+# EFKA 当前代码逻辑梳理
+
+> 本文档记录当前阅读代码后对项目逻辑的理解，主要基于 `apps/efka/src/`、`apps/efka/include/`、`config/` 和 protobuf 生成文件。尚未覆盖每个边界条件和全部测试行为。
+
+## 1. 项目定位
+
+这个项目是一个 Erlang/OTP 应用，核心作用像一个边缘侧 agent：
+
+- 对本机微服务开放 WebSocket 接入，微服务注册、订阅 topic、上报指标。
+- 与上游服务器建立 TLS 长连接，完成鉴权、上报数据、接收远程命令。
+- 通过 Docker API 管理本机容器，包括部署、启动、停止、杀掉、删除、更新配置和列表查询。
+- 用 DETS 做少量本地持久化，包括服务状态和离线缓存包。
+
+依赖主要有：
+
+- `cowboy`：本地 WebSocket server。
+- `gun`：通过 Unix Socket 访问 Docker HTTP API。
+- `ssl`：连接上游 TLS server。
+- OTP `json` 模块：JSON 编解码。
+- `gpb`：protobuf 代码生成。
+
+## 2. 启动流程
+
+应用入口是 `efka_app:start/2`。
+
+启动步骤：
+
+1. 设置 Erlang IO 编码为 unicode。
+2. 设置 `fullsweep_after`，试图加快进程内存回收。
+3. 启动 Cowboy WebSocket server。
+4. 启动顶层 supervisor `efka_sup`。
+
+WebSocket server：
+
+- 从 `config/sys.config` 读取 `efka.websocket_server`。
+- 监听 `/ws`。
+- 请求处理模块是 `efka_service_channel`。
+
+`efka_sup` 启动的子进程：
+
+- `efka_logger`：部署日志落盘。
+- `efka_service_sup`：动态管理每个已注册微服务对应的 `efka_service` 进程。
+- `efka_service_model`：DETS 服务状态表。
+- `efka_subscription`：本地 topic 订阅中心。
+- `efka_iot_client`：连接上游 TLS server 的状态机。
+
+`docker` application 启动的子进程：
+
+- `docker_task_reporter`：部署任务事件缓冲和转发。
+- `docker_deploy_manager`：部署任务管理器。
+
+`docker_events` 代码存在于 `apps/docker`，但目前默认不会启动。
+
+## 3. 两条通信链路
+
+项目里有两条主要通信链路。
+
+### 3.1 微服务到 EFKA：WebSocket
+
+本机微服务连接 `ws://<host>:18080/ws`。
+
+协议处理在 `efka_service_channel`：
+
+- WebSocket 收到 `ping` 直接回复 `pong`。
+- 收到 binary 帧时，第一个字节是帧类型。
+- `FRAME_REQUEST = 0x01`，用 `efka_service_pb` 解码为 `ServiceRequest`。
+- `FRAME_CAST = 0x03`，用 `efka_service_pb` 解码为 `ServiceCast`。
+- 回复时使用 `FRAME_REPLY = 0x02`。
+
+支持的微服务请求：
+
+- `register`：注册服务。
+- `subscribe`：订阅 topic。
+
+支持的微服务 cast：
+
+- `metric_data`：上报指标数据。
+
+注册流程：
+
+1. 微服务发送 `ServiceRequest.Register`，包含 `service_id`。
+2. `efka_service_channel` 调用 `efka_service_sup:start_service(ServiceId)`。
+3. 如果该服务进程不存在，则动态启动一个 `efka_service`；如果已存在，复用已有 pid。
+4. `efka_service_channel` 调用 `efka_service:attach_channel(ServicePid, self())` 绑定当前 WebSocket channel。
+5. `efka_service` 只允许绑定一个存活 channel；已有 channel 存活时返回 `channel exists`。
+6. 注册成功后写入 `efka_service_model`，服务状态设为 running。
+7. channel 退出时，取消全部订阅，并把服务状态改为 stopped。
+
+指标上报流程：
+
+1. 微服务发送 `ServiceCast.MetricData`。
+2. `efka_service_channel` 调用 `efka_service:metric_data(ServicePid, RouteKey, Metric)`。
+3. `efka_service` 转发给 `efka_iot_client:metric_data(RouteKey, Metric)`。
+4. `efka_iot_client` 如果处于 activated 状态，直接发给上游；否则写入持久化 outbox。
+
+### 3.2 EFKA 到上游：TLS 长连接
+
+上游连接逻辑在 `efka_iot_client`，它是一个 `gen_statem`。
+
+状态包括：
+
+- `disconnected`：未连接。
+- `auth`：已连接，等待鉴权响应。
+- `restricted`：鉴权受限，不能正常推送数据，但可以接收部分授权命令。
+- `activated`：已激活，可正常收发。
+
+连接流程：
+
+1. 初始化后立即触发 `create_transport`。
+2. 读取 `efka.tls_server_address`，用 `ssl:connect/4` 建立 TLS 连接。
+3. TLS socket 使用 `{packet, 4}` 和 `{active, true}`。
+4. 连接成功后发送 `AuthRequest`。
+5. 收到鉴权成功 reply 后进入 `activated`，并触发 outbox 刷出。
+6. 连接或鉴权失败时关闭 socket，5 秒后重连。
+
+上游协议同样用第一个字节区分帧类型：
+
+- `FRAME_REQUEST = 0x01`
+- `FRAME_REPLY = 0x02`
+- `FRAME_CAST = 0x03`
+
+但 protobuf 使用的是 `message_pb`，不是微服务侧的 `efka_service_pb`。
+
+`efka_iot_client` 上报的内容：
+
+- `metric_data`：业务指标数据，activated 时实时发送，否则进入持久化 outbox。
+- `task_event_stream`：Docker 部署任务流式日志，只在 activated 时发送。
+- `close_task_event_stream`：任务结束事件，只在 activated 时发送。
+
+`efka_iot_client` 接收的内容：
+
+- `RequestFrame.container_request`：远程容器管理请求，交给 `docker_container_service`。
+- `CastFrame.command`：授权命令，`COMMAND_AUTH` 用于切换鉴权/受限状态。
+- `CastFrame.pub`：上游发布的 topic 消息，交给 `efka_subscription:publish/3`。
+
+## 4. 本地 Pub/Sub 逻辑
+
+`efka_subscription` 是本地订阅中心。
+
+订阅：
+
+- `efka_service_channel` 收到微服务 `subscribe` 后调用 `efka_subscription:subscribe(Topic, self())`。
+- 同一个 pid 对同一个 topic 重复订阅会被忽略。
+- 首次看到某个 subscriber pid 时，会 monitor 该 pid；pid 退出后自动移除订阅。
+
+topic 匹配规则：
+
+- `/` 分隔 topic components。
+- `*` 表示单级匹配。
+- `+` 表示多级匹配，但只能出现在末尾。
+- 完全匹配优先级最高，不过当前代码里的 `order` 字段只是计算并保存，没有实际排序使用。
+
+发布：
+
+- 上游发来的 `CastFrame.Pub` 会调用 `efka_subscription:publish(Topic, Qos, Content)`。
