SonarQube has its dedicated Helm chart which is perfect for us. However, it's the most resource hungry component of our development stack so far (because built with Java ? End of troll), so be sure to deploy it on almost empty free node (which should be ok with 3 workers), maybe a dedicated one. In fact, it's the last Helm chart for this tutorial, I promise!

Create dedicated database for SonarQube same as usual.

Be sure to disable the PostgreSQL sub chart and use our self-hosted cluster with both `postgresql.enabled` and `jdbcOverwrite.enabled`. If needed, set proper `tolerations` and `nodeSelector` for deploying on a dedicated node.

The installation take many minutes, be patient. Once done, you can access SonarQube on `https://sonarqube.kube.rocks` and login with `admin` / `admin`.
