如何在 IoT Edge 运行时项目中将 appsetting.json 文件的路径设置为 DockerFile

Question

我在 windows 容器上创建了一个 IOT 边缘运行时自定义模块项目。虽然运行我面临的解决方案是 System cannot Find the file specified。我正在传递 appsetting.json 文件中的值，而运行未指定模块路径。

在构建映像时，我可以通过某种方式将 appsetting.json 文件复制到容器中吗？

这是我正在使用的 Dockerfile：

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1809 AS build-env
WORKDIR /app

COPY *.csproj ./
COPY appsettings.json ./
RUN dotnet restore

COPY . ./
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/core/runtime:3.1-nanoserver-1809
WORKDIR /app
COPY --from=build-env /app/out ./
ENTRYPOINT ["dotnet", "project.dll"]

这是 cs.proj 文件

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>
  
  <PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Debug|netcoreapp3.1|AnyCPU'">
    <TreatWarningsAsErrors>True</TreatWarningsAsErrors>
    <TreatSpecificWarningsAsErrors />
  </PropertyGroup>

  <ItemGroup>
    <ProjectCapability Include="AzureIoTEdgeModule" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.Devices.Client" Version="1.*" />
    <PackageReference Include="System.Runtime.Loader" Version="4.3.0" />
  </ItemGroup>

  <ItemGroup>
    <Reference Include="SasLib">
      <HintPath>lib\SasLib.dll</HintPath>
    </Reference>
  </ItemGroup>

  <ItemGroup>
    <Compile Update="Resource\Resource.Designer.cs">
      <DesignTime>True</DesignTime>
      <AutoGen>True</AutoGen>
      <DependentUpon>Resource.resx</DependentUpon>
    </Compile>
  </ItemGroup>

  <ItemGroup>
    <EmbeddedResource Update="Resource\Resource.resx">
      <Generator>ResXFileCodeGenerator</Generator>
      <LastGenOutput>Resource.Designer.cs</LastGenOutput>
    </EmbeddedResource>
  </ItemGroup>
</Project>

Answer 1

尝试在 Windows 容器中指定要复制 appsettings.json 文件的文件夹

COPY appsettings.json c:/temp/

Answer 2

好像appsettings.json没有复制到输出目录。尝试将其添加到 csproj 文件中

 <ItemGroup>
    <None Update="appsettings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>
