Hi. Since yesterday i selfhosted all my stuff with a raspberry pi and two odroids. Everything works ok, but after i read about a few apps that are not supported by the arm-architecture of the SBCs and about the advantages of the backup-solution in proxmox, i bought a little server (6500T/8GB/250GB) to try proxmox.
Installed proxmox, but now - before i install my first VM - i have a few questions:
a) What Linux OS do i take? Ubuntu Server?
b) Should it be headless?
The server is in the cellar of my house, so would there be any advantages of installing an OS with a GUI?
It's a bit like docker, in that it's a sort of isolated system, but you use it more like a virtual machine (VM). It's lighter than a VM because it uses the host kernel so you can run lots of them with out consuming too many resources.
In the Proxmox web interface, up in the top right corner there's a "Create CT" button. If you click through all that (once again I am recommending Ubuntu) you'll have your first LXC container up in a couple of minutes - the quick creating is another advantage over VM's. One of the joys of your excellent choice of Proxmox as a base is that you can easily experiment with such things.
