### SIG Multi-cluster (formerly known as SIG Federation)

[SIG Multi-cluster][] is responsible for infrastructure that supports
the efficient and reliable management of multiple Kubernetes clusters,
and applications that run in and across multiple clusters.

For the 1.8 release, SIG Multicluster focussed on expanding the set of
Kubernetes primitives that our Cluster Federation control plane

如果你使用容器（例如 Docker 或 Kubernetes），我會在下一章說明更多：[容器中的 FastAPI - Docker](docker.md)。

特別是，在 **Kubernetes** 上執行時，你多半會選擇不要使用 workers，而是每個容器只跑一個 **Uvicorn 單一處理序**。我會在該章節中進一步說明。

///

## 多個工作處理序 { #multiple-workers }

你可以用命令列選項 `--workers` 來啟動多個 workers：

//// tab | `fastapi`

如果你使用 `fastapi` 指令：

<div class="termy">

```console

`str | None` 并不是 FastAPI 用来判断是否必填的依据；是否必填由是否有默认值 `= None` 决定。

但添加这些类型注解可以让你的编辑器提供更好的支持并检测错误。

## 不使用 Pydantic { #without-pydantic }
