1. 將 `main.py` 直接複製到 `/code` 目錄（不需要 `./app` 目錄）。

2. 使用 `fastapi run` 來服務單檔的 `main.py` 應用。

當你把檔案傳給 `fastapi run`，它會自動偵測這是一個單一檔案而非套件的一部分，並知道如何匯入並服務你的 FastAPI 應用。😎

## 部署概念 { #deployment-concepts }

我們用容器的角度再談一次部分相同的[部署概念](concepts.md)。

容器主要是簡化應用「建置與部署」流程的工具，但它們不強制特定的方式來處理這些「部署概念」，而是有多種策略可選。

好消息是，每種不同的策略都能涵蓋所有部署概念。🎉

讓我們用容器的角度回顧這些部署概念：

* HTTPS
* 開機自動執行
* 失敗重啟
* 複本（執行的行程數量）
* 記憶體

#### StatefulSet
* [beta] StatefulSet supports [RollingUpdate](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#rolling-updates) and [OnDelete](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#on-delete) update strategies.

* データ変換
* データの検証
* 自動文書化

## 特殊な型とバリデーション { #special-types-and-validation }

`str`や`int`、`float`などの通常の単数型の他にも、`str`を継承したより複雑な単数型を使うこともできます。

すべてのオプションをみるには、[Pydantic の型の概要](https://docs.pydantic.dev/latest/concepts/types/)を確認してください。次の章でいくつかの例をみることができます。

例えば、`Image`モデルのように`url`フィールドがある場合、`str`の代わりにPydanticの`HttpUrl`のインスタンスとして宣言することができます:

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

  * [Nodes](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#node-affinity-beta-feature) and [pods](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#inter-pod-affinity-and-anti-affinity-beta-feature) now support affinity and anti-affinity
  * Advanced scheduling can be performed with [taints and tolerations](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#taints-and-tolerations-beta-feature)
