Sending files from one docker container to another

Question

As the title states. I am looking to send a file from container A to container B. Both containers are running on separate volumes and are on the same network. Is this possible without temporarily storing the file in the host file system?

I have been reading around and found this solution, however it requires that the file I wish to send is temporarily stored in the host

Container A has its own volume to which a file is written to. I want to get Container A to send this file to a volume to which Container B is attached. Container B then reads this file.

Thanks

If they are linux containers you can use scp

scp file [email protected]:/path
