若你的應用「很簡單」，這可能「不是問題」，你可能不需要指定嚴格的記憶體限制。但如果你「使用大量記憶體」（例如使用機器學習模型），你應該檢查實際消耗的記憶體，並調整「每台機器上執行的容器數量」（也許還要為叢集加機器）。

若你採用「每個容器多個行程」，你就得確保啟動的行程數量不會「超過可用記憶體」。

## 啟動前的前置步驟與容器 { #previous-steps-before-starting-and-containers }

如果你使用容器（例如 Docker、Kubernetes），那有兩種主要做法可用。

### 多個容器 { #multiple-containers }

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。

**컨테이너당 여러 프로세스**를 실행한다면, 시작되는 프로세스 수가 사용 가능한 것보다 **더 많은 메모리를 소비하지** 않는지 확인해야 합니다.

## 시작 전 단계와 컨테이너 { #previous-steps-before-starting-and-containers }

컨테이너(예: Docker, Kubernetes)를 사용한다면, 사용할 수 있는 주요 접근 방식은 두 가지입니다.

### 여러 컨테이너 { #multiple-containers }
