+# 项目部署指南
+
+本项目依赖 `MongoDB`（事件持久化存储）与 `RabbitMQ`（mTLS 消息队列），并通过 `OpenTelemetry + Jaeger` 完成链路追踪。
+
+## 前提条件
+
+1. 已安装 `Docker` 与 `kubectl`
+2. `Minikube` 集群已启动并可访问
+3. 确保以下端口在宿主机上未被占用：`27017`（MongoDB）、`5671`（RabbitMQ AMQP）
+
+---
+
+### 1\. 部署 MongoDB 数据库
+
+EventRT 支持两种 MongoDB 部署方式，根据场景二选一：**Docker**（本地开发 / Ubuntu 宿主机直跑）或 **K8s**（Minikube 环境）。
+
+#### 1.1 Docker 部署（本地开发）
+
+使用官方 `mongo:7.0` 镜像，在 Ubuntu 宿主机（`192.168.1.101`）上以 Docker 容器运行。
+
+##### 1.1.1 部署命令
+
+```bash
+docker run --name mongodb \
+  -e MONGO_INITDB_ROOT_USERNAME=coslight \
+  -e MONGO_INITDB_ROOT_PASSWORD=coslight@tj \
+  -p 27017:27017 \
+  -d mongo:7.0
+```
+
+##### 1.1.2 连接信息
+
+| 参数 | 值 | 说明 |
+| :--- | :--- | :--- |
+| **容器名称** | `mongodb` | 容器名 |
+| **镜像版本** | `mongo:7.0` | MongoDB 7.0 |
+| **主机端口** | `27017` | 外部应用连接端口 |
+| **用户名** | `coslight` | Root 管理员 |
+| **密码** | `coslight@tj` | 启动时通过 `MONGO_INITDB_ROOT_PASSWORD` 设置 |
+| **鉴权数据库** | `admin` | `auth_db` |
+| **业务数据库** | `eventdb` | EventRT 事件存储库 |
+
+##### 1.1.3 状态检查
+
+```bash
+# 检查容器启动状态
+docker ps -a | grep mongodb
+# 检查启动日志
+docker logs mongodb
+```
+
+> **注意：** 密码当前以明文形式写在 `docker run` 命令中，生产环境应通过 Docker Secret 或环境变量文件（`--env-file`）传入，避免在 Shell 历史记录中留存明文密码。
+
+##### 1.1.4 连接验证
+
+```bash
+# 快速检查 MongoDB 是否接受连接
+docker exec -it mongodb mongosh \
+  -u coslight -p "coslight@tj" --authenticationDatabase admin \
+  --eval "db.adminCommand({ ping: 1 })"
+
+# 列出所有数据库（确认服务正常）
+docker exec -it mongodb mongosh \
+  -u coslight -p "coslight@tj" --authenticationDatabase admin \
+  --eval "show dbs"
+```
+
+##### 1.1.5 初始化 eventdb 数据库
+
+MongoDB 启动后进入容器，为 `eventdb` 库授权：
+
+```bash
+docker exec -it mongodb mongosh \
+  -u coslight -p "coslight@tj" --authenticationDatabase admin
+```
+
+在 `mongosh` 中执行：
+
+```javascript
+// 切换到 eventdb，若不存在则自动创建
+use eventdb
+
+// 授予 coslight 用户对 eventdb 的读写权限（根用户已有全库权限，此步可选）
+db.createUser({
+  user: "coslight",
+  pwd:  "coslight@tj",
+  roles: [{ role: "readWrite", db: "eventdb" }]
+})
+```
+
+#### 1.2 K8s 部署（Minikube）
+
+YAML 文件位于 `deploy/k8s/`（从 modelrt 仓库迁移而来，需确认文件已拷贝至本项目）。
+
+```bash
+kubectl apply -f deploy/k8s/mongodb-secret.yaml
+kubectl apply -f deploy/k8s/mongodb-pvc.yaml
+kubectl apply -f deploy/k8s/mongodb-statefulset.yaml
+kubectl apply -f deploy/k8s/mongodb-service.yaml
+```
+
+| 参数 | 值 | 说明 |
+| :--- | :--- | :--- |
+| **镜像** | `mongo:7.0` | MongoDB 7.0 |
+| **NodePort** | `30017` | 集群外访问端口 |
+| **用户名** | `admin` | Root 管理员（Secret `mongodb-secret`） |
+| **密码** | `coslight` | Secret `mongodb-secret` 中配置，生产环境请替换强密码 |
+| **存储** | `2Gi` | PVC `mongodb-data` |
+| **CPU** | `100m` 请求 / `500m` 上限 | StatefulSet `resources` 字段 |
+| **内存** | `256Mi` 请求 / `512Mi` 上限 | StatefulSet `resources` 字段 |
+