+- 如果匹配到订阅者，向对应 `efka_service_channel` 发送 `{topic_broadcast, Topic, Content}`。
+- `efka_service_channel` 再编码为 `ServiceCast.TopicEvent` 推送给微服务。
+- 如果没有订阅者且 `Qos != 0`，消息会暂存在 `remaining_messages`。
+- 新订阅建立时，会尝试把匹配的 remaining messages 补发给该订阅者。
+
+## 5. Docker 容器管理链路
+
+上游发来的容器请求最终进入 `docker_container_service:handle_request/1`。
+
+支持动作：
+
+- `list`：列出容器。
+- `deploy`：部署容器。
+- `start`：启动容器。
+- `stop`：停止容器。
+- `kill`：发送 kill 信号。
+- `remove`：删除容器。
+- `config`：更新容器配置文件。
+
+简单操作：
+
+- `start/stop/kill/remove/list` 直接调用 `docker_commands`。
+- `docker_commands` 通过短生命周期普通 `docker_client` 进程访问 `/var/run/docker.sock`。
+- HTTP 客户端用 `gun:open_unix/2`。
+- 流式请求使用 `{docker_client, Ref, Event}` 消息返回，事件包括 `{response, Status, Headers}`、`{data, Bin}`、`done` 和 `{error, Reason}`。
+
+部署操作：
+
+1. `docker_container_service` 收到 `deploy` 后调用 `docker_deploy_manager:deploy(TaskId, Params)`。
+2. `docker_deploy_manager` 根据 `docker.root_dir` 和参数里的 `container_name/container_dir` 确保容器目录存在。
+3. 它启动一个独立 `docker_deployer` 进程，并 monitor 该部署进程。
+4. `docker_deployer` 执行实际部署步骤。
+5. 部署过程事件写入 `docker_task_reporter`。
+6. `docker_task_reporter` 在上游连接 activated 时把事件转给 `efka_iot_client`；未激活时保留队列并定时重试。
+
+`docker_deployer` 当前部署步骤：
+
+1. 上报“开始部署容器”。
+2. 调用 `ensure_container_absent/2`，但当前实现只是上报“开始创建容器”，没有真正删除旧容器。
+3. 规范化镜像名，没有 tag 时补 `:latest`。
+4. 调用 Docker API 拉取镜像，`docker_deployer` 按 `Ref` 接收 `docker_client` 流式消息并上报拉取过程。
+5. 创建容器。
+6. 创建空的 `service.conf` 配置文件。
+7. 写部署摘要到 `efka_logger`。
+8. 关闭任务事件流，状态为 `success` 或 `fail`。
+
+创建容器参数：
+
+- `docker_container_builder` 把 protobuf 的 `DockerCreateOptions` 转成 Docker API JSON。
+- 会自动给容器注入环境变量 `CONTAINER_NAME=<name>`。
+- 会自动添加容器内配置路径 `/usr/local/etc/service.conf`。
+- 会自动把宿主机 `service.conf` bind 到容器内 `/usr/local/etc/service.conf`。
+
+配置更新：
+
+- `docker_container_service:update_container_config/2` 根据容器名找到目录。
+- 写入该目录下的 `service.conf`。
+- 容器目录映射由 `docker_helper` 通过 `.container_dir` 指针文件维护。
+
+## 6. 本地持久化
+
+### 6.1 `efka_service_model`
+
+使用 DETS 表 `service`。
+
+文件位置来自 `efka.dets_dir`，默认配置是：
+
+```erlang
+"/usr/local/code/tmp/dets/service.dets"
+```
+
+记录结构在 `apps/efka/include/efka_tables.hrl`：
+
+- `service_id`
+- `container_name`
+- `meta_data`
+- `status`
+- `create_ts`
+- `update_ts`
+
+用途：
+
+- 注册成功时插入或更新服务。
+- channel 关闭时把服务状态改成 stopped。
+- 支持查询所有服务、运行中服务和单个服务状态。
+
+### 6.2 `efka_iot_outbox`
+
+使用 append-only log 文件和 metadata 文件。
+
+作用：
+
+- 当 `efka_iot_client` 不在 activated 状态时，把待上报 packet 缓存下来。
+- `efka_iot_client` 激活后循环 `next -> send -> ack` 刷出。
+- 所有记录 ack 后会截断 log，下一轮从 seq 1 重新开始。
+
+## 7. 日志
+
+有两套日志：
+
+- OTP logger：在 `config/sys.config` 里配置到 console 和 `log/debug.log`。
+- `efka_logger`：自定义部署日志，按日期写到 `code:root_dir() ++ "/log/"` 下。
+
+`efka_logger` 主要用于部署任务摘要和失败原因。
+
+## 8. 配置项
+
+关键配置来自 `config/sys.config`：
+
+- `docker.root_dir`：容器相关目录根路径。
+- `dets_dir`：DETS 文件目录。
+- `websocket_server`：本地 WebSocket 监听配置。
+- `tls_server_address`：上游 TLS server 地址。
+- `auth`：上游鉴权信息。
+
+注意：
+
+- `efka_service_model` 打开 DETS 前假设 `dets_dir` 已存在，代码里没有显式创建目录。
+- `docker_client` 固定使用 `/var/run/docker.sock`，每次请求内部由短生命周期普通进程执行 open/request/close。
+
+## 9. 当前看到的几个注意点
+
+- `README.md` 描述的是 JSON-RPC 风格 WebSocket，但当前代码实际处理的是 binary protobuf 帧；README 可能已经过期。
+- `efka_service_channel` 里 `register` 只使用 `service_id`，没有使用 README 中提到的 `meta_data/container_name`。
+- `efka_iot_client:send_result_reply/3` 和 `send_error_reply/3` 编码 `ReplyFrame` 后没有加 `FRAME_REPLY` 前缀；接收侧是否期望裸 protobuf 需要确认。
+- `docker_deployer:ensure_container_absent/2` 当前没有真正确保旧容器不存在，只是上报日志。
+- `efka_subscription` 计算了 topic `order`，但匹配广播时没有使用优先级排序。
+- `docker_commands` 部分错误响应解码没有统一使用 `[return_maps]`，有些分支可能匹配不到 map。
+- `docker_events` 存在但未启动，且使用 shell 命令 `docker events`，与其他 Docker API 访问方式不同。
+
+## 10. 一句话主流程
+
+微服务通过 WebSocket 注册到 EFKA，本地 channel 把指标交给对应 `efka_service`，再由 `efka_iot_client` 通过 TLS 上报给上游；上游通过同一条 TLS 连接下发 pub/sub 消息和容器管理请求，pub/sub 再广播回本地微服务，容器请求则通过 Docker Unix Socket 在本机执行。

