Kubernetes佈署SonarQube檢查Java項目代碼質量

在上一篇教程中，使用Docker快速佈署了SonarQube。這次將其佈署到kubernetes集群中

佈署Postgresql

SonarQube在未來將不支持Mysql，而內置H2數據庫只供測試使用。如果我們要正式佈署使用SonarQube，則需要佈署Postgresql。

佈署SonarQube服務

重要： SonarQube官方鏡像在配置文件中配置使用Postgresql無效（？可能是我方法不對）

查看官方鏡像啟動腳本

需要設置三個環境變量

1. SONARQUBE_JDBC_USERNAME
2. SONARQUBE_JDBC_PASSWORD
3. SONARQUBE_JDBC_URL
