Terraform (and AzureRM Provider) Version Terraform v = 0.13.3 azurerm provider v = 2.32.0

Affected Resource(s)

resource "azurerm_kubernetes_cluster_node_pool" "windows" {
count = var.enable_windows_pool ? 1 : 0
name = "win"
kubernetes_cluster_id = azurerm_kubernetes_cluster.gdo-aks.id
os_type = "Windows"
vm_size = var.windows_node_size
enable_auto_scaling = true
min_count = 1
max_count = 1
vnet_subnet_id = azurerm_subnet.aks-sn2.id
}

Actual Behavior

When this runs you will get the error Error: max_count must be >= min_count

As you can see that they are equal so this should run.

When you set the same for the default node_pool in the azurerm_kubernetes_cluster this will work fine.

Steps to Reproduce

In the azurerm_kubernetes_cluster_node_pool set min_count and max_count to teh same value

1. terraform apply

Important Factoids

I have looked through the code for azurerm_kubernetes_cluster_node_pool and see the following on lines 354 to line 356

	if minCount >= maxCount {
		return fmt.Errorf("`max_count` must be >= `min_count`")
	}

Where as if you view this in the code for the azurerm_kubernetes_cluster resource you will see

            if minCount > maxCount {
		return nil, fmt.Errorf("`max_count` must be >= `min_count`")
	}

Hense it works for the default node pool.
