+- Creating a cluster containing usage nodepool
+
+```hcl
+location = "eastus2"
+resource_group = "Resource_group"
+prefix = "new_kubernetes"
+node_count = 1
+auto_scaling_default_node = false
+node_min_count = null
+node_max_count = null
+default_node_vm_size = "Standard_DS2_v2"
+create_additional_node_pool = false 
+
+if "enable_auto_scaling" is "true" then pass values in "min_count" and "max_count".
+if "create_additional_node_pool" is "true" only then "additional_node_pool" will get created.
+
+additional_node_pools = {
+  "pool1" = {
+	vm_size = "Standard_DS2_v2"
+    os_disk_size_gb = 100
+	enable_auto_scaling = false 
+    availability_zones  = ["1", "2", "3"]
+    node_count          = 1
+    min_count           = null
+    max_count           = null
+    max_pods            = 110
