Suggest a fix

It is described in the microsoft/aspnetcore-build registry as follows. It seems to require a migration.

Latest images for 2.1 and newer are now available on microsoft/dotnet. See this link for more details about migrating to 2.1.

Current Upgrade
microsoft/aspnetcore:1.0
microsoft/aspnetcore:1.1
microsoft/aspnetcore:2.0 		microsoft/dotnet:2.1-aspnetcore-runtime
microsoft/aspnetcore-build:1.0
microsoft/aspnetcore-build:1.1
microsoft/aspnetcore-build:2.0 		microsoft/dotnet:2.1-sdk

I will post a PR. 😃
