c# - 找不到与命令“dotnet-/app/Build\ClearPluginAssemblies.dll” Docker 匹配的可执行文件
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"]
但是当执行命令时docker build -t MyProject-web .
它给了我一个错误:
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

解决方案
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特定的后/前事件,这是关于发布事件的答案
