Hello
Its always better to have packer clean, and you can use a shell script to
wrap pre-requirements
as packer usually check state before running, may/may not work in the way
you want.
There is a provisioner named shell-local you can use to run commands in the
host but its too late to import a docker image there.
if I try to docker pull an image, please notice it does happen after the
docker has been "started"
# packer build template.json
*xenial output will be in this color.*

So you are better having a shell script that does the import and then runs
packer.
