So I have docker-in-docker running as a sidecar in a pod with /var/lib/docker pointed to emptyDir: {}.

I need to load a couple of images into it after it comes up to have it work as I need it to. I can docker save them from my repo and move them to storage on the node without too much angst.

Is there a simple, accepted way pull them in or do I need to experiment with another container with docker-cmds and scripting something?