+> **注意：** 密码存储在 `mongodb-secret.yaml` 的 `stringData` 中，生产环境应替换为强密码，并避免将明文密码提交至版本库。
+
+##### 1.2.1 等待 Pod 就绪
+
+```bash
+kubectl wait --for=condition=ready pod -l app=mongodb --timeout=120s
+```
+
+##### 1.2.2 连接验证
+
+```bash
+kubectl exec -it $(kubectl get pod -l app=mongodb -o jsonpath='{.items[0].metadata.name}') \
+  -- mongosh -u admin -p coslight --authenticationDatabase admin \
+  --eval "db.adminCommand({ ping: 1 })"
+```
+
+##### 1.2.3 初始化 eventdb 数据库
+
+```bash
+kubectl exec -it $(kubectl get pod -l app=mongodb -o jsonpath='{.items[0].metadata.name}') \
+  -- mongosh -u admin -p coslight --authenticationDatabase admin
+```
+
+在 `mongosh` 中执行：
+
+```javascript
+use eventdb
+
+db.createUser({
+  user: "coslight",
+  pwd:  "coslight@tj",
+  roles: [{ role: "readWrite", db: "eventdb" }]
+})
+```
+
+##### 1.2.4 状态检查
+
+```bash
+kubectl get pods -l app=mongodb
+kubectl logs -l app=mongodb --tail=30
+```
+
+---
+
+### 2\. 部署 RabbitMQ（Kubernetes）
+
+RabbitMQ 配置为仅允许 TLS 连接（`listeners.tcp = none`），所有客户端须持有由同一 CA 签发的证书。YAML 文件位于 `deploy/mq/`。
+
+#### 2.1 TLS 证书生成
+
+##### 2.1.1 生成根 CA
+
+```bash
+git clone https://github.com/rabbitmq/tls-gen.git
+cd tls-gen/basic
+
+# 生成根 CA，结果输出至 result/
+make CN=rabbitmq-server
+# ca_certificate.pem 与 ca_key.pem（即 cakey.pem）生成于 result/
+```
+
+##### 2.1.2 生成服务端证书
+
+服务端证书需包含 SAN，使其同时匹配集群内 DNS 和 Minikube IP。使用 `deploy/mq/server.conf`（已预置正确配置）：
+
+```bash
+# 将 ca_certificate.pem 和 cakey.pem 放在当前目录
+openssl genrsa -out server_key.pem 2048
+
+openssl req -new -key server_key.pem \
+    -out server_cert.csr -config deploy/mq/server.conf
+
+openssl x509 -req -in server_cert.csr \
+    -CA ca_certificate.pem -CAkey cakey.pem -CAcreateserial \
+    -out server_certificate.pem -days 730 -sha256 \
+    -extfile deploy/mq/server.conf -extensions v3_server
+
+rm server_cert.csr
+```
+
+##### 2.1.3 生成 EventRT 客户端证书
+
+CN 必须与 RabbitMQ 中注册的用户名一致（`eventrt-client`）。使用 `deploy/mq/eventrt.conf`：
+
+```bash
+openssl genrsa -out eventrt_client_key.pem 2048
+
+openssl req -new -key eventrt_client_key.pem \
+    -out eventrt_client.csr -config deploy/mq/eventrt.conf
+
+openssl x509 -req -in eventrt_client.csr \
+    -CA ca_certificate.pem -CAkey cakey.pem -CAcreateserial \
+    -out eventrt_client_cert.pem -days 365 \
+    -extensions v3_client -extfile deploy/mq/eventrt.conf
+
+rm eventrt_client.csr
+```
+
+##### 2.1.4 生成 ModelRT 客户端证书
+
+使用 `deploy/mq/modelrt.conf`（CN 为 `modelrt-client`）：
+
+```bash
+openssl genrsa -out modelrt_client_key.pem 2048
+
+openssl req -new -key modelrt_client_key.pem \
+    -out modelrt_client.csr -config deploy/mq/modelrt.conf
+
+openssl x509 -req -in modelrt_client.csr \
+    -CA ca_certificate.pem -CAkey cakey.pem -CAcreateserial \
