Docker: adding a file from a parent directory

You can build the Dockerfile from the parent directory:

docker build -t <some tag> -f <dir/dir/Dockerfile> .

With docker-compose, you could set context folder:

#docker-compose.yml
version: 3.3    
services:
      yourservice:
        build:
          context: ./
          dockerfile: ./docker/yourservice/Dockerfile

Docker: adding a file from a parent directory

Unfortunately, (for practical and security reasons I guess), if you want to add/copy local content, it must be located under 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: Theres now an option (-f) to set the path of your Dockerfile ; it can be used to achieve what you want, see @Boedy s response.
