+description: A Helm chart for Kubernetes
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 3.0.0-beta1
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.

+1. `jetdisc` アプリケーションがKubernetesクラスターにデプロイされました。
+
+2. アプリケーションは、指定された設定に基づいて起動しています。設定の詳細は `values.yaml` ファイルを参照してください。
+
+3. アプリケーションは、PythonとNode.js環境で構築されており、Dockerfileに定義された手順に従ってコンテナイメージがビルドされています。
+
+4. このデプロイメントには、Kubernetes APIへのアクセスが必要な場合に使用するための `ServiceAccount` が含まれているかもしれません。APIとの直接のやり取りが必要ない場合は、このアカウントは使用されません。
+
+5. アプリケーションのスケーリングにはHPA（Horizontal Pod Autoscaler）が設定されており、CPU使用率やメモリ使用率に基づいて自動的にポッドの数が調整されます。HPAの設定は `values.yaml` で確認および変更が可能です。
+
+6. デプロイメントの状況を確認するには、以下のコマンドを実行してください:
+
+```
+kubectl get deployment {{ include "jetdisc.fullname" . }}
+```
+
+7. リリースの削除には、以下のコマンドを実行してください:
+
+```
+helm delete {{ include "jetdisc.fullname" . }}
+```
+
+8. アプリケーションのログを確認するには、以下のコマンドを実行してください:
+
+```
+kubectl logs -f deployment/{{ include "jetdisc.fullname" . }}
+```
