You’ll need to create a compound file with all the images. The Docker images include the linux tar command, so that’s the easiest way. You may end up with a tar file that’s too large to download in one shot, so you might also need the linux split command. The easiest way is either to add a new cell in the notebook and use “bang escapes” to execute shell commands as in:
!ls -ltr
Or you can click “File → Open” and then “New → Terminal” and that gives you a linux shell.
