| | create\_service\_account | Defines if service account specified to run nodes should be created. | bool | `"true"` | no | | ||
| | database\_encryption | Application-layer Secrets Encryption settings. The object format is {state = string, key_name = string}. Valid values of state are: "ENCRYPTED"; "DECRYPTED". key_name is the name of a CloudKMS key. | object | `<list>` | no | | ||
