chmod 600 ~/.ssh/*
chmod 644 ~/.ssh/*.pub
  1. Clone nix-config repo
nix-shell -p git
git clone git@github.com:andrewyazura/nix-config.git
  1. Copy new hardware-config.nix to hosts/yorhaXX/hardware-config.nix
  2. Apply config
sudo nixos-rebuild switch --flake .#yorha2b

sops

Converting keys
ssh-to-age -i ~/.ssh/id_ed25519_yorhaXX_nixconfig_XXXX.pub

ssh-to-age -i ~/.ssh/id_ed25519_yorhaXX_nixconfig_XXXX -private-key -o keys.txt
Updating secrets

Make sure:

  • public key is in .sops.yaml
  • private key is in ~/.config/sops/age/keys.txt

then run

sops updatekeys secrets/<secret_name>

yorhaA2

sudo darwin-rebuild switch

remote machines

nixos-rebuild --flake .#<machine> --target-host andrew@<machine> switch --sudo

using deploy-rs

same system:

nix run github:serokell/deploy-rs -- .#<machine>

different system:

nix run github:serokell/deploy-rs -- .#<machine> --remote-build
