在过去的一天里我一直在寻找答案，但到目前为止还没有找到答案。
到目前为止，我的程序只是一个新的默认dotnet new reactredux命令。
我制作了一个 Dockerfile，当我进行构建并在我的计算机上运行时，它可以正常工作。
FROM microsoft/aspnetcore-build AS build
WORKDIR /app
COPY . .
RUN dotnet restore
RUN dotnet publish --output /output --configuration Release
FROM microsoft/aspnetcore-build
WORKDIR /app
COPY --from=build /output .
ENTRYPOINT [ "dotnet", "Docker.dll" ]
但我无法让它在我的数字海洋码头工人滴上工作。
据我了解，FROM获取其他 docker 映像，并且这个 Dockerfile 是一个多阶段 Dockerfile，其中一个FROM是帮助在本地构建和使用，另一个是帮助运行时。
我所要做的就是设置默认的dotnet reactredux Web应用程序并将其dockerise。我看得太偏了/错过了什么？
这是 docker droplet 上的错误，或者如果我在第二个FROM上取下 -build .
