ヘルムチャートとテンプレートの操作の基本-パート1

このチュートリアルでは、HelmがKubernetesアプリケーションの管理を簡素化するのにどのように役立つかについて簡単に説明し、Helmを使用して基本的なグラフを作成する方法を学びます。







アプリケーション管理はKubernetesの複雑な側面です。Helmは、バージョン管理をサポートする統合ソフトウェアパッケージング方法を提供することにより、はるかに簡単になります。Helmは、yumやaptと同じように、Kubernetesのパッケージ（HelmではChartsと呼ばれます）をインストールして管理します。







このチュートリアルでは、Helmに基本的なチャートを作成させます。このチュートリアルは、Helmとは何かについて少なくとも基本的な知識があることを前提としています。慣れていない場合は、記事を開始する前にこのチュートリアルを読むことをお勧めします：https：//www.alibabacloud.com/help/doc-detail/86511.htm







次に、値ファイルとテンプレートの部分がどのように連携するかを確認するために、段階的に調整します。







このような基本的な作業チャートを使用すると、最初から作業するよりも簡単に作業できます。







チャートはヘルムパッケージです。これには、Kubernetesクラスター内でアプリケーション、ツール、またはサービスを実行するために必要なすべてのリソース定義が含まれています。







これは、Homebrew式、Apt dpkg、またはYumRPMファイルに相当するKubernetesと考えてください。
