docker 的內置支持已生成 dockerfile 錯誤

Question

我的 VS 2019 生成了 Dockerfile 和下一個代碼：

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
WORKDIR /src
COPY ["src/Services/ProductCatalogApi/ProductCatalogApi.csproj", "src/Services/ProductCatalogApi/"]
RUN dotnet restore "src/Services/ProductCatalogApi/ProductCatalogApi.csproj"
COPY . .
WORKDIR "/src/Services/ProductCatalogApi"
RUN dotnet build "ProductCatalogApi.csproj" -c Release -o /app/build

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

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

當我使用命令docker build. 我收到了下一個：

Sending build context to Docker daemon  77.49MB
Step 1/16 : FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS base

COPY failed: stat /var/lib/docker/tmp/docker-builder040062339/src/Services/ProductCatalogApi/ProductCatalogApi.csproj: no such file or directory

我的.csproj 文件：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <RootNamespace>ShoesOnContainers.Services.ProductCatalogApi</RootNamespace>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
    <DockerfileContext>..\..\..</DockerfileContext>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.5" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.1.5" />

    <PackageReference Include="Swashbuckle.AspNetCore" Version="5.5.1" />
  </ItemGroup>


</Project>

在我的一整天中，我都在嘗試以其他方式構建我的形象，並且每次我收到錯誤。 幫助某人，請......

src/Services/ProductCatalogApi/ProductCatalogApi.csproj

從您運行它的文件夾中不存在。

如果 dockerfile 與 csproj 位於同一文件夾中，則應為

COPY ["ProductCatalogApi.csproj", "src/Services/ProductCatalogApi/"]

這有點棘手，如果您使用的是 docker-compose，則路徑必須是您嘗試運行的 docker-compose 文件的相對路徑
