Configuration checks: Build Status

All Module options are documeted at: https://pinpox.github.io/nixos/

This repository includes all configurations for my NixOS machines. Feel free to use parts of it as you please, but keep it mind it is intended mostly for personal use. I've written posts about certain aspects of this setup on my personal blog.

Initial Setup

The structure of this repository is meant to allow easy manual deployment. Individual hosts are defined in /machines/<hostname> and will import re-usable parts of the configuration as needed.

Deployment is managed with lollypops Secrets are stored in pass.

TL;DR To use a host configuration on a fresh install, make sure that:

  • The hostname is set correctly (hostname <machine name>)
  • You are connected to the internet and have access rights to the repository
  • Pass has the necessary secrets for the machine
  • The machine's config is up-to-date

Then backup the generated hardware-configuration.nix file:

# Overwrite hardware-configuration.nix file with the generated one
cp /etc/nixos/hardware-configuration.nix \
   ./machines/$(hostname)/hardware-configuration.nix

# Commit and push the new file
git commit -am"Add hardware-configuration for $(hostname)" && git push

TODO: update

It is also possible to build on the system itself when logged in, e.g. to get additional debug information.

cd /var/src/machine-config
sudo nixos-rebuild --flake ".#kartoffel" switch

Current Hosts

Configuration Type Location VPN IP Description
kartoffel Desktop local 192.168.7.3 Desktop
ahorn Desktop local 192.168.7.2 Notebook
birne Server local 192.168.7.4 Local NAS
porree Server netcup.de 192.168.7.1 Server for pablo.tools
mega Server netcup.de 192.168.7.6 Server for megaclan3000.de
kfbox Server netcup.de 192.168.7.5 Server for 0cx.de

The services running on each host are documented in the host-specific README.md files.

Deployment

Default Deployment

Deployment is handled with lollypops.

TODO Update/document

First Deployment

If the system has not been configured to use flakes (e.g. fresh install), the first deployment will have to be build on a machine that has. This can be done from any of the other hosts that have the repository. The configuration will the have the necessary options set, so that flakes works from now on with the normal lollypops deployment.

# bash, zsh doesn't always work correctly
sudo nixos-rebuild --flake .#new-hostname --target-host <new-host-ip> --build-host localhost switch

Contributing?

While contributions don't make much sense for a personal configuration repository, I'm always happy to get hints, tips and constructive criticism. If you find something that could be done in a better way, please let me know!
