google app engine
Standard environmentとFlexible environment
サービスが動く環境が2種類用意されている。
Standard
The PHP 7.2 runtime is capable of running any framework, library, or binary.
The PHP 5.5 runtime does not allow native code, filesystem access, or arbitrary network connections, and has proprietary APIs.
Optimized to scale nearly instantaneously to handle huge traffic spikes.
Flexible
Open source runtimes capable of running any framework, library, or binary.
Greater CPU and memory instance types.
Can access resources in the same Compute Engine network.
PHP 5.6, 7.0, 7.1, 7.2
これを読むと違いがわかる。
フレキシブル環境は、スタンダード環境を補完することを目的としています
展開
app.yamlに展開環境やURLパターン等を書き、以下のコマンドで展開できる
$ gcloud app deploy
本当に展開しますか?的なことを聞かれれるのが面倒なので-qオプションをつける
$ gcloud app deploy -q
エイリアス組んでおく。terminal-notifierを使って終わったら通知してくれるように。
.bashrc
alias gad='gcloud app deploy ; terminal-notifier -title "gcloud app deploy" -message done -sound a'
alias gadq='gcloud app deploy -q ; terminal-notifier -title "gcloud app deploy" -message done -sound a'
alias gab='gcloud app browse'
app.yamlメモ
ここを見ながらやっていくが書かれていない挙動がちょいちょいあるので注意
https://cloud.google.com/appengine/docs/standard/php/config/appref?hl=ja
最初構成チェック
app.yamlというファイルに書かれた情報を元に展開される。
展開するだけならapp.yamlファイルさえあれば良い? と思ったけど空のapp.yamlだと展開時にエラー
ちなみにapp.ymlはダメ。エラーがでる
ERROR: An app.yaml (or appengine-web.xml) file is required to deploy this directory as an App Engine application. Create an app.yaml file using the directions at https://cloud.google.com/appengine/docs/flexible/python/configuring-your-app-with-app-yaml (App Engine Flexible Environment) or https://cloud.google.com/appengine/docs/standard/python/config/appref (App Engine Standard Environment) under the tab for your language.
app.yaml
何もかかない
結果.yaml
ERROR: (gcloud.app.deploy) An error occurred while parsing file: [path/app.yaml]
適当なruntimeを書くとINVALID_ARGUMENTと怒られるがGoogle Cloud Storageにupはされる。
app.yaml
runtime: piyo
結果.yaml

ならばphpと書くと、、、エラー。phpと書くとデフォルトでphp54になるが、php54は使用できないよということかな
app.yaml

If you need to continue to deploy PHP 5.4 applications for compatibility reasons, you can request that your application be whitelisted for PHP 5.4 deployment by visiting http://goo.gl/qjKEuk.
翻訳.yaml
PHP 5.4アプリケーションは、古いバージョンを含むSDKのどのバージョンからもGoogle App Engineにデプロイされません。互換性の理由から引き続きPHP 5.4アプリケーションをデプロイする必要がある場合は、http：//goo.gl/qjKEukにアクセスして、アプリケーションをPHP 5.4デプロイ用にホワイトリストに登録するように要求できます。
php54でもデプロイできるのかな -> ダメでした。
app.yaml

php55にしてみる。handler書けって言われた。
app.yaml

php55 + handler書くと展開成功。しかしブラウザでアクセスすると404エラー
app.yaml
runtime: php55
handlers:
- url: /(.+\.php)$
script: \1

You can stream logs from the command line by running:
$ gcloud app logs tail -s default
To view your application in the web browser run:
$ gcloud app browse
stackdriverのログみると↓のエラーが出てた。index.phpが必要なのか
ERROR: serve handler failed: inferring default front controller: front controller not found at any of these paths: [public/index.php index.php]
index.phpを用意し展開すると正常にアクセスできた。
index.php
<?php
echo "PHP " . phpversion();
一旦app.yamlをruntimeだけにし、index.phpを削除しruntime php72を試す。
-> 展開は成功した。
-> .gcloudignoreファイルが自動的に作られた。
-> handlerは書かなくても展開される
app.yaml
runtime: php72
結果.yaml
Beginning deployment of service [default]...
Created .gcloudignore file. See `gcloud topic gcloudignore` for details.

自動生成された.gcloudignore
# This file specifies files that are *not* uploaded to Google Cloud Platform
# using gcloud. It follows the same syntax as .gitignore, with the addition of
# "#!include" directives (which insert the entries of the given .gitignore-style
# file at that point).
#
# For more information, run:
# $ gcloud topic gcloudignore
#
.gcloudignore
# If you would like to upload your .git directory, .gitignore file or files
# from your .gitignore file, remove the corresponding line

index.phpを作って展開するとphp72になっていることが確認できた。
