In the previous blog post, we completed the Sonarqube deployment through Kubernetes's devlopment and service. Seems to be available, but there is still a big problem. We know that databases like MySQL need to keep data and not lose data. And the container is exactly the moment you exit, all data is lost. Once our Mysql-sonar container is restarted, any subsequent settings we make to Sonarqube will be lost.

[TOC]Brief introductionIn many scenarios, the following initialization is required before the application starts:
Wait for other associated components to run correctly (for example, a database or a background service)
Generate a configuration file based on an environment variable or a configuration template
Get the local desired configuration from the remote database, or register itself in a central database
Download the dependent packages or perform some pre-configuration a
