何が起きたか
laravelのプロジェクトを開発する際に、laravelのapp用のコンテナとcomposer用のコンテナを用意してdocker-composeで環境を起動するのが僕の主流になっているのですが、
つい先日久しぶりに環境を立ち上げたら

ComposerイメージのPHPバージョンアップが原因
調べていくと下記qiita記事に出くわしました。
PHP 8.1 がリリース！だけど思わぬ落とし穴も - Qiita | Qiita
PHP 8.1 がリリース！2021年11月25日に PHP 8.1 がリリースされました https://www.php.net/releases/8.1/en.phpenum の追加や re…

ComposerイメージはPHPを内包してくれているので、単体で動作できるようになっているスグレモノなのですが、
最新のComposerイメージはPHP8.1を利用するようになっていました。
一方で今回立ち上げようとしていたlaravelのバージョンはlaravel6で、PHP8.1に対応していません。
バージョンのミスマッチに依るエラーでした。
利用するComposerイメージを下げることで解決
上記記事の解決策に倣い、Composerイメージをcomposer:2.1.11に下げました。
