windows 下 dokcer build 后出现权限设置问题
这个权限是指哪个目录，然后怎么设置?
SECURITY WARNING: You are building a Docker image from Windows against a non-Windows Docker host. All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories.
windows本身是通过安装Linux虚拟机来支持Docker容器化解决方案的，这些的权限指的是我们创建的虚拟主机的目录权限。
//如果我们的虚拟名为default,进入之后用chmod命令对相应的目录进行权限操作