+    -out modelrt_client_cert.pem -days 365 \
+    -extensions v3_client -extfile deploy/mq/modelrt.conf
+
+rm modelrt_client.csr
+```
+
+##### 2.1.5 验证证书
+
+```bash
+# 验证服务端证书
+openssl verify -CAfile ca_certificate.pem server_certificate.pem
+
+# 验证客户端证书
+openssl verify -CAfile ca_certificate.pem eventrt_client_cert.pem
+openssl verify -CAfile ca_certificate.pem modelrt_client_cert.pem
+
+# 确认 CN 和扩展（clientAuth / serverAuth）
+openssl x509 -in server_certificate.pem -noout -subject -ext subjectAltName
+openssl x509 -in eventrt_client_cert.pem -noout -subject -text | grep -A1 "Extended Key Usage"
+openssl x509 -in modelrt_client_cert.pem -noout -subject
+```
+
+#### 2.2 部署 RabbitMQ
+
+##### 2.2.1 创建证书 Secret
+
+在证书文件所在目录执行：
+
+```bash
+sh deploy/mq/secert.sh
+```
+
+该脚本等价于：
+
+```bash
+kubectl create secret generic rabbitmq-certs \
+  --from-file=ca_certificate.pem=./certs/ca_certificate.pem \
+  --from-file=server_certificate.pem=./certs/server_certificate.pem \
+  --from-file=server_key.pem=./certs/server_key.pem
+```
+
+##### 2.2.2 部署
+
+```bash
+kubectl apply -f deploy/mq/rabbitmq-secret.yaml
+kubectl apply -f deploy/mq/rabbitmq-users-config.yaml
+kubectl apply -f deploy/mq/rabbitmq-config.yaml
+kubectl apply -f deploy/mq/rabbitmq-deployment.yaml
+kubectl apply -f deploy/mq/rabbitmq-service.yaml
+```
+
+##### 2.2.3 端口汇总
+
+| 端口 | NodePort | 说明 |
+| :--- | :--- | :--- |
+| `5671` | `30671` | AMQP over TLS（客户端连接） |
+| `5672` | `30672` | AMQP 明文（内部备用，生产禁用） |
+| `15671` | `31671` | Management UI over TLS |
+| `15672` | `31672` | Management UI 明文（内部备用） |
+
+##### 2.2.4 用户与权限说明
+
+用户定义在 `rabbitmq-users-config.yaml` 的 `definitions.json` 中，启动时通过 `load_definitions` 自动加载：
+
+| 用户 | 认证方式 | 权限 | 说明 |
+| :--- | :--- | :--- | :--- |
+| `coslight` | 密码 | administrator | 管理员，密码在 `rabbitmq-secret.yaml` |
+| `eventrt-client` | X.509 证书（CN） | configure/read/write | EventRT 服务专用 |
+| `modelrt-client` | X.509 证书（CN） | configure/read/write | ModelRT 服务专用 |
+| `web-client` | X.509 证书（CN） | read/write | Web 客户端 |
+
+> **注意：** 证书认证用户的 `password_hash` 留空；RabbitMQ 通过 `ssl_cert_login_from = common_name` 将证书 CN 映射为用户名。
+
+---
+
+### 3\. 部署 EventRT（Kubernetes）
+
+所有资源部署在 `default` 命名空间，YAML 文件位于 `deploy/k8s/`。
+
+#### 3.1 构建并推送镜像
+
+镜像采用三阶段构建，最终基于 `scratch`：
+
+| 阶段 | 基础镜像 | 作用 |
+| :--- | :--- | :--- |
+| **builder** | `golang:1.26-alpine` | 编译 Go 二进制（`CGO_ENABLED=0`，`-trimpath -ldflags="-s -w"`） |
+| **certs** | `alpine:3.21` | 提取 CA 证书、时区数据及非 root 用户定义（UID 默认 `1000`） |
+| **runtime** | `scratch` | 仅含可执行文件与运行时依赖，无 shell、无包管理器 |
+
+**方式一：从源码构建并加载**
+
+```bash
+# 在项目根目录执行（默认运行用户 UID=1000）
+docker build -f deploy/dockerfile/eventrt.Dockerfile -t coslight/eventrt:latest .
