SonarQube is an open-source tool that helps developers continuously inspect the code quality of their projects. It provides code analysis, code coverage, and code duplication detection, along with various other features. With SonarQube, developers can easily detect and fix the technical debt, improving the quality of their code.

Prerequisites

  • Any basic programming language knowledge.
  • Basic OOPS concepts understanding


The article demonstrates SonarQube Analysis with C# programming language.

Learning Objectives

  • How to do SonarQube analysis via the Docker Image
  • How to analyze C# application via the Docker Image

Getting Started

Running SonarQube on a local machine can sometimes be cumbersome due to the complex setup requirements, but Docker can simplify the process. Docker is a platform for building, shipping, and running container applications. Docker provides an easy-to-use interface for managing and deploying applications and can be used to run SonarQube.


In this article, we will explore the steps to run SonarQube via the Docker image:

Step 1: Install Docker

The first step to running SonarQube via Docker is to install Docker on your machine. Docker provides installation instructions for different operating systems on their website.

Step 2: Pull the SonarQube Image

Once Docker is installed, the next step is to pull the SonarQube image from the Docker Hub. You can do this by running the following command in the terminal:

docker pull sonarqube

This command will download the latest SonarQube image from the Docker Hub.

Step 3: Run the SonarQube Container

Now that the SonarQube image has been downloaded, the next step is to run the SonarQube container. You can do this by running the following command in the terminal:

docker run -d --name sonarqube -p 9000:9000 sonarqube

This command will start the SonarQube container and expose port 9000 on the host machine. You can access the SonarQube web interface by opening a web browser and navigating to http://localhost:9000.

Step 4: Analyze Code with SonarQube

With the SonarQube container up and running, you can now analyze your code by following these steps:

  1. Generate a SonarQube analysis report for your codebase.
  2. Copy the report to the SonarQube container.
  3. Run the SonarQube analysis by executing the following command:
docker exec sonarqube /opt/sonar-scanner/bin/sonar-scanner \
   -Dsonar.projectKey=<project_key> \
   -Dsonar.sources=<path_to_code> \
   -Dsonar.host.url=http://localhost:9000 \
   -Dsonar.login=<token>

Analyze a C# application using SonarQube via the Docker image

Step 1: Add SonarQube Scanner for MSBuild to your project

The SonarScanner for MSBuild is a .NET Core tool that helps to integrate SonarQube analysis into the MSBuild process. You can add the SonarScanner for MSBuild to your project by running the following command in the terminal:

dotnet tool install --global dotnet-sonarscanner

Step 2: Generate a SonarQube Analysis Report

Once the SonarScanner for MSBuild is installed, the next step is to generate a SonarQube analysis report for your C# project. You can do this by running the following command in the terminal:

dotnet sonarscanner begin /k:"<project_key>" /d:sonar.host.url="http://localhost:9000" /d:sonar.login="<token>"

Replace <project_key> with a unique identifier for your project and <token> the authentication token for your SonarQube instance.

This command will begin the SonarQube analysis and generate a report for your C# project.

Step 3: Build your C# project

Next, build your C# project using the following command:

dotnet build

This command will compile your C# code and create a binary executable.

Step 4: Analyze your C# project with SonarQube

Once your C# project is built, you can analyze it with SonarQube by running the following command:

dotnet sonarscanner end /d:sonar.login="<token>"

This command will end the SonarQube analysis and upload the report to your SonarQube instance.

Step 5: View the SonarQube Analysis Results

Now that the analysis is complete, you can view the results in the SonarQube web interface by navigating to http://localhost:9000. In the SonarQube interface, you can see information about code quality, code coverage, and other metrics for your C# project.

Conclusion

That’s it! Following these steps, you can quickly analyze your C# application using SonarQube via the Docker image. SonarQube can help you identify code quality issues and improve the overall maintainability of your codebase.
