## Hosts
|
|
|
|
|
Module declarations dependant on particular machines should be stored in the
|
|
|
|
|
[hosts](hosts) directory. Every file in this directory will be added automatically
|
|
|
|
|
to the the `nixosConfigurations` flake output and thus becomes deployable via
|
|
|
|
|
`nixos-rebuild` and `rebuild`.
|
|
|
|
|
|
|
|
|
|
See [`hosts/default.nix`](hosts/default.nix) for the implementation.
|
|
|
|
|
|
|
|
|
|
## Profiles
|
|
|
|
|
A profile is any directory under [profiles](profiles) containing a `default.nix`
|
|
|
|
|
defining a valid NixOS module, with the added restriction that no new
|
|
|
|
|
delclarations to the `options` _or_ `config` attributes are allowed
|
|
|
|
|
(use [modules](modules) instead). Their purpose is to provide abstract
|
|
|
|
|
expressions suitable for reuse by multiple deployments. They are perhaps _the_
|
|
|
|
|
key mechanism by which we keep this repo maintainable.
|
|
|
|
|
|
|
|
|
|
Profiles can have subprofiles which are themselves just profiles that live under
|
|
|
|
|
another. There's no hard rule that everything in the folder must be imported by
|
|
|
|
|
its `default.nix`, so you can also store relevant code that is useful but not
|
|
|
|
|
wanted by default in, say, an `alt.nix`. Importantly, every subdirectory in a
|
|
|
|
|
profile should be independent of its parent. i.e:
|
|
|
|
|
|
|
|
|
|
```nix
|
|
|
|
|
{
|
|
|
|
|
# importing `profile` without implicitly importing `some`
|
|
|
|
|
imports = [ ./profiles/some/profile ];
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
It is okay for profiles to depend on other profiles so long as they are
|
|
|
|
|
explicitly loaded via `imports`.
|
|
|
|
|
|
|
|
|
|
Optionally, you may choose to export your profiles via the flake output. If
|
|
|
|
|
you include it in the list defined in [profiles/list.nix](profiles/list.nix),
|
|
|
|
|
it will be available to other flakes via `nixosModules.profiles`.
|
|
|
|
|
|
|
|
|
|
## Users
|
|
|
|
|
User declarations belong in the `users` directory.
|
|
|
|
|
|
|
|
|
|
These are actually just a special case of [profiles](#profiles) attached to
|
|
|
|
|
a particular interactive user. Its primarily for declarations to
|
|
|
|
|
`users.users.<new-user>` where `<new-user>.isNormalUser` is true.
|
|
|
|
|
|
|
|
|
|
This is a convenient place to import your profiles such that a particular user
|
2020-08-02 22:10:53 +00:00
|
|
|
always has a reliable stack. Also [user profiles](./users/profiles) are
|
|
|
|
|
available to create reusable configs across different users.
|
2020-01-11 06:49:18 +00:00
|
|
|
|
|
|
|
|
For convenience, [home-manager][home-manager] is available automatically for
|
|
|
|
|
home directory setup and should only be used from this directory.
|
|
|
|
|
|
|
|
|
|
## Secrets
|
|
|
|
|
Anything you wish to keep encrypted goes in the `secrets` directory, which is
|
|
|
|
|
created on first entering a `nix-shell`.
|
|
|
|
|
|
|
|
|
|
Be sure to run `git crypt init`, before committing anything to this directory.
|
|
|
|
|
Be sure to check out git-crypt's [documentation](https://github.com/AGWA/git-crypt)
|
|
|
|
|
if your not familiar. The filter is already set up to encrypt everything in this
|
|
|
|
|
folder by default.
|
|
|
|
|
|
|
|
|
|
To keep [profiles](profiles) reusable across configurations, secrets should
|
|
|
|
|
only be imported from the `users` or [`hosts`](hosts) directory.

## Cachix
|
|
|
|
|
When using:
|
|
|
|
|
```
|
|
|
|
|
cachix use <your-cachix>
|
|
|
|
|
```
|
|
|
|
|
A file with be created in `/etc/nixos/cachix/your-cachix.nix`. Simply add this
|
|
|
|
|
file to git, and it will be exported so others can use your binary cache
|
|
|
|
|
directly from this flake via `nixosModules.cachix.<your-cachix>`.

## Modules, Packages and Overlays
|
|
|
|
|
All expressions in both [modules/list.nix](modules/list.nix) and
|
|
|
|
|
[pkgs/default.nix](pkgs/default.nix) are available globally, anywhere else in the
|
|
|
|
|
repo. They are additionally included in the `nixosModules` and `overlay` flake
|
|
|
|
|
outputs, respectively. Packages can manually be added to [flake.nix](flake.nix)
|
|
|
|
|
for inclusion in the `packages` output as well.
|
|
|
|
|
|
|
|
|
|
The directory structure is identical to nixpkgs to provide a kind of staging area
|
|
|
|
|
for any modules or packages we might be wanting to merge there later. If your not
|
|
|
|
|
familiar or can't be bothered, simply dropping a valid nix file and pointing the
|
|
|
|
|
`default.nix` to it, is all that's really required.
|
|
|
|
|
|
|
|
|
|
As for overlays, they should be defined in the [overlays](overlays) directory.
|
|
|
|
|
They will be automatically pulled in for use by all configurations. Nix command
|
|
|
|
|
line tools will be able to read overlays from here as well since it is set as
|
|
|
|
|
`nixpkgs-overlays` in `NIX_PATH`. And of course they will be exported via the
|
|
|
|
|
flake output `overlays` as well.
