Mastering Sonar Scan Through Docker

SonarQube stands tall as an indispensable tool for ensuring code quality in software development. Leveraging its capabilities through Docker simplifies the setup process, enabling a seamless integration into your project workflow. By following a few straightforward steps, you can effortlessly deploy and harness the power of SonarQube within a Docker container.

Let's dive into the process together!

Step 1:

Setup SonarQube Docker

  • Pull SonarQube Docker Image if not present
$ sudo docker pull sonarqube

$ sudo docker pull sonarsource/sonar-scanner-cli:latest

$ sudo docker run -d --name sonarqube -p 9000:9000 -p 9092:9092 sonarqube

  • Note: To check SonarQube Docker Container logs, you can run below command.

$ sudo docker logs -f sonarqube

Step 2:

Access SonarQube Web Interface Open your web browser and navigate to http://localhost:9000. The default credentials (username / password) are: admin / admin

Step 4:

Generate Tokens for Local Project After setting up the project, you'll be prompted to generate a token. Enter a name for the token and click on the "Generate" button. Note down the generated token. This token is needed for authentication during the analysis.

Step 5:

Set Up Your React-Node Project Navigate to your project directory and create a sonar-project.properties.

Note: Project key and sonar token are necessary. See below example for file contents:

Step 6:

Run Sonar Scan Through Docker Image

  • Get Your IP Address
$ hostname -I | awk '{print $1}'
  • Run Sonar Scan
$ sudo docker run --rm --network=host -e SONAR_HOST_URL=
"http://<ip- address>:9000/" -e SONAR_TOKEN="<your-sonar-token>" 
-v $(pwd):/usr/src/ sonarsource/sonar-scanner-cli
  • Note: Replace < > with actual value.
