title: Docker's image and host are incompatible
body: <p>I have created a docker image of an asp.net core mvc 3 (preview) on my personal computer which runs Windows 10.0.17134.  My docker files the Windows Server Nano image </p>
  
  <blockquote>
    <p>FROM microsoft/dotnet:3.0-aspnetcore-runtime-nanoserver-1809 AS base
    ...</p>
  </blockquote>
  
  <p>This image is published to a repository on AWS ECS, and I have setup tasks and services and clusters all OK.</p>
  
  <p>However my container fails to start with the below error:</p>
  
  <blockquote>
    <p>Status reason CannotPullContainerError: a Windows version
    10.0.17134-based image is incompatible with a 10.0.14393 host</p>
  </blockquote>
  
  <p>I am sure I am running Widows server on the host so why is it complaining that my host is Windows 10.0.14393 ?? That is the version of Windows on my personal laptop!  </p>
