"external_public_nic" - additional output to the bigip-module

[dfs5]

Can we have an additional output added to the bigip-module which would allow to assign the BIG-IP VE secondary IP as pool member to ALB.
I tried the workaround as mentioned here but it didn't work: #29

│ Error: Error: Network Interface (Subscription: "3ab97c04-ca68-41d4-8b83-2b9cf0723c23"
│ Resource Group Name: "dfsarag-rg-1b8b"

What needs to be added:

To be added under .terraform/modules/bigip/outputs.tf

output "external_public_nic" {
value = azurerm_network_interface.external_public_nic[0].id
}

What the modification would allow:

Then if ALB should front-end the BIG-IP the "external_public_nic" could be associate to the ALB Pool under bigip.tf

Associate the BIG-IP NIC to the ALB backend pool

resource "azurerm_network_interface_backend_address_pool_association" "f5vm01" {
network_interface_id = module.bigip.external_public_nic
ip_configuration_name = format("%s-secondary-ext-public-ip-0", element(split("-mgmt-0", element(split(".", module.bigip.mgmtPublicDNS), 0)), 0))
backend_address_pool_id = azurerm_lb_backend_address_pool.backend_pool.id
}
