I'm trying to build a custom ARM template that deploys a new resource group (web,sql,redis,storage) that also creates a custom CNAME record in our dnsZone hosted in a different/existing resGroup. Finally, I'd like to add a certificate binding (wildcard) from our KeyVault also stored in the other resGroup.
It seems there is support for adding a zone in the new resGroup, but can't find example of leveraging existing zone and just adding a CNAME record that points to my new web app.
It also seems there are examples of creating Key Vaults, but not binding a site up to an existing cert in an existing vault in a different resGroup.
This is a very common multi-tenant kind of scenario, sure seems it should be possible in our template, without having to rely on PowerShell or Azure CLI.
