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 use https://fedoraproject.org/coreos/ for my server/website. My host doesn't offer it as an image so I have to upload it myself, but I use an ISO I made with the CLI to automatically set up everything anyway. It works pretty well, I configured auto updates and I can just forget about it.
Thank you for the tip. Unless my understanding is wrong both OS are similar, Coreos targeting more precisely Kubernetes and cluster management. Had a quick look, but definitively will read more about it.
I will respond even though this post is several days old because I actually do this. I have some vpses on Hetzner that run Silverblue no problem. It is not an install option available by default there, but support uploaded an iso under my account quickly when asked.
If you do it, change the active firewalld zone. The default is for a desktop, so not great for vps space.
