我使用 csproj配置创建了一个web api项目（aspnetcore v2.1.0软件包）： autofac版本4.8.1

<TargetFramework>netcoreapp2.0</TargetFramework>
<Platform>AnyCPU</Platform>

我在 publishprofile ：

我还有两个文件可以在启动之前设置环境变量。 我有一个用于docker的env.list文件来设置应用程序特定的变量和一个带有export命令的等效bash脚本，用于在我的Mac上设置我的环境变量（以测试容器外的应用程序）。
在命令下运行会导致应用程序启动并可访问。
#in the publish folder, starting the app
dotnet myapp.dll
运行以下命令会导致在下面的命令后显示错误消息。
#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
myapp:latest

似乎Autofac缺少依赖性。我不想使用SDK图像，因为我没有在容器图像本身进行构建。我可以使用自包含选项进行部署，但我想知道这是否是正常行为，例如依赖System.Pipelines（autofac需要）不在运行时映像中。还是我错过了别的什么？
答案 0 :(得分：0)
如果您不使用预安装的SDK并且您不允许图像即时下载它所需的内容（构建），那么您必须发布一个独立的应用程序以确保包括所有依赖项在内的所有内容它是图像。
