# 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:
|
|
|
|
```bash
|
|
# 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 following command to build the new system configuration and copy it over SSH along with the sops age key and ssh keys.
|
|
|
|
```bash
|
|
# WARNING: You must use the IP address of the machine.
|
|
# The hostname will not suffice as it will boot into a NixOS installer through kexec.
|
|
deploy --flake .#<hostname> --target-host <username>@<ip_address>
|
|
```
|
|
|
|
Complete the setup by running the following on the target system once it is booted into the new install.
|
|
|
|
```bash
|
|
# On the target machine:
|
|
sudo rm /etc/ssh/ssh_host_*
|
|
sudo ssh-keygen -A
|
|
cat /etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age
|
|
|
|
# On the host machine:
|
|
# Add the host age public key to .sops.yaml
|
|
sops updatekeys secrets.yaml
|
|
|
|
```