+
+# 自定义运行用户 UID
+docker build -f deploy/dockerfile/eventrt.Dockerfile \
+  --build-arg USER_ID=2000 \
+  -t coslight/eventrt:latest .
+
+# 加载到 Minikube（无需私有仓库）
+minikube image load coslight/eventrt:latest
+```
+
+**方式二：直接加载已有本地镜像**
+
+Ubuntu 宿主机上已存在构建好的镜像（如 `eventrt:v1`）时，无需重新构建，直接导入 Minikube：
+
+```bash
+# 确认本地镜像存在
+docker images eventrt:v1
+
+# 加载到 Minikube
+minikube image load eventrt:v1
+
+# 验证镜像已进入 Minikube 缓存
+minikube image ls | grep eventrt
+```
+
+> **注意：** `deploy/k8s/eventrt-deployment.yaml` 中的 `image` 字段需与加载的镜像名称一致，并将 `imagePullPolicy` 设为 `Never`，防止 Minikube 尝试从远端拉取。
+
+#### 3.1.1 镜像冒烟测试
+
+```bash
+# 查看镜像大小（scratch 镜像预期 ≤ 25 MB）
+docker images coslight/eventrt:latest
+
+# 检查镜像元信息（确认 User、Cmd、架构）
+docker inspect coslight/eventrt:latest
+
+# 验证二进制可执行（无 config 时程序报错退出属预期行为，说明镜像构建正常）
+docker run --rm coslight/eventrt:latest
+
+# 挂载示例配置做完整启动验证（Ctrl+C 退出）
+docker run --rm \
+  -v "$(pwd)/configs/config.example.yaml:/app/configs/config.yaml" \
+  -p 8081:8081 \
+  coslight/eventrt:latest
+```
+
+> **注意：** `scratch` 镜像不含 shell，无法使用 `docker exec` 进入容器调试；如需排查问题，可临时将最终阶段改为 `alpine` 进行本地调试，确认后再切回 `scratch`。
+
+#### 3.2 创建客户端证书 Secret
+
+在 RabbitMQ TLS 证书生成完成后（见 2.1），进入证书文件所在目录执行：
+
+```bash
+sh deploy/k8s/eventrt-certs-secret.sh
+```
+
+该脚本等价于：
+
+```bash
+kubectl create secret generic eventrt-certs \
+  --from-file=ca_certificate.pem=./ca_certificate.pem \
+  --from-file=eventrt_client_cert.pem=./eventrt_client_cert.pem \
+  --from-file=eventrt_client_key.pem=./eventrt_client_key.pem
+```
+
+#### 3.3 部署
+
+```bash
+kubectl apply -f deploy/k8s/eventrt-secret.yaml
+kubectl apply -f deploy/k8s/eventrt-configmap.yaml
+kubectl apply -f deploy/k8s/eventrt-deployment.yaml
+kubectl apply -f deploy/k8s/eventrt-service.yaml
+```
+
+等待 Pod 就绪：
+
+```bash
+kubectl wait --for=condition=ready pod -l app=eventrt --timeout=120s
+```
+
+#### 3.4 配置说明
+
+| 配置项 | 方式 | 说明 |
+| :--- | :--- | :--- |
+| `mongodb.password` | Secret `eventrt-secret` | 不写入 ConfigMap，通过环境变量 `MONGODB_PASSWORD` 注入 |
+| `service.secret_key` | Secret `eventrt-secret` | 不写入 ConfigMap，通过环境变量 `SERVICE_SECRET_KEY` 注入 |
+| RabbitMQ 客户端证书 | Secret `eventrt-certs` | 挂载至 `/app/configs/certs/` |
+| `config.yaml` 其余配置 | ConfigMap `eventrt-config` | `rabbitmq.host` 已设为 K8s Service 名 `rabbitmq-service` |
+| `K8S_NAMESPACE` / `K8S_NODE_NAME` | Downward API | 注入至日志全局字段 |
+
+#### 3.5 状态检查
+
+```bash
+# 查看 Pod 状态
+kubectl get pods -l app=eventrt
+
+# 查看启动日志
+kubectl logs -l app=eventrt --tail=50
