jalr's NixOS Configuration

Install a new host

This installs nixos on host somehost:

NixOS Anywhere

nix run github:nix-community/nixos-anywhere -- --flake .#<somehost> root@<somehost>

The traditional way

nix-shell -p nixUnstable --run 'nixos-install --flake https://gitlab.jalr.de/jalr/nixos-configuration#somehost --no-channel-copy'

Build a configuration

nix build .#nixosConfigurations.iron.config.system.build.toplevel

setting up sops

Get the host key and convert it.

ssh-keyscan -t ed25519 $host | ssh-to-age

Then add the key to .sops.yaml

If the key changed, you might want to run

sops updatekeys hosts/$host/secrets.yaml

nix repl

$ nix repl

nix-repl> a=builtins.getFlake (toString ./.)

$ nix repl

nix-repl> :lf .#

Import GPG public key

gpg --card-edit
gpg/card> fetch
gpg --edit-key $key
gpg> trust
