+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# 系统架构
+
+CLICD 由 Go 后端、React 前端和宿主机虚拟化能力组成。
+
+## 后端
+
+后端入口在 `backend/main.go`，HTTP 服务路由集中在 `backend/internal/server/server.go`。主要模块：
+
+- `internal/api`：Web 面板和 `/api/v1` 的 HTTP 接口。
+- `internal/config`：配置和 SQLite 存储。
+- `internal/lxc`：LXC 容器管理。
+- `internal/kvm`：KVM/libvirt 虚拟机管理。
+- `internal/cli`：命令行管理入口。
+- `internal/server`：静态前端嵌入和 HTTP 服务。
+- `internal/version`：版本号。
+
+## 前端
+
+前端入口在 `frontend/src/main.tsx`，页面位于 `frontend/src/pages`，通用组件位于 `frontend/src/components`。
+
+主要页面：
+
+- 控制面板：`Dashboard.tsx`
+- 容器列表：`Containers.tsx`
+- 容器详情：`ContainerDetail.tsx`
+- 镜像管理：`ImageManagement.tsx`
+- 安全告警：`Security.tsx`
+- 快照管理：`Snapshots.tsx`
+- 路由管理：`Routing.tsx`
+- API 集成：`ApiIntegration.tsx`
+- 主机报告：`HostReport.tsx`
+- 子用户管理：`SubUserManagement.tsx`
+
+## 前端嵌入
+
+生产构建时，前端产物会放入 `backend/internal/server/web`，后端通过 Go embed 提供静态文件，并对非 API 路由返回 SPA 入口。
+
+## 接口分层
+
+- `/api/*`：Web 面板和兼容接口。
+- `/api/v1/*`：推荐给外部自动化系统使用的版本化接口。
+- WebSSH 和 WebVNC 使用短期票据后建立 WebSocket 连接。

+# 容器管理
+
+容器管理是 CLICD 的核心模块，覆盖创建、生命周期控制、资源限制、网络映射、流量统计、密码重置和控制台访问。
+
+## 容器列表
+
+列表页用于扫描所有容器状态。管理员可以查看全部容器，子用户只能看到授权范围内的容器。
+
+常见字段包括：
+
+- ID、UUID、名称。
+- 虚拟化类型。
+- 运行状态。
+- IP、IPv6。
+- CPU、内存、磁盘限制。
+- 流量使用量和流量上限。
+- 到期时间。
+
+## 创建容器
+
+创建时需要选择模板，并设置资源配额。批量创建可以通过面板或 API 完成，适合一次性发放多个容器。
+
+```http
+POST /api/v1/containers
+POST /api/v1/batch-create
+```
+
+## 生命周期操作
+
+```http
+POST /api/v1/containers/{id}/start
+POST /api/v1/containers/{id}/stop
+POST /api/v1/containers/{id}/restart
+POST /api/v1/containers/{id}/reinstall
+DELETE /api/v1/containers/{id}/delete
+```
+
+开关机、重装、删除等操作会进入任务队列。调用后可通过 `GET /api/v1/tasks` 查看执行状态。
+
+## 资源与流量
+
+容器详情页支持查看资源用量，调整流量限制、资源限制和到期时间。
+
+```http
+GET /api/v1/containers/{id}/usage
+GET /api/v1/containers/{id}/traffic
+POST /api/v1/containers/{id}/traffic-reset
+PUT /api/v1/containers/{id}/traffic-limit
+PUT /api/v1/containers/{id}/resource-limit
+PUT /api/v1/containers/{id}/expiry
+```
+
+## NAT 端口管理
+
+容器详情页的 NAT 端口管理支持新增、编辑和删除映射。新增和编辑会在弹窗里完成，便于集中填写名称、协议、外部端口和内部端口。
+
+```http
+GET /api/v1/containers/{id}/random-port
+POST /api/v1/containers/{id}/port-mappings
+PUT /api/v1/containers/{id}/port-mappings/{index}
+DELETE /api/v1/containers/{id}/port-mappings/{index}
+```
+
+子用户模式下，管理员可限制子用户只能调整内部端口，避免修改宿主机对外端口和协议。
+
+## 远程控制台
+
+```http
+POST /api/v1/ssh-ticket
+POST /api/v1/vnc-ticket
+```
+
+票据只适合短时间使用，返回后应立即用于 WebSSH 或 WebVNC 连接，不要持久化保存。

+- 路由管理中 NAT 和 IPv6 状态是否符合宿主机预期。
+
+## 2. 下载镜像
+
+进入“镜像管理”，选择需要的模板并下载。宿主机资源较小时，可以优先选择 Alpine、Debian 这类轻量镜像。
+
+镜像下载是异步任务，可以在任务队列中观察进度。
+
+## 3. 创建容器
+
+进入“容器管理”，点击创建：
+
+- 选择虚拟化类型和模板。
+- 设置 CPU、内存、磁盘。
+- 设置流量限制和到期时间。
+- 如果需要外部访问，创建后到容器详情里添加 NAT 端口映射或分配 IPv6。
+
+## 4. 打开终端
+
+容器创建完成后，可以在详情页打开 WebSSH。KVM 虚拟机可使用 WebVNC 查看控制台。
+
+## 5. 分发给子用户
+
+如果需要把某个容器交给其他用户管理，进入“子用户管理”创建访问链接。子用户只会看到被授权的容器，并受到管理员配置的操作范围限制。

