To allow me to use my UNRAID server to upload data into databases I built a OpenJDK Java Docker. The Docker runs a script which executes a Java program. I am not sure if this how you are supposed to use Docker, but it works nicely for me.
I have the base components of my new UNRAID server. I got a Chinese X99 dual CPU motherboard off eBay, it’s the ZX-DU99D4 V1.11. Which I will be running two Xeon E5-2650LV3 with 64GB of Ram (both used of eBay). This will be a great base system for playing with VMs and dockers etc in UNRAID using the ZX-DU99D4, as well as running backups.
