This has two implementations:
* The Credentials controller is responsible for reading TLS certificates, stored as Secrets.
* The Kubernetes Service Discovery controller is a bit of a monolith, and spins off a bunch of other sub-controllers in addition to the core service discovery controller.

Because of the monolithic complexity it helps to see this magnified a bit:

## Mounten einer Unteranwendung

Wenn Sie gleichzeitig eine Unteranwendung mounten (wie beschrieben in [Unteranwendungen – Mounts](sub-applications.md){.internal-link target=_blank}) und einen Proxy mit `root_path` verwenden wollen, können Sie das normal tun, wie Sie es erwarten würden.

```Python hl_lines="9"
{!../../docs_src/behind_a_proxy/tutorial004.py!}
```

这样，就不会在 OpenAPI 概图中包含服务器了。

## 挂载子应用

如需挂载子应用（详见 [子应用 - 挂载](sub-applications.md){.internal-link target=_blank}），也要通过 `root_path` 使用代理，这与正常应用一样，别无二致。
