Where I can find default template of Dockerfile created by VisualStudio for "ASP.NET Core Web App (Razor Pages)" project template?

Hello everybody!
Can anybody explain me, where I can find source of Dockerfile created for "ASP.NET Core Web App (Razor Pages)" project template?
If I correctly understand, project template is here, but I can not find Dockerfile in this folder

You won’t find the Dockerfile in that project template folder—it’s an item template embedded in Visual Studio/SDK.
