"Dockerfile" or "dockerfile"?

General Discussions

I heard during a course that we must use the “Dockerfile” filename with an uppercase “D”.

I used “dockerfile” and I didn’t see any issues.

So what’s the deal?

Thanks

Yes, I am using Windows 7 but inside docker toolbox to interact with docker.

by default the name is with capital leading char
I don’t understand. What default? I am creating the file in my editor. There is no default.

yes, the toolbox window is on windows, not case sensitive
