No, not Proxmox on a RPi!
I’m using Proxmox as my main server on which I already run HA Core. (as it states in my sig)
This experiment on a RPi is a test to see if HA & UI can run (I guess it’s possible), and how with the different possibilites on 1 system, RPi with 7" official touchscreen attached to it.
To get familiar with docker, I am trying this out on my Proxmox server; this is much more flexible/easy to test with snapshots/clones and faster.
Hope it’s clear now.
