Spring BootをHerokuにデプロイするのが劇的に簡単になっている件

Posted at

はじめに

以前herokuでspring-bootをgradleを使ってデプロイするときのコツの記事で紹介したspring-bootをherokuにデプロイするやり方を書いたが、最近はコツがなくてもデプロイできるようになっていたので改めて試してみた。

手順

手順はHeroku公式のDeploying Spring Boot Applications to Herokuに書いてあるとおり実施。Spring BootのプロジェクトをIntelliJから作るところだけ俺流です。

  • herokuにアカウントを作る(ない人だけ)
  • Heroku CLIをインストール(インストールしていない人だけ)
  • Herokuにログイン
  • IntelliJのSpringInitializrからSpringBootのプロジェクトを作成
  • gitにコミット
  • herokuにアプリケーション作成
  • herokuにpush

環境

  • Mac 10.10
  • IntelliJ IDEA 2016.2

詳細な手順

herokuのアカウント作成(アプリケーションではなくHerokuのアカウントのこと)とHeroku CLIのインストールは割愛します。（公式ページを参考にしてください）

Heroku CLIをつかってHerokuにログインする

❯❯❯ heroku login
Enter your Heroku credentials.
Email: gosshys@gmail.com
Password (typing will be hidden): 
Logged in as gosshys@gmail.com

IntelliJからSpring Bootのプロジェクトを作成

  • メニュー「File」->「New」->「Project」を選択
    image

  • 左ペインの　「Spring Initializr」を選択して、「Next」ボタンで次へ
    image

  • 「Type」を『Gradle Project』に変更して、「Next」ボタンで次へ(Mavenでもいい、Mavenのほうがいいかも)
    image

  • 「Web」のWebと「Ops」のActuatorくらいを選択して、「Next」ボタンで次へ(Actuatorは任意、あると便利)
    image

  • デフォルトの設定でいいので、「Finish」ボタンで終了
    image

  • Gradleの設定を聞かれるのでお好みの設定で「OK」ボタンで進む(ここでGradle入れてない人は詰まる)
    image

  • できた
    image

gitにコミット

これも公式ページのPreparing a Spring Boot app for Herokuのとおりにgitにコミットする
