115+
| <a name="input_additional_tag_map"></a> [additional\_tag\_map](#input\_additional\_tag\_map) | Additional key-value pairs to add to each map in `tags_as_list_of_maps`. Not added to `tags` or `id`.<br/>This is for some rare cases where resources want additional configuration of tags<br/>and therefore take a list of maps with tag key, value, and additional configuration. | `map(string)` | `{}` | no |
116+
| <a name="input_attributes"></a> [attributes](#input\_attributes) | ID element. Additional attributes (e.g. `workers` or `cluster`) to add to `id`,<br/>in the order they appear in the list. New attributes are appended to the<br/>end of the list. The elements of the list are joined by the `delimiter`<br/>and treated as a single ID element. | `list(string)` | `[]` | no |
117+
| <a name="input_context"></a> [context](#input\_context) | Single object for setting entire context at once.<br/>See description of individual variables for details.<br/>Leave string and numeric variables as `null` to use default value.<br/>Individual variable settings (non-null) override settings in context object,<br/>except for attributes, tags, and additional\_tag\_map, which are merged. | `any` | <pre>{<br/> "additional_tag_map": {},<br/> "attributes": [],<br/> "delimiter": null,<br/> "descriptor_formats": {},<br/> "enabled": true,<br/> "environment": null,<br/> "id_length_limit": null,<br/> "label_key_case": null,<br/> "label_order": [],<br/> "label_value_case": null,<br/> "labels_as_tags": [<br/> "unset"<br/> ],<br/> "name": null,<br/> "namespace": null,<br/> "regex_replace_chars": null,<br/> "stage": null,<br/> "tags": {},<br/> "tenant": null<br/>}</pre> | no |
118+
| <a name="input_delimiter"></a> [delimiter](#input\_delimiter) | Delimiter to be used between ID elements.<br/>Defaults to `-` (hyphen). Set to `""` to use no delimiter at all. | `string` | `null` | no |
119+
| <a name="input_descriptor_formats"></a> [descriptor\_formats](#input\_descriptor\_formats) | Describe additional descriptors to be output in the `descriptors` output map.<br/>Map of maps. Keys are names of descriptors. Values are maps of the form<br/>`{<br/> format = string<br/> labels = list(string)<br/>}`<br/>(Type is `any` so the map values can later be enhanced to provide additional options.)<br/>`format` is a Terraform format string to be passed to the `format()` function.<br/>`labels` is a list of labels, in order, to pass to `format()` function.<br/>Label values will be normalized before being passed to `format()` so they will be<br/>identical to how they appear in `id`.<br/>Default is `{}` (`descriptors` output will be empty). | `any` | `{}` | no |
120+
| <a name="input_enabled"></a> [enabled](#input\_enabled) | Set to false to prevent the module from creating any resources | `bool` | `null` | no |

125+
| <a name="input_kms_key_arn"></a> [kms\_key\_arn](#input\_kms\_key\_arn) | The ARN of the KMS Key to use when encrypting log data.<br/><br/>Please note, after the AWS KMS CMK is disassociated from the log group, AWS CloudWatch Logs stops encrypting newly ingested data for the log group.<br/><br/>All previously ingested data remains encrypted, and AWS CloudWatch Logs requires permissions for the CMK whenever the encrypted data is requested. | `string` | `""` | no |
126+
| <a name="input_label_key_case"></a> [label\_key\_case](#input\_label\_key\_case) | Controls the letter case of the `tags` keys (label names) for tags generated by this module.<br/>Does not affect keys of tags passed in via the `tags` input.<br/>Possible values: `lower`, `title`, `upper`.<br/>Default value: `title`. | `string` | `null` | no |

| <a name="input_label_value_case"></a> [label\_value\_case](#input\_label\_value\_case) | Controls the letter case of ID elements (labels) as included in `id`,<br/>set as tag values, and output by this module individually.<br/>Does not affect values of tags passed in via the `tags` input.<br/>Possible values: `lower`, `title`, `upper` and `none` (no transformation).<br/>Set this to `title` and set `delimiter` to `""` to yield Pascal Case IDs.<br/>Default value: `lower`. | `string` | `null` | no |
129+
| <a name="input_labels_as_tags"></a> [labels\_as\_tags](#input\_labels\_as\_tags) | Set of labels (ID elements) to include as tags in the `tags` output.<br/>Default is to include all labels.<br/>Tags with empty values will not be included in the `tags` output.<br/>Set to `[]` to suppress all generated tags.<br/>**Notes:**<br/> The value of the `name` tag, if included, will be the `id`, not the `name`.<br/> Unlike other `null-label` inputs, the initial setting of `labels_as_tags` cannot be<br/> changed in later chained modules.
