Add support for OS Disk resize in VMSS

[bpoland]

Hi there,

Wondering if it would be possible to add support for resizing an OS disk when deploying a Virtual Machine Scale Set.

The standalone Virtual machine supports an OsDiskSizeInMB property:

azure-sdk-for-go/arm/compute/models.go

Line 2267 in c1ff183

type VirtualMachineSize struct {

However, the Scale Set is missing that property:

azure-sdk-for-go/arm/compute/models.go

Line 1994 in c1ff183

type VirtualMachineScaleSetOSDisk struct {

I have been able to deploy a scale set with an ARM template specifying a disk size property like this (using API version 2017-03-30) so I know it's possible:

                    "storageProfile": {
                        "osDisk": {
                            "caching": "ReadWrite",
                            "createOption": "FromImage",
                            "diskSizeGB": "10",
                            "name": "[concat(variables('vmssName'), '-osp')]",
                            "osType": "Linux",
                            "image": {
                                "uri": "[variables('vmssImageUri')]"
                            }
                        }
                    },

Hope that makes sense -- thanks!

Howdy @bpoland, thanks for your submission! This sort of issue must be fixed upstream of us a bit, and I've added an issue to the Open API Specs repository which quotes this one. (You can see a link directly above this comment.)

I'm going to close this issue in favor of the specs repository one, but please feel free to continue commenting and following along there!

Okay, thanks for your help :)
