【问题描述】：

我正在尝试使用 docker 映像运行我的 ASP.NET Core 2.1 应用程序。为此，我有包含以下内容的 docker 文件：

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /app

# copy csproj and restore as distinct layers
COPY . .
RUN dotnet restore

# copy everything else and build app
COPY Presentation/MyProject.Web/. ./Presentation/MyProject.Web/
WORKDIR /app/Presentation/MyProject.Web
RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/dotnet:aspnetcore-runtime
WORKDIR /app
COPY --from=build /app/Presentation/MyProject.Web/out .
ENTRYPOINT ["dotnet", "MyProject.Web.dll"]

但是当执行命令docker build -t MyProject-web .它给我一个错误：

The command '/bin/sh -c dotnet publish -c Release -o out' returned a non-zero code: 1

 MyProject.Web -> /app/Presentation/MyProject.Web/bin/Release/netcoreapp2.1/MyProject.Web.dll

编辑 1： 这是我的项目结构：

    ClearPluginAssemblies
Libraries
    MyProject.Core
    MyProject.Data
    MyProject.Services
Plugins
    MyProject.Plugin.Discount
    MyProject.Plugin.Payment

【问题讨论】：

你的项目文件夹结构是什么？你跑了哪条路docker build？你在docker build 命令中错过了. 吗？与我们分享一个演示项目以重现您的问题。
@TaoZhou：对不起，我错过了问题中已更新的.。此外，添加了项目结构。进一步注意，我已将此解决方案提供给另一个解决方案，他能够构建映像并运行容器，但是同样我面临一个问题，这很奇怪
你能把MyProject.Web的项目文件贴出来吗？而且，.. 您将包括所有工件的解决方案复制到您的 docker 映像中。（并且 MyProject.Web 被复制了两次）。您可以先尝试清理解决方案，以确保现有工件没有问题。如果这没有帮助，我会删除从您的发布行开始的所有内容并构建并运行您的图像。然后进入您正在运行的容器，检查复制的内容并手动运行发布命令 - 或测试一些其他命令。
@ChristophLütjen：在问题中添加了 MyProject.Web
@deeptowncitizen，是的，我在 windows 系统上使用 Linux 容器，我切换到 windows 容器并开始工作

【解决方案1】：

这看起来更像是 dotnet 发布问题，而不是 docker 的实际问题。

如果您搜索 dotnet cli 显示的实际错误 MSB3073，您会发现它通常与构建后事件有关。在许多情况下，构建后事件中引用的每个文件夹/程序集的路径都不正确。

如果我们仔细看看我们在执行发布命令时所处的位置

WORKDIR /app/Presentation/MyProject.Web

然后例如查看错误消息中的PluginPath

..PluginPath=/app/Presentation/MyProject.Web/Plugins/DiscountRules.CustomerRoles/;..

然后您可以看到该路径不是从执行命令的位置内联的。

一种解决方案是添加绝对路径或使它们相对于执行发布命令的位置。您还可以为每个配置指定一个特定的 post/pre-events，here's 一个关于发布事件的答案
