### 여러 프로세스 - 예시 { #multiple-processes-an-example }

이 예시에서는 **Manager Process**가 두 개의 **Worker Processes**를 시작하고 제어합니다.

이 Manager Process는 아마 IP의 **포트**에서 리스닝하는 역할을 합니다. 그리고 모든 통신을 워커 프로세스로 전달합니다.

워커 프로세스들이 실제로 애플리케이션을 실행하며, **요청**을 받아 **응답**을 반환하는 주요 연산을 수행하고, RAM에 변수로 로드한 모든 내용을 담습니다.

A container is running as long as the **main process** (command or program) is running.

A container normally has a **single process**, but it's also possible to start subprocesses from the main process, and that way you will have **multiple processes** in the same container.

But it's not possible to have a running container without **at least one running process**. If the main process stops, the container stops.
