我一直在开发一个应用程序，它一直没有问题。当我尝试将它部署到 Ubuntu 主机上的 Docker 容器时。

图像构建部分进行得很好。但是在 docker 上运行该应用程序时，它会崩溃并出现以下异常。

我不知道这里可能出了什么问题，我知道该项目可以在其他机器上运行。我觉得这些知识可能有用: - postgres 服务器是具有另一个 Docker 容器的同一台 Ubuntu 主机。 - 这是 Dockerfile


    FROM microsoft/dotnet:2.2-sdk AS build
    WORKDIR /app

    COPY src/WayUpTo.sln ./src/WayUpTo.sln
    COPY src/WayUpTo/WayUpTo.csproj ./src/WayUpTo/WayUpTo.csproj
    COPY . ./
    RUN cd src; dotnet restore


    ARG build=Debug
    RUN cd src; dotnet publish --output /app/out --configuration ${build};

    # build runtime image
    FROM microsoft/dotnet:2.2-aspnetcore-runtime AS runtime
    WORKDIR /app
    COPY --from=build /app/out ./
    ENTRYPOINT ["dotnet", "WayUpTo.dll"]

感谢任何试图帮助我解决这个问题的人，我真的不知道哪里出了问题。

最佳答案

不知何故，是 NuGet 包管理器出了问题。降级到版本 2.2.0 后，它工作了。

关于postgresql - 应用程序无法在 docker 中运行，无法加载文件或程序集 'System.Runtime.CompilerServices.Unsafe，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57672852/
