  Simple example: Use configs in a Windows serviceThis is a very simple example which shows how to use configs with a Microsoft
  IIS service running on Docker for Windows running Windows containers on
  Microsoft Windows 10. It is a naive example that stores the webpage in a config.This example assumes that you have PowerShell installed.Save the following into a new file index.html.
  
  <html lang="en">
   <head><title>Hello Docker</title></head>
   <body>
   <p>Hello Docker! You have deployed a HTML page.</p>
   </body>
  </html>If you have not already done so, initialize or join the swarm.
  
  docker swarm initSave the index.html file as a swarm config named homepage.
  
  docker config create homepage index.htmlCreate an IIS service and grant it access to the homepage config.
  
  docker service create
   --name my-iis
   --publish published=8000,target=8000
   --config src=homepage,target="\inetpub\wwwroot\index.html"
   microsoft/iis:nanoserverAccess the IIS service at http://localhost:8000/. It should serve
  the HTML content
  ```
