Dockerfile Misconfiguration: Privileged Container

Docker

Abstract

Dockerfile は、root ユーザーで実行するコンテナーを設定します。

Explanation

root に設定された USER 命令を持つ Dockerfile には、コンテナー内で変更を加えるための、過度に許容的な特権があります。これは、最小限の特権でイメージを実行するという原則に違反します。通常の場合、パッケージをインストールしてフォルダを作成するには、root 権限が必要になる可能性があります。インストールが完了したら、制限された権限を持つユーザーを追加することをお勧めします。
