Terraform can't create free web app on azure - azure

Question

Trying to setup my first web app using terraform on Azure using there freetier.
The Resource group, and app service plan were able to be created but the app creation gives an error that says:
creating Linux Web App: (Site Name "testazurermjay" / Resource Group "test-resources"): web.AppsClient#C. Status=<nil> <nil>
Here is the terraform main.tf file:
provider "azurerm" {
features {}
}
resource "azurerm_resource_group" "test" {
name = "test-resources"
location = "Switzerland North"
}
resource "azurerm_service_plan" "test" {
name = "test"
resource_group_name = azurerm_resource_group.test.name
location = "UK South" #azurerm_resource_group.test.location
os_type = "Linux"
sku_name = "F1"
}
resource "azurerm_linux_web_app" "test" {
name = "testazurermjay"
resource_group_name = azurerm_resource_group.test.name
location = azurerm_service_plan.test.location
service_plan_id = azurerm_service_plan.test.id
site_config {}
}
At first I thought the name was the issue for the azurerm_linux_web_app so I changed it from test to testazurermjay however that was not able to work.

Answer 1

I was able to get it to work BUT I had to use a depreciated resource called azurerm_app_service instead of azurerm_linux_web_app. I ALSO had to make sure that my resource-group and app service plan were in the same location. When I originally tried to set both the resource group and the app plan to Switzerland North it would give me an error when creating the app service plan (That is why you see me change the plan to UK South in the Original question). HOWEVER - after I set BOTH resource group and app service plan to UK South they were able to be created in the same location. Then I used azurerm_app_service to create a free tier service using the use_32_bit_worker_process = true variable in the site_config object.
Here is the full terraform file now:
provider "azurerm" {
features {}
}
resource "azurerm_resource_group" "test" {
name = "test-resources"
location = "UK South"
}
resource "azurerm_service_plan" "test" {
name = "test"
resource_group_name = azurerm_resource_group.test.name
location = azurerm_resource_group.test.location
os_type = "Linux"
sku_name = "F1"
}
resource "azurerm_app_service" "test" {
name = "sofcvlepsaipd"
location = azurerm_resource_group.test.location
resource_group_name = azurerm_resource_group.test.name
app_service_plan_id = azurerm_service_plan.test.id
site_config {
use_32_bit_worker_process = true
}
}
I MUST STRESS THAT THIS ISN'T BEST PRACTICE AS THE azurerm_app_service IS GOING TO BE REMOVED IN THE NEXT VERSION. THIS SEEMS TO INDICATE THAT TERRAFORM WONT BE ABLE TO CREATE FREE TIER APP SERVICES IN THE NEXT UPDATE.
If someone knows how to do this with azurerm_linux_web_app or knows a better approach to this let me know.

Answer 2

I just encountered a similar issue, "always_on" setting defaults to true, but that is not supported in the free tier. As stated here, you must explicitly set it to false when using free tier
resource "azurerm_linux_web_app" "test" {
name = "testazurermjay"
resource_group_name = azurerm_resource_group.test.name
location = azurerm_service_plan.test.location
service_plan_id = azurerm_service_plan.test.id
site_config {
always_on = false
}
}
