Deploy private link on azure cosmosdb

Hello

Deploying private link on CosmosDB with a failover

When deploying private link I need to provide an A record, one usually use this kind of code:

resource “azurerm_private_dns_a_record” “a_record” {
records = [azurerm_private_endpoint.pe.private_service_connection[0].private_ip_address]


}

I deploy on westeurope with a failover on northeurope.
Cosmosdb needs two more records, one for each region where cosmosdb is deployed:

https://learn.microsoft.com/en-us/azure/cosmos-db/how-to-configure-private-endpoints?tabs=arm-bicep

So my issue is to fetch the private failover IP.

azurerm_private_endpoint.pe.custom_dns_configs display the values I need, so I tested:

resource “azurerm_private_dns_a_record” “a_record” {
for_each = azurerm_private_endpoint.pe.custom_dns_configs
name = each.value.fqdn
records = each.value.ip_addresses


}

But it does not work because is evaluate on apply and not available at plan:

The “for_each” map includes keys derived from resource attributes that

│ cannot be determined until apply, and so Terraform cannot determine the

│ full set of keys that will identify the instances of this resource.

│ When working with unknown values in for_each, it’s better to define the map

│ keys statically in your configuration and place apply-time results only in

│ the map values.

│ Alternatively, you could use the -target planning option to first apply

│ only the resources that the for_each value depends on, and then apply a

│ second time to fully converge

So is there any way to solve this issue?

Thank you
