nixos-config

Initial setup

1. Install NixOS using the official ISO
2. Generate an SSH key with ssh-keygen and save the public key in github
3. Start a nix shell with git in it

nix --extra-experimental-features 'nix-command flakes' shell nixpkgs#git

4. Clone this repo

git clone [email protected]:snyssen/nixos-config.git && cd nixos-config

5. Generate a new hardware-configuration.nix file for your host and add it to staged changes

nixos-generate-config --dir hosts/[host]/
git add hosts/[host]/hardware-configuration.nix

6. Switch to the host configuration

sudo nixos-rebuild switch --flake .#[host]

Commands

Tip

You can use the Nix Determinate installter to install nix on any Linux distro

Unlock secrets file (depends on having the GPG private key locally)

nix shell nixpkgs#git-crypt --command git-crypt unlock

Switch to specific config, e.g. gaming

sudo nixos-rebuild switch --flake .#gaming

[WIP] Deployment with nixos-anywhere

echo "my-super-safe-password" > /tmp/secret.key

nix run github:nix-community/nixos-anywhere -- --flake .#gaming --target-host [email protected] --generate-hardware-config nixos-generate-config ./hosts/gaming/hardware-configuration.nix --disk-encryption-keys /tmp/secret.key /tmp/secret.key
