Usage

Initial Configuration

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

{
  shb.karakeep = {
    enable = true;
    domain = "example.com";
    subdomain = "karakeep";

    ssl = config.shb.certs.certs.letsencrypt.${domain};

    nextauthSecret.result = config.shb.sops.secret.nextauthSecret.result;

    sso = {
      enable = true;
      authEndpoint = "https://${config.shb.authelia.subdomain}.${config.shb.authelia.domain}";

      sharedSecret.result = config.shb.sops.secret.oidcSecret.result;
      sharedSecretForAuthelia.result = config.shb.sops.secret.oidcAutheliaSecret.result;
    };
  };

  shb.sops.secret.nextauthSecret.request = config.shb.karakeep.nextauthSecret.request;
  shb.sops.secret."karakeep/oidcSecret".request = config.shb.karakeep.sso.sharedSecret.request;
  shb.sops.secret."karakeep/oidcAutheliaSecret" = {
    request = config.shb.karakeep.sso.sharedSecretForAuthelia.request;
    settings.key = "karakeep/oidcSecret";
  };
}

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

The user and admin LDAP groups are created automatically.

Application Dashboard

Integration with the dashboard contract is provided by the dashboard option.

For example using the Homepage service:

{
  shb.homepage.servicesGroups.Documents.services.Karakeep = {
    sortOrder = 3;
    dashboard.request = config.shb.karakeep.dashboard.request;
  };
}

An API key can be set to show extra info:

{
  shb.homepage.servicesGroups.Documents.services.Karakeep = {
    apiKey.result = config.shb.sops.secret."karakeep/homepageApiKey".result;
  };

  shb.sops.secret."karakeep/homepageApiKey".request =
    config.shb.homepage.servicesGroups.Documents.services.Karakeep.apiKey.request;
}

Integration with Ollama

Assuming ollama is enabled, it will be available on port config.services.ollama.port. The following snippet sets up acceleration using an AMD (i)GPU and loads some models.

{
  services.ollama = {
    enable = true;

    # https://wiki.nixos.org/wiki/Ollama#AMD_GPU_with_open_source_driver
    acceleration = "rocm";

    # https://ollama.com/library
    loadModels = [
      "deepseek-r1:1.5b"
      "llama3.2:3b"
      "llava:7b"
      "mxbai-embed-large:335m"
      "nomic-embed-text:v1.5"
    ];
  };
}

Integrating with the ollama service is done with:

{
  services.open-webui = {
    environment.OLLAMA_BASE_URL = "http://127.0.0.1:${toString config.services.ollama.port}";
  };
}

Notice we're using the upstream service here services.open-webui, not shb.open-webui.
