- kube-apiserver: a new `--requestheader-uid-headers` flag allows configuring request header authentication to obtain the authenticating user's UID from the specified headers. The suggested value for the new option is `X-Remote-Uid`. When specified, the `kube-system/extension-apiserver-authentication` configmap will include the value in its `.data[requestheader-uid-headers]` field.

Sie können die erforderlichen Header in der Dokumentationsoberfläche unter `/docs` sehen:

## Zusätzliche Header verbieten { #forbid-extra-headers }

In einigen speziellen Anwendungsfällen (wahrscheinlich nicht sehr häufig) möchten Sie möglicherweise die **Header einschränken**, die Sie erhalten möchten.

Sie können Header-Parameter genauso definieren, wie Sie `Query`-, `Path`- und `Cookie`-Parameter definieren.

## `Header` importieren { #import-header }

Importieren Sie zuerst `Header`:

## `Header`-Parameter deklarieren { #declare-header-parameters }
