A security alert appears when you build a Docker image on a non-Windows Docker host in docker

Using the Dockertoolbox, Introduction to Docker 5~Use Dockerfile~[For beginners]

In , I created and built dockerfile.

It seems that the blogger created a directory called docker in the mac version ~/Desktop and created dockerfile there.Since I use dockertoolbox in Windows, I tried to proceed with the default directory as much as possible, but when I tried mkdir docker under the default /c/Program Files/Docker Toolbox, I got a permission error.

So I was worried, but I created a docker directory under /c/Desktop, created a dockerfile, and when I did docker build, the following message came out:I understand that it seems to be a security issue, but is there no problem if I proceed as it is?Also, the default directory /c/Program Files/Docker Toolbox when you start Docker Quickstart Terminal is denied permission, and I'm wondering if I can change it badly.Should I be able to work under this directory?

You are building a Docker image from Windows again - Windows Docker host. All files and directors added to build context will have'-rwxr-xr-x'permissions.It is recommended to double check and reset permissions for sensitive files and directories.
