Truxnell's homelab

Leveraging nix, nix-os to apply machine and home configurations

Background

Having used a variety of infracture as code solutions - and having found them lacking in some areas, it is time to give nix a go. Frustrations with other methods tend to be bitrot and config drift - very annoying to want to do a quick disaster recovery and find your have different versions of modules/utilities, breaking changes in code you didnt catch, etc.

Getting started

To Install

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

Goals

• Learn nix
• Mostly reproduce features from my existing homelab
• Replace existing ubuntu-based 'NAS'
• Expand usage to other shell environments such as WSL, etc
• handle secrets - decide between sweet and simple SOPS or re-use my doppler setup.

TODO

• Github Actions update fly.io instances (Bitwarden)
• Bring over hosts
  • DNS01 Raspi4
  • DNS02 Raspi4
  • NAS
  • Latop
  • WSL
  • JJY emulator Raspi4
• Documentation!
• Add license
• Add taskfiles

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
