You can do it with a container:

docker run --rm -v `pwd`:/source -v some-volume:/target \
  busybox cp -av /source/somefile.txt /target/somefile.txt

I also use tar and stdin to connect files to a remote volume via a docker client / server connection:

tar -cv -C source-dir . | \
  docker run --rm -i -v some-volume:/target busybox tar -xC /target

The export is similar:

docker run --rm -v some-volume:/source busybox tar -cC /source . | \
  tar -xC target-dir
