Repository Documentation

Thank you Truxnell

Thank you for a lot of the groundwork you laid for the base nixos configuration and a lot of modules!

Getting started

To Install

nixos-rebuild switch --flake github:jahanson/nix-config-tn#HOST

Goals

  • Learn nix
  • Services I want to separate from my kubernetes cluster I will use Nix.
  • Approval-based update automation for flakes.
  • Expand usage to other shell environments such as WSL, etc
  • keep it simple, use trusted boring tools

TODO

  • Forgejo Actions
  • Bring over hosts
    • git.hsn.dev
    • Telperion (network services)
    • Gandalf (NixNAS)
    • Thinkpad T470

Checklist

Adding a new node

  • Ensure secrets are grabbed from note and all sops re-encrypte with task sops:re-encrypt
  • Add to relevant github action workflows
  • Add to .github/settings.yaml for PR checks

Applying configuration changes on a local machine can be done as follows:

cd ~/dotfiles
sudo nixos-rebuild switch --flake .
# This will automatically pick the configuration name based on the hostname

Applying configuration changes to a remote machine can be done as follows:

cd ~/dotfiles
nixos-rebuild switch --flake .#nameOfMachine --target-host machineToSshInto --use-remote-sudo

Hacking at nix files

Eval config to see what keys are being set.

nix eval .#nixosConfigurations.rickenbacker.config.security.sudo.WheelNeedsPassword
nix eval .#nixosConfigurations.rickenbacker.config.mySystem.security.wheelNeedsPassword

And browsing whats at a certain level in options - or just use nix-inspect TUI

nix eval .#nixosConfigurations.rickenbacker.config.home-manager.users.jahanson --apply builtins.attrNames --json

Quickly run a flake to see what the next error message is as you hack.

nixos-rebuild dry-run --flake . --fast --impure
