"Using Nano Server for containers is their highest priority.
When it comes to containers, smaller is better.
Based on that feedback, we are making an important change to Nano Server. This next release will focus on making Nano Server the very best container image possible. From these changes, customers will now see the Nano Server images shrink in size by more than 50 percent, further decreasing startup times and improving container density. As part of this effort to focus on containers, we will be removing the functionality for infrastructure-related roles. Instead of using Nano Server for these scenarios, we recommend deploying the Server Core installation option, which includes all the roles and features you would need. These changes to Nano Server, combined with the new application innovations in .NET Core 2.0 which enables customers to use more of their code in more places, make Nano Server the best option for new container-based development."
