CircleCI 2.1 設定サンプル(Rails + Rspec + Rubocop + Jest + ESLint + Yarn + Postgres)

Last updated at Posted at 2020-02-09

環境

  • Circle CI 2.1
  • Rails 5 + PostgresSQL 9.6 + Yarn
    • 主にCircle CIの設定のため、上記環境には大きく依存していません。

やっていること

  • テストの実行(rspecjest
    • simplecov を使って、rspec 実行結果の code coverage を CircleCI 上のARTIFACTSに残しています。
  • Linterの実行(rubocopeslint
  • セキュリティチェック(brakeman
  • デプロイ
    • developmasterブランチへマージされた時に、capistranoを使って各staging、production環境にデプロイ。
    • 結果をslackに通知。
    • capistranoの設定ファイル(config/deploy/staging.rb等)で、set :branch, ENV['BRANCH'] || 'develop'等として、ブランチの設定がされている必要があります。
  • 上記に付随する処理(ソースコード、ライブラリのインストール及びキャッシング)

出来ていないこと

  • fingerprintを環境変数で設定すべき

ポイント

  • こちらをどうぞ
  • ソースコードもキャッシュしていますが、常にキャッシュした方が速いとは限りません。

    とはいえ、ソースコードのキャッシュの有無によってビルド速度が向上するかどうかは検証した方が良い場合もあります。例えば restore_cache するより git clone を実行する方が高速な場合も多々あります。
    https://circleci.com/docs/ja/2.0/caching/#%E3%82%BD%E3%83%BC%E3%82%B9%E3%82%B3%E3%83%BC%E3%83%89%E3%81%AE%E3%82%AD%E3%83%A3%E3%83%83%E3%82%B7%E3%83%A5

  • ベースのDockerイメージ(circleci/ruby:2.6.3-node)で、BUNDLE_PATHが設定されているので、BUNDLE_PATH: vendor/bundleとして上書きしています。

  • gem install bundler時に、Gemfile.lockで使われているbundlerのバージョンを指定してインストール方法として、ここを参考にして、以下の方法を試しましたが、何故か最新のものがインストールされてしまったので、gem install bundler:$BUNDLER_VERSIONとしています。

  echo 'export BUNDLER_VERSION=$(cat Gemfile.lock | tail -1 | tr -d " ")' >> $BASH_ENV
  source $BASH_ENV
  gem install bundler
