Terraform-provider-azurerm: azurerm_app_service returns 409 error "Unknown service error"

[r3dlin3]

Hi,

I cannot create an Azure App Service using terraform and azure cli. I have tested both v1 (nodejs) and v2 (python) of Azure CLI.
The App Service Plan (and Resource Group) is correctly created.

Terraform Version

Terraform v0.10.6
provider.azurerm: version = "~> 0.3"

Azure CLI 2.0

azure-cli (2.0.20)
...
appservice (0.1.19)
...
resource (2.0.17)

Affected Resource(s)

• azurerm_app_service

Terraform Configuration Files

variable "default_location" {
   default = "West Europe"
}

variable "appserviceplan_name" {
   default =   "api"
}

variable "appservice_name" {
   default =   "api"
}

resource "azurerm_resource_group" "test" {
  name     = "testResourceGroup1"
  location = "${var.default_location}"
}

locals {
    suffix_asp = "${replace(format("%.24s", lower(base64sha256("${azurerm_resource_group.test.id}/${var.appserviceplan_name}"))),"/[+-_]","")}"
    appserviceplan_name = "${lower(format("asp-%s-%s",var.appserviceplan_name,local.suffix_asp))}"
    suffix_as = "${replace(format("%.24s", lower(base64sha256("${azurerm_resource_group.test.id}/${var.appservice_name}"))),"/[+-_]","")}"
    appservice_name = "${substr(lower(format("as-%s-%s",var.appservice_name,local.suffix_as)),0,24)}"
}

resource "azurerm_app_service_plan" "test" {
  name                = "${local.appserviceplan_name}"
  location            = "${azurerm_resource_group.test.location}"
  resource_group_name = "${azurerm_resource_group.test.name}"
  sku {
    tier = "Free"
    size = "F1"
  }
}

resource "azurerm_app_service" "test" {
  name                = "${local.appservice_name}"
  location            = "${azurerm_resource_group.test.location}"
  resource_group_name = "${azurerm_resource_group.test.name}"
  app_service_plan_id = "${azurerm_app_service_plan.test.id}"
  site_config {
     dotnet_framework_version = "v4.0"
  }
}

Debug Output

https://gist.github.com/r3dlin3/fca830182646459bc40242a3ed2f76ce

Expected Behavior

I would expect the creation of an app service over the app service plan.

Actual Behavior

Based on the provided terraform file, the RG and the App Service Plan are created without the App Service.

Steps to Reproduce

1. terraform apply

Important Factoids

I'm trying to use a Free plan.

Hey @r3dlin3

Thanks for opening this issue.

Taking a look into this - this appears to be a duplicate of #394 where the Azure API returns a 409 if always_on is specified in the request when using a non-Premium SKU; as such I'm going to close this issue in favour of #394 to be able to keep updates in a single issue.

Thanks!

Hi,
Thanks for your reply.
I confirm that instanciating an App Service over a S1 App Service Plan works. So this is a duplicate.

[tombuildsstuff]

@r3dlin3 I took a look into this issue today and discovered this is to do with the use_32_bit_worker_process field - which needs to be set to true for a Free/Shared tier SKU (as been detailed in #394) - would you be able to take a look and see if that solves your issue? I've opened PR #550 (which has since been merged) to update the documentation to explain this.

Thanks!

Hi,
Sorry for the delay!
I confirm you that with use_32_bit_worker_process = true on the app service over a Free app service plan, it works.
However, I do not know the consequences of this setting...
