カテゴリ： GCP PHP

前提

ローカル開発用サーバまで構築済み。
（ただし、ルーティングの動作確認は実際にデプロイしないと確認できない）

ローカル環境 → OS：macOS 14.5 sonoma

ディレクトリ構成

下記のディレクトリ構成で行う。

root
├ app.yaml
├ dispatch.yaml
├ index.php
├ service1
│ ├ service1.yaml
│ └ index.php
└ service2
　 ├ service2.yaml
　 └ index.php

デプロイ

開発用サーバで動作確認できれば良いが、手順が見つからなかったので、実際にデプロイして確認する。

defaultを含む3つのサービスをデプロイする

下記コマンドを実行する。

% gcloud app deploy
% gcloud app deploy service1/service1.yaml service2/service.yaml

service1 と service2 をデプロイした時のログは下記の通り。

Services to deploy:

You can stream logs from the command line by running:
  $ gcloud app logs tail -s <service>

To view your application in the web browser run:
  $ gcloud app browse -s <service>

この時点で下記URLに対してアクセス可能。

ただし、インスタンスがサービスの数だけ立ち上がるので注意。
