docker - 未找到 asp.net 核心 docker linux 程序集

Question

在 linux 上将 asp.net core 2.2 应用程序部署到 docker 时，运行 dotnet someprogram.dll 时，它提示找不到依赖项 dll。但显然 dll 与 someprogram.dll 位于同一文件夹中，该消息专门提示缺少“lib/dotnetstandard2.0/someassembly.dll”处的程序集。这是为什么？ dll应该在哪里？

这是Dockerfile :

FROM microsoft/dotnet:2.2-sdk AS build 
WORKDIR /app 
COPY . . 
WORKDIR /app/WebService 
RUN dotnet build -c Release -o /app/out 

FROM build AS publish 
RUN dotnet publish -c Release -o /app/out 

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

Answer 1

事实证明，这条线造成了麻烦。

FROM build AS publish

注释掉后，该应用程序开始工作。

这是 Dockerfile

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

COPY . . 

WORKDIR /app/WebService 
RUN dotnet publish -c Release -o /app/out 

FROM microsoft/dotnet:2.2-aspnetcore-runtime 
WORKDIR /app 
COPY --from=build /app/out . 

ENTRYPOINT ["dotnet", "WebService.dll"]
