Incorrect Terraform code sample using list of blocks

[dumitrux]

Issue

There is an error in the Terraform app-service.tf code sample.
The ip_restriction and headers are lists of maps

ip_restriction = [{
  service_tag               = "AzureFrontDoor.Backend"
  ip_address                = null
  virtual_network_subnet_id = null
  action                    = "Allow"
  priority                  = 100
  headers = [{
    x_azure_fdid      = [azurerm_cdn_frontdoor_profile.my_front_door.resource_guid]
    x_fd_health_probe = []
    x_forwarded_for   = []
    x_forwarded_host  = []
  }]
  name = "Allow traffic from Front Door"
}]

Fix

As per the Terraform documentation, the ip_restriction and headerscan be one or more blocks.
Therefore, the code sample should look like this:

ip_restriction {
  service_tag               = "AzureFrontDoor.Backend"
  ip_address                = null
  virtual_network_subnet_id = null
  action                    = "Allow"
  priority                  = 100
  headers {
    x_azure_fdid      = [azurerm_cdn_frontdoor_profile.my_front_door.resource_guid]
    x_fd_health_probe = []
    x_forwarded_for   = []
    x_forwarded_host  = []
  }
  name = "Allow traffic from Front Door"
}

I have tested and the first option does not work with terraform_1.5.4 and azurerm_3.67.0, the second one works.

@dumitrux Thanks. This is a change in a recent AzureRM provider version. The example works as-is when you follow the tutorial and use version 3.27.0 of the provider.

I'll submit a version update shortly - it might take a a bit of time to get updated.

@dumitrux The updated PR has been merged, which means that our docs should update (I think within about 24 hours) :)
