如何构建docker映像文件并推送VST

如何在VSTS平台上推送代码时解决此错误。我正在使用Visual Studio 2017

我对Docker，Azure（VSTS）的概念是陌生的

---

根据DockerFile和错误消息，它无法复制aspnet core dotnet core/aspnet core dotnet core.csproj文件

---

您需要指定DockerFile的父文件夹路径作为生成上下文（取消选中使用默认生成上下文选项并指定生成上下文），然后它可以找到aspnet core dotnet core/aspnet core dotnet core.csproj文件看起来您的第一个COPY语句中有一个路径错误。您的源代码是否位于源代码管理中的子目录中，例如

src

？

FROM microsoft/aspnetcore:1.1 AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/aspnetcore-build:1.1 AS build
WORKDIR /src
COPY ["aspnet-core-dotnet-core/aspnet-core-dotnet-core.csproj", "aspnet-core-dotnet-core/"]
RUN dotnet restore "aspnet-core-dotnet-core/aspnet-core-dotnet-core.csproj"
COPY . .
WORKDIR "/src/aspnet-core-dotnet-core"
RUN dotnet build "aspnet-core-dotnet-core.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "aspnet-core-dotnet-core.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "aspnet-core-dotnet-core.dll"]
