<h1>継続的インテグレーション</h1>
<p><!-- Continuous integration (CI) automates building, testing and deploying
applications. -->
継続的インテグレーション（CI）はビルド、テスト、デプロイを自動化するための方法です。</p>
<!-- ## Why is continuous integration important? -->

<h2>継続的インテグレーションはなぜ重要？</h2>
<p><!-- When CI is set up well it can dramatically reduce deployment times by
eliminating manual steps and ensure code does not have bugs that are being
checked by automated tests. Source code changes as a project evolves.
CI combined with unit and integration tests check that code modifications
do not break existing tests ensure the software works as intended. -->
CIを正しくセットアップすると、自動テストにより手動で動作確認するよりもデプロイにかかる時間を大幅に縮小できます。ソースコードはプロジェクトが進めば変わっていきます。CIをユニットテスト、インテグレーションテストと連携することで、コードの編集によりアプリケーションが壊れる心配は無くなるでしょう。</p>
<!-- ## Continuous integration example -->

<h2>継続的インテグレーションの例</h2>
<p><!-- The following picture represents a high level perspective on how continuous
integration and deployment can work. -->
以下の図は、継続的インテグレーションとデプロイの役割を表したものです。</p>
<p><img src="theme/img/continuous-integration.png" width="100%" class="technical-diagram" alt="継続的インテグレーションの一例" /></p>
<!-- In the above diagram, when new code is commited to a source repository
there is a hook that notifies the continuous integration server that new
code needs to be built (the continuous integration server could also
poll the source code repository if a notification is not possible). -->

<p>上の図ではレポジトリに新しいコードがコミットされたら、新しいコードをビルドするように、CIサーバに通知が送られます。（通知を送ることができないCIサーバの場合、レポジトリサーバを定期的にチェックする必要があります。）</p>
<!-- The continuous integration server pulls the code to build and test it. If
all tests pass, the continuous integration server begins the deployment
process. The new code is pulled down to the server where the deployment is
taking place. Finally the deployment process is completed via restarting
services and related deployment activities. -->

<p>CIサーバはコードを取り込みビルドとテストを行います。全てのテストが成功したらデプロイプロセスを始めます。デプロイが始まるとサーバへ新しいコードが取り込まれ、サービスの再起動や他のデプロイプロセスを行った後、デプロイプロセスが完了します。</p>
<!-- There are many other ways a continuous integration server and its
deployments can be structured. The above was just one example of a
relatively simple set up. -->

<p>CIサーバとデプロイのプロセスの構成方法は様々な形式があります。上で説明したセットアップはシンプルな構成例の一つでしかありません。</p>
