# My NixOS configurations
|
||||
|
||||
Here's my NixOS/home-manager config files. Requires [Nix flakes](https://nixos.wiki/wiki/Flakes).
|
||||
|
||||
**Highlights**:
|
||||
|
||||
- Multiple **NixOS configurations**, including **desktop**, **laptop**, **server**
|
||||
- **Opt-in persistence** through impermanence + blank snapshotting
|
||||
- **Encrypted** single **BTRFS** partition
|
||||
- Fully **declarative** **self-hosted** stuff
|
||||
- Deployment **secrets** using **sops-nix**
|
||||
- **Mesh networked** hosts with **tailscale** and **headscale**
|
||||
- Flexible **Home Manager** Configs through **feature flags**
|
||||
- Extensively configured wayland environments (**sway** and **hyprland**) and editor (**neovim**)
|
||||
- **Declarative** **themes** and **wallpapers** with **nix-colors**
|
||||
- **Hydra CI/CD server and binary cache** that uses the **desktops as remote builders**
|
||||
|
||||
## Structure
|
||||
|
||||
- `flake.nix`: Entrypoint for hosts and home configurations. Also exposes a
|
||||
devshell for boostrapping (`nix develop` or `nix-shell`).
|
||||
- `lib`: A few lib functions for making my flake cleaner
|
||||
- `hosts`: NixOS Configurations, accessible via `nixos-rebuild --flake`.
|
||||
- `common`: Shared configurations consumed by the machine-specific ones.
|
||||
- `global`: Configurations that are globally applied to all my machines.
|
||||
- `optional`: Opt-in configurations my machines can use.
|
||||
- `loki`: Lenovo ThinkPad X1 Carbon Extreme Gen 5
|
||||
- `home`: My Home-manager configuration, acessible via `home-manager --flake`
|
||||
- Each directory here is a "feature" each hm configuration can toggle, thus
|
||||
customizing my setup for each machine (be it a server, desktop, laptop,
|
||||
anything really).
|
||||
- `modules`: A few actual modules (with options) I haven't upstreamed yet.
|
||||
- `overlay`: Patches and version overrides for some packages. Accessible via
|
||||
`nix build`.
|
||||
- `pkgs`: My custom packages. Also accessible via `nix build`. You can compose
|
||||
these into your own configuration by using my flake's overlay, or consume them through NUR.
|
||||
- `templates`: A couple project templates for different languages. Accessible
|
||||
via `nix init`.
|
||||
|
||||
|
||||
## About the installation
|
||||
|
||||
All my computers use a single btrfs (encrypted on all except headless systems)
|
||||
partition, with subvolumes for `/nix`, a `/persist` directory (which I opt in
|
||||
using `impermanence`), swap file, and a root subvolume (cleared on every boot).
|
||||
|
||||
Home-manager is used in a standalone way, and because of opt-in persistence is
|
||||
activated on every boot with `loginShellInit`.
|
||||
|
||||
|
||||
## How to bootstrap
|
||||
|
||||
All you need is nix (any version). Run:
|
||||
```
|
||||
nix-shell
|
||||
```
|
||||
|
||||
If you already have nix 2.4+, git, and have already enabled `flakes` and
|
||||
`nix-command`, you can also use the non-legacy command:
|
||||
```
|
||||
nix develop
|
||||
```
|
||||
|
||||
`nixos-rebuild --flake .` To build system configurations
|
||||
|
||||
`home-manager --flake .` To build user configurations
|
||||
|
||||
`nix build` (or shell or run) To build and use packages
|
||||
|
||||
`sops` To manage secrets
|
||||
|
||||
|
||||
## Secrets
|
||||
|
||||
For deployment secrets (such as user passwords and server service secrets), I'm
|
||||
using the awesome [`sops-nix`](https://github.com/Mic92/sops-nix). All secrets
|
||||
are encrypted with my personal PGP key (stored on a YubiKey), as well as the
|
||||
relevant systems's SSH host keys.
|
||||
|
||||
On my desktop and laptop, I use `pass` for managing passwords, which are
|
||||
encrypted using (you bet) my PGP key. This same key is also used for mail
|
||||
signing, as well as for SSH'ing around.
|
||||
|
||||
