|
|
1. The system you want to deploy secrets to should already exist and
|
||
|
|
have `sshd` running on it so that it has generated SSH host keys in
|
||
|
|
`/etc/ssh/`.
|
||
|
|
|
||
|
|
2. Make a directory to store secrets and `secrets.nix` file for listing secrets and their public keys (This file is **not** imported into your NixOS configuration. It is only used for the `agenix` CLI.):
|
||
|
|
|
||
|
|
```ShellSession
|
||
|
|
$ mkdir secrets
|
||
|
|
$ cd secrets
|
||
|
|
$ touch secrets.nix
|
||
|
|
```
|
||
|
|
3. Add public keys to `secrets.nix` file (hint: use `ssh-keyscan` or GitHub (for example, https://github.com/ryantm.keys)):
|
||
|
|
```nix
|
||
|
|
let
|
||
|
|
user1 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIL0idNvgGiucWgup/mP78zyC23uFjYq0evcWdjGQUaBH";
|
||
|
|
user2 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILI6jSq53F/3hEmSs+oq9L4TwOo1PrDMAgcA1uo1CCV/";
|
||
|
|
users = [ user1 user2 ];
|
||
|
|
|
||
|
|
system1 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIPJDyIr/FSz1cJdcoW69R+NrWzwGK/+3gJpqD1t8L2zE";
|
||
|
|
system2 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIKzxQgondgEYcLpcPdJLrTdNgZ2gznOHCAxMdaceTUT1";
|
||
|
|
systems = [ system1 system2 ];
|
||
|
|
in
|
||
|
|
{
|
||
|
|
"secret1.age".publicKeys = [ user1 system1 ];
|
||
|
|
"secret2.age".publicKeys = users ++ systems;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
4. Edit secret files (these instructions assume your SSH private key is in ~/.ssh/):
|
||
|
|
```ShellSession
|
||
|
|
$ agenix -e secret1.age
|
||
|
|
```
|
||
|
|
5. Add secret to a NixOS module config:
|
||
|
|
```nix
|
||
|
|
{
|
||
|
|
age.secrets.secret1.file = ../secrets/secret1.age;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
6. Use the secret in your config:
|
||
|
|
```nix
|
||
|
|
{
|
||
|
|
users.users.user1 = {
|
||
|
|
isNormalUser = true;
|
||
|
|
passwordFile = config.age.secrets.secret1.path;
|
||
|
|
};
|
||
|
|
}
|
||
|
|
```
|
||
|
|
7. NixOS rebuild or use your deployment tool like usual.
|
||
|
|
|
||
|
|
The secret will be decrypted to the value of `config.age.secrets.secret1.path` (`/run/agenix/secret1` by default).
