Add support to create VM from image gallery

[hriaz]

REF: #4

As part of level 3 solution deployment, we have the ability to create a shared image gallery. I am unable to find any documentation or reference on how to deploy a virtual machine from a shared image gallery. We need to support deploying a virtual machine from a shared image gallery published with the following configurations:

• Shared Image gallery in the same subscription as the virtual machine
• Shared Image gallery in a different subscription but same tenant as the virtual machine
• Shared Image gallery in a different tenant and subscription

hi @hriaz have you looked there?

terraform-azurerm-caf/modules/compute/virtual_machine/vm_linux.tf

Line 101 in 32593cd

source_image_id = try(each.value.custom_image_id, var.custom_image_ids[each.value.lz_key][each.value.custom_image_key].id, null)

So I look at this code, when you specify custom_image_id you should be able to create it.

As I'm looking at the shared image gallery module, we dont have the right output there: custom_image_ids, so it will require a bit of updating.

Hi @arnaudlh When trying to use custom_image_id and source_image_reference is removed, it throws an error of expected value of "Error: "source_image_reference.0.version": required field is not set". When prepending custom_image_id and still leaving source_image_reference value, the machine is not deployed using the approved image in the shared image gallary.

OK will have a deeper look @hriaz

@arnaudlh Thanks for looking into this. I can confirm this worked for windows and Linux. This works in the latest modules after some tweaking.

well custom_image_id doesnt work with vmss. its in same subscription image gallery, same region, different resource group but connected through peering. please can you check this #1334
