Unfortunately, (for practical and security reasons I guess), if you want to add/copy local content, it must be located und Er the same root path than the Dockerfile . From the Documentation: The <src> path must be inside the context of the build; You cannot ADD: /something/something, because the first step of a Docker build is to send the context directory (and subdirectories) To the Docker daemon. EDIT: There ' s now a option ( -f ) to set the path of your Dockerfile; it can is used to achieve what's want, see @Boedy ' s Response Nelow.

is there a "clean" Workar Ound for this? I ' d rather not restructure my whole project directory just to accommodate This. – ben_frankly nov" at 18:35 As said by @günter, there are a workaround here superuser.com/a/842690/136024 ... is it really "clean"? Well at least it ' s a "workaround":) –anthony O Dec 2 ' in 8:39 See better answer from @Boedy stackoverflow.com/a/34300129/2950621–nmgeek June at 19:27 Add a Comment

You can build the Dockerfile from the parent directory: docker build -t <some tag> -f <dir/dir/Dockerfile> . ShareImprove this answer answered Dec ' at 21:54boedy3885

Worked smoothly;) –souciance Eqdam Rashti Mar 2 at 10:51 Thank you! This works fine in a local box, but Docker Hub fails to build the image since it tries to does it from its same directory (t BH, just what one would normally expect). Is there any-to-do the same-trick in Docker Hub? –marcel Hernandez Mar at 20:31 Not that I know of. You could push the image to the registry instead of using automated build. –boedy Mar at 9:15 1 This should is marked as the right Answer–courtland Caldwell June at 19:09 Add a Comment

The solution for those who use composer are to use a volume pointing to the parent folder: #docker-composer.ymlfoo: build: foo volumes: - ./:/src/:ro But I ' m pretty sure the can is done playing with volumes in Dockerfile. ShareImprove this answer
