title: Cannot find latest dotnet core images on docker (2.2.7)
body: <p>I am using this docker image now:</p>
  
  <p><code>microsoft/dotnet:2.2.2-aspnetcore-runtime-alpine</code></p>
  
  <p>I want to upgrade to 2.2.7 but can't manage to find correct tag on docker:</p>
  
  <p>This url <code>https://registry.hub.docker.com/v1/repositories/microsoft/dotnet/tags</code> seems to only have 2.2.2 as the latest version.</p>
  
  <p>It seems that Microsoft has moved to their own docker repository (mcr.microsoft.com/dotnet/core/runtime:2.2) while maintaining documentation on docker hub? I am really confused with what is going on in there.</p>
  
  <p>So I really want to find a corresponding image to my original but version 2.2.7 for both aspnet or ordinary runtime (without aspnet)</p>