+
+# 查看 Service
+kubectl get svc eventrt-service
+```
+
+#### 3.6 端口汇总
+
+| NodePort | 说明 |
+| :--- | :--- |
+| `30081` | EventRT HTTP API |
+
+#### 3.7 清理
+
+```bash
+kubectl delete -f deploy/k8s/eventrt-service.yaml \
+               -f deploy/k8s/eventrt-deployment.yaml \
+               -f deploy/k8s/eventrt-configmap.yaml \
+               -f deploy/k8s/eventrt-secret.yaml
+kubectl delete secret eventrt-certs
+```
+

+
+### 4\. Mac 本地访问（SSH 隧道）
+
+`EventRT` 在 Mac 本地运行时，RabbitMQ 部署在 Ubuntu 宿主机（`192.168.1.101`）的 Minikube 中，MongoDB 直接运行在宿主机上。需通过 SSH 本地端口转发建立访问隧道。
+
+#### 4.1 网络拓扑
+
+```text
+Mac 本地端口  ──SSH隧道──▶  Ubuntu 宿主机 (192.168.1.101)  ──▶  Minikube NodePort (192.168.49.2)
+                                       └──▶  MongoDB Docker (宿主机 27017)
+```
+
+#### 4.2 建立隧道
+
+```bash
+ssh -L 27017:127.0.0.1:27017 \
+    -L 5671:192.168.49.2:30671 \
+    -L 15671:192.168.49.2:31671 \
+    -L 4318:192.168.49.2:31318 \
+    -L 16686:192.168.49.2:31686 \
+    douxu@192.168.1.101
+```
+
+如需后台静默运行（不占用终端）：
+
+```bash
+ssh -fN \
+    -L 27017:127.0.0.1:27017 \
+    -L 5671:192.168.49.2:30671 \
+    -L 15671:192.168.49.2:31671 \
+    -L 4318:192.168.49.2:31318 \
+    -L 16686:192.168.49.2:31686 \
+    douxu@192.168.1.101
+```
+
+#### 4.3 端口映射说明
+
+| Mac 本地端口 | 目标 | 服务 | 说明 |
+| :--- | :--- | :--- | :--- |
+| `27017` | 宿主机 `127.0.0.1:27017` | MongoDB | EventRT 事件数据库 |
+| `5671` | Minikube `192.168.49.2:30671` | RabbitMQ AMQP | 消息队列 mTLS 连接 |
+| `15671` | Minikube `192.168.49.2:31671` | RabbitMQ Management | 管理界面 `http://localhost:15671` |
+| `4318` | Minikube `192.168.49.2:31318` | OTLP HTTP | OTel Trace 上报（Jaeger Collector） |
+| `16686` | Minikube `192.168.49.2:31686` | Jaeger UI | 链路追踪查询 `http://localhost:16686` |
+
+> **注意：** 隧道建立后，本地 `config.yaml` 中所有服务地址填 `localhost:<本地端口>` 即可直接运行服务。
+
+#### 4.4 关闭隧道
+
+前台运行时直接 `Ctrl+C`；后台运行时查找并终止进程：
+
+```bash
+# 找到 ssh 隧道进程
+ps aux | grep "ssh -fN"
+# 终止（替换为实际 PID）
+kill <PID>
+```
+
+---
+
+### 5\. 本地运行（go run / 二进制）
+
+#### 5.1 配置服务配置文件
+
+将 `configs/config.example.yaml` 复制为 `configs/config.yaml` 并按以下说明调整：
+
+##### 5.1.1 配置参数说明
+
+| 类别 | 参数名 | 作用描述 | 示例值 |
+| :--- | :--- | :--- | :--- |
+| **MongoDB** | `host` | MongoDB 服务器地址 | `"localhost"` |
+| | `port` | MongoDB 端口 | `27017` |
+| | `user` | 连接用户名 | `"coslight"` |
+| | `password` | 连接密码 | `"coslight@tj"` |
+| | `database` | 业务数据库名 | `"eventdb"` |
+| | `auth_db` | 鉴权数据库 | `"admin"` |
+| | `timeout` | 连接超时（秒） | `10` |
+| **RabbitMQ** | `host` | RabbitMQ 服务器地址 | `"localhost"` |
