nixos-configs

NixOS configurations for the machines I manage.

Currently managed systems:

• sue: My current laptop, a Dell XPS 9315. It has two flavours:
  • Default running GNOME
  • Specialisation running Cosmic
• gamepc: My gaming PC running Cinnamon
• warwick: A Raspberry Pi 4 Model B, which mostly does some monitoring
• atlas: A Gigabyte Brix, one of my Kubernetes nodes
• jefke: A Gigabyte Brix, one of my Kubernetes nodes
• lewis: A Gigabyte Brix, one of my Kubernetes nodes. Additionally, contains my media collection and does backups.

Deployment

I use Colmena for deploying my machines.

Create garbage collection roots like so:

colmena build --keep-result --experimental-flake-eval

To apply to the local machine:

sudo colmena apply-local --sudo --experimental-flake-eval

To apply to all remotely managed systems:

colmena apply --experimental-flake-eval

Note

Currently the --experimental-flake-eval flag is necessary to properly use Colmena with flakes. See this PR.
