### Understanding the .clan-flake Marker File
The `.clan-flake` marker file serves an optional purpose: it helps the `clan-cli` utility locate the project's root directory.
If `.clan-flake` is missing, `clan-cli` will instead search for other indicators like `.git`, `.hg`, `.svn`, or `flake.nix` to identify the project root.
-`url`: Specifies the Git repository URL for Clan Core.
-`inputs.nixpkgs.follows`: Tells Nix to use the same `nixpkgs` input as your main input (in this case, it follows `nixpkgs`).
3.**Update Outputs**: Then modify the `outputs` section of your `flake.nix` to adapt to Clan Core's new provisioning method. The key changes are as follows:
- This command rebuilds and switches to the new configuration. Make sure to include the `--flake .` argument to use the current directory as the flake source.
5.**Test Configuration**: Before rebooting, verify that your new configuration builds without errors or warnings.
6.**Reboot**: If everything is fine, you can reboot your system to apply the changes:
7.**Verify**: After the reboot, confirm that your system is running with the new configuration, and all services and applications are functioning as expected.
By following these steps, you've successfully migrated your NixOS Flake configuration to include the `clan-core` input and adapted the `outputs` section to work with Clan Core's new machine provisioning method.
Clan supports integration with the Nix ecosystem through its flake module, making it compatible with [flake.parts](https://flake.parts/),
a tool for modular Nix flakes composition.
Here's how to set up Clan using flakes and flake-parts.
### 1. Update Your Flake Inputs
To begin, you'll need to add `clan-core` as a new dependency in your flake's inputs. This is alongside the already existing dependencies, such as `flake-parts` and `nixpkgs`. Here's how you can update your `flake.nix` file:
After updating your flake inputs, the next step is to import the `clan-core` flake module into your project. This allows you to utilize Clan functionalities within your Nix project. Update your `flake.nix` file as shown below:
```nix
outputs =
inputs@{ flake-parts, ... }:
flake-parts.lib.mkFlake { inherit inputs; } (
{
imports = [
inputs.clan-core.flakeModules.default
];
}
);
```
### 3. Configure Clan Settings and Define Machines
Lastly, define your Clan configuration settings, including a unique clan name and the machines you want to manage with Clan.
This is where you specify the characteristics of each machine,
such as the platform and specific Nix configurations. Update your `flake.nix` like this:
```nix
outputs =
inputs@{ flake-parts, ... }:
flake-parts.lib.mkFlake { inherit inputs; } (
{
imports = [
inputs.clan-core.flakeModules.default
];
clan = {
clanName = "NEEDS_TO_BE_UNIQUE"; # Please replace this with a unique name for your clan.
directory = inputs.self;
machines = {
example-desktop = {
nixpkgs.hostPlatform = "x86_64-linux";
imports = [ ./configuration.nix ];
};
};
};
}
);
```
For detailed information about configuring `flake-parts` and the available options within Clan,
