Server nixos configuration

This is the configuration running on my homebrew server. It is perfect in and no other config is in any way shape or form better.

How to Install

Prepare device

Install the nixos boot ISO and run it on your device. Once booted run

$ sudo passwd
$ ip a

to set a password for the nix user and display your ip. Once done you can ssh into the device and generate a nix hardware config with

$ ssh nix@<ip>
$ sudo mkdir /mnt
$ sudo nixos-generate-config --root /mnt --no-filesystem

This will generate the file /mnt/hardware-config.nix that you can then copy to your computer.

Install configuration

Prepare repo

1. Clone the repo
2. Copy the hardware-config.nix from your device to the repo folder.
3. Add/change the device configuration in flake.nix

Install remotely

Run the command

nix run github:nix-community/nixos-anywhere -- --flake '.#<your configuration>' --target-host nixos@<ip>

This will automatically install the configuration to your server.

Copy configuration to server

Once the configuration has been installed push your modified repo to a git service and pull it on the server.
