予め作成されたコンテナ・イメージを使用することで、異なるツールを**組み合わせて**使用することが非常に簡単になります。例えば、新しいデータベースを試す場合に特に便利です。ほとんどの場合、**公式イメージ**を使い、環境変数で設定するだけで良いです。

そうすれば多くの場合、コンテナとDockerについて学び、その知識をさまざまなツールやコンポーネントによって再利用することができます。

つまり、データベース、Pythonアプリケーション、Reactフロントエンド・アプリケーションを備えたウェブ・サーバーなど、さまざまなものを**複数のコンテナ**で実行し、それらを内部ネットワーク経由で接続します。

すべてのコンテナ管理システム（DockerやKubernetesなど）には、こうしたネットワーキング機能が統合されています。
