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：

## 再起動 { #restarts }

起動時にアプリケーションが実行されることを確認するのと同様に、失敗後にアプリケーションが**再起動**されることも確認したいと思われます。

### 我々は間違いを犯す { #we-make-mistakes }

私たち人間は常に**間違い**を犯します。ソフトウェアには、ほとんど常に**バグ**があらゆる箇所に隠されています。🐛

そして私たち開発者は、それらのバグを見つけたり新しい機能を実装したりしながらコードを改善し続けます（新しいバグも追加してしまうかもしれません😅）。

### 小さなエラーは自動的に処理される { #small-errors-automatically-handled }
