More or less what we do in our installation notes here for "unattended" installations.

Why did you trigger a reboot?

@josegonzales yeah, that page is where I started from. :) I think the Docker .deb package suggests you to reboot but I will double check if it's really necessary.

A pretty cool thing is that I can run this script from Terraform and I get from zero to a running Dokku with a simple terraform apply. I was thinking of sharing the Terraform config as well, I just need to remove a few hardcoded values that are specific to my Amazon account.

The deb package is probably detecting that it needs to enable aufs, hence the reboot.
