+# Simple Regional Cluster
+
+This example illustrates how to create a simple cluster.
+
+<!-- BEGINNING OF PRE-COMMIT-TERRAFORM DOCS HOOK -->
+## Inputs
+
+| Name | Description | Type | Default | Required |
+|------|-------------|------|---------|:--------:|
+| cluster\_name\_suffix | A suffix to append to the default cluster name | `string` | `""` | no |
+| compute\_engine\_service\_account | Service account to associate to the nodes in the cluster | `any` | n/a | yes |
+| enable\_binary\_authorization | Enable BinAuthZ Admission controller | `bool` | `false` | no |
+| gateway\_api\_channel | The gateway api channel of this cluster. Accepted values are `CHANNEL_STANDARD` and `CHANNEL_DISABLED`. | `string` | `null` | no |
+| ip\_range\_pods | The secondary ip range to use for pods | `any` | n/a | yes |
+| ip\_range\_services | The secondary ip range to use for services | `any` | n/a | yes |
+| network | The VPC network to host the cluster in | `any` | n/a | yes |
+| project\_id | The project ID to host the cluster in | `any` | n/a | yes |
+| region | The region to host the cluster in | `any` | n/a | yes |
+| skip\_provisioners | Flag to skip local-exec provisioners | `bool` | `false` | no |
+| subnetwork | The subnetwork to host the cluster in | `any` | n/a | yes |
+
+## Outputs
+
+| Name | Description |
+|------|-------------|
+| ca\_certificate | n/a |
+| client\_token | n/a |
+| cluster\_name | Cluster name |
+| ip\_range\_pods | The secondary IP range used for pods |
+| ip\_range\_services | The secondary IP range used for services |
+| kubernetes\_endpoint | n/a |
+| location | n/a |
+| master\_kubernetes\_version | The master Kubernetes version |
+| network | n/a |
+| project\_id | n/a |
+| region | n/a |
+| service\_account | The default service account used for running nodes. |
+| subnetwork | n/a |
+| zones | List of zones in which the cluster resides |
