# Configuration - How to configure clan with your own machines
|
|
|
|
## Global configuration
|
|
|
|
In the `flake.nix` file:
|
|
|
|
- [x] set a unique `clanName`.
|
|
- [ ] set `clanIcon` (optional)
|
|
- [ ] Set `machineIcon` per machine (optional)
|
|
|
|
These icons will be used by our future GUI.
|
|
|
|
=== "**buildClan**"
|
|
|
|
```nix title="clan-core.lib.buildClan"
|
|
buildClan {
|
|
# Set a unique name
|
|
clanName = "Lobsters";
|
|
# Optional, a path to an image file
|
|
clanIcon = ./path/to/file;
|
|
# Should usually point to the directory of flake.nix
|
|
directory = ./.;
|
|
|
|
machines = {
|
|
jon = {
|
|
# ...
|
|
# Optional, a path to an image file
|
|
clanCore.machineIcon = ./path/to/file;
|
|
};
|
|
# ...
|
|
}
|
|
}
|
|
```
|
|
|
|
=== "**flakeParts**"
|
|
|
|
!!! info "See [Clan with flake-parts](./flake-parts.md) for help migrating to flake-parts."
|
|
|
|
```nix title="clan-core.flakeModules.default"
|
|
clan = {
|
|
# Set a unique name
|
|
clanName = "Lobsters";
|
|
# Optional, a path to an image file
|
|
clanIcon = ./path/to/file;
|
|
|
|
machines = {
|
|
jon = {
|
|
# ...
|
|
# Optional, a path to an image file
|
|
clanCore.machineIcon = ./path/to/file;
|
|
};
|
|
# ...
|
|
}
|
|
};
|
|
```
|
|
|
|
## Machine configuration
|
|
|
|
Adding or configuring a new machine requires two simple steps:
|
|
|
|
### Step 1. Identify Target Disk-ID
|
|
|
|
1. Find the remote disk id by executing:
|
|
|
|
```bash title="setup computer"
|
|
ssh root@flash-installer.local lsblk --output NAME,ID-LINK,FSTYPE,SIZE,MOUNTPOINT
|
|
```
|
|
|
|
!!! Note
|
|
Replace `flash-installer.local` with the IP address of the machine if you don't have the avahi service running which resolves mDNS local domains.
|
|
|
|
Which should show something like:
|
|
|
|
```bash hl_lines="6"
|
|
NAME ID-LINK FSTYPE SIZE MOUNTPOINT
|
|
sda usb-ST_16GB_AA6271026J1000000509-0:0 14.9G
|
|
├─sda1 usb-ST_16GB_AA6271026J1000000509-0:0-part1 1M
|
|
├─sda2 usb-ST_16GB_AA6271026J1000000509-0:0-part2 vfat 100M /boot
|
|
└─sda3 usb-ST_16GB_AA6271026J1000000509-0:0-part3 ext4 2.9G /
|
|
nvme0n1 nvme-eui.e8238fa6bf530001001b448b4aec2929 476.9G
|
|
├─nvme0n1p1 nvme-eui.e8238fa6bf530001001b448b4aec2929-part1 vfat 512M
|
|
├─nvme0n1p2 nvme-eui.e8238fa6bf530001001b448b4aec2929-part2 ext4 459.6G
|
|
└─nvme0n1p3 nvme-eui.e8238fa6bf530001001b448b4aec2929-part3 swap 16.8G
|
|
```
|
|
|
|
1. Edit the following fields inside the `flake.nix`
|
|
|
|
=== "**buildClan**"
|
|
|
|
```nix title="clan-core.lib.buildClan" hl_lines="18 23"
|
|
buildClan {
|
|
# ...
|
|
machines = {
|
|
"jon" = {
|
|
imports = [
|
|
# ...
|
|
./modules/disko.nix
|
|
./machines/jon/configuration.nix
|
|
];
|
|
# ...
|
|
|
|
# Change this to the correct ip-address or hostname
|
|
# The hostname is the machine name by default
|
|
clan.networking.targetHost = pkgs.lib.mkDefault "root@jon"
|
|
|
|
# Change this to the ID-LINK of the desired disk shown by 'lsblk'
|
|
disko.devices.disk.main = {
|
|
device = "/dev/disk/by-id/__CHANGE_ME__";
|
|
}
|
|
|
|
# e.g. > cat ~/.ssh/id_ed25519.pub
|
|
users.users.root.openssh.authorizedKeys.keys = [
|
|
"<YOUR SSH_KEY>"
|
|
];
|
|
# ...
|
|
};
|
|
};
|
|
}
|
|
```
|
|
|
|
=== "**flakeParts**"
|
|
|
|
```nix title="clan-core.flakeModules.default" hl_lines="18 23"
|
|
clan = {
|
|
# ...
|
|
machines = {
|
|
"jon" = {
|
|
imports = [
|
|
# ...
|
|
./modules/disko.nix
|
|
./machines/jon/configuration.nix
|
|
];
|
|
# ...
|
|
|
|
# Change this to the correct ip-address or hostname
|
|
# The hostname is the machine name by default
|
|
clan.networking.targetHost = pkgs.lib.mkDefault "root@jon"
|
|
|
|
# Change this to the ID-LINK of the desired disk shown by 'lsblk'
|
|
disko.devices.disk.main = {
|
|
device = "/dev/disk/by-id/__CHANGE_ME__";
|
|
}
|
|
|
|
# e.g. > cat ~/.ssh/id_ed25519.pub
|
|
users.users.root.openssh.authorizedKeys.keys = [
|
|
"__YOUR_SSH_KEY__"
|
|
];
|
|
# ...
|
|
};
|
|
};
|
|
};
|
|
```
|
|
|
|
|
|
!!! Info "Replace `__CHANGE_ME__` with the appropriate identifier, such as `nvme-eui.e8238fa6bf530001001b448b4aec2929`"
|
|
!!! Info "Replace `__YOUR_SSH_KEY__` with your personal key, like `ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILoMI0NC5eT9pHlQExrvR5ASV3iW9+BXwhfchq0smXUJ jon@jon-desktop`"
|
|
|
|
These steps will allow you to update your machine later.
|
|
|
|
#### Step 2: Detect Drivers
|
|
Generate the `hardware-configuration.nix` file for your machine using the following command:
|
|
|
|
```bash
|
|
ssh root@flash-installer.local nixos-generate-config --no-filesystems --show-hardware-config > machines/jon/hardware-configuration.nix
|
|
```
|
|
|
|
#### Step 3: Custom Disk Formatting
|
|
In `./modules/disko.nix` a simple `ext4` disk partioning is defined for the disko module.
|
|
If you want a more complicated disk partioning setup look into the [disko examples](https://github.com/nix-community/disko/tree/master/example)
|
|
|
|
|
|
#### Step 4: Custom Configuration
|
|
In `./machines/jon/configuration.nix`, you can personalize the settings to suit your needs.
