将.Net Core API应用程序发布到Docker

Question

我已经创建了一个新的.Net Core API应用程序，并且希望将其托管在Docker容器中。

我已经下载了Docker Toolbox，在我的应用程序中创建了一个Docker文件，如下所示：

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-nanoserver-sac2016 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-nanoserver-sac2016 AS build
WORKDIR /src
COPY ["BuySellApi/BuySellApi.csproj", "BuySellApi/"]
COPY ["BuySellApi.Data/BuySellApi.Data.csproj", "BuySellApi.Data/"]
COPY ["../BuySellApi.Core/BuySellApi.Core.csproj", "../BuySellApi.Core/"]
RUN dotnet restore "BuySellApi/BuySellApi.csproj"
COPY . .
WORKDIR "/src/BuySellApi"
RUN dotnet build "BuySellApi.csproj" -c Release -o /app

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

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

此后，我尝试使用以下命令使用docker构建应用程序：

E:\Apps\trunk\BuySell\BuySellApi>docker build -t dockerapi .

但是出现如下错误：

是因为有代理吗？因为我正在办公室网络中尝试。如果是，如何配置代理，以便我可以顺利构建它？
