You’ll also need to import the modules in your host config (they aren’t wired in `flake.nix` yet), e.g.:
|
||
|
||
```nix
|
||
imports = [
|
||
./hardware-configuration.nix
|
||
../../modules/core
|
||
../../modules/networking
|
||
../../modules/virtualization
|
||
];
|
||
```
|
||
|
||
---
|
||
|
||
## `homelab.core`
|
||
|
||
Base system setup: kernel, bootloader, primary user, SSH, unfree packages.
|
||
|
||
| Option | Type | Default | Notes |
|
||
| --------------------- | ------------------------------------------------ | ---------------- | -------------------------------------------------------------------- |
|
||
| `kernel` | `"stable"` \| `"lts"` \| `"latest"` | `"lts"` | Maps to `linuxPackages`, `linuxPackages_lts`, `linuxPackages_latest` |
|
||
| |
|
||
| `user.name` | string | `"river"` | |
|
||
| `user.fullName` | string | `"Maaz Khokhar"` | |
|
||
| `user.shell` | string (typed as list in options — likely a bug) | `"fish"` | Used as `programs.${shell}.enable` |
|
||
| `allowUnfree` | bool | `true` | |
|
||
| `ssh.permitRootLogin` | bool | `false` | |
|
||
|
||
**Minimal core block:**
|
||
|
||
```nix
|
||
homelab.core = {
|
||
kernel = "lts";
|
||
# user / allowUnfree / ssh all have sensible defaults
|
||
};
|
||
```
|
||
|
||
**What you actually need to set:** bootloader details for your hardware (`grub.device` or `systemd.enable`). Everything else can stay default.
|
||
|
||
---
|
||
|
||
## `homelab.networking`
|
||
|
||
Split into `core` (always active when module is imported), `wireguard`, and `tailscale`.
|
||
|
||
### Top-level
|
||
|
||
| Option | Type | Default |
|
||
| ------ | ------ | --------- | --------------------------------- |
|
||
| `user` | string | `"river"` | Used by Tailscale as `--operator` |
|
||
|
||
### `homelab.networking.core` (always on)
|
||
|
||
| Option | Type | Default |
|
||
| -------------------- | ---------------------------------- | --------------------------------------- |
|
||
| `firewall.allowPing` | bool | `true` |
|
||
| `firewall.ports.tcp` | list of ints | `[ 22 80 ]` |
|
||
| `firewall.ports.udp` | list of ints | `[ 53 ]` |
|
||
| `extraHosts` | list of `{ ip_address, hostname }` | `[]` |
|
||
| `nameservers` | list of strings | `["192.168.1.193" "1.1.1.1" "1.0.0.1"]` |
|
||
|
||
**Required only when you add `extraHosts` entries:** `ip_address` and `hostname` (no defaults on those sub-options).
|
||
|
||
**Minimal core block:**
|
||
|
||
```nix
|
||
homelab.networking = {
|
||
core = {
|
||
nameservers = [ "1.1.1.1" "1.0.0.1" ];
|
||
# firewall defaults are usually fine
|
||
};
|
||
};
|
||
```
|
||
|
||
### `homelab.networking.wireguard` (optional)
|
||
|
||
| Option | Type | Default |
|
||
| ------------ | ---------------------------- | --------------------------------------------- |
|
||
| `enable` | bool | `false` |
|
||
| `interfaces` | attrset of interface configs | _(no default — use `{}` or omit if disabled)_ |
|
||
|
||
**Per interface** (`interfaces.<name>`):
|
||
|
||
| Option | Required? | Default |
|
||
| ---------------- | -------------------------------- | ------- |
|
||
| `enable` | no | `false` |
|
||
| `address` | no | `[]` |
|
||
| `privateKeyFile` | **yes** (when interface enabled) | — |
|
||
| `peers` | no | `[]` |
|
||
|
||
**Per peer:**
|
||
|
||
| Option | Required? | Default |
|
||
| --------------------- | --------- | ------- |
|
||
| `publicKey` | **yes** | — |
|
||
| `allowedIPs` | no | `[]` |
|
||
| `endpoint` | no | `""` |
|
||
| `persistentKeepalive` | no | `null` |
|
||
|
||
**Example when enabled:**
|
||
|
||
```nix
|
||
homelab.networking.wireguard = {
|
||
enable = true;
|
||
interfaces.wg0 = {
|
||
enable = true;
|
||
address = [ "10.0.0.2/24" ];
|
||
privateKeyFile = "/path/to/private.key";
|
||
peers = [{
|
||
publicKey = "...";
|
||
allowedIPs = [ "0.0.0.0/0" ];
|
||
endpoint = "vpn.example.com:51820";
|
||
}];
|
||
};
|
||
};
|
||
```
|
||
|
||
**Note:** `wireguard.nix` exists but is **not** imported in `modules/networking/default.nix` — only `core` and `tailscale` are. You’d need to add `./wireguard.nix` to that imports list for WireGuard to work.
|
||
|
||
### `homelab.networking.tailscale` (optional)
|
||
|
||
| Option | Type | Default |
|
||
| -------- | ---- | ------- |
|
||
| `enable` | bool | `false` |
|
||
|
||
**Minimal:**
|
||
|
||
```nix
|
||
homelab.networking.tailscale.enable = true;
|
||
# uses homelab.networking.user (default "river") as operator
|
||
```
|
||
|
||
---
|
||
|
||
## `homelab.virtualization`
|
||
|
||
Split into `podman` and `qemu`.
|
||
|
||
### Top-level
|
||
|
||
| Option | Type | Default |
|
||
| ------ | ------ | --------- | ----------------------------------------- |
|
||
| `user` | string | `"river"` | Added to `libvirtd`/`kvm`/`podman` groups |
|
||
|
||
### `homelab.virtualization.podman`
|
||
|
||
| Option | Type | Default |
|
||
| ----------------- | ---- | ------- | ----------------------------------------------------- |
|
||
| `enable` | bool | `false` |
|
||
| `packages.enable` | bool | `false` | Installs `podman`, `podman-compose`, `podman-desktop` |
|
||
|
||
**Minimal:**
|
||
|
||
```nix
|
||
homelab.virtualization.podman = {
|
||
enable = true;
|
||
packages.enable = true; # optional
|
||
};
|
||
```
|
||
|
||
### `homelab.virtualization.qemu`
|
||
|
||
| Option | Type | Default |
|
||
| --------------------- | --------------- | --------------------------- | ----------------------------------------------------------------------------------------------- |
|
||
| `enable` | bool | `false` |
|
||
| `containers.enable` | bool | `false` | _(defined in options but not wired in `qemu.nix` — containers are always enabled when qemu is)_ |
|
||
| `spiceUSBRedirection` | bool | `false` |
|
||
| `virtManager` | bool | `false` |
|
||
| `bootModules` | list of strings | `[ "kvm-intel" "kvm-amd" ]` |
|
||
|
||
**Minimal:**
|
||
|
||
```nix
|
||
homelab.virtualization.qemu = {
|
||
enable = true;
|
||
virtManager = true; # optional GUI
|
||
};
|
||
```
|
||
|
||
When `qemu.enable = true`, the module sets up `libvirtd`, adds your user to `libvirtd`/`kvm`, and loads KVM modules.
