# My NixOS configs
|
|
|
|
TODO: add directory structure info and enforce it
|
|
- every root folder in the repo represents a flake output except inputs
|
|
- every root folder only has a `default.nix` and subfolders for each
|
|
of its attrs
|
|
- in a subfolder, there should always be a `default.nix`
|
|
- if there is non nix code, it will be in a `config` folder
|
|
- redo docs
|
|
|
|
## AGS
|
|
|
|
You might find it weird that most of my config is written in TypeScript.
|
|
That's because all my desktops run
|
|
[AGS](https://github.com/Aylur/ags)
|
|
for UI. Click on
|
|
[this](https://git.nelim.org/matt1432/nixos-configs/src/branch/master/nixosModules/ags)
|
|
to see my configuration.
|
|
|
|
I'm also a victim of Stockholm syndrome at this point and make my scripts
|
|
in TypeScript because it's the scripting language I am most comfortable with.
|
|
|
|
## About
|
|
|
|
### General
|
|
|
|
This repo is the complete configuration of machines I own,
|
|
running NixOS or Nix. Its structure is based on a flake's
|
|
[outputs](https://wiki.nixos.org/wiki/Flakes#Output_schema).
|
|
|
|
### Flake Location
|
|
|
|
This git repo will always be located at `$FLAKE` (`config.environment.variables.FLAKE`)
|
|
and symlinked to `/etc/nixos` to have everything where NixOS tools
|
|
expect things to be.
|
|
|
|
ie.
|
|
|
|
```bash
|
|
sudo rm -r /etc/nixos
|
|
|
|
echo "$FLAKE" # /home/matt/.nix
|
|
|
|
sudo ln -sf /home/matt/.nix /etc/nixos
|
|
```
|
|
|
|
### Flake Outputs

|
|
| `packages` | Some custom [packages](https://git.nelim.org/matt1432/nixos-configs/src/branch/master/packages) not available in nixpkgs or modified from it |
|
|

|
|
| `devShells.default` | A dev shell to build an ISO from the live-image nixosConfiguration |

|
| `devShells.ags` | A dev shell to have a NodeJS env when I enter my AGS's config directory |
|
|
|
|
### Flake Inputs
|
|
|
|
To allow use of the full nix language for my inputs, I use [genflake](https://github.com/jorsn/flakegen).
|
|
Therefore, the flake I edit is located at `./outputs.nix`.
|
|
|
|
I also prefer using a more descriptive format for my inputs like so:
|
|
|
|
```nix
|
|
nixpkgs = {
|
|
type = "github";
|
|
owner = "NixOS";
|
|
repo = "nixpkgs";
|
|
|
|
# Branch name
|
|
ref = "nixos-unstable";
|
|
|
|
# Pin this input to a specific commit
|
|
rev = "842d9d80cfd4560648c785f8a4e6f3b096790e19";
|
|
};
|
|
```
|
|
|
|
to make it more clear what is what in the flake URI
|
|
|
|
### Secrets
|
|
|
|
All my secrets are in a private git repo that makes use of
|
|
[sops-nix](https://github.com/Mic92/sops-nix).
|
|
I generate `.sops.yaml` from `.sops.nix`:
|
|
|
|
```nix
|
|
let
|
|
wim = "somekey";
|
|
binto = "somekey2";
|
|
in {
|
|
creation_rules = [
|
|
{
|
|
path_regex = "secrets/[^/]+\\.(yaml|json|env|ini)$";
|
|
key_groups = [
|
|
{
|
|
age = [wim binto];
|
|
}
|
|
];
|
|
}
|
|
];
|
|
}
|
|
```
|
|
|
|
which is then converted to `.sops.yaml` using
|
|
[remarshal](https://github.com/remarshal-project/remarshal)
|
|
and this shell command:
|
|
|
|
```bash
|
|
nix eval --json --file ./.sops.nix | remarshal --if json --of yaml > .sops.yaml
|
|
```
|
|
|
|
