Q&A
EC2のコンテナ上で展開しているPHPの環境があり、composerで構成しています。
composerを実行したところ、メモリ不足で実行できませんでした。
Loading composer repositories with package information Updating dependencies (including require-dev) mmap() failed: [12] Cannot allocate memory mmap() failed: [12] Cannot allocate memory Fatal error: Out of memory (allocated 386723840) (tried to allocate 9210786 bytes) in phar:///usr/bin/composer.phar/src/Composer/Util/RemoteFilesystem.php on line 459
メモリの上限をあげる方法を色々試してみたのですが、解決できず何か他に変更する方法はないでしょうか？
サーバーの性能について
EC2のt2.microインスタンスを使っていますので、メモリは1GBです。
実際に使用できるメモリ容量は約1GB弱なので、容量が不足している可能性はないと思われます。
sh
1$ docker stats (dockerコンテナ)
| MEM USAGE | LIMIT |
|---|---|
| 8.277MiB | 983.7MiB |
試した事
php.iniファイルの上限をあげる
phpの設定で上限を変えるために、docker-compose up時に追加するiniファイルにmemory_limit = 512Mにして立ち上げました。
ini
1[php] 2memory_limit = 512M
しかし、tried to allocate上限は変わりません。
実際にコンテナにexecで入り、phpinfo()から直接確認しましたが、設定自体は変わっている事を確認しました。
sh
1$ php -r 'phpinfo();' | grep memory_limit 2memory_limit => 512M => 512M
コマンドラインで実行した時だけ、メモリの制限上限を
phpとcomposerそれぞれのメモリリミットを変更して見ましたが、メモリが変わりません。
phpのリミットを変更
上限を解除するために、memory_limitオプションを追加した状態でビルドしてみました。
sh
1$ php -d memory_limit=-1 /usr/bin/composer install
composerのリミット変更
上限を解除するために、COMPOSER_MEMORY_LIMITオプションを追加した状態でビルドしてみました。
sh
1$ COMPOSER_MEMORY_LIMIT=-1 composer install
composer時のログ
リミット変更時に、変更があるかもしれないと思いcomposer install -vvvで見てみましたが、知識不足で原因を見つけることができませんでした。

実際に使用できるメモリ容量は約1GB弱なので、容量が不足している可能性はないと思われます。
これの根拠は、freeコマンドの結果でしょうか。
docker以外にも立ち上がっているプロセスがあれば、より少ない可能性があります。
（composerが400MB使用しているので）
また、swapは作成されていますか？
