/// check | **FastAPI** рекомендует его как

Основной веб-сервер для запуска приложений **FastAPI**.

Также вы можете использовать опцию командной строки `--workers`, чтобы получить асинхронный многопроцессный сервер.

像 Kubernetes 这样的分布式容器管理系统通常有一些集成的方法来处理**容器的复制**，同时仍然支持传入请求的**负载均衡**。 全部都在**集群级别**。

在这些情况下，你可能希望从头开始构建一个 **Docker 镜像**，如[上面所解释](#dockerfile)的那样，安装依赖项并运行 **单个 Uvicorn 进程**，而不是运行 Gunicorn 和 Uvicorn workers这种。


### 负载均衡器

使用容器时，通常会有一些组件**监听主端口**。 它可能是处理 **HTTPS** 的 **TLS 终止代理** 或一些类似的工具的另一个容器。

由于该组件将接受请求的**负载**并（希望）以**平衡**的方式在worker之间分配该请求，因此它通常也称为**负载均衡器**。