-An OTP application
+## 注意websocket的数据格式为: text
 
-1. 先解决数据的上行问题
-2. todo list
-    要解决连接断开重新连接的问题 !!!
+## 一、模块概述
+`ws_channel` 是基于 Erlang + Cowboy WebSocket 实现的 MQTT 相关交互模块，主要用于服务注册、主题订阅、指标数据上报、事件发送及消息广播等功能，通过 WebSocket 协议实现客户端与服务端的实时双向通信。
 
-Build
------
 
-    $ rebar3 compile
+## 三、核心 API 方法
+客户端通过发送 **JSON 格式文本消息** 与服务端交互，消息格式遵循 JSON-RPC 风格（包含 `id`、`method`、`params` 字段）。
+
+
+### 1. 服务注册（register）
+#### 功能
+注册服务并建立客户端与服务进程的关联，是后续操作（订阅、上报数据等）的前提。
+
+#### 请求格式
+```json
+{
+  "id": <整数，请求唯一标识>,
+  "method": "register",
+  "params": {
+    "service_id": <二进制，服务唯一标识，必填>,
+    "meta_data": <映射，服务元数据，可选>,
+    "container_name": <二进制，容器名称，可选>
+  }
+}
+```
+
+#### 响应格式
+- 成功响应：
+  ```json
+  {
+    "id": <与请求id一致>,
+    "result": "ok"
+  }
+  ```
+- 失败处理：服务端直接关闭连接（因 `attach_channel` 失败）
+
+### 2. 主题订阅（subscribe）
+#### 功能
+订阅指定主题，后续可接收该主题的广播消息。
+
+#### 请求格式
+```json
+{
+  "id": <整数，请求唯一标识>,
+  "method": "subscribe",
+  "params": {
+    "topic": <二进制，订阅的主题名称，必填>
+  }
+}
+```
+
+#### 响应格式
+- 成功响应：
+  ```json
+  {
+    "id": <与请求id一致>,
+    "result": "ok"
+  }
+  ```
+- 失败响应：
+  ```json
+  {
+    "id": <与请求id一致>,
+    "error": {
+      "code": -1,
+      "message": "错误描述"
+    }
+  }
+  ```
+
+#### 处理逻辑
+通过 `efka_subscription:subscribe(Topic, self())` 完成订阅，订阅成功后客户端会收到该主题的广播消息。
+
+
+### 3. 指标数据上报（metric_data）
+#### 功能
+向服务进程上报设备指标数据。
+
+#### 请求格式
+```json
+{
+  "method": "metric_data",
+  "params": {
+    "route_key": <二进制，路由键，必填>,
+    "metric": <指标数据，必填>
+  }
+}
+```
+
+#### 响应处理
+服务端接收后无返回消息（处理逻辑：`efka_service:metric_data(ServicePid, DeviceUUID, RouteKey, Metric)`）
+
+## 五、基础交互协议
+1. **Ping/Pong 心跳**：
+    - 客户端发送 `ping` 消息
+    - 服务端回复 `pong` 消息，维持连接
+
+2. **未知消息处理**：
+    - 客户端发送未定义格式的消息时，服务端记录错误并关闭连接
+
+## 七、典型交互流程
+1. 客户端发起 WebSocket 连接
+2. 客户端发送 `register` 请求完成注册
+3. 客户端发送 `subscribe` 请求订阅目标主题
+4. 客户端通过 `metric_data` 上报指标数据 / 通过 `event` 发送事件
+5. 服务端向客户端推送已订阅主题的消息（`publish` 方法）
+6. 连接关闭（主动断开或异常终止）

+%%% efka_iot_client 的持久化待发送队列。
+%%%
+%%% 本模块用于保存 efka_iot_client 离线期间产生的待发送 packet。底层使用
+%%% 追加写 segment 文件的方式实现。当前场景只有一个写入方和一个读取方，并且
+%%% 读取方每次只读取一条数据。
+%%%
+%%% 文件结构：
+%%% - `segment-N.log'：一个 segment 文件，按写入顺序追加保存 record。
+%%% - `metadata.json'：使用原始 JSON 文本保存 write_seq、acked_seq 和
+%%%   writer_segment。进程启动时仍然会扫描 segment 文件，并以 segment 文件
+%%%   里的真实数据作为准确信息；因此即使 metadata 落后，也不会导致跳过或删除
+%%%   未消费的数据。
+%%% - outbox 目录通过 open/1 的 dir 参数传入，本模块不直接读取应用环境变量。
+%%%
+%%% open/1 参数：
+%%% - dir：outbox 数据目录。
+%%% - segment_record_limit：每个 segment 最多保存的 record 数。
+%%% - max_segments：最多保留的 live segment 数。
+%%% - max_record_bytes：允许读取的单条 record 最大 payload 字节数。
+%%%
+%%% record 格式：
+%%% - 8 字节 magic bytes，当前为 <<"EFKAOBX1">>。
+%%% - 1 字节 version，当前为 1。
+%%% - 1 字节 header size，当前为 22。
+%%% - 4 字节 unsigned big-endian packet size。
+%%% - 8 字节 unsigned big-endian Seq。
+%%% - Packet 原始二进制内容。
+%%% - 4 字节 unsigned big-endian crc32，校验范围为 header + Packet。
+%%% - 读取时会先搜索 magic，再校验 version、header size、packet size 和
+%%%   crc32。遇到损坏 record 时，会继续向后寻找下一个合法 magic，尽量恢复
+%%%   后续可读数据。
+%%%
+%%% 写入逻辑：
+%%% - `append/2' 将一条 record 写入当前 writer segment，随后 fsync 当前
+%%%   segment，推进 write_seq，并持久化 metadata。
+%%% - 每个 segment 最多保存多少条数据由 open/1 的 segment_record_limit
+%%%   参数决定。
+%%% - outbox 最多保留多少个 live segment 由 open/1 的 max_segments 参数
+%%%   决定。当当前 segment 已满，且 live segment 数已经达到上限时，新
+%%%   packet 会被丢弃，已有磁盘数据保持不变。
+%%% - 当当前 segment 已满，但 live segment 数量尚未达到上限时，writer 会
+%%%   关闭旧文件，并开始写入 `segment-(N + 1).log'。
+%%%
+%%% 读取逻辑：
+%%% - `next/1' 找到第一个 end_seq 大于 acked_seq 的 live segment，打开该
+%%%   segment，并只返回第一条 Seq 大于 acked_seq 的 record。
+%%% - 本模块不做批量读取；efka_iot_client 每次只发送并 ack 一条 packet。
+%%% - `ack/2' 接受当前读取到的 Seq。正常情况下 Seq 连续递增；如果某条
+%%%   record 损坏并被读取端跳过，ack 允许推进到后续合法 record 的 Seq，
+%%%   避免单条坏数据阻断整个 segment 后续数据的消费。
+%%%
+%%% segment 清理逻辑：
+%%% - 当 `ack/2' 消费完某个 segment 的最后一条 record，并且后续 segment
+%%%   里还有未读数据时，已消费的 segment 文件会被删除；下一次读取会从后续
+%%%   segment 开始。
+%%% - 当 acked_seq 追上 write_seq 时，说明所有 record 都已经投递完成；此时
+%%%   会删除所有 segment 文件，将计数器重置为 0，下一次 append 从全新的
+%%%   `segment-1.log' 的 Seq 1 开始。

+%%% efka_iot_outbox 的手动模拟测试模块。
+%%%
+%%% 该模块基于 gen_server 实现，用两个定时 tick 模拟一边写入、一边读取：
+%%% - write_tick 每次向 efka_iot_outbox 写入一条 packet。
+%%% - read_tick 每次从 efka_iot_outbox 读取并 ack 一条 packet。
+%%% - 默认 read_interval = write_interval * 2，因此读取速度是写入速度的
+%%%   50%。
+%%% - 读取到的数据会通过 logger:debug/2 输出。
+%%%
+%%% 默认使用独立临时 dir，避免污染真实运行目录。也可以通过 start_link/1
+%%% 传入 {dir, Dir} 指定 outbox 目录。
+%%%
+%%% 示例：
+%%% <pre>
+%%% efka_iot_outbox_test:start_link([
+%%%     {dir, "/private/tmp/efka_iot_outbox_test"},
+%%%     {write_interval, 100},
+%%%     {read_interval, 200},
+%%%     {max_writes, 1000}
+%%% ]).
+%%% efka_iot_outbox_test:stats().
+%%% efka_iot_outbox_test:stop().

