+# Regional Private Cluster with node pool and oauth scopes
+
+This example illustrates how to create a private cluster with node pool specifications, oauth scopes along with required network and subnet creation.
+
+<!-- BEGINNING OF PRE-COMMIT-TERRAFORM DOCS HOOK -->
+## Inputs
+
+| Name | Description | Type | Default | Required |
+|------|-------------|:----:|:-----:|:-----:|
+| project\_id | The project ID to host the cluster in | string | n/a | yes |
+
+## Outputs
+
+| Name | Description |
+|------|-------------|
+| ca\_certificate | Cluster ca certificate (base64 encoded) |
+| cluster\_name | Cluster name |
+| endpoint | Cluster endpoint |
+| horizontal\_pod\_autoscaling\_enabled | Whether horizontal pod autoscaling enabled |
+| http\_load\_balancing\_enabled | Whether http load balancing enabled |
+| location | Cluster location (region if regional cluster, zone if zonal cluster) |
+| logging\_service | Logging service used |
+| master\_authorized\_networks\_config | Networks from which access to master is permitted |
+| master\_version | Current master kubernetes version |
+| min\_master\_version | Minimum master kubernetes version |
+| monitoring\_service | Monitoring service used |
+| network\_module | network module output |
+| network\_policy\_enabled | Whether network policy enabled |
+| node\_pools\_names | List of node pools names |
+| node\_pools\_versions | List of node pools versions |
+| region | Cluster region |
+| service\_account | The service account to default running nodes as if not overridden in `node_pools`. |
+| subnets\_ips | The IP and cidrs of the subnets being created |
+| subnets\_secondary\_ranges | The secondary ranges associated with these subnets |
+| type | Cluster type (regional / zonal) |
+| zones | List of zones in which the cluster resides |
+
+<!-- END OF PRE-COMMIT-TERRAFORM DOCS HOOK -->
