I may get 2 unused devices (previous firewalls) using Rangeley or Denverton. I am thinking how do I use these devices baremetal? My only expierience using Docker is running it off Unraid, and it's been pretty easy. Is there a way to get Docker running in these low powered devices? Preferably without installing a full blown OS. Since my only exposure is through Unraid, and everything's in web interface, I'd like to have the same convenience if possible.
