你可以在 [Docker 關於 shell 與 exec 形式的文件](https://docs.docker.com/reference/dockerfile/#shell-and-exec-form) 閱讀更多。

使用 `docker compose` 時這會特別明顯。技術細節請見這段 Docker Compose 常見問題：[為什麼我的服務要花 10 秒才重新建立或停止？](https://docs.docker.com/compose/faq/#why-do-my-services-take-10-seconds-to-recreate-or-stop)

#### 目錄結構 { #directory-structure }

你現在應該會有如下的目錄結構：

 * model to address problems that the others don't.
