* **默认情况下**，这意味着你**每个 IP 地址只能拥有一个 HTTPS 证书**。
     * 无论你的服务器有多大，或者服务器上的每个应用程序有多小。
     * 不过，对此有一个**解决方案**。
* **TLS** 协议（在 HTTP 之下的TCP 层处理加密的协议）有一个**扩展**，称为 **<a href="https://en.wikipedia.org/wiki/Server_Name_Indication" class="external-link" target="_blank"><abbr title="服务器名称指示">SNI</abbr></a>**。
     * SNI 扩展允许一台服务器（具有 **单个 IP 地址**）拥有 **多个 HTTPS 证书** 并提供 **多个 HTTPS 域名/应用程序**。

Então você poderá "servir" eles com o comando `serve`:

<div class="termy">

```console
// Use o comando "serve" após rodar "build-all"
$ python ./scripts/docs.py serve

Warning: this is a very simple server. For development, use mkdocs serve instead.
This is here only to preview a site with translations already built.
Make sure you run the build-all command first.

    * This was reported internally by [@rushilsrivastava](https://github.com/rushilsrivastava) as a memory leak when the server had unhandled exceptions that would produce internal server errors, the memory allocated before that point would not be released.

## Gunicorn과 함께하는 공식 도커 이미지 - Uvicorn

앞 챕터에서 자세하게 설명된 것 처럼, Uvicorn 워커와 같이 실행되는 Gunicorn을 포함하는 공식 도커 이미지가 있습니다: [서버 워커 - Uvicorn과 함께하는 Gunicorn](server-workers.md){.internal-link target=_blank}.

이 이미지는 주로 위에서 설명된 상황에서 유용할 것입니다: [다중 프로세스를 가지는 컨테이너와 특수한 경우들](#containers-with-multiple-processes-and-special-cases).

...wliczając w to `uvicorn`, który będzie służył jako serwer wykonujacy Twój kod.

!!! note
    Możesz również wykonać instalację "krok po kroku".

    Prawdopodobnie zechcesz to zrobić, kiedy będziesz wdrażać swoją aplikację w środowisku produkcyjnym:

    ```
    pip install fastapi
    ```

    Zainstaluj też `uvicorn`, który będzie służył jako serwer:

    ```
    pip install "uvicorn[standard]"
    ```
