+///
+/// The arguments are passed through to the `#[kube]` attribute. More details can be found in the
+/// official docs: <https://docs.rs/kube/latest/kube/derive.CustomResource.html>.
+///
+/// Supported arguments are:
+///
+/// - `group`: Set the group of the CR object, usually the domain of the company.
+///   This argument is Required.
+/// - `kind`: Override the kind field of the CR object. This defaults to the struct
+///    name (without the 'Spec' suffix).
+/// - `singular`: Set the singular name of the CR object.
+/// - `plural`: Set the plural name of the CR object.
+/// - `namespaced`: Indicate that this is a namespaced scoped resource rather than a
+///    cluster scoped resource.
+/// - `crates`: Override specific crates.
+/// - `status`: Set the specified struct as the status subresource.
+/// - `shortname`: Set a shortname for the CR object. This can be specified multiple
+///   times.
+/// - `skip`: Controls skipping parts of the generation.
