Adding Secrets with sops-nix

Secrets are stored in configs/secrets/secrets.yaml. You can edit these secrets with sops secrets.yaml given you have an age private key stored at ~/.config/sops/age/keys.txt.

To decrypt these secrets with sops-nix during a rebuild, you must add your host public key to the .sops.yaml file. Generate it with cat /etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age, add it to the file, then run sops updatekeys secrets.yaml.

Provisioning A New Machine

On the target system, boot into the NixOS installer and run:

# Create a password for the nixos user for SSH access.
passwd

# Start wpa_supplicant and connect to a wifi network.
sudo systemctl start wpa_supplicant
wpa_cli
> add_network
> set_network 0 ssid "SSID"
> set_network 0 psk "password"
> enable_network 0
> quit

# Get the IP address of the target system.
ip addr

On the host machine, run the command deploy --flake .#<hostname> --target-host <username>@<ip_address> to build the new system configuration and copy it over SSH along with the sops age key and ssh keys.
