dockerコンテナで作成したPHP実行環境のプログラムをvscodeのxdebugでデバッグできる環境を作成する

こんにちは、プロクラスの國府です。

今回は、タイトルの通り「dockerコンテナで作成したPHP実行環境のプログラムをvscodeのxdebugでデバッグできる環境を作成する」の手順を公開していきます。

タイトル分かりずらいから、何ができて便利になるの？

タイトルの文言ではわかりにくいの、図にしてみました。

図を使って説明します。

• ピンクの矢印の部分

dockerの設定を使って,OSとPHPコンテナ間,OSとWebサーバコンテナ間でファイル共有します。そうすることでVS Codeで編集したファイルがPHPコンテナとWebサーバコンテナに反映されます。

• オレンジの矢印の部分

VS Codeのプラグイン「Dev Containters」を使うことで、1つのコンテナの実行環境を丸々VS Codeから操作することができます。今回は、PHPコンテナ(X Debug含む）に接続し、VS Codeのプラグイン「PHP Debug」でX Debugを操作します。

つまり、

ホストOSの環境（レジストリ、環境変数など）を汚さず、隔離された環境で、FTPやGitを使ったデプロイ作業不要で即座に実行動作が確認できる。X Debugでコードがトレース（プログラムのどの命令をたどっていたかの形跡）やプログラムを任意の時点で停止し、その時点での変数の内容を確認できる、そういった開発環境を構築しようということになります。

Dockerコンテナの作成

docker-composeを使用して、コンテナを作成していきます。

今回作成するdocker-composeのディレクト・ファイル構成は、下記の図の通りとなります。

ファイルの内容や役割や設定項目について説明します。

設定項目に関しては、ファイル内容のコメント部分で説明しています。

        "../docker-compose.yml"
    ],

                "mosapride.zenkaku"

        }