+| | `port` | AMQP over TLS 端口 | `5671` |
+| | `server_name` | TLS SNI / 证书 CN | `"rabbitmq-server"` |
+| | `ca_cert_path` | CA 证书路径 | `"./configs/certs/ca_certificate.pem"` |
+| | `client_cert_path` | 客户端证书路径 | `"./configs/certs/eventrt_client_cert.pem"` |
+| | `client_key_path` | 客户端私钥路径 | `"./configs/certs/eventrt_client_key.pem"` |
+| | `insecure_skip_verify` | 是否跳过证书校验（开发临时用） | `false` |
+| **Logger (Zap)** | `mode` | 日志模式 `development` / `production` | `"development"` |
+| | `level` | 最低日志级别 | `"debug"` |
+| | `filepath` | 日志文件路径（空字符串输出到 stdout） | `""` |
+| | `maxsize` | 单文件最大大小（MB） | `1` |
+| | `maxbackups` | 保留旧文件最大个数 | `5` |
+| | `maxage` | 保留旧文件最大天数 | `30` |
+| | `compress` | 是否压缩备份文件 | `false` |
+| **Service** | `service_addr` | HTTP 监听地址 | `":8081"` |

+
+#### 5.2 编译 EventRT 服务
+
+```bash
+go build -o eventrt main.go
+```
+
+#### 5.3 启动服务
+
+```bash
+./eventrt
+```
+
+#### 5.4 检测服务启动日志
+
+控制台输出 `starting EventRT server` 后即代表服务启动成功。
+
+---
+
+### 6\. 排查手册
+
+#### 6.1 证书权限检查
+
+确认客户端证书包含 `TLS Web Client Authentication`：
+
+```bash
+openssl x509 -in configs/certs/eventrt_client_cert.pem -noout -text \
+  | grep -A1 "Extended Key Usage"
+```
+
+预期输出包含 `TLS Web Client Authentication`。
+
+#### 6.2 握手连通性验证
+
+```bash
+openssl s_client -connect localhost:5671 \
+    -cert configs/certs/eventrt_client_cert.pem \
+    -key  configs/certs/eventrt_client_key.pem \
+    -CAfile configs/certs/ca_certificate.pem
+```
+
+预期结果：看到 `Verify return code: 0 (ok)`。
+
+#### 6.3 RabbitMQ 日志检查
+
+连接成功后，RabbitMQ 日志应出现：
+
+```
+connection <xxx>: user 'eventrt-client' authenticated and granted access to vhost '/'
+```
+
+查看 Pod 日志：
+
+```bash
+kubectl logs -l app=rabbitmq --tail=50 | grep eventrt-client
+```
+
+#### 6.4 MongoDB 连通性验证
+
+```bash
+mongosh "mongodb://coslight:coslight@tj@localhost:27017/eventdb?authSource=admin"
+```
+
+预期进入 `mongosh` 提示符，执行 `show collections` 无报错。
+
+---
+
+### 7\. 后续操作（停止与清理）
+
+#### 7.1 本地 Docker 部署清理
+
+适用于第 1 节使用 `docker run` 启动的 MongoDB 容器。
+
+```bash
+# 停止容器
+docker stop mongodb
+
+# 删除容器（容器内数据将同步丢失）
+docker rm mongodb
+```
+
+#### 7.2 本地 go run 运行清理
+
+适用于第 5 节以 `go run` 或编译后二进制方式在本地启动的 EventRT 服务。
+
+前台运行时直接 `Ctrl+C` 终止；后台运行时查找并终止进程：
+
+```bash
+# 终止 go run 启动的进程
+pkill -f "go run main.go"
+
+# 或终止编译后的二进制进程
+pkill eventrt
+```
+
+#### 7.3 K8s(Minikube) 部署清理
+
+适用于第 1.2、2、3 节在 Minikube 中部署的所有资源。
+
+##### 7.3.1 分服务清理
+
+**仅停止（缩容至 0，PVC 数据与 Secret 保留）**
+
