Settings containing secret data should be set to an
attribute set containing the attribute
<literal>_secret</literal> - a string pointing to a file
containing the value the option should be set to. See the
example in `services.glance.settings.pages` at the weather widget
attribute set with this format: `{ _secret = "/path/to/secret"; }`.
See the example in `services.glance.settings.pages` at the weather widget
with a location secret to get a better picture of this.
Alternatively, you can use a single file with environment variables,
see `services.glance.environmentFile`.
'';
};
environmentFile = mkOption {
type = types.nullOr types.path;
description =
let
singleQuotes = "''";
in
''
Path to an environment file as defined in {manpage}`systemd.exec(5)`.
See upstream documentation
<https://github.com/glanceapp/glance/blob/main/docs/configuration.md#environment-variables>.
Example content of the file:
```
TIMEZONE=Europe/Paris
```
Example `services.glance.settings.pages` configuration:
```nix
[
{
name = "Home";
columns = [
{
size = "full";
widgets = [
{
type = "clock";
timezone = "\''${TIMEZONE}";
label = "Local Time";
}
];
}
];
}
];
```
Note that when using Glance's `''${ENV_VAR}` syntax in Nix,
you need to escape it as follows: use `\''${ENV_VAR}` in `"` strings
and `${singleQuotes}''${ENV_VAR}` in `${singleQuotes}` strings.
Alternatively, you can put each secret in it's own file,
see `services.glance.settings`.
