First, if you need to make this sort of change, it generally suggests that you need to rethink the architecture of your containers. Options to consider are (a) providing the file at build time via COPY comands in your Dockerfile, or (b) mounting a host directory into your container when you start it, and using that to transfer files in/out.

That said, you could probably arrange to use something like docker exec to get a file into a container:

docker exec -i mycontainer sh -c 'cat > /path/to/destination' < /path/to/source

Docker cp can be used to copy file from container to host, and host to container as well.

Conteiner to host: sudo docker cp da9230faeb38:/file ./

Host to container: sudo docker cp Desktop/file da9230faeb38:/
