Questions[azure-resource-manager](server)

I'm starting to use Bicep to deploy Azure resources, and sometimes have to refer to other resources with the resourceId() function, but the arguments for this can be pretty long. In many languages, I could just put each parameter on its own line:

resourceId(
  'Microsoft.Network/virtualNetworks/subnets',
  'my-vnet',
  'my-subnet'
)

VSCode's Bicep linter marks this as an error, however, while it is fine with them all on a single line.

Is there a way to do this in Bicep? Microsoft's documentation on the actual syntax rules is either lacking or very hard to find!

I found a template for deploying AKS using Azure template.

The template link

When I try to run it, it is showing a form field to provide existing CIDR.

Is there anyway to keep a drop down so that we can opt for either to create a new vnet or use an exsting one, based on that it should hide out the remaining fields and create a vnet.

Please suggest how to achieve this.

I am creating an ARM template for the Azure Log Analytics workspace.it has some queries which use azure VM's VMUUID.Is there is any way to fetch the azure VM's VMUUID in ARM template or any other ways to fetch azure VMUUID?

I have an ARM template that deployes a scaleset to Azure and creates configuration files and runs a docker container via cloud-init.

All this works file and we have Azure DevOps running the template and redeploy on changes. BUT any changes to the cloud init file are not reflated until we manually reimage the servers. Is there any way to automatically (and preferably rolling) replace all the servers in the scaleset with the updated configuration?
