[rjsigma]

Is there an existing issue for this?

• I have searched the existing issues

Description

Web app routing is a preview feature that seems to be a good option for managing ingress. The support for web app routing is added to underlying terraform resources version 3.30, around November 2022.

New or Affected Resource(s)/Data Source(s)

azurerm_kubernetes_cluster

Potential Terraform Configuration

given the `web_app_routing` block only support a single attribute `dns_zone_id`, we could elevate the value as a top level variable.

variable "web_app_rounting_dns_zone_id" {
  type = string
  default = ""
  ...
}
...
resource "azurerm_kubenetes_cluster" {
  ...
  dynamic "web_app_routing" {
    for_each = var.web_app_routing_dns_zone_id != "" ? ["dns_zone_id"] : []
    content {
      dns_zone_id = var.web_app_routing_dns_zone_id
    }
  }
  ...
}
