Я создал проект web api (пакеты aspnetcore v2.1.0) с этой конфигурацией csproj : и autofac версии 4.8.1 

<PropertyGroup>
  <TargetFramework>netcoreapp2.0</TargetFramework>
  <Platform>AnyCPU</Platform>
  <RuntimeIdentifiers>linux-x64;win-x64</RuntimeIdentifiers>
  <GenerateDocumentationFile>true</GenerateDocumentationFile>
</PropertyGroup>

Я создаю выходные данные публикации с этой конфигурацией в моем publishprofile : 

<Project ToolsVersion="4.0" 
 xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <WebPublishMethod>FileSystem</WebPublishMethod>

    <SiteUrlToLaunchAfterPublish />
    <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish>
    <ExcludeApp_Data>False</ExcludeApp_Data>

    <RuntimeIdentifier>linux-x64</RuntimeIdentifier>
    <SelfContained>False</SelfContained>
    <_IsPortable>false</_IsPortable>
  </PropertyGroup>
 </Project>

и этом Dockerfile : 

FROM microsoft/dotnet:2.1-aspnetcore-runtime
WORKDIR /app

У меня также есть два файла для установки переменных среды перед запуском.У меня есть файл env.list для докера, чтобы установить переменные, специфичные для приложения, и эквивалентный скрипт bash с командами экспорта, чтобы установить переменные среды на моем Mac (для тестирования приложения вне контейнера).

Поведение вне контейнера

Запуск команды ниже приводит к запуску и доступу приложения. 

#in the publish folder, starting the app
dotnet myapp.dll

Поведение внутри контейнера

Результаты выполнения команды нижев сообщениях об ошибках, показанных после команды ниже. 

#in the root directory containing the publish folder, the dockerfile 
and the env.list file.
docker build --no-cache -t myapp .
docker run -p 80:80--env-file ./env.list --name myappinstance

Похоже, что в Autofac отсутствует зависимость.Я не хочу использовать образ SDK, так как я не делаю сборку в самом образе контейнера.Я мог бы использовать самодостаточную опцию для развертывания, но мне было интересно, является ли это нормальным поведением, которое, например, в зависимости от образа System.Pipelines (которая нужна автофаку) отсутствует в образе времени выполнения.Или я что-то упускаю?

Если вы не используете предустановленный SDK и не позволяете образу загружать то, что ему нужно, на лету (сборка), то вам нужно опубликовать автономное приложение, чтобы гарантировать, что все, включая все зависимости, создаетэто к изображению.
