Integrating SonarQube into Your CI/CD Pipeline: Elevating Code Quality and Security

Adding Sonarqube into our workflow, code and security analysis.

Pre-requisites

• Read the 1st part
• Ngrok app

For clarification

I tried to install it on the t2.micro instance but Sonarqube requires 2 gb ram

We will install it on our local machine to do everything for free at least in this test environment, but in AWS a t2.medium is recommended (it is not free tier).

Deploy Sonarqube

• Sonarqube compose file
• cd /path(compose file)

docker-compose up -d

In sonarqube it is typical to find this error when deploying the container.

The solution is simple paste into the CLI the next code

sudo sysctl -w vm.max_map_count=262144

Opening Sonarqube Web -> http://localhost:9000

Well as sonarqube is in our localhost now we will expose it to the internet

• Tunneling app to internet through Ngrok

Our Sonarqube is now exposed to the internet

Configure Jenkins to add Sonarqube

1. Go to Jenkins -> Manage Jenkins -> Plugins ->Available plugins
2. Install SonarQube Scanner

Now we configure the plugin

1. Manage Jenkins -> System
2. Search SonarQube servers -> Click Environment variables

• Go to SonarQube Web
• Click in Administration bar -> Security-> Users

• Click Token and name it

Now copy the token into the jenkins configuration variable

• Press Add
• Kind= Secret text ID and description name them as you wish

• Change Server authentication token

• Save

CodeQuality Stage

Take a look to the pipeline project

tools: maven 3.9.6
Go to Manage Jenkins -> Tools -> Maven

Ready to run the job

• Build the job

1. New Item -> Pipeline

Check the correct branch

run

• Pulsa sobre el icono de sonarqube en la web, y haz click en el proyecto demo

Quality Gate

What is a quality gate for?
This function is used to wait for a certain time until the code analysis is completed
It's simple to use, just add the next code to the pipeline

stage("Quality Gate") {
      steps {
        timeout(time: 2, unit: 'MINUTES') {
          waitForQualityGate abortPipeline: true
        }
      }
    }
