How to set up a NixOS server in UpCloud

This is not about Nix, but more of a tutorial on how I set up a server using UpCloud. I decided to document the steps I took to create a NixOS playground for myself.

Requirements

• UpCloud account
• SSH keys for secure access
• At least some Linux experience

Why UpCloud

Honestly, I just checked European Alternatives and chose UpCloud, because it’s Finnish.
