为 dotnet 6 应用程序创建 Docker 图像 - 类型“”已经定义了一个名为“”的具有相同参数类型的成员

Question

我正在尝试为 .net 6 web api 应用程序创建 docker 图像，每当我运行命令时：
~ sudo docker build -t aspnetapp .
它向我显示以下错误：

/src/AmplifyAPI.Application/Controllers/Product/ProductController.cs(22,38): error CS0111: Type 'ProductController' already defines a member called 'SaveProduct' with the same parameter types [/src/AmplifyAPI.Application/AmplifyAPI.Application.csproj]

每个控制器的每个方法都会显示该错误。这是我的 docker 文件：

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY . .
RUN dotnet restore "AmplifyAPI.Application/AmplifyAPI.Application.csproj" --disable-parallel
WORKDIR "/src/AmplifyAPI.Application"
COPY . .
RUN dotnet build "AmplifyAPI.Application.csproj" -c Release -o /app

FROM build AS publish
WORKDIR "/src/AmplifyAPI.Application"
RUN dotnet publish "AmplifyAPI.Application.csproj" -c Release -o /app

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

应用程序结构是：

--src
-----Dockerfile
-----AmplifyAPI.Data
-----AmplifyAPI.Domain
-----AmplifyAPI.Application
---------Controllers

--tests
-----AmplifyAPI.UnitTests
-----AmplifyAPI.IntegrationTests

应用程序在本地构建得很好。我正在使用 Linux 作为操作系统。

您将源代码复制到容器中的不同位置两次。您还构建并发布到 /app，这可能会导致问题。

.NET 项目的普通 Dockerfile 首先复制 .csproj 文件，然后执行 restore 然后复制其余代码并构建，就像这样

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY AmplifyAPI.Application/AmplifyAPI.Application.csproj ./AmplifyAPI.Application/
COPY AmplifyAPI.Data/AmplifyAPI.Data.csproj ./AmplifyAPI.Data/
COPY AmplifyAPI.Domain/AmplifyAPI.Domain.csproj ./AmplifyAPI.Domain/
RUN dotnet restore "AmplifyAPI.Application/AmplifyAPI.Application.csproj" --disable-parallel
COPY . .
RUN dotnet build "AmplifyAPI.Application/AmplifyAPI.Application.csproj" -c Release

FROM build AS publish
WORKDIR "/src"
RUN dotnet publish "AmplifyAPI.Application/AmplifyAPI.Application.csproj" -c Release -o /app

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