Azure windows app service with docker container is not getting created properly.

Expected: when we create terraform resource ‘azurerm_windows_web_app’ with ‘application_stack’ block having values such as docker_container_name, docker_container_tag, docker_container_registry. It should create app service with container, having an image as specified in application_stack’ block.

But instead of creating app service with container features, it creates plane app service. Note- Creation happens properly in case of linux app service with container (azurerm_linux_web_app)

Here is the code which is taken from: windows-container

main.tf:

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "example" {
  name     = "${var.prefix}-resources"
  location = var.location
}

resource "azurerm_service_plan" "example" {
  name                = "${var.prefix}-sp"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  os_type             = "Windows"
  sku_name            = "P1v3"
}

resource "azurerm_windows_web_app" "example" {
  name                = "${var.prefix}-container-example"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  service_plan_id     = azurerm_service_plan.example.id

  app_settings = {
    "WEBSITES_ENABLE_APP_SERVICE_STORAGE" = "false"
  }

  site_config {
    application_stack {
      docker_container_name = "jackofallops/azure-containerapps-python-acctest"
      docker_container_tag  = "v0.0.1"
    }
  }
}

variables.tf:

variable "prefix" {
  type        = string
  description = "The prefix used for all resources in this example"
  default = "mywebwincontainrc93"
}

variable "location" {
  type        = string
  description = "The Azure location where all resources in this example should be created"
  default = "West Europe"
}

Root Cause: While analyzing the different aspects of this issue, I exported the json template from azure portal, compared linux & windows json template and came to know that property: Kind is not getting set properly in case of windows app service hence the issue. In this case property: Kind is getting set as: “kind”: “app” while it should be: “kind”: “app,windows,container” While its getting set properly in case of linux app service with container i.e. “kind”: “app,linux,container”,

Refer image–> linux app service with container:

image–> windows app service with container, which is wrong:

Also it can be seen while destroying the resources too:

This issue blocks users to create an azure windows app service with container using terraform, which pulls image from specific container source, either docker or acr.

Terraform Version

1.1.6

AzureRM Provider Version

3.10.0

Affected Resource(s)/Data Source(s)

azurerm_windows_web_app

Terraform Configuration Files

resource "azurerm_windows_web_app" "example" {
  name                = "${var.prefix}-container-example"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  service_plan_id     = azurerm_service_plan.example.id

Debug Output/Panic Output

provided in screenshot

Expected Behaviour

should create azure windows app service container

Actual Behaviour

creating normal azure windows app service

Steps to Reproduce

1. Clone code from : windows-container
2. terraform init
3. terraform plan
4. terraform apply
5. Once resources are created successfully, go to the app service from azure portal. In app service, select option ‘Deployment Center’ from the left side options menu
6. It must show container details along with image details & tag. But its not doing so.
