| 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 | string | n/a | yes | | ||
| ip\_range\_pods | The secondary ip range to use for pods | string | n/a | yes | | ||
| ip\_range\_services | The secondary ip range to use for pods | string | n/a | yes | | ||
| network | The VPC network to host the cluster in | string | n/a | yes | | ||
| project\_id | The project ID to host the cluster in | string | n/a | yes | | ||
| region | The region to host the cluster in | string | n/a | yes | | ||
| subnetwork | The subnetwork to host the cluster in | string | n/a | yes | | ||
| zones | The zone to host the cluster in (required if is a zonal cluster) | list | n/a | yes | | ||
|
||
## Outputs | ||
|
||
| Name | Description | | ||
|------|-------------| | ||
| ca\_certificate | | | ||
| client\_token | | | ||
| cluster\_name | Cluster name | | ||

| location | | | ||
| master\_kubernetes\_version | The master Kubernetes version | | ||
| network | | | ||
| project\_id | | | ||
| region | | | ||
