Question

我有一个由dotnet new web -o foo生成的.NET Core Web应用程序，以及以下（多阶段）Dockerfile：

FROM microsoft/dotnet:2.0-sdk AS builder

WORKDIR /build

COPY ./foo/foo.csproj .
RUN dotnet restore

COPY ./foo/*.cs ./
RUN dotnet publish --configuration Release --output ./app

FROM microsoft/dotnet:2.0-runtime

WORKDIR /app

COPY --from=builder /build/app/* ./

ENTRYPOINT ["dotnet", "./foo.dll"]

构建图像可以正常工作，但运行它不会：

PS> docker build . -t foo
# ...
Successfully built <hash>
Successfully tagged foo:latest
PS> docker run --rm foo
Error:
  An assembly specified in the application dependencies manifest (foo.deps.json) was not found:
    package: 'Microsoft.ApplicationInsights.AspNetCore', version: '2.1.1'
    path: 'lib/netstandard1.6/Microsoft.ApplicationInsights.AspNetCore.dll'
  This assembly was expected to be in the local runtime store as the application was published using the following target manifest files:
    aspnetcore-store-2.0.0-linux-x64.xml;aspnetcore-store-2.0.0-osx-x64.xml;aspnetcore-store-2.0.0-win7-x64.xml;aspnetcore-store-2.0.0-win7-x86.xml

似乎并非所有必需的资产都发布到输出目录;我还需要做些什么才能做到这一点？

一个解决方案存在同一问题的github issue和another：

ASP.NET Core运行时存储不包含在“仅运行时”映像中。您需要使用microsoft / aspnetcore：2.0.0，或者选择退出运行时存储修剪。

如果您想要更小的图像并且可以更改代码，则可以执行以下操作：

或（2）禁用发布时修剪，以便将依赖项程序集复制到已发布的输出中。

<PropertyGroup> <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest> </PropertyGroup>

由于缺少dll：s，使用.NET Core 2.0的Docker多阶段构建失败
