Setting up qemu VM using nix flakes

Did you know that it is rather easy to setup a VM to test your NixOs configuration?

Create simple flake:

# flake.nix
{
  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";

Install a docker registry in a k3s kubernetes cluster

k3s doesn't have a builtin plugin for a local registry, so this is how to install the docker registry. The registry will be exposed via the default traefik ingress (on port 80 and 443).

Assumptions

• resolvectl query registry.localhost returns 127.0.0.1 - on most Linux distros it does. If not, enable and configure systemd-resolved
• K3s comes with traefik ingress controller by default, so the ingress for the registry service is configured for that.
