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"]
但当执行命令docker build -t MyProject-web .时，它会给我一个错误：
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

这看起来更像是一个dotnet发布问题，而不是docker的实际问题。
如果搜索dotnet cli显示的MSB3073的实际错误，可以发现它通常与生成后事件有关。在许多情况下，生成后事件中引用的每个文件夹/程序集的路径都不正确。
如果我们仔细观察发布命令执行时的位置
WORKDIR /app/Presentation/MyProject.Web
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，或者使它们与执行发布命令的位置相对。您还可以为每个配置指定特定的后/前事件，以下是关于发布事件的答案
