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.