+# IOT 容器命令到 Docker JSON 的转换说明
+
+本文档描述 `efka` 收到 `iot` 下发的容器管理 command 后，接受的 Erlang map 格式，以及 deploy 命令中 `create` 参数如何转换成 Docker Engine API 接收的 JSON。
+
+对应代码：
+
+- command 接收入口：[src/iot/efka_iot_client.erl](/usr/local/code/cloudkit/efka/apps/efka/src/iot/efka_iot_client.erl:177)
+- 部署任务管理：[docker_deploy_manager.erl](/usr/local/code/cloudkit/efka/apps/docker/src/docker_deploy_manager.erl:36)
+- 部署执行：[docker_deployer.erl](/usr/local/code/cloudkit/efka/apps/docker/src/docker_deployer.erl:39)
+- Docker JSON 构造：[docker_container_builder.erl](/usr/local/code/cloudkit/efka/apps/docker/src/docker_container_builder.erl:14)
+- Docker API 调用：[docker_commands.erl](/usr/local/code/cloudkit/efka/apps/docker/src/docker_commands.erl:36)
+
+## 1. 协议入口
+
+`iot` 通过 TLS 长连接向 `efka` 下发容器命令：
+
+```erlang
+{<<"command">>, Ref, {<<"container">>, CommandMap}}
+```
+
+`efka` 执行后回复：
+
+```erlang
+{<<"command_response">>, Ref, {<<"container">>, Reply}}
+```
+
+`Reply` 取值：
+
+```erlang
+<<"ok">>
+{<<"ok">>, Result}
+{<<"error">>, Reason}
+```
+
+`Ref` 是 `crypto:strong_rand_bytes(16)` 生成的 16 字节 binary。网络帧只使用 `binary_to_term(PacketBin, [safe])` 可解码的 safe term；协议 label、业务 label、map key 和 action 都使用 binary。
+
+只有 `efka_iot_client` 处于 `activated` 状态时，容器命令才会正常执行；处于非 activated 状态时会返回错误。
+
+## 2. 容器命令 map
+
+`efka_iot_client` 收到网络协议里的 binary-key `CommandMap` 后，直接按 binary key 和 binary action 做函数参数匹配，不再做整包 atom-key 转换。
+
+- command 顶层、`target`、deploy `params`、`create` 中间结构都使用 binary key。
+- `<<"action">>` 的取值使用 binary：`<<"list">>`、`<<"deploy">>`、`<<"start">>`、`<<"stop">>`、`<<"kill">>`、`<<"remove">>`、`<<"config">>`。
+- `undefined` 作为 Erlang 已有 atom 可以直接出现在 safe term 中；协议不再使用额外的哨兵 binary 表示缺省值。
+
+下面各小节描述的是 `efka` 直接接收和处理的 map 格式。
+
+### list
+
+```erlang
+#{<<"action">> => <<"list">>}
+```
+
+执行：
+
+```erlang
+docker_commands:get_containers()
+```
+
+Docker API：
+
+```http
+GET /containers/json?all=true
+```
+
+### deploy
+
+```erlang
+#{
+    <<"action">> => <<"deploy">>,
+    <<"task_id">> => TaskId,
+    <<"params">> => Params
+}
+```
+
+执行：
+
+```erlang
+docker_deploy_manager:deploy(TaskId, Params)
+```
+
+`deploy/2` 会启动独立部署进程，HTTP command response 只表示部署任务是否成功启动。实际部署过程和结果通过 `task_event` 消息流上报给 `iot`。
+
+### start
+
+```erlang
+#{
+    <<"action">> => <<"start">>,
+    <<"target">> => Target
+}
+```
+
+执行：
+
+```erlang
+docker_commands:start_container(ContainerNameOrId)
+```
+
+Docker API：
+
+```http
+POST /containers/{name_or_id}/start
+```
+
+### stop
+
+```erlang
+#{
+    <<"action">> => <<"stop">>,
+    <<"target">> => Target,
+    <<"timeout_seconds">> => TimeoutSeconds
+}
+```
+
+执行：
+
+```erlang
+docker_commands:stop_container(ContainerNameOrId, TimeoutSeconds)
+```
+
+Docker API：
+
+```http
+POST /containers/{name_or_id}/stop?t={TimeoutSeconds}
+```
+
+### kill
+
+```erlang
+#{
+    <<"action">> => <<"kill">>,
+    <<"target">> => Target,
+    <<"signal">> => Signal
+}
+```
+
+执行：
+
+```erlang
+docker_commands:kill_container(ContainerNameOrId, Signal)
+```
+
+### remove
+
+```erlang
+#{
+    <<"action">> => <<"remove">>,
+    <<"target">> => Target,
+    <<"force">> => Force,
+    <<"remove_volumes">> => RemoveVolumes
+}
+```
+
+执行：
+
+```erlang
+docker_commands:remove_container(ContainerNameOrId, Force, RemoveVolumes)
+```
+
+### config
+
+```erlang
+#{
+    <<"action">> => <<"config">>,
+    <<"target">> => Target,
+    <<"config">> => Config
+}
+```
+
+执行：
+
+```erlang
+docker_helper:update_container_config(ContainerNameOrId, iolist_to_binary(Config))
+```
+
+该命令不会调用 Docker API，只会更新 `efka` 主机上对应容器目录里的 `service.conf`。
+
+## 3. Target 解析规则
+
+`target` 是 map：
+
+```erlang
+#{
+    <<"name">> => ContainerName,
+    <<"id">> => ContainerId
+}
+```
+
+解析规则：
+
+- 优先使用 `name`。
+- `name` 为空时使用 `id`。
+- `name` 和 `id` 都为空时会触发匹配错误。
+
+## 4. deploy params 格式
+
+`deploy` 的 `params` 必须包含：
+
+```erlang
+#{
+    <<"container_name">> => ContainerName,
+    <<"create">> => Create
+}
+```
+
+字段说明：
+
+| 字段 | 类型 | 说明 |
+| --- | --- | --- |
+| `container_name` | binary | 容器名称。用于容器创建 URL 的 `name` 参数，也会注入环境变量 `CONTAINER_NAME`。 |
+| `create` | map | Docker create options 的中间结构，由 `iot` 侧构造，`efka` 侧补丁后转为 Docker JSON。 |
+
+`docker_deploy_manager` 会根据 `container_name` 按系统默认规则确保容器目录存在。目录固定为：
+
+```text
+docker.root_dir/container_name/
+```
+
+即使旧客户端在 `params` 中携带 `container_dir`，当前 deploy 流程也会忽略它，避免 HTTP 调用方控制 efka 主机上的写入目录。
+
+## 5. create 中间结构
+
+`create` 的结构：
+
+```erlang
+#{
+    <<"config">> => ContainerConfig,
+    <<"host_config">> => HostConfig,
+    <<"networking_config">> => NetworkingConfig
+}
+```
+
+这三个 map 会被 `docker_container_builder:build_options/3` 转成 Docker Engine API JSON。
+
+## 6. efka 自动补丁规则
+
+在转 Docker JSON 前，`efka` 会先执行补丁：
+
+### 环境变量
+
+向 `create.config.env` 前置注入：
+
+```erlang
+<<"CONTAINER_NAME=", ContainerName/binary>>
+```
+
+如果原 env 列表已经包含完全相同的值，则不会重复添加。
+
+### 配置文件 volume
+
+向 `create.config.volumes` 前置注入容器内配置路径：
+
+```erlang
+<<"/usr/local/etc/service.conf">>
+```
+
+### 配置文件 bind
+
+向 `create.host_config.binds` 前置注入宿主机配置文件映射：
+
+```erlang
+<<ConfigFile/binary, ":/usr/local/etc/service.conf">>
+```
+
+其中 `ConfigFile` 是当前容器目录下的：
+
+```text
+service.conf
+```
+
+如果列表里已存在完全相同的 bind，则不会重复添加。
+
+## 7. Docker JSON 顶层结构
+
+`docker_commands:create_container/2` 最终调用：
+
+```http
+POST /containers/create?name={container_name}
+Content-Type: application/json
+```
+
+请求 body 来自：
+
+```erlang
+Options = docker_container_builder:build_options(ContainerName, ContainerDir, Create),
+Body = iolist_to_binary(json:encode(Options))
+```
+
+最终 JSON 顶层字段：
+
+```json
+{
+  "Image": "...",
+  "Cmd": [],
+  "Entrypoint": [],
+  "Env": [],
+  "Labels": {},
+  "Volumes": {},
+  "User": "",
+  "WorkingDir": "",
+  "Hostname": "",
+  "ExposedPorts": {},
+  "NetworkingConfig": {},
+  "Healthcheck": {},
+  "HostConfig": {}
+}
+```
+
+空列表或空 map 字段有的会保留，有的会被省略到 `{}`，具体见下面映射规则。
+
+## 8. create.config 到 Docker JSON
+
+| 中间字段 | Docker JSON 字段 | 转换规则 |
+| --- | --- | --- |
+| `image` | `Image` | 转成 binary；缺省为 `""`。部署流程拉镜像时会对 image 补 `:latest`，但 create JSON 使用传入值。 |
+| `cmd` | `Cmd` | 列表元素逐个转 binary。 |
+| `entrypoint` | `Entrypoint` | 列表元素逐个转 binary。 |
+| `env` | `Env` | 列表元素逐个转 binary，并自动注入 `CONTAINER_NAME=...`。 |
+| `labels` | `Labels` | key/value 都转 binary。 |
+| `volumes` | `Volumes` | 转成 Docker 要求的 object，key 是容器内路径，value 是 `{}`。 |
+| `user` | `User` | 转成 binary；缺省为 `""`。 |
+| `working_dir` | `WorkingDir` | 转成 binary；缺省为 `""`。 |
+| `hostname` | `Hostname` | 转成 binary；缺省为 `""`。 |
+| `exposed_ports` | `ExposedPorts` | 转成 Docker 端口 object。 |
+| `healthcheck` | `Healthcheck` | 转成 Docker Healthcheck object；未传时为 `{}`。 |
+
+### Volumes
+
+输入：

