I am copying data to a (gasp) docker volume each time I run a container as I want the latest data to be on the volume. The whole startup process is done in a Makefile (I know I should compose). Thing is with so many large files, it takes a while. Thats why I am asking if there is any way to make a rule that targets every file/subdirectory (it doesn't have to be recursive, but it would be neat if it were) in a directory in make.