+# 升级
+
+CLICD 的安装脚本和 CLI 都围绕 GitHub Release 产物工作。升级前建议先确认当前版本、备份配置和数据库。
+
+## 查看版本
+
+Web 面板侧边栏底部会显示当前版本，也可以访问：
+
+```bash
+curl http://127.0.0.1:8999/api/version
+```
+
+返回示例：
+
+```json
+{
+  "success": true,
+  "data": {
+    "version": "1.1.6"
+  }
+}
+```
+
+## 使用安装脚本升级
+
+安装脚本默认使用最新 Release：
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/MengMengCode/CLICD/main/install.sh | sudo sh
+```
+
+指定版本：
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/MengMengCode/CLICD/main/install.sh | sudo CLICD_VERSION=v1.1.6 sh
+```
+
+## 升级前检查
+
+- 确认 `/root/.clicd/` 或实际配置目录已备份。
+- 确认系统服务没有正在执行关键任务。
+- 如果正在下载镜像或恢复快照，建议等待任务完成后再升级。
+- 升级后检查 `systemctl status clicd` 和 Web 面板版本号。

+# 部署建议
+
+CLICD 可以直接运行在宿主机上，也可以放在反向代理之后。生产环境建议先做好访问控制，再开放给管理员使用。
+
+## 服务暴露
+
+默认 Web 端口为 `8999`：
+
+```text
+http://YOUR_SERVER_IP:8999
+```
+
+建议：
+
+- 仅允许固定管理员 IP 访问。
+- 使用反向代理配置 HTTPS。
+- 不要在公开文档或截图里暴露真实登录地址。
+
+## systemd
+
+常用命令：
+
+```bash
+systemctl status clicd
+systemctl restart clicd
+systemctl enable clicd
+journalctl -u clicd -f
+```
+
+## 防火墙
+
+至少确认：
+
+- 面板端口只对可信来源开放。
+- NAT 映射端口按需开放。
+- SSH 管理端口不与容器映射冲突。
+- IPv6 防火墙规则与 IPv4 同步规划。
+
+## 备份
+
+建议定期备份：
+
+- CLICD 配置目录。
+- SQLite 数据库。
+- 容器配置。
+- 关键容器的快照或外部数据备份。

+# 常见问题
+
+## 安装脚本默认安装哪个版本？
+
+默认安装 GitHub Releases 的最新版本。脚本中默认值是 `CLICD_VERSION=latest`，会下载 `releases/latest` 下的 Linux AMD64 产物。
+
+## 可以固定安装某个版本吗？
+
+可以：
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/MengMengCode/CLICD/main/install.sh | sudo CLICD_VERSION=v1.1.6 sh
+```
+
+## 子用户能看到全部容器吗？
+
+不能。子用户只会看到管理员授权给他的容器。
+
+## API Key 和登录密码一样吗？
+
+不一样。API Key 在“API 集成”页面创建，用于程序化调用接口。登录密码用于 Web 面板登录。
+
+## 到达流量限制后会怎样？
+
+容器达到流量限制后会被自动关机，避免继续产生超额流量。管理员可以调整限制或重置流量。
+
+## IPv6 分配后为什么公网不通？
+
+IPv6 是否可达取决于宿主机和上游网络。需要确认宿主机拥有可路由 IPv6 地址段，并且路由、防火墙、邻居发现或代理配置正确。

+# 故障排查
+
+## 服务无法访问
+
+检查服务状态：
+
+```bash
+systemctl status clicd
+journalctl -u clicd -n 100 --no-pager
+```
+
+检查端口监听：
+
+```bash
+ss -lntp | grep 8999
+```
+
+如果使用反向代理，请同时检查代理日志和上游地址。
+
+## 镜像下载失败
+
+- 确认宿主机可以访问镜像源和 GitHub Release。
+- 检查磁盘空间。
+- 在任务队列里查看失败原因。
+- 如下载卡住，可尝试取消任务后重新下载。
+
+## 容器无法联网
+
+- 检查宿主机 NAT 和转发规则。
+- 检查容器 IP 是否分配成功。
+- 检查防火墙是否拦截转发流量。
+- IPv6 场景下确认上游已经把地址段路由到宿主机。
+
+## WebSSH 或 WebVNC 连接失败
+
+- 确认容器或虚拟机正在运行。
+- WebSSH 需要容器内 SSH 服务可用。
+- WebVNC 需要 KVM 控制台可访问。
+- 票据有效期很短，过期后重新创建即可。
+
+## API 返回未授权
+
+- 确认 API Key 没有被禁用。
+- 确认请求头使用 `X-API-Key` 或 `Authorization: Bearer`。
+- 确认密钥权限范围覆盖目标接口。
+- 不要把面板登录密码当作 API Key 使用。
