asp.net - What is the difference between IIS &Aspnet Containers?

Question

I want to containerize my ASP.Net Framework 4.6 application and I see the following base Images

1. aspnet:4.8-20191210-windowsservercore-ltsc201
2. iis:windowsservercore-ltsc2019

What is the difference between those? which is the one to be used to containerize the ASP.Net Framework 4.6 application

Answer 1

As you can see in these two docker files, the main difference is the availaibility of dotnet framework. aspnet image has the framework installed while iis one doesn't. You should use aspnet base container so that you wouldn't have to install the framework in the container yourself.
