Azure - azurerm_app_service - Unable to apply health_check_path in site_config

[ghost]

This issue was originally opened by @PrykorTech as hashicorp/terraform#26256. It was migrated here as a result of the provider split. The original body of the issue is below.

Hi Team,

We've been looking at using health_check_path for azurerm_app_service however the property does not seem to work. I know its only been in production in Azure for a few weeks now, wondering if its functional within terraform?

Terraform Version

0.13.2

  backend "azurerm" {

    container_name       = "contact-dev-tstate"
    key                  = "history-dev-terraform.tfstate"
  }

  required_version = ">= 0.12"

  site_config {
    health_check_path         = "/contact/history/v1/_status"
    always_on                 = true
    use_32_bit_worker_process = var.use_32_bit_process
  }

  identity {
    type = "SystemAssigned"
  }

  lifecycle {
    ignore_changes = [
      site_config[0].linux_fx_version,
      # deployments are made outside of Terraform
      app_settings,
    ]
    prevent_destroy = true
  }

  tags = {
    sub_type    = var.sub_type
    team_number = var.team_number
  }
}

Expected Behavior

Terraform applies the health check path to the app service

Actual Behavior

Terraform complains An argument named "health_check_path" is not expected here.

Steps to Reproduce

1. terraform init
2. terraform validate

@PrykorTech the field "health_check_path" is only supported in version >= 2.9 through this changelog: https://github.com/terraform-providers/terraform-provider-azurerm/blob/master/CHANGELOG-v2.md#290-may-07-2020 and you are using azurerm v2.5. could you please upgrade your azurerm and have a try? I have tried the latest azurerm and it could success in my local

👋

Since this should be fixed by updating the version of the Azure Provider being used here, I'm going to close this issue for the moment - but please let us know if that doesn't work for you and we'll take another look.

Thanks!