+]
+```
+
+输出 JSON：
+
+```json
+{
+  "ExposedPorts": {
+    "80/tcp": {},
+    "53/udp": {}
+  }
+}
+```
+
+规则：
+
+- `protocol` 为空或 `<<"tcp">>` 时输出 `tcp`。
+- 其他 protocol 原样输出。
+
+### Healthcheck
+
+该字段由 iot 校验后下发。`test` 必须是 binary list，`interval_ns`、`timeout_ns` 和 `retries` 必须是非负整数；efka 只按收到的中间 map 转成 Docker JSON 字段。
+
+输入：
+
+```erlang
+#{
+    <<"test">> => [<<"CMD-SHELL">>, <<"curl -f http://localhost || exit 1">>],
+    <<"interval_ns">> => 30000000000,
+    <<"timeout_ns">> => 10000000000,
+    <<"retries">> => 3
+}
+```
+
+输出 JSON：
+
+```json
+{
+  "Healthcheck": {
+    "Test": ["CMD-SHELL", "curl -f http://localhost || exit 1"],
+    "Interval": 30000000000,
+    "Timeout": 10000000000,
+    "Retries": 3
+  }
+}
+```
+
+## 9. create.host_config 到 Docker JSON
+
+`host_config` 会被合并到 Docker JSON 的 `HostConfig` 字段。
+
+| 中间字段 | Docker JSON 字段 | 转换规则 |
+| --- | --- | --- |
+| `binds` | `HostConfig.Binds` | 列表元素逐个转 binary，并自动注入 `service.conf` bind。空列表时省略。 |
+| `network_mode` | `HostConfig.NetworkMode` | 空 binary 时省略。 |
+| `restart_policy` | `HostConfig.RestartPolicy` | 转成 `Name` 和可选 `MaximumRetryCount`。 |
+| `privileged` | `HostConfig.Privileged` | 只有 true 时输出。false 时省略。 |
+| `cap_add` / `cap_drop` | `HostConfig.CapAdd` / `HostConfig.CapDrop` | 两者都为空时省略；只要一个非空，两个字段都会输出。 |
+| `devices` | `HostConfig.Devices` | 转成 Docker device object 列表。 |
+| `memory` | `HostConfig.Memory` | 0 时省略。 |
+| `memory_reservation` | `HostConfig.MemoryReservation` | 0 时省略。 |
+| `nano_cpus` | `HostConfig.NanoCpus` | 0 时省略。 |

+| `tmpfs` | `HostConfig.Tmpfs` | 空 map 时省略。 |
+| `sysctls` | `HostConfig.Sysctls` | 空 map 时省略。 |
+| `extra_hosts` | `HostConfig.ExtraHosts` | 空列表时省略。 |

+## 12. 部署流程补充
+
+deploy action 的执行流程：
+
+1. 根据 `container_name` 和 `docker.root_dir` 确保默认容器目录存在。
+2. 启动独立部署进程。
+3. 部署进程上报任务事件流。
+4. 规范化镜像名：如果镜像最后一段没有 tag，则补 `:latest`。
+5. 调用 Docker API 拉取镜像。
+6. 构造 Docker create JSON。
+7. 调用 `POST /containers/create?name={container_name}`。
+8. 创建空 `service.conf` 文件。
+9. 写入部署摘要日志并关闭任务事件流。
+
+注意：当前 `ensure_container_absent/2` 只上报“开始创建容器”，不会删除已有同名容器；如果 Docker 返回名称冲突，部署会失败并上报“本地容器已经存在”。

