asp.net - MSBUILD : error MSB1011: Specify which project or solution file to use because this folder contains more than one project or solution file

Question

我是Docker的新手，正在尝试为ASP.NET Core应用程序创建Dockerfile。有人可以建议我需要哪些更改吗？

这是我的Dockerfile:

FROM microsoft/dotnet:2.1-sdk  
WORKDIR /app  
COPY Presentation/ECCP.Web/ *.csproj ./  
RUN dotnet restore  
COPY . ./  
RUN dotnet publish -c Release -o out  

FROM microsoft/aspnetcore:2.0  
WORKDIR /app  
COPY --from=build-env /app/out .  
ENTRYPOINT ["dotnet", "api.dll"]  

我面临以下错误:

MSBUILD : error MSB1011: Specify which project or solution file to use because this folder contains more than one project or solution file. The command '/bin/sh -c dotnet publish -c Release -o out' returned a non-zero code: 1

Answer 1

您的工作目录似乎包含.csproj和.sln文件。尝试在命令中指定.sln文件。
运行

dotnet publish your-solution-file.sln -c Release -o out

我在dotnet build上遇到了相同的错误消息，这可以解决它。

顺便说一句，由于.NET Core 2.0，dotnet restore命令是隐式运行的，因此您可以跳过它。