+将所有 Deployment 和 StatefulSet 缩容至 0 副本，Pod 停止运行但持久卷数据不删除，之后可直接缩容回 1 恢复服务。
+
+```bash
+# 停止所有 Deployment（EventRT / RabbitMQ）
+kubectl scale deployment eventrt rabbitmq --replicas=0
+
+# 停止 MongoDB StatefulSet（PVC 数据保留）
+kubectl scale statefulset mongodb --replicas=0
+```
+
+恢复时：
+
+```bash
+kubectl scale deployment eventrt rabbitmq --replicas=1
+kubectl scale statefulset mongodb --replicas=1
+```
+
+---
+
+**永久清理（删除所有资源，数据不可恢复）**
+
+按部署顺序反向删除各服务资源：
+
+```bash
+# EventRT 应用
+kubectl delete -f deploy/k8s/eventrt-service.yaml \
+               -f deploy/k8s/eventrt-deployment.yaml \
+               -f deploy/k8s/eventrt-configmap.yaml \
+               -f deploy/k8s/eventrt-secret.yaml
+kubectl delete secret eventrt-certs
+
+# MongoDB
+kubectl delete -f deploy/k8s/mongodb-service.yaml \
+               -f deploy/k8s/mongodb-statefulset.yaml \
+               -f deploy/k8s/mongodb-pvc.yaml \
+               -f deploy/k8s/mongodb-secret.yaml
+
+# RabbitMQ
+kubectl delete -f deploy/mq/rabbitmq-service.yaml \
+               -f deploy/mq/rabbitmq-deployment.yaml \
+               -f deploy/mq/rabbitmq-users-config.yaml \
+               -f deploy/mq/rabbitmq-config.yaml \
+               -f deploy/mq/rabbitmq-secret.yaml
+kubectl delete secret rabbitmq-certs
+```
+
+##### 7.3.2 一键清理
+
+> **注意：** 此操作会删除 `deploy/k8s/` 和 `deploy/mq/` 下所有 YAML 对应的 K8s 资源，请确认后执行。
+
+```bash
+kubectl delete -f deploy/k8s/ -f deploy/mq/
+kubectl delete secret eventrt-certs rabbitmq-certs
+```

+# eventRT 事件流转与存储分析
+
+## 一、整体架构
+
+```bash
+modelRT 服务
+    │
+    │ 发布事件 (AMQPS + mTLS)
+    ▼
+RabbitMQ (exchange: event-exchange)
+    │ routing key: event.#.updown.*
+    ▼
+Queue: event-up-down-queue
+    │
+    ▼
+eventRT (消费者)
+    │
+    │ 解析 + 写入
+    ▼
+MongoDB (eventdb.alarms)
+```
+
+---
+
+## 二、事件数据结构 (`event/event.go`)
+
+| 字段 | 类型 | 说明 |
+| :--- | :--- | :--- |
+| `event` | string | 事件名称 |
+| `event_uuid` | string | 唯一标识符 |
+| `type` | int | 事件类型 |
+| `priority` | int | 优先级 0-9 |
+| `status` | int | 事件状态（见第四节） |
+| `category` | string | 可选模板参数 |
+| `timestamp` | int64 | 毫秒级 Unix 时间戳 |
+| `from` | string | 来源：station / platform / msa |
+| `condition` | map | 触发条件（如阈值、当前值） |
+| `attached_subscriptions` | []any | 关联订阅信息 |
+| `result` | map | 事件分析结果 |
+| `operations` | []OperationRecord | 操作历史（见第四节） |
+| `origin` | map | 子站原始告警数据 (CIM Alarm) |
+
+`OperationRecord` 结构：
+
+```go
+Action string  // 动作类型，如 "acknowledgment"
+Op     string  // 操作人标识
+TS     int64   // 操作时间（毫秒）
+```
+
+---
+