+# EFKA 与 IOT 交互协议
+
+本文档描述 `efka` 与 `iot` 之间的 TLS 长连接协议。当前协议由 Erlang term 直接序列化，发送端使用 `term_to_binary/1`，接收端使用 `binary_to_term(PacketBin, [safe])`。
+
+协议帧只使用 safe external term：顶层 label、业务 label、map key 使用 binary；`Ref` 使用 `crypto:strong_rand_bytes(16)` 生成，是 16 字节 binary。网络协议里不发送 Erlang `reference()`，也不依赖动态创建 atom。
+
+## 传输层
+
+- `efka` 作为 TLS client 连接 `iot`。
+- `iot` 作为 TLS server 接收多个 `efka` 连接，一个连接对应一个 `ssl_channel` 进程。
+- socket 使用 `{packet, 4}`，每个 Erlang term binary 作为一个完整包发送。
+- `Ref` 使用 `crypto:strong_rand_bytes(16)` 生成，只在当前连接的 inflight 表内匹配。
+
+## 顶层帧
+
+协议顶层 tuple 用来表达交互语义：
+
+```erlang
+{<<"request">>, Ref, Body}
+{<<"response">>, Ref, Reply}
+{<<"command">>, Ref, {Domain, Payload}}
+{<<"command_response">>, Ref, {Domain, Reply}}
+{<<"message">>, Body}
+```
+
+语义说明：
+
+| 帧 | 方向 | 语义 |
+| --- | --- | --- |
+| `{<<"request">>, Ref, Body}` | efka -> iot | efka 发起请求，需要 iot 回复 |
+| `{<<"response">>, Ref, Reply}` | iot -> efka | iot 对 efka request 的回复 |
+| `{<<"command">>, Ref, {Domain, Payload}}` | iot -> efka | iot 下发命令，需要 efka 回复 |
+| `{<<"command_response">>, Ref, {Domain, Reply}}` | efka -> iot | efka 对 iot command 的回复 |
+| `{<<"message">>, Body}` | 双向 | 异步消息，不要求回复 |
+
+`command` 和 `command_response` 的 `Domain` 表示业务域，目前支持：
+
+- `<<"container">>`
+
+## 鉴权请求
+
+初始连接由 `efka` 发起鉴权 request。每条 TLS 连接只允许一次鉴权；`iot` 侧鉴权成功后会在 `ssl_channel` 标记该连接已鉴权，如果同一连接再次发送 `auth_request`，`iot` 会直接关闭连接。
+
+```erlang
+{<<"request">>, Ref, {<<"auth_request">>, #{
+    <<"uuid">> => UUID,
+    <<"token">> => Token,
+    <<"timestamp">> => Timestamp
+}}}
+```
+
+`iot` 回复：
+
+```erlang
+{<<"response">>, Ref, {<<"auth_response">>, <<"ok">>}}
+{<<"response">>, Ref, {<<"auth_response">>, {<<"error">>, {<<"failed">>, Reason}}}}
+```
+
+处理语义：
+
+- `<<"ok">>`：`efka` 进入 `activated` 状态。
+- `{<<"error">>, {<<"failed">>, Reason}}`：鉴权失败，`iot` 返回失败响应后关闭连接；`efka` 进入重连流程。
+
+## 授权控制
+
+`/host/activate` 只修改 `iot` 本地和持久化的 host 授权状态，不再向 `efka` 下发 auth command。`efka` 可以继续保持连接并发送数据，是否处理这些数据由 `iot_host` 当前状态决定。
+
+因此当前协议没有 `{<<"command">>, Ref, {<<"auth">>, ...}}` 和 `{<<"command_response">>, Ref, {<<"auth">>, ...}}`。授权关闭时，`iot_host` 保持 channel 在线，但不处理上报数据；授权重新打开后，已在线的 channel 可以继续使用。
+
+## 容器管理命令
+
+`iot` 对 `efka` 的容器管理使用 command 语义：
+
+```erlang
+{<<"command">>, Ref, {<<"container">>, CommandMap}}
+```
+
+`efka` 回复：
+
+```erlang
+{<<"command_response">>, Ref, {<<"container">>, Reply}}
+```
+
+`Reply` 取值：
+
+```erlang
+<<"ok">>
+{<<"ok">>, Result}
+{<<"error">>, Reason}
+```
+
+`CommandMap` 使用 binary key 和 binary action；`efka` 接收后直接按 binary key/action 匹配，Docker 参数链路继续使用 binary-key map，不再转换成 atom-key map。
+
+### list
+
+```erlang
+#{<<"action">> => <<"list">>}
+```
+
+返回当前 `efka` 主机上的容器列表。
+
+### deploy
+
+```erlang
+#{
+    <<"action">> => <<"deploy">>,
+    <<"task_id">> => TaskId,
+    <<"params">> => Params
+}
+```
+
+触发容器部署。部署过程中的流式日志不通过该 command response 返回，而是通过 `message` 的 `task_event` 上报。
+
+### start
+
+```erlang
+#{
+    <<"action">> => <<"start">>,
+    <<"target">> => Target
+}
+```
+
+### stop
+
+```erlang
+#{
+    <<"action">> => <<"stop">>,
+    <<"target">> => Target,
+    <<"timeout_seconds">> => TimeoutSeconds
+}
+```
+
+### kill
+
+```erlang
+#{
+    <<"action">> => <<"kill">>,
+    <<"target">> => Target,
+    <<"signal">> => Signal
+}
+```
+
+### remove
+
+```erlang
+#{
+    <<"action">> => <<"remove">>,
+    <<"target">> => Target,
+    <<"force">> => Force,
+    <<"remove_volumes">> => RemoveVolumes
+}
+```
+
+### config
+
+```erlang
+#{
+    <<"action">> => <<"config">>,
+    <<"target">> => Target,
+    <<"config">> => Config
+}
+```
+
+更新容器配置文件。
+
+### Target
+
+容器目标使用 map 表示：
+
+```erlang
+#{
+    <<"name">> => ContainerName,
+    <<"id">> => ContainerId
+}
+```
+
+`name` 和 `id` 至少一个非空；优先使用 `name`，`name` 为空时使用 `id`。
+
+## 异步消息
+
+`message` 不带 `Ref`，不要求对端回复。
+
+### efka -> iot: data
+
+```erlang
+{<<"message">>, {<<"data">>, #{
+    <<"route_key">> => RouteKey,
+    <<"metric">> => Metric
+}}}
+```
+
+用于 `efka` 上报业务指标数据。
+
+### efka -> iot: task_event
+
+```erlang
+{<<"message">>, {<<"task_event">>, #{
+    <<"task_id">> => TaskId,
+    <<"type">> => Type,
+    <<"stream">> => Stream
+}}}
+```
+
+任务事件流关闭时：
+
+```erlang
+{<<"message">>, {<<"task_event">>, #{
+    <<"task_id">> => TaskId,
+    <<"type">> => <<"close">>,
+    <<"stream">> => Reason
+}}}
+```
+
+`task_event` 本身不携带 `uuid`。`iot` 在接收该消息时使用当前已鉴权 `ssl_channel` 绑定的 host UUID，把事件路由到内部任务进程 `{UUID, TaskId}`。HTTP 页面通过 SSE 订阅时也必须使用同一组参数：
+
+```http
+GET /event_stream?uuid=<host_uuid>&task_id=<task_id>
+```
+
+`iot` 会为每个 `{UUID, TaskId}` 维护一个独立的任务进程，用于缓存最近的部署日志、支持多个 SSE listener，并在收到 close 事件后结束事件流。
+
+### efka -> iot: ping
+
+```erlang
+{<<"message">>, <<"ping">>}
+```
+
+用于 TLS 长连接的应用层保活。`efka` 在鉴权成功后周期发送，当前发送间隔为 30 秒。
+
+`iot` 收到后回复：
+
+```erlang
+{<<"message">>, <<"pong">>}
+```
+
+`ping/pong` 只表示 TLS 连接仍可读写，不参与 host online/offline 判定。host 上下线仍由 UDP 心跳和 `iot_host` 本地连接状态共同维护。
+
+### iot -> efka: pub
+
+```erlang
+{<<"message">>, {<<"pub">>, #{
+    <<"topic">> => Topic,
+    <<"qos">> => Qos,
+    <<"content">> => Content
+}}}
+```
+
+用于 `iot` 向 `efka` 本地订阅系统发布 topic 消息。
+
+## 状态与超时
+
+- `efka` 鉴权超时时间：5 秒。
+- `iot` command inflight 超时时间：60 秒。
+- `iot` SSL channel 空闲超时时间：120 秒。120 秒内没有收到任何 TLS 包，包括 `ping`、业务 `message`、`request`、`command_response`，`iot` 会主动关闭该连接。
+- `iot` 管理多个 `efka` 时，每个连接有独立 `ssl_channel` 和独立 inflight 表。
+- command 超时后，`iot` 删除 inflight 记录；之后如果迟到的 `command_response` 到达，会被视为未预期响应。
+
+## UDP 心跳
+
+`efka` 通过独立的 `efka_iot_heartbeat` 进程向 `iot` 发送 UDP 心跳。TLS control channel 和 UDP 心跳共用 `iot_server.host`，分别使用 `tls_port` 和 `udp_port`。UDP 心跳包使用 HMAC-SHA256 校验，HMAC key 为 `SHA256(auth.token)`。
+
+详细格式见 [heartbeat.md](heartbeat.md)。
+
+## 兼容性
+
+当前协议不兼容旧 tuple：
+
+- 旧容器管理：`{request, Ref, {container_request, ...}}`
+- 旧容器回复：`{response, Ref, {container_response, ...}}`
+- 旧授权控制：`{message, {auth_control, Command}}`
+- 已移除的 auth command：`{command, Ref, {auth, activate | deactivate}}`
+- 旧 Ref：Erlang `reference()`，例如 `make_ref()` 生成的值。
+
+如果需要滚动升级，应先增加临时兼容分支或引入协议版本协商。

+# UDP 心跳
+
+`efka` 通过独立的 `efka_iot_heartbeat` 进程向 `iot` 发送 UDP 心跳。该心跳只表示主机存活，不依赖 TLS control channel 是否在线。
+
+## 配置
+
+TLS 和 UDP 共用同一个 `iot_server.host`：
+
+```erlang
+{iot_server, [
+  {host, "localhost"},
+  {tls_port, 443},
+  {udp_port, 18080}
+]},
+
+{heartbeat, [
+  {interval, 5000}
+]},
+
+{auth, [
+  {uuid, "qbxmjyzrkpntfgswaevodhluicqzxplkm"},
+  {token, "zpxlkvmqwnbghytrujsdieofazxcvbnm"}
+]}
+```
+
+- `tls_port` 用于 `efka_iot_client` 建立 TLS 连接。
+- `udp_port` 用于 `efka_iot_heartbeat` 发送 UDP 心跳。
+- `heartbeat.interval` 是发送间隔，单位毫秒，默认 5000。
+- UDP 心跳和 TLS 鉴权复用 `auth.uuid` 和 `auth.token`。
+
+## 包格式
+
+```erlang
+<<
+    Version:8,
+    UuidLen:16,
+    UUID:UuidLen/binary,
+    Timestamp:64/unsigned-big,
+    Nonce:16/binary,
+    Mac:32/binary
+>>
+```
+
+`Mac` 使用 HMAC-SHA256：
+
+```erlang
+HeartbeatSecret = crypto:hash(sha256, Token),
+Payload = <<Version:8, UuidLen:16, UUID:UuidLen/binary, Timestamp:64/unsigned-big, Nonce:16/binary>>,
+Mac = crypto:mac(hmac, sha256, HeartbeatSecret, Payload)
+```
+
+其中 `Token` 是 `auth.token`。`iot` 侧注册 efka client 时保存同样的 `SHA256(Token)` 派生值，并用它校验心跳。

