostgreSQL service like Amazon RDS.

2. Create a dedicated database and user for SonarQube with appropriate permissions.

3. Update the SonarQube configuration to point to the PostgreSQL database.

SonarQube Installation

1. Download and install SonarQube on the EC2 instance.

2. Configure SonarQube settings, including database connection details, authentication, and security settings.

3. Start the SonarQube service and ensure it's running.

Jenkins Integration

Jenkins Installation

1. Install Jenkins on a separate EC2 instance or use an existing Jenkins installation.

2. Configure Jenkins to run as a service and access it via its web interface.

Jenkins Configuration

1. Install and configure necessary plugins for Jenkins, including Git, Pipeline, and others as needed.

2. Set up authentication and authorization settings for Jenkins.

Jenkins SonarQube Plugin

1. Install the SonarQube Scanner for Jenkins plugin in Jenkins.

2. Configure the SonarQube server URL and authentication token within Jenkins.

Pipeline Setup

Pipeline Definition (Jenkinsfile)

1. Define a Jenkins pipeline using a Jenkinsfile. This pipeline defines how code analysis using SonarScanner should be executed.

2. The Jenkinsfile should specify the Git repository, branch, and the build steps including sonar-scanner execution.

Triggering Code Analysis

1. Create multiple Jenkins jobs or pipeline stages for different projects or branches.

2. Configure these jobs to execute the Jenkins pipeline, which in turn triggers the sonar-scanner for code analysis.

3. Set up triggers or schedules to periodically run code analysis jobs or integrate them into your CI/CD workflow.

Conclusion

This project provides a comprehensive setup for SonarQube infrastructure on EC2, integrates it with PostgreSQL as a database, and uses Jenkins to automate code quality analysis. By following the steps outlined in this documentation, you can maintain code quality and ensure continuous improvement in your software development process.
