-## Inputs
-
-| Name | Description | Type | Default | Required |
-|------|-------------|:----:|:-----:|:-----:|
-| basic\_auth\_password | The password to be used with Basic Authentication. | string | `""` | no |
-| basic\_auth\_username | The username to be used with Basic Authentication. An empty value will disable Basic Authentication, which is the recommended configuration. | string | `""` | no |
-| description | The description of the cluster | string | `""` | no |
-| disable\_legacy\_metadata\_endpoints | Disable the /0.1/ and /v1beta1/ metadata server endpoints on the node. Changing this value will cause all node pools to be recreated. | string | `"true"` | no |
-| horizontal\_pod\_autoscaling | Enable horizontal pod autoscaling addon | string | `"true"` | no |
-| http\_load\_balancing | Enable httpload balancer addon | string | `"true"` | no |
-| initial\_node\_count | The number of nodes to create in this cluster's default node pool. | string | `"0"` | no |
-| ip\_masq\_link\_local | Whether to masquerade traffic to the link-local prefix (169.254.0.0/16). | string | `"false"` | no |
-| ip\_masq\_resync\_interval | The interval at which the agent attempts to sync its ConfigMap file from the disk. | string | `"60s"` | no |
-| ip\_range\_pods | The _name_ of the secondary subnet ip range to use for pods | string | n/a | yes |
-| ip\_range\_services | The _name_ of the secondary subnet range to use for services | string | n/a | yes |
-| issue\_client\_certificate | Issues a client certificate to authenticate to the cluster endpoint. To maximize the security of your cluster, leave this option disabled. Client certificates don't automatically rotate and aren't easily revocable. WARNING: changing this after cluster creation is destructive! | string | `"false"` | no |
-| kubernetes\_dashboard | Enable kubernetes dashboard addon | string | `"false"` | no |
-| kubernetes\_version | The Kubernetes version of the masters. If set to 'latest' it will pull latest available version in the selected region. | string | `"latest"` | no |
-| logging\_service | The logging service that the cluster should write logs to. Available options include logging.googleapis.com, logging.googleapis.com/kubernetes (beta), and none | string | `"logging.googleapis.com"` | no |
-| maintenance\_start\_time | Time window specified for daily maintenance operations in RFC3339 format | string | `"05:00"` | no |
-| master\_authorized\_networks\_config | The desired configuration options for master authorized networks. Omit the nested cidr_blocks attribute to disallow external access (except the cluster node IPs, which GKE automatically whitelists)<br><br>  ### example format ###   master_authorized_networks_config = [{     cidr_blocks = [{       cidr_block   = "10.0.0.0/8"       display_name = "example_network"     }],   }] | list | `<list>` | no |
-| monitoring\_service | The monitoring service that the cluster should write metrics to. Automatically send metrics from pods in the cluster to the Google Cloud Monitoring API. VM metrics will be collected by Google Compute Engine regardless of this setting Available options include monitoring.googleapis.com, monitoring.googleapis.com/kubernetes (beta) and none | string | `"monitoring.googleapis.com"` | no |
-| name | The name of the cluster (required) | string | n/a | yes |
-| network | The VPC network to host the cluster in (required) | string | n/a | yes |
-| network\_policy | Enable network policy addon | string | `"false"` | no |
-| network\_policy\_provider | The network policy provider. | string | `"CALICO"` | no |
-| network\_project\_id | The project ID of the shared VPC's host (for shared vpc support) | string | `""` | no |
-| node\_pools | List of maps containing node pools | list | `<list>` | no |
-| node\_pools\_labels | Map of maps containing node labels by node-pool name | map | `<map>` | no |
-| node\_pools\_metadata | Map of maps containing node metadata by node-pool name | map | `<map>` | no |
-| node\_pools\_oauth\_scopes | Map of lists containing node oauth scopes by node-pool name | map | `<map>` | no |

-| project\_id | The project ID to host the cluster in (required) | string | n/a | yes |
-| region | The region to host the cluster in (required) | string | n/a | yes |
-| regional | Whether is a regional cluster (zonal cluster if set false. WARNING: changing this after cluster creation is destructive!) | string | `"true"` | no |
-| remove\_default\_node\_pool | Remove default node pool while setting up the cluster | string | `"false"` | no |
-| service\_account | The service account to run nodes as if not overridden in `node_pools`. The default value will cause a cluster-specific service account to be created. | string | `"create"` | no |
-| stub\_domains | Map of stub domains and their resolvers to forward DNS queries for a certain domain to an external DNS server | map | `<map>` | no |
-| subnetwork | The subnetwork to host the cluster in (required) | string | n/a | yes |
