FaceRecognitionDotNet人脸识别项目发布到linux服务器docker容器详细教程

本人服务器为linux Ubuntu
首先新增Dockerfile，我使用的Dockerfile文件如下：

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base

WORKDIR /app
EXPOSE 8000
EXPOSE 9000

WORKDIR /app
COPY .   /app
ENTRYPOINT ["dotnet", "FaceApi.dll"]

项目在docker上可以正常发布，但是FaceRecognition.Create(@“./models”)这句代码一直报错，错误如下

 Unable to load shared library 'DlibDotNetNativeDnn' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libDlibDotNetNativeDnn: cannot open shared object file: No such file or directory

经过百度搜索国内几乎找不到相关文档，果断谷歌，之后经过谷歌搜索发现在docker build的时候需要安装libopenblas-dev，因为FaceRecognitionDotNet依赖于它，而且必须安装在docker容器的环境中，如果只装在本机上那么在docker中还是会报错，然后修改Dockerfile如下

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
RUN apt-get update && apt-get install -y \
    libopenblas-dev \
    liblapack-dev \
    libx11-6 \
    libgdiplus \
    && apt-get clean && rm -rf /var/lib/apt/lists/*

WORKDIR /app
EXPOSE 8000
EXPOSE 9000

WORKDIR /app
COPY .   /app
ENTRYPOINT ["dotnet", "FaceApi.dll"]

新增如下代码是用于安装相关依赖的

RUN apt-get update && apt-get install -y \
    libopenblas-dev \
    liblapack-dev \
    libx11-6 \
    libgdiplus \
    && apt-get clean && rm -rf /var/lib/apt/lists/*

重新build又报错：

Some index files failed to download. They have been ignored, or old ones use

就是下载东西超时之类的，又一顿谷歌，找到解决办法：
在/etc/docker目录下建立新文件daemon.json,并输入如下内容：

{
   "dns":["8.8.8.8", "114.114.114.114"]
}

然后重启docker sudo systemctl restart docker
重新build发现下载依赖包特别慢，解决办法是更换为华为国内镜像源：

RUN  sed -i s@/deb.debian.org/@/mirrors.huaweicloud.com/@g /etc/apt/sources.list
RUN  apt-get clean
RUN  apt-get update

重新build终于成功！
完整的Dockerfile文件如下:

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base

RUN  sed -i s@/deb.debian.org/@/mirrors.huaweicloud.com/@g /etc/apt/sources.list
RUN  apt-get clean
RUN  apt-get update
RUN apt-get update && apt-get install -y \
    libopenblas-dev \
    liblapack-dev \
    libx11-6 \
	libgdiplus \
    && apt-get clean && rm -rf /var/lib/apt/lists/*

WORKDIR /app
EXPOSE 8000
EXPOSE 9000

WORKDIR /app
COPY .   /app
ENTRYPOINT ["dotnet", "FaceApi.dll"]

另外提一下，如果发布到windows server iis服务器上报错找不到模块，那么需要安装 Microsoft Visual C++
