用于 Raspberry Pi 的 ASP.NET Core 应用程序在 VS2017 中使用 Docker

Question

我想将我的 Asp.Net Core 2.1 应用程序部署到我的 Raspberry Pi 3。

这是场景： 我在 VS 2017 中将应用程序开发为 docker 包装的应用程序

Raspberry Pi 正在运行安装了 docker 的 Raspbian。 该应用程序在开发机器上运行良好，但是当我将映像部署到 Raspberry 并尝试在那里运行时，我收到了错误：

standard_init_linux.go:190: exec user process caused "exec format error"

我认为这是因为我的图像架构错误（英特尔而不是 arm），但我不知道如何解决这个问题。请指教。

这是我的 docker 文件：

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY ["WebApplication4/WebApplication4.csproj", "WebApplication4/"]
RUN dotnet restore "WebApplication4/WebApplication4.csproj"
COPY . .
WORKDIR "/src/WebApplication4"
RUN dotnet build "WebApplication4.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "WebApplication4.csproj" -c Release -o /app 

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "WebApplication4.dll"]

你试过了吗？

# This Dockerfile uses nightly preview builds for .NET Core
# It will be updated to .NET Core 2.2 shortly
FROM microsoft/dotnet-nightly:2.1-sdk AS build
WORKDIR /app

# copy csproj and restore as distinct layers
COPY *.sln .
COPY aspnetapp/*.csproj ./aspnetapp/
RUN dotnet restore

# copy everything else and build app
COPY aspnetapp/. ./aspnetapp/
WORKDIR /app/aspnetapp
RUN dotnet publish -c Release -o out


FROM microsoft/dotnet-nightly:2.1-aspnetcore-runtime AS runtime
WORKDIR /app
COPY --from=build /app/aspnetapp/out ./
ENTRYPOINT ["dotnet", "aspnetapp.dll"]

这是官方dockerhub建议的。还有一些带有arm32标签的图片。
