            - name: cloudbeaver-config
              mountPath: /opt/cloudbeaver/conf/product.conf
              subPath: product.conf
            # - name: cloudbeaver-config
            #   mountPath: /opt/cloudbeaver/workspace/user-projects/admin.dbeaver/.dbeaver/data-sources.json

              mountPath: /opt/cloudbeaver/workspace/GlobalConfiguration/.dbeaver/data-sources.json
              subPath: global-data-sources.json

            - name: cloudbeaver-config

        - name: cloudbeaver-config
          configMap:
            name: cloudbeaver-config

但是当我尝试通过 UI 添加 MySQL 连接时，出现以下错误

根据您遇到的错误，这可能是身份验证问题。在本教程中”如何在 CloudBeaver 中创建数据库连接”，本教程首先测试了Cloudbeaver与数据库的连接。
