#### Dockerキャッシュ

この`Dockerfile`には重要なトリックがあり、まず**依存関係だけのファイル**をコピーします。その理由を説明します。

```Dockerfile
COPY ./requirements.txt /code/requirements.txt
```

Dockerや他のツールは、これらのコンテナイメージを**段階的に**ビルドし、**1つのレイヤーを他のレイヤーの上に**追加します。`Dockerfile`の先頭から開始し、`Dockerfile`の各命令によって作成されたファイルを追加していきます。

Dockerや同様のツールは、イメージをビルドする際に**内部キャッシュ**も使用します。前回コンテナイメージを構築したときからファイルが変更されていない場合、ファイルを再度コピーしてゼロから新しいレイヤーを作成する代わりに、**前回作成した同じレイヤーを再利用**します。
