[SOLVED] Apply multiple DSCs through Azure Resource Manager

Apply multiple DSCs through Azure Resource Manager

Is it possible to apply multiple DSC configurations to one vm through Azure Resource Manager?

Currently I am using something like this:

    {
      "apiVersion": "2015-06-15",
      "dependsOn": [
        "[concat('Microsoft.Compute/virtualMachines/', variables('vm_name'))]"
      ],
      "location": "[resourceGroup().location]",
      "name": "DSCSetup",
      "properties": {
        "publisher": "Microsoft.Powershell",
        "type": "DSC",
        "typeHandlerVersion": "2.20",
        "autoUpgradeMinorVersion": true,
        "settings": {
          "modulesUrl": "[concat('https://', variables('sa_name'), '.blob.core.windows.net/.../dsc.ps1.zip')]",
          "configurationFunction": "dsc.ps1\\Main",
          "properties": {
            "MachineName": "[variables('vm_name')]",
            "UserName": "[parameters('vm_user')]"
          }
        },
        "protectedSettings": {}
      },
      "type": "extensions"
    }

If not, can you merge multiple DSCs automatically?

Scenario is:

Have multiple DSCs
One DSC for IIS + ASP.Net
One DSC to create Site1
Another DSC to create Site2
In Dev deploy Site1 and Site2 to one machine
In Production deploy to seperate machines, maybe even in Availability Sets ...
(Be prepared to use seperate containers in the future)

Solution

DSC only allows for a single configuration at the moment, so if you deployed 2 DSC extensions to the same VM (I'm not sure it will actually work) the second config would overwrite the first.

You could probably stack DSC and CustomScript but since DSC can run script, I'm not sure why you'd ever need to do that...

What's your scenario?
