+本文档提供了使用Docker环境来构建和运行Humanus.cpp项目的指南。 + +## 环境配置 + +Docker环境采用多阶段构建方式，包含以下组件： + +- Ubuntu 20.04 作为基础操作系统 +- C++ 编译工具链 (GCC, G++, CMake) +- OpenSSL 开发库支持 +- Python3 开发环境 +- Node.js 18.x 和 npm 支持 +- 预安装的npm包: + - @modelcontextprotocol/server-puppeteer + - @modelcontextprotocol/server-filesystem + - @kevinwatt/shell-mcp + - @modelcontextprotocol/server-everything + +### 多阶段构建的优势 + +我们的Dockerfile采用了多阶段构建方法，具有以下优点： +1. **优化镜像大小**：最终镜像只包含运行时必要的组件 +2. **简化依赖管理**：所有依赖都在构建阶段解决，运行阶段不需要网络连接 +3. **提高构建成功率**：通过分离构建和运行环境，减少构建失败的风险 +4. **加快开发速度**：预构建的工具链减少每次容器启动的准备时间 + +## 使用方法 + +### 构建并启动开发环境 + +使用提供的脚本最为简便： + +```bash +# 使用便捷脚本启动开发环境 +./.devops/scripts/start-dev.sh +``` + +此脚本会: +1. 构建Docker镜像（使用多阶段构建） +2. 启动容器 +3. 询问是否进入容器 + +也可以手动执行这些步骤： + +```bash +# 进入项目根目录 +cd /path/to/humanus.cpp + +# 构建并启动容器 +docker-compose -f .devops/docker-compose.yml build +docker-compose -f .devops/docker-compose.yml up -d + +# 进入容器的交互式终端 +docker-compose -f .devops/docker-compose.yml exec humanus bash +``` + +### 在容器内编译项目 + +使用提供的脚本： + +```bash +# 使用便捷脚本构建项目 +./.devops/scripts/build-project.sh +``` + +或者手动执行： + +```bash +# 进入容器 +docker-compose -f .devops/docker-compose.yml exec humanus bash + +# 在容器内执行以下命令 +cd /app/build +cmake .. +make -j$(nproc) +``` + +编译完成后，二进制文件将位于 `/app/build/bin/` 目录下。 + +### 运行项目 + +可以通过以下方式运行编译后的项目： + +```bash +# 从容器外运行 +docker-compose -f .devops/docker-compose.yml exec humanus /app/build/bin/humanus_cli + +# 或者在容器内运行 +# 先进入容器 +docker-compose -f .devops/docker-compose.yml exec humanus bash +# 然后在容器内运行 +/app/build/bin/humanus_cli +``` + +## 开发工作流 + +1. 在宿主机上修改代码 +2. 代码会通过挂载卷自动同步到容器内 +3. 在容器内重新编译项目 +4. 在容器内测试运行 + +## 注意事项 + +- 项目的构建文件存储在Docker卷`humanus_build`中，不会影响宿主机的构建目录 +- Node.js和npm已在镜像中预先安装，无需额外设置 +- 默认暴露了8818端口，如果需要其他端口，请修改`docker-compose.yml`文件 + +## 网络问题解决方案 + +如果您在构建过程中仍然遇到网络连接问题，可以尝试以下解决方案： + +### 解决EOF错误 + +如果遇到类似以下的EOF错误： + +``` +failed to solve: ubuntu:20.04: failed to resolve source metadata for docker.io/library/ubuntu:20.04: failed to authorize: failed to fetch anonymous token: Get "https://auth.docker.io/token?scope=repository%3Alibrary%2Fubuntu%3Apull&service=registry.docker.io": EOF +``` + +这通常是网络连接不稳定或Docker的DNS解析问题导致的。解决方法： + +1. **配置Docker镜像加速**： + +在Docker Desktop设置中添加以下配置： + +```json +{ + "registry-mirrors": [ + "https://registry.docker-cn.com", + "https://docker.mirrors.ustc.edu.cn", + "https://hub-mirror.c.163.com" + ] +} +``` + +2. **使用构建参数和标志**： + +```bash +# 使用选项3在start-dev.sh脚本中 +# 或手动执行 +docker-compose -f .devops/docker-compose.yml build --build-arg BUILDKIT_INLINE_CACHE=1 --network=host +``` + +3. **尝试拉取基础镜像**： + +有时先单独拉取基础镜像可以解决问题： + +```bash +docker pull ubuntu:20.04 +``` + +### 设置代理 + +在终端中设置HTTP代理后再运行构建命令： + +```bash +# 设置HTTP代理环境变量 +export HTTP_PROXY=http://your-proxy-server:port +export HTTPS_PROXY=http://your-proxy-server:port +export NO_PROXY=localhost,127.0.0.1 + +# 然后运行构建 +docker-compose -f .devops/docker-compose.yml build +``` + +### 使用Docker镜像加速器 + +在Docker Desktop设置中添加镜像加速器： + +1. 打开Docker Desktop +2. 进入Settings -> Docker Engine +3. 添加以下配置： +```json +{ + "registry-mirrors": [ + "https://registry.docker-cn.com", + "https://docker.mirrors.ustc.edu.cn", + "https://hub-mirror.c.163.com" + ] +} +``` +4. 点击"Apply & Restart" + +## 问题排查 + +如果遇到问题，请尝试以下步骤： + +1. 检查容器日志：`docker-compose -f .devops/docker-compose.yml logs humanus` +2. 重新构建镜像：`docker-compose -f .devops/docker-compose.yml build --no-cache` +3. 重新创建容器：`docker-compose -f .devops/docker-compose.yml up -d --force-recreate` +4. 网络问题：确认Docker可以正常访问互联网，或设置适当的代理 +5. 磁盘空间：确保有足够的磁盘空间用于构建和运行容器 +6. 如果看到"Read-only file system"错误，不要尝试修改容器内的只读文件，而是通过环境变量配置 \ No newline at end of file diff --git a/.devops/Dockerfile b/.devops/Dockerfile new file mode 100644 index 0000000..3990622 --- /dev/null +++
