如果你有「多個容器」，且每個容器大概都只執行「單一行程」（例如在一個 Kubernetes 叢集中），那你可能會想要一個「獨立的容器」來完成「前置步驟」的工作，並只在單一容器、單一行程中執行，接著才啟動多個複本的工作容器。

/// info | 資訊

如果你使用 Kubernetes，這大概會是一個 [Init Container](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/)。

///

如果你的情境中，讓那些前置步驟「平行重複執行多次」沒有問題（例如不是在跑資料庫遷移，而只是檢查資料庫是否就緒），那也可以把這些步驟放在每個容器中、在啟動主要行程前執行。

### 單一容器 { #single-container }

    - 一個 Uvicorn「管理行程」會在「IP」與「連接埠」上監聽，並啟動「多個 Uvicorn 工作行程」。
- Kubernetes 與其他分散式「容器系統」
    - 由「Kubernetes」層在「IP」與「連接埠」上監聽。複本的方式是有「多個容器」，每個容器內執行「一個 Uvicorn 行程」。
- 由「雲端服務」替你處理
    - 雲端服務很可能「替你處理複本」。它可能讓你定義「要執行的行程」或「容器映像」，無論如何，多半會是「單一 Uvicorn 行程」，而由雲端服務負責進行複製。

/// tip

先別擔心這裡提到的「容器」、Docker 或 Kubernetes 如果現在還不太懂。

我會在未來的章節進一步說明容器映像、Docker、Kubernetes 等等：[容器中的 FastAPI - Docker](docker.md)。

and work together in some way.">cluster</dfn> of machines with **Kubernetes**, Docker Swarm Mode, Nomad, or another similar complex system to manage distributed containers on multiple machines, then you will probably want to **handle replication** at the **cluster level** instead of using a **process manager** (like Uvicorn with workers) in each container.

One of those distributed container management systems like Kubernetes normally has some integrated way of handling **replication of containers**...