+# EFKA 与 Service WebSocket 交互协议
+
+本文档描述部署在 `efka` 主机上的 service 与 `efka` 之间的 WebSocket 通讯逻辑。当前接入实现位于：
+
+- [efka_service_channel.erl](/usr/local/code/cloudkit/efka/apps/efka/src/service/efka_service_channel.erl)
+- [service.proto](/usr/local/code/cloudkit/efka/apps/efka/proto/service.proto)
+- [efka_subscription.erl](/usr/local/code/cloudkit/efka/apps/efka/src/service/efka_subscription.erl)
+- [efka_service.erl](/usr/local/code/cloudkit/efka/apps/efka/src/service/efka_service.erl)
+
+## 1. 连接入口
+
+`efka` 启动时会创建 Cowboy WebSocket server，监听配置来自 `efka.config` 的 `websocket_server`：
+
+```erlang
+{websocket_server, [
+    {port, 18080},
+    {acceptors, 10},
+    {max_connections, 1024},
+    {backlog, 1024}
+]}
+```
+
+WebSocket 路由固定为：
+
+```http
+GET /ws
+```
+
+连接建立后，每个 WebSocket 连接对应一个 `efka_service_channel` 进程。
+
+当前协议没有独立的认证字段。service 必须先发送 `register` request 完成注册；未注册前只能处理 `register`，其它 request 会返回 `invalid request`，cast 会被忽略。
+
+Cowboy WebSocket ping 帧由 `efka_service_channel` 直接回复 pong：
+
+```erlang
+websocket_handle(ping, State) -> {reply, pong, State}
+```
+
+## 2. 二进制帧格式
+
+service 与 `efka` 之间使用 WebSocket binary frame。每个业务 frame 的第 1 个字节是自定义帧类型，剩余字节是 protobuf payload。
+
+```text
+<frame_type:1 byte><protobuf_payload:N bytes>
+```
+
+帧类型：
+
+| frame_type | 十六进制 | 方向 | 语义 | protobuf 类型 |
+| --- | --- | --- | --- | --- |
+| `REQUEST` | `0x01` | service -> efka | 请求，需要 efka 回复 | `ServiceRequest` |
+| `REPLY` | `0x02` | efka -> service | request 的响应 | `ServiceReply` |
+| `CAST` | `0x03` | 双向 | 单向消息，不要求回复 | `ServiceCast` |
+
+`efka_service_channel` 当前只处理 service 发来的 `REQUEST` 和 `CAST`。收到未知格式时只记录日志，不主动发送错误响应。
+
+## 3. Protobuf 定义
+
+协议定义来自 `apps/efka/proto/service.proto`：
+
+```protobuf
+syntax = "proto3";
+
+message ServiceRequest {
+  uint32 packet_id = 1;
+
+  message Register {
+    string service_id = 1;
+  }
+
+  message Subscribe {
+    string topic = 1;
+  }
+
+  oneof request {
+    Register register = 10;
+    Subscribe subscribe = 11;
+  }
+}
+
+message ServiceReply {
+  uint32 packet_id = 1;
+
+  message Error {
+    int32 code = 1;
+    string message = 2;
+  }
+
+  oneof reply {
+    bytes result = 10;
+    Error error = 11;
+  }
+}
+
+message ServiceCast {
+  message MetricData {
+    bytes route_key = 1;
+    bytes metric = 2;
+  }
+
+  message TopicEvent {
+    string topic = 1;
+    bytes content = 2;
+  }
+
+  oneof body {
+    TopicEvent topic_event = 10;
+    MetricData metric_data = 11;
+  }
+}
+```
+
+注意：
+
+- `ServiceRequest.packet_id` 由 service 生成，用于匹配 request 和 reply。
+- `ServiceReply.packet_id` 必须等于原 request 的 `packet_id`。
+- `ServiceReply.result` 当前成功值一般为 `<<"ok">>`。
+- `ServiceReply.error.code` 当前失败时统一使用 `-1`。
+- `MetricData.route_key` 和 `MetricData.metric` 是 bytes。
+- `TopicEvent.topic` 是 string，`TopicEvent.content` 是 bytes。
+
+## 4. request/reply 语义
+
+### 4.1 register
+
+service 建立 WebSocket 后应先发送注册请求：
+
+```protobuf
+ServiceRequest {
+  packet_id: 1
+  register {
+    service_id: "service-a"
+  }
+}
+```
+
+WebSocket binary frame：
+
+```text
+0x01 ++ protobuf(ServiceRequest)
+```
+
+`efka` 处理逻辑：
+
+1. `efka_service_channel` 解码 `ServiceRequest`。
+2. 调用 `efka_service_sup:start_service(ServiceId)` 启动或复用 service 进程。
+3. 调用 `efka_service:attach_channel(ServicePid, ChannelPid)` 绑定当前 WebSocket channel。
+4. 通过 `efka_service_model:insert/1` 写入 service 记录：
+
+```erlang
+#service{
+    service_id = ServiceId,
+    container_name = <<>>,
+    status = ?SERVICE_RUNNING,
+    meta_data = #{},
+    create_ts = efka_util:timestamp(),
+    update_ts = efka_util:timestamp()
+}
+```
+
+如果该 `service_id` 是新记录，`status` 会写入 `?SERVICE_RUNNING`。如果该 `service_id` 已存在，当前 `efka_service_model:insert/1` 只更新 `meta_data`、`container_name` 和 `update_ts`，不会覆盖已有 `status`。
+
+5. `efka_service_channel` 状态更新为：
+
+```erlang
+#state{
+    service_id = ServiceId,
+    service_pid = ServicePid,
+    is_registered = true
+}
+```
+
+成功响应：
+
+```protobuf
+ServiceReply {
+  packet_id: 1
+  result: "ok"
+}
+```
+
+WebSocket binary frame：
+
+```text
+0x02 ++ protobuf(ServiceReply)
+```
+
+失败响应：
+
+```protobuf
+ServiceReply {
+  packet_id: 1
+  error {
+    code: -1
+    message: "attach channel failed"
+  }
+}
+```
+
+常见失败场景：
+
+- 同一个 `service_id` 已有存活 channel，`efka_service:attach_channel/2` 返回 `{error, <<"channel exists">>}`。
+- 当前实现对外统一返回 `"attach channel failed"`，详细原因只写日志。
+
+### 4.2 subscribe
+
+注册成功后，service 可以订阅 topic：
+
+```protobuf
+ServiceRequest {
+  packet_id: 2
+  subscribe {
+    topic: "device/*/event"
+  }
+}
+```
+
+`efka` 处理逻辑：
+
+1. 要求当前 channel 已注册，即 `is_registered = true`。
+2. 调用 `efka_subscription:subscribe(Topic, ChannelPid)`。
+3. 订阅成功后，把 topic 加入 `efka_service_channel` 的 `subscribed_topics` 集合。
+
+成功响应：
+
+```protobuf
+ServiceReply {
+  packet_id: 2
+  result: "ok"
+}
+```
+
+失败响应：
+
+```protobuf
+ServiceReply {
+  packet_id: 2
+  error {
+    code: -1
+    message: "invalid topic name"
+  }
+}
+```
+
+未注册时发送 subscribe 会走通用错误：
+
+```protobuf
+ServiceReply {
+  packet_id: 2
+  error {
+    code: -1
+    message: "invalid request"
+  }
+}
+```
+
+## 5. cast 语义
+
+### 5.1 service -> efka: metric_data
+
+service 通过 `CAST` 上报指标数据：
+
+```protobuf
+ServiceCast {
+  metric_data {
+    route_key: "device/a/temp"
+    metric: "{\"value\":23.5}"
+  }
+}
+```
+
+WebSocket binary frame：
+
+```text
+0x03 ++ protobuf(ServiceCast)
+```
+
+`efka` 处理逻辑：
+
+1. `efka_service_channel` 解码 `ServiceCast`。
+2. 要求当前 channel 已注册。
+3. 调用：
+
+```erlang
+efka_service:metric_data(ServicePid, RouteKey, Metric)
+```
+
+4. `efka_service` 再调用：
+
+```erlang
+efka_iot_client:metric_data(RouteKey, Metric)
+```
+
+5. `efka_iot_client` 通过 efka 与 iot 的 TLS 长连接把数据上报给 iot：
+
+```erlang
+{<<"message">>, {<<"data">>, #{
+    <<"route_key">> => RouteKey,
+    <<"metric">> => Metric
+}}}
+```
+
+`metric_data` 是单向消息，service 不会收到 reply。未注册或未知 cast body 会被忽略。
+
+### 5.2 efka -> service: topic_event
+
+当 `iot` 通过 efka 与 iot 的 TLS channel 下发 pub 消息到 `efka` 时，`efka_iot_client` 会调用：
+
+```erlang
+efka_subscription:publish(Topic, Qos, Content)
+```
+
+`efka_subscription` 根据 topic 匹配已订阅的 `efka_service_channel`。匹配成功后向 channel 进程发送：
+
+```erlang
+{topic_broadcast, Topic, Content}
+```
+
+`efka_service_channel` 再推送 WebSocket `CAST` 给 service：
+
+```protobuf
+ServiceCast {
+  topic_event {
+    topic: "device/a/event"
+    content: "payload bytes"
+  }
+}
+```
+
+WebSocket binary frame：
+
+```text
+0x03 ++ protobuf(ServiceCast)
+```
+
+`topic_event` 是单向消息，不要求 service 回复。
+
+## 6. topic 匹配规则
+
+`efka_subscription` 当前使用 `/` 拆分 topic：
+
+```erlang
+binary:split(Topic, <<$/>>, [global])
+```
+
+支持两种通配符：
+
+| 通配符 | 语义 |
+| --- | --- |
+| `*` | 单级匹配，只匹配一个 segment |
+| `+` | 多级匹配，只能出现在最后一段，且至少匹配一个剩余 segment |
+
+示例：
+
+| 订阅 topic | 发布 topic | 是否匹配 |
+| --- | --- | --- |
+| `device/a/temp` | `device/a/temp` | 是 |
+| `device/*/temp` | `device/a/temp` | 是 |
+| `device/*/temp` | `device/a/b/temp` | 否 |
+| `device/+` | `device/a` | 是 |
+| `device/+` | `device/a/temp` | 是 |
+| `device/+` | `device` | 否 |
+
+同一个 `efka_service_channel` 订阅多个 topic 时，同一次 publish 最多投递一次。
+
+## 7. QoS 与遗留消息
+
+`efka_subscription:publish(Topic, Qos, Content)` 中的 `Qos` 影响没有订阅者时的行为：
+
+- `Qos = 0`：没有匹配订阅者时直接丢弃。
+- `Qos /= 0`：没有匹配订阅者时暂存到 `remaining_messages`。
+
+当后续有 service 订阅能匹配这些 topic 时，`efka_subscription` 会把对应遗留消息推送给该 service，并从 `remaining_messages` 移除。
+
+当前 `remaining_messages` 存在内存中，不持久化；`efka` 重启后会丢失。
+
+## 8. 生命周期与清理
+
+### WebSocket channel 关闭
+
+`efka_service_channel:terminate/3` 会执行：
+
+1. 调用 `efka_subscription:unsubscribe_all(ChannelPid)` 清理该 channel 的所有订阅。
+2. 如果 channel 已完成 register，则调用：
+
+```erlang
+efka_service_model:change_status(ServiceId, ?SERVICE_STOPPED)
+```
+
+也就是把 service 状态更新为停止。
+
+### service 进程退出
+
+`efka_service_channel` monitor 绑定的 `efka_service` 进程。如果 service 进程退出，channel 会停止：
+
+```erlang
+websocket_info({'DOWN', _Ref, process, ServicePid, Reason}, State) ->
+    {stop, State#state{service_pid = undefined}}
+```
+
+`efka_service` 同时也 monitor channel。channel 退出时，`efka_service` 会清空自身的 `channel_pid`。
+
+## 9. 完整交互流程
+
+典型流程：
+
+```text