+## 三、事件流转流程 (`event/up_down_limit_alarm.go`)
+
+```bash
+main.go 启动
+  └─ go event.ReceiptUpDownLimitAlarm(ctx)       // goroutine 异步运行
+
+ReceiptUpDownLimitAlarm():
+  1. GetConn()                                    // 获取全局 RabbitMQ 连接
+  2. conn.Channel()                               // 创建 Channel
+  3. channel.QueueBind(                           // 绑定路由
+       queue    = "event-up-down-queue",
+       exchange = "event-exchange",
+       key      = "event.#.updown.*"
+     )
+  4. channel.Qos(1, 0, false)                     // 每次只预取 1 条，防止积压
+  5. channel.Consume(autoAck=false)               // 手动 ACK 模式
+  6. for { select msg / ctx.Done() }              // 事件循环
+
+processAlarmEventMessage(msg):
+  1. json.Unmarshal → EventRecord                 // 结构体反序列化
+  2. InsertOne(ctx, alarmEvent)                   // ⚠️ 第一次写入（结构体方式）
+  3. bson.UnmarshalExtJSON → bson.D               // 原始 BSON 反序列化
+  4. InsertOne(ctx, doc)                          // 第二次写入（原始文档方式）
+  5. msg.Ack(false)                               // 手动确认消息
+```
+
+---
+
+## 四、事件状态流转
+
+**现状：`Status` 字段有定义，但无状态常量，无状态机逻辑。**
+
+从 `EventRecord.Status int` + `Operations []OperationRecord` 的设计意图推断，其预期的状态流转应为：
+
+```bash
+[未定义初始态]
+      │
+      │ 由 modelRT 发布事件写入
+      ▼
+   status = ? (活跃/未确认)
+      │
+      │ Operations 中追加 {action: "acknowledgment", op: 用户, ts: 时间}
+      ▼
+   status = ? (已确认)
+      │
+      │ 后续处理（result 填充等）
+      ▼
+   status = ? (已关闭/已解决)
+```
+
+目前**状态码值没有任何枚举常量定义**，`constants/` 包下只有 trace、log_mode、deploy_mode，状态机逻辑尚未实现（代码有多处 `TODO`）。
+
+---
+
+## 五、存储方式
+
+- **数据库**：MongoDB
+- **库/集合**：`eventdb` / `alarms`
+- **写入时机**：消息到达后立即插入，无缓冲
+
+**当前代码存在一个明显问题**（`up_down_limit_alarm.go:99-115`）：
+
+```go
+// 第一次：以结构体插入（会被 Go 零值污染，如 omitempty 未设置的字段）
+mongodbClient.Database("eventdb").Collection("alarms").InsertOne(ctx, alarmEvent)
+
+// 第二次：以原始 BSON 插入（保留原始字段，是更合理的方式）
+mongodbClient.Database(dbName).Collection(collectionName).InsertOne(ctx, doc)
+```
+
+每条消息会**插入两份文档**到 `eventdb.alarms`，且 `msg.Ack` 只在第二次成功后才调用。这是个明显的 TODO 遗留问题，第一次插入应当被删除。
+
+---
+
+## 六、连接可靠性设计
+
+RabbitMQ 连接有自动重连机制（`mq/mq_init.go:82`）：断连后每 5 秒重试一次，直到 context 取消。MongoDB 目前无重连逻辑，直接依赖驱动内置能力。
+
+---
+
+## 七、总结
+
+| 维度 | 现状 |
+| :--- | :--- |
+| 事件流转 | modelRT → RabbitMQ topic exchange → eventRT 消费 → MongoDB |
+| 消息可靠性 | 手动 ACK + QoS=1 + 断连重连 |
+| 存储方式 | MongoDB `eventdb.alarms`，目前每条消息重复写入两次（bug） |
+| 状态流转 | `Status` + `Operations` 字段已建模，但状态常量和状态机**尚未实现** |
+| 主要 TODO | 删除重复插入、定义状态枚举、实现状态流转逻辑、补充推送前端逻辑 |
