node.js - Visual Studio for Mac上的Docker构建错误-当前上下文中没有构建阶段

Question

使用Docker和Visual Studio在Mac上使用Angular和Node.js构建ASP.NET CORE应用时遇到问题。

这是当前的错误:

> /Applications/Visual
> Studio.app/Contents/Resources/lib/monodevelop/AddIns/docker/MonoDevelop.Docker/MSbuild/Sdks/Microsoft.Docker.Sdk/build/Microsoft.VisualStudio.Docker.Compose.targets(5,5):
> Error: Building fjord.karve.experiment.server No build stage in current
> context.
> 
> For more troubleshooting information, go to
> http://aka.ms/DockerToolsTroubleshooting (docker-compose)

这是我当前的Docker File Attempt:

WORKDIR /app
EXPOSE 80

FROM microsoft/aspnetcore-build:2.0 AS build
WORKDIR /src
COPY Fjord.sln ./
COPY fjord.karve.experiment.server/fjord.karve.experiment.server/Fjord.Karve.Experiment.Server.csproj fjord.karve.experiment.server/fjord.karve.experiment.server/

RUN apt-get update && \
    apt-get install -y wget && \
    apt-get install -y gnupg2 && \
    wget -qO- https://deb.nodesource.com/setup_6.x | bash - && \
    apt-get install -y build-essential nodejs 

    dotnet build -c Release -o /app

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

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "Fjord.Karve.experiment.Server.dll"]

我可能应该提到，我尝试使用以下命令提前几分钟回到绘图板。这可能导致了某些意外问题。

docker images
docker rmi $(docker images -a -q)

documentation表示，第一个FROM只能在ARG指令之后。
