【问题描述】*：

使用/dm8/bin/dminit 创建新数据库实例失败

Dockerfile:

FROM dameng

USER 1000
WORKDIR /dm8/data
RUN /bin/bash -ic '/dm8/bin/dminit PAGE_SIZE=16 PATH=/dm8/data\
	            DB_NAME=test INSTANCE_NAME=test\
	            CHARSET=1'
CMD /dm8/bin/dmserver /dm8/data/joyoj/dm.ini

其中 dameng/image 是用以下命令生成：

docker import dm8_docker.tar dameng

运行 docker build . 命令后，报以下错误：

docker docker build .

其中的路径/dm8/data存在
/dm8/data/test不存在
