This is an interesting topic; both raw docker and kubernetes lack dependency mechanisms. I think down the line, kubernetes is going to have to grow this to some degree. Currently one can basically just do retry/backoff loops in applications. > Is nulecule the way to do it?

We don't have a best practice around this yet that I'm aware of, but I would approach it with systemd units whose ExecStart=docker run. (Or if you want in the future, drop to runc, or use systemd-nspawn) I think you could indeed use nulecule to handle pulling multiple images and generating unit files to install them.
