我在Windows 10上使用Docker创建pentaho和mysql映像,该映像将作为我使用docker网络创建定义的网络上的容器运行。我的意图是(作为第一步),我将运行一个带有pan.sh的.KTR文件,它将从一个.csv文件读取数据库连接参数,并将它们放入环境中;docker pentaho mysql驱动程序问题
Get the DB connection parameters
接下来的第二.KTR检查,看是否存在DB使用上述环境PARAMS;
问题是,当我为“正旋”我和泊坞窗,撰写项目,第二步失败,并没有发现问题的驱动器。我在pentaho容器的lib目录中放置了我需要的驱动程序,但我猜这是不正确的?
最终,其目的在于进行转换,其中通过pentaho中的一系列步骤处理从OpenEdge DB读取的数据,并将其写入mysql数据库。
这是支持文件; Dockerfile;

非常感谢。
P.S.有谁知道如何防止重建所有内容,即使它只是对dockerfile或入口点文件的小改动?
尝试将您的资源(C:\ Docker-Pentaho \ resource)移动到您的Windows用户主目录(C:/ Users ...),因为有关可能的挂载问题。另外,你的mysql默认侦听3306端口,只在docker-compose中改变它,没有任何意义(它仍然会听取3306) – Robert
感谢您花时间回复我的问题,但我想我有答案现在。 –
