title: aks-engine custom image for node
body: <p>On the aks-engine github there is an example for a custom image for a node as follows: </p>
  
  <pre><code>"agentPoolProfiles": [
    {
      "name": "agentpool1",
      "count": 3,
      "imageReference": {
        "name": "stretch",
        "resourceGroup": "debian"
      },
      "vmSize": "Standard_D2_v2",
      "availabilityProfile": "AvailabilitySet"
    }
  ]
  </code></pre>
  
  <p>When I use this in my aks-engine generated ARM it can't find the resource group because I have not created it and not uploaded an a debian VHD as an Image in Azure. </p>
  
  <p>Is there a way of using pre-made images on Azure instead of having to upload our own?</p>
