基于 WEB-UI-Development-Guide 标准的整体升级,并更名 LokiDeploy → opsx-loki。 前端(Gin+React+shadcn/ui): - 按 02/07 章重构:页面域化拆分(无超 400 行文件)、PageContainer/ListQuery、 反馈分级(成功静默/失败 toast/危险确认)、401 单飞刷新+队列重放 - 暗色模式(next-themes)+ 语义 Token(--primary 品牌色/success/warning/info) - 部署向导(状态推导四步:环境→存储→Loki→采集,内嵌表单闭环) - 日志查询页:LogQL 标签构建器/拖拽直方图/日志上下文/Live Tail/查询历史 - 按用户+标签策略的查询授权(服务端强制合并策略) 后端(Go+Gin+JSON DB): - 简单用户管理(仅 admin,无 RBAC)+ TokenVersion 会话吊销 + 登录 IP 限流 - LDAP 接入:配置(AES 加密存储/hasPassword 脱敏)/测试连接/批量导入/登录 - 存储配置测试连接(SigV4 零依赖)+ 桶不存在自动创建 - Loki 三模式部署修复:SSH 密钥认证、3.x 配置模板、ruler 对象存储嵌套块、 凭证解密、孤儿 deploying 状态恢复、Grafana 部署(可选默认关)+面板导入 - DaemonSet 采集纯 YAML(去 helm 依赖)+ DNS 自愈回退 ClusterIP + 集群名标签 - 日志查询代理:cluster-svc 经 kube-apiserver proxy/url 直连 + cursor 翻页 - 统一 log 命名空间;部署就绪探活;Grafana 访问地址自动记录 修复:run.sh 增量编译检测、Sanitized 脱敏补全、LokiDeployment Update 白名单、 健康检查 CreatedAt 零值等 10+ 存量 bug。 数据兼容:DB 沿用旧 lokideploy.json(新名优先);localStorage 一次性迁移; HKDF 加密前缀保留(已加密凭证不受影响)。
