SonarQube quick start with Docker

I strongly recommend using SonarQube to scan your code. Here is how to set it up locally.

1. Download and install Docker. (Docker is a container that allows developers to package up an application with all the parts it needs)
https://docs.docker.com/install/
2. Install SonarQube in docker and start the server
https://hub.docker.com/_/sonarqube/

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

3. Go to http://localhost:9000, login as admin (username: admin, password: admin)
4. Click 'create new project', follow the wizard, and note down the token (e.g. 15be81b4036cc5034363a43af4aa19773ea87242)
5. Run the maven command

mvn clean package sonar:sonar -Dsonar.projectKey=test -Dsonar.host.url=http://localhost:9000 -Dsonar.login=15be81b4036cc5034363a43af4aa19773ea87242

6. View the result at http://localhost:9000
