Does anyone know of a hosting service that offers Silverblue as a possible choice for OS?
It seems to me that for a server running only docker services the greatly reduced attack surface of an immutable distro presents a definitive advantage.

I’m using NixOS in Azure - Azure allows creating a VM out of a disk image, and NixOS has tools to create preconfigured disk images. You inject your SSH keys and stuff straight into the image, then upload and create a VM. A bit fiddly, but I got it to work.
If you want MAC (SELinux or Apparmor) (which I highly recommend) then use Silverblue / CoreOS or even SUSE MicroOS
otherwise I use NixOS. (But like I said, I’m possibly looking into switching because of lacking MAC)
Thanks, good to know about firewall.
How would describe the “reduced attack surface” of something running a container?
That phrase has practically lost all meaning.
Because even if an attacker could gain access even as root he cannot modify system files. This is why immutable OS distros are called immutable.
