Question

我创建了我的应用程序，它成功创建了docker容器。当我尝试运行它

docker run -it --name myapp myapp:latest

我收到以下错误：

The specified framework 'Microsoft.AspNetCore.All', version '2.1.2' was not found.
...
- The following versions are installed:
      2.1.1 at [/usr/share/dotnet/shared/Microsoft.AspNetCore.All]

登录到容器后，可以看到在/usr/share/dotnet/shared/Microsoft.AspNetCore.All文件夹中有一个名为2.1.2的子文件夹。

我不知道为什么说是安装了2.1.1而没有安装2.1.2吗？

以下是我的Dockerfile：

FROM microsoft/dotnet:2.1.400-sdk-stretch AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1.400-sdk-stretch AS build
WORKDIR /src
COPY source/application/MyApp/MyApp.csproj source/application/MyApp/
COPY source/application/MyApp.DependentProject/MyApp.DependentProject.csproj source/application/MyApp/
RUN dotnet restore source/application/MyApp/MyApp.csproj
COPY . .
WORKDIR /src/source/application/MyApp
RUN dotnet build MyApp.csproj -c Release -o /app

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

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

Answer 1

您可以尝试更改：

FROM microsoft/dotnet:2.1.400-sdk-stretch AS base

到

FROM microsoft/dotnet AS base

或

FROM microsoft/dotnet:2.1.2-sdk AS base

有关更多示例，请参见dotnet核心和docker上的docker docs和Microsoft docs

找不到指定的框架'Microsoft.AspNetCore.All'，版本'2.1.2'
