Options Reference

Defined in /modules/services/pinchflat.nix.

This NixOS module is a service that sets up a Pinchflat instance.

Compared to the stock module from nixpkgs, this one sets up, in a fully declarative manner, LDAP and SSO integration and has a nicer option for secrets.

Usage

The following snippet assumes a few blocks have been setup already:

shb.pinchflat = {
  enable = true;

  secretKeyBase.result = config.shb.sops.secret."pinchflat/secretKeyBase".result;
  timeZone = "Europe/Brussels";
  mediaDir = "/srv/pinchflat";

  domain = "example.com";
  subdomain = "pinchflat";
  ssl = config.shb.certs.certs.letsencrypt.${domain};

  ldap = {
    enable = true;
  };
  sso = {
    enable = true;
    authEndpoint = "https://${config.shb.authelia.subdomain}.${config.shb.authelia.domain}";
  };
};
shb.sops.secret."pinchflat/secretKeyBase".request = config.shb.pinchflat.secretKeyBase.request;

Secrets can be randomly generated with nix run nixpkgs#openssl -- rand -hex 64.

The user LDAP group is created automatically.

Backup

Backing up Pinchflat using the Restic block is done like so:

shb.restic.instances."pinchflat" = {
  request = config.shb.pinchflat.backup;
  settings = {
    enable = true;
  };
};

The name "pinchflat" in the instances can be anything. The config.shb.pinchflat.backup option provides what directories to backup. You can define any number of Restic instances to backup Pinchflat multiple times.