+## 10. 当前限制
+
+- 没有认证字段，service 只通过 `service_id` 注册。
+- `register` 可重复连接同一个 `service_id`，但同一时间只允许一个活跃 channel 绑定到 `efka_service`。
+- request 只支持 `register` 和 `subscribe`。
+- cast 只支持 `metric_data` 和 `topic_event`。
+- `subscribed_topics` 目前只在 `efka_service_channel` 内记录，关闭时实际清理由 `efka_subscription:unsubscribe_all/1` 完成。
+- `efka_subscription` 当前基于列表扫描匹配，订阅规模很大时需要后续优化为索引结构。

+# TODO
+
+## 协议层
+
+### 高优先级
+
+- 将 `message.proto` 收敛为 `efka` 与 `iot` 共用的一份单一事实来源，避免协议定义漂移和双端重复维护。
+
+### 中优先级
+
+- 增强 protobuf 映射和 Docker JSON 生成相关的自动化契约测试。
+
+## Docker 层
+
+### 高优先级
+
+- 将 `docker_commands` 拆分为更清晰的层次：Docker HTTP 客户端、Docker JSON 构造层、以及 efka 本地补丁逻辑。
+- 明确 `docker_task_reporter` 的投递语义；当前只有内存缓冲，还缺少持久化能力和队列上限控制。
+
+### 中优先级
+
+- 丰富 `docker_deploy_manager` 的任务跟踪状态，把部署元数据、耗时、阶段、失败原因等信息纳入统一管理，避免后续再回头重构。
+- 统一 `docker_container_service` 的返回结构，避免调用方分支处理 `ok | {ok, binary()} | {error, binary()}` 这种混合形式。
+- 消除 `docker_commands` 中重复的 Docker HTTP 响应解析逻辑。
+
+### 低优先级
+
+- 对于像 `docker_events.erl` 这样当前未启用的模块，要么清理掉，要么补充说明其保留原因。
+
+## 订阅与通道层
+
+### 高优先级
+
+- 将 `efka_subscription` 当前基于列表扫描的匹配方式替换为更可扩展的索引结构，例如 trie 或基于 ETS 的索引。
+
+### 中优先级
+
+- 继续收敛 `efka_iot_client` 的职责，将传输层状态管理与 request/cast 协议处理进一步拆开。
+- 评估并落实 `efka_service_channel` 中 `subscribed_topics` 集合的用途；如果只是被动保存状态，则应简化。
+
+### 低优先级
+
+- 如果 `efka_iot_client` 的缓存指标量继续增长，可以为缓存刷出增加批量发送或节流机制。
+
+## 基础设施层
+
+### 低优先级
+
+- 如果上传相关能力已经不再属于当前运行时，移除或补充说明残留的启动逻辑，例如 `ensure_upload_dir/0`。
+- 评估是否将 `efka_logger` 与 OTP `logger` 统一，避免长期维护两套日志链路。
