遅まきのHerokuデビューを無料枠でしたよ。phpinfo()を作ってデプロイ編

チュートリアルは分かったので、今度はスクラッチで作成して公開するまでの手順を確認しておこう。

まずは適当なディレクトリを作る。そしてそのディレクトリの下に移動。

$ mkdir phpinfo
$ cd phpinfo/

index.phpとcomposer.jsonを作る。composer.jsonは空に近い状態でいい。

phpinfo();

{
    "require": {
    }
}

このままcomposer updateを実行する。

$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files

そうするとvenderディレクトリが作成されているので、ここでgit initする。

$ git init
Initialized empty Git repository in /Users/hogahoga/Documents/HerokuProject/phpinfo/.git/

全てのファイルをaddし、ローカルリポジトリにコミットする。

$ git add *
$ git commit -m "Initial Commit"
[master (root-commit) 3852af9] Initial Commit

遅まきのHerokuデビューを無料枠でしたよ。準備編〜その2

さて昨日の遅まきのHerokuデビューを無料枠でしたよ。準備編〜その1からの続き。

さてHeroku上にアプリケーションを作成する。

Deploy the app

In this step you will deploy the app to Heroku.
Create an app on Heroku, which prepares Heroku to receive your source code:

$ heroku create
Creating sharp-rain-871... done, stack is cedar-14
http://sharp-rain-871.herokuapp.com/ | https://git.heroku.com/sharp-rain-871.git
Git remote heroku added

When you create an app, a git remote (called heroku) is also created and associated with your local git repository.
Heroku generates a random name (in this case sharp-rain-871) for your app, or you can pass a parameter to specify your own app name.

この後、GitHubから取ってきたソースをHerokuにデプロイしていくようだ。ローカルのgitリポジトリからHerokuのリモートリポジトリへアップする。なんかいっぱい入った。

$ git push heroku master

Delta compression using up to 4 threads.

ここでwebインスタンスを１つ動かす。

The application is now deployed. Ensure that at least one instance of the app is running:

$ heroku ps:scale web=1

これでサイトの準備ができたので、下記のコマンドでデプロイされたアプリがブラウザで確認できる。

Now visit the app at the URL generated by its app name. As a handy shortcut, you can open the website as follows:

$ heroku open

できた！

起動させた時のログはheroku logsを使う。

遅まきのHerokuデビューを無料枠でしたよ。準備編〜その1

結構前（３年ぐらい？）からHerokuは流行ってるのは知ってたんだけど、仕事内容でいまいち関わることが無かったのでスルーしてた。
でも最近になって触るような機会とPaaSの流行りがやっと来た感があるので試してみた。もうこんな記事はちまたに出回りすぎるぐらい出ているんだけど。

ちょっと前（2015年5月）にプライス設定が見直しになってたみたいで今は無料利用での制限が色々と厳しくなってる模様。それでも開発の時やテスト的には全然使えると思う。

• SLEEPS AFTER 30 MINS OF INACTIVITY
• 30分稼働がないとスリープしてしまう
• MUST SLEEP 6 HOURS IN A 24 HOUR PERIOD
• 24時間中、6時間はスリープする必要あり
• CUSTOM DOMAINS
• 独自ドメインが使える
• 512 MB RAM │ 1 web/1 worker
• dynoと呼ばれるプロセス？コンテナ？みたいな考えのWebタイプとWorkerタイプが１つずつ使える
• Dynos and the Dyno Managerに書いてあった

さっそくサインアップを済ませてログイン。ダッシュボードは本日時点でこんな感じ。

"PHP Get Started"を選ぶ。

StartまでのTutorialが出てきた。

Introduction

This tutorial will have you deploying a PHP app in minutes.
Hang on for a few more minutes to learn how it all works, so you can make the most out of Heroku.
The tutorial assumes that you have:
・a free Heroku account.
・PHP installed locally.
・Composer installed.

はじめにPCにHerokuを使うために"Heroku Toolbelt"なるものをインストールしなきゃならんらしい。なのでこれをダウンロードしてインストールする。Windows版しかなかったら暴れているところだが、無事Mac版も用意されていた。

Set up

In this step you will install the Heroku Toolbelt. This provides you access to the Heroku Command Line Interface (CLI), which can be used for managing and scaling your applications and add-ons. A key part of the toolbelt is the heroku local command, which can help in running your applications locally.

Once installed, you can use the heroku command from your command shell.
Log in using the email address and password you used when creating your Heroku account:

pkgをダウンロードし、インストール完了したらおもむろにTerminalを開いてheroku loginと打ってコマンド実行。

$ heroku login
heroku-cli: Installing Toolbelt v4... done
For more information on Toolbelt v4: https://github.com/heroku/heroku-cli
heroku-cli: Adding dependencies... done
heroku-cli: Installing core plugins... done
Enter your Heroku credentials.

$

成功したみたいだけれど、恐ろしく成功感がない。次はGitHubからサンプルソースを引っ張ってこいみたいなことが書いてあるので、適当な場所にHeroku用のフォルダを作ってそこで作業することにした。

Prepare the app

In this step, you will prepare a simple application that can be deployed.
Execute the following commands to clone the sample application:

$ git clone https://github.com/heroku/php-getting-started.git
$ cd php-getting-started

You now have a functioning git repository that contains a simple application as well as a composer.json file. Make sure you've installed Composer. Heroku uses Composer for dependency management in PHP projects, and the composer.json file indicates to Heroku that your application is written in PHP.

パッケージ管理にComposerを使っているみたい。だからComposer入れとけとか書いている。正直準備でだいぶだるい。

先にComposerをインストールする。

$ curl -sS https://getcomposer.org/installer | php
Some settings on your machine may cause stability issues with Composer.
If you encounter issues, try to change the following:

The OpenSSL library (0.9.8zc) used by PHP does not support TLSv1.2 or TLSv1.1.
If possible you should upgrade OpenSSL to version 1.0.1 or above.

Downloading...

Composer successfully installed to: /Users/fumio/Documents/HerokuProject/php-getting-started/composer.phar
Use it: php composer.phar

/usr/local/binあたりに移動させる。

$mv composer.phar /usr/local/bin/composer

実行してこうなったら入ってるんじゃないかと思う。

$ composer

さてGitHubから引っ張ってくる。

$ git  clone https://github.com/heroku/php-getting-started.git

index.phpの中身だけ見てみた。

require('../vendor/autoload.php');

$app = new Silex\Application();
$app['debug'] = true;

// Register the monolog logging service
$app->register(new Silex\Provider\MonologServiceProvider(), array(
  'monolog.logfile' => 'php://stderr',
));

// Register view rendering
$app->register(new Silex\Provider\TwigServiceProvider(), array(
    'twig.path' => __DIR__.'/views',
));

// Our web handlers

$app->get('/', function() use($app) {
  $app['monolog']->addDebug('logging output.');
  return $app['twig']->render('index.twig');
});

$app->run();

だめだ。今日はここまで！
