【 PHP 】PHP8に入門してみた 14日目 環境構築を進める ( VS Codeなど )
PHP8技術者認定初級試験 が始まるようなので 試験に向けて (できるだけ)勉強しようと思います！ 
使用する書籍は独習PHP 第4版（山田 祥寛）｜翔泳社の本 (shoeisha.co.jp) となります。
環境構築を進める
VS Codeなど
Dockerイメージを作成する
nginx
つづいてnginxのDockerイメージをビルドします。
nginxはあっという間にビルドが終わりました。
問題なさそうですね。

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them
PS D:\dockers\files\php8_study\.devcontainer>php
次はphpとなります。FPM(FastCGI Process Manager)と呼んでいる方ですね。
学習ではworkspaceとphpのどちらを使うのでしょうか？

PS D:\dockers\files\php8_study\.devcontainer>mariadb
最後にmariadbですね。
サービス名がmysqlのままなのですが・・・まぁ良しとします😉
mariadbは単純にDockerイメージがたくさん保存されている場所(Docker Hub)から持ってくるだけなのでビルドは必要ありません。
実は「ビルド」の時もDocker HubからDockerイメージを持ってきています。このイメージをさらにカスタマイズするのが「ビルド」なのです。
「持ってくる」は「pull」というコマンドを使います。
PS D:\dockers\files\php8_study\.devcontainer> docker-compose pull mysql
Pulling mysql ... done
メモ
動作するかわかりませんがdocker-compose.ymlの定義およびビルドはオールオッケー！
