In Azure, I'm trying to import a custom hostname binding for my staging evironment using Terraform. Since my dev and test don't need staging, my staging slot has a count variable which is 1 for acc and prod.
Our anization is in the process of figuring out what rights to give to our pipeline to enable us to make hostname bindings ourselves. Until that time, the bindings are made by another team and imported.
This is part of our code:
variable "web_app_slot_count" {
type = number
description = "Number of slots (0 or 1)"
default = 0
# tfvars contains web_app_slot_count = 1
}
resource "azurerm_windows_web_app_slot" "staging" {
count = var.web_app_slot_count
...
}
resource "azurerm_app_service_custom_hostname_binding" "staging_abc_nl" {
count = var.web_app_slot_count
hostname = "${var.environment}-staging.rdc.nl"
app_service_name = "${module.appservice_abc.name}/staging"
resource_group_name = data.azurerm_resource_group.app.name
ssl_state = "SniEnabled"
thumbprint = data.azurerm_key_vault_certificate.ssl_certificate_staging[0].thumbprint
}
import {
id = "/subscriptions/12341234-1234-1234-1234-123412341234/resourceGroups/abc-acc-we-app-rg-001/providers/Microsoft.Web/sites/abc-acc-abc-we-app-001/hostNameBindings/acc-staging.abc.nl"
to = azurerm_app_service_custom_hostname_binding.staging_abc_nl[0]
}
Within our pipeline, this code produces an error:

Reset to default 1Firstly, make sure that the resource has been already existed before importing it into the current configuration. And modify the app service name under azurerm_app_service_custom_hostname_binding resource provider because the app service name might be throwing a conflict here and it is not to be in the format of ${module.appservice_abc.name}/staging instead refer it directly as ${module.appservice_abc.name} or azurerm_app_service.example.name.
Refer app service custom binding template from Terraform registry.
In order to make the count work, try to assign count value equals to 1 instead of default = 0. There might be an issue when this has been to set to 0 if there is no web app staging slot existed.
Modified terraform code:
resource "azurerm_key_vault_certificate" "example" {
name = "sample-cert"
key_vault_id = azurerm_key_vault.example.id
certificate {
contents = filebase64("xxxx.pfx")
}
}
resource "azurerm_windows_web_app_slot" "staging" {
count = 1
name = "stag-slot"
app_service_id = data.azurerm_windows_web_app.example.id
site_config {}
}
resource "azurerm_app_service_custom_hostname_binding" "example" {
count = var.web_app_slot_count
hostname = "stag-staging.rdc.nl"
app_service_name = data.azurerm_app_service.example.name
resource_group_name = data.azurerm_resource_group.app.name
ssl_state = "SniEnabled"
thumbprint = azurerm_key_vault_certificate.example[0].thumbprint
depends_on = [azurerm_windows_web_app_slot.example]
}
Output:
Note: You can try the terraform code with modified changes in your pipeline by setting up the pipeline configuration and clone the repos in the below way and it should work as expected.
