+# Rails 8.1 + SQLite 应用
+
+这是一个基于Rails 8.1和SQLite的示例应用，部署在JPD K3s集群上。
+
+## 功能特性
+
+- Rails 8.1 最新版本
+- SQLite 数据库（持久化存储）
+- GitOps自动部署（Gitea + ArgoCD）
+- 域名访问：http://r1.jpd.net3w.com
+- 代码热更新（本地修改，远程自动部署）
+
+## 目录结构
+
+```

+
+## 部署流程
+
+1. 本地开发Rails应用
+2. 构建Docker镜像
+3. 推送到Gitea仓库
+4. ArgoCD自动检测并部署
+5. 通过域名访问应用
+
+## 访问地址
+
+- HTTP: http://r1.jpd.net3w.com
+- HTTPS: https://r1.jpd.net3w.com
+
+## 开发流程
+
+1. 本地修改代码
+2. Git commit & push
+3. ArgoCD自动同步
+4. 应用自动更新
