+# n8n Helm Chart - CLAUDE.md
+
+## リポジトリ概要
+
+n8n ワークフロー自動化ツールを Kubernetes 上にデプロイするHelmチャートです。
+Raspberry Pi などのベアメタル上で動作する Kubernetes クラスタを想定した構成になっています。
+`n8nio/n8n` 公式マルチアーキテクチャイメージ（linux/arm64 対応）を使用します。
+
+## ARM 対応について
+
+`n8nio/n8n` は linux/arm64 に対応したマルチアーキテクチャイメージです。
+Raspberry Pi 4 以降（arm64）で動作します。
+
+## Git 情報
+
+- **ユーザー名**: Claude
+- **メールアドレス**: claude@cafepieters.com
+- **リポジトリ**: ssh://git@192.168.9.65/helmchart/n8n.git
+
+## チャート構成
+
+| リソース | 説明 |
+|---|---|
+| Deployment | n8n 本体（シングルコンテナ） |
+| Service | LoadBalancer / ClusterIP（ポート 5678） |
+| PVC | n8n データ（ワークフロー・認証情報・SQLite DB）永続化 |
+| Secret | 暗号化キー・Basic認証パスワード・DBパスワード |
+| Ingress | オプション（nginx ingress controller 対応） |
+| HPA | オプション（※SQLiteモード時はスケールアウト非推奨） |
+| PDB | Pod Disruption Budget |
+| NetworkPolicy | オプション |
+
+## データ永続化
+
+n8n のデータは `/home/node/.n8n` に保存されます。
+`persistence.enabled: true`（デフォルト）で PVC に永続化されます。
+**persistence.enabled: false の場合、Pod 再起動でデータが失われます。**
+
+## データベース
+
+- デフォルト: SQLite（`/home/node/.n8n/database.sqlite`）
+- 本番推奨: PostgreSQL（`n8n.database.type: postgresdb`）
+
+## リリースフローのルール
+
+### バージョン番号の方針
+- Helmチャートのバージョン番号（`Chart.yaml` の `version` / `appVersion`）は、**n8n のバージョン番号と同一**とする。
+
+### 自動リリース条件
+- **n8n バージョン更新時**: `values.yaml` と `Chart.yaml` を更新し、Gitタグ・Giteaリリース・Gitea Package Registry への発行まで行う。
+
+### 手動リリース（臨時）
+- 改修作業などで手動リリースが必要な場合は、バージョン末尾にアルファベットを付与する。
+  - 例: `2.19.2` → `2.19.2-a`, `2.19.2-b`
+
+## ワークフロー構成
+
+### `.gitea/workflows/image-update-and-release.yaml`
+毎週月曜日 3:00 AM（JST 12:00 PM）に自動実行され、以下を行う:
+1. Docker Hub から n8n の最新バージョンを取得
+2. 更新がある場合は `values.yaml` と `Chart.yaml` を更新
+3. Gitタグ・Giteaリリース・Gitea Package Registry への発行を実施
+
+### `.gitea/workflows/helm-release.yaml`
+`main` ブランチへのプッシュ時に自動実行。Gitea Package Registry にチャートを発行する。
+
+## 必要な Gitea Secrets
+
+| シークレット名 | 用途 |
+|---|---|
+| `GITEA_TOKEN` | Gitea API（リリース作成・タグ操作） |
+| `REGISTRY_USER` | Gitea Package Registry ユーザー名 |
+| `REGISTRY_TOKEN` | Gitea Package Registry トークン |
