|`network_name` | The name to be given to the internal network that will be generated |
|`use_existing_network`| Use an existing network with the name of `network_name`. `false` by default |
|`network_dns_domain` | (Optional) The dns_domain for the internal network that will be generated |
|`dns_nameservers`| An array of DNS name server names to be used by hosts in the internal subnet. |

|`use_access_ip` | If 1, nodes with floating IPs will transmit internal cluster traffic via floating IPs; if 0 private IPs will be used instead. Default value is 1. |
|`port_security_enabled` | Allow to disable port security by setting this to `false`. `true` by default |
