| no | +| [data\_classification](#input\_data\_classification) | Used to identify the data classification of the resource, e.g 1-5 | `string` | `"n/a"` | no | +| [data\_type](#input\_data\_type) | The tag data\_type | `string` | `"None"` | no | +| [delimiter](#input\_delimiter) | Delimiter to be used between ID elements.
Defaults to `-` (hyphen). Set to `""` to use no delimiter at all. | `string` | `null` | no | +| [descriptor\_formats](#input\_descriptor\_formats) | Describe additional descriptors to be output in the `descriptors` output map.
Map of maps. Keys are names of descriptors. Values are maps of the form
`{
format = string
labels = list(string)
}`
(Type is `any` so the map values can later be enhanced to provide additional options.)
`format` is a Terraform format string to be passed to the `format()` function.
`labels` is a list of labels, in order, to pass to `format()` function.
Label values will be normalized before being passed to `format()` so they will be
identical to how they appear in `id`.
Default is `{}` (`descriptors` output will be empty). | `any` | `{}` | no | +| [enabled](#input\_enabled) | Set to false to prevent the module from creating any resources | `bool` | `null` | no | +| [environment](#input\_environment) | ID element. Usually used to indicate role, e.g. 'prd', 'dev', 'test', 'preprod', 'prod', 'uat' | `string` | `null` | no | +| [environment\_variables](#input\_environment\_variables) | Values to set in the Lambda function environment | `map(string)` | `{}` | no | +| [function\_description](#input\_function\_description) | The description for the Lambda function | `string` | n/a | yes | +| [function\_name](#input\_function\_name) | The name of the Lambda function | `string` | `"uk-forwarder"` | no | +| [handler\_prefix](#input\_handler\_prefix) | The prefix for the Lambda handler function | `string` | n/a | yes | +| [id\_length\_limit](#input\_id\_length\_limit) | Limit `id` to this many characters (minimum 6).
Set to `0` for unlimited length.
Set to `null` for keep the existing setting, which defaults to `0`.
Does not affect `id_full`. | `number` | `null` | no | +| [label\_key\_case](#input\_label\_key\_case) | Controls the letter case of the `tags` keys (label names) for tags generated by this module.
Does not affect keys of tags passed in via the `tags` input.
Possible values: `lower`, `title`, `upper`.
Default value: `title`. | `string` | `null` | no | +| [label\_order](#input\_label\_order) | The order in which the labels (ID elements) appear in the `id`.
Defaults to ["namespace", "environment", "stage", "name", "attributes"].
You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present. | `list(string)` | `null` | no | +| [label\_value\_case](#input\_label\_value\_case) | Controls the letter case of ID elements (labels) as included in `id`,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the `tags` input.
Possible values: `lower`, `title`, `upper` and `none` (no transformation).
Set this to `title` and set `delimiter` to `""` to yield Pascal Case IDs.
Default value: `lower`. | `string` | `null` | no | +| [labels\_as\_tags](#input\_labels\_as\_tags) | Set of labels (ID elements) to include as tags in the `tags` output.
Default is to include all labels.
Tags with empty values will not be included in the `tags` output.
Set to `[]` to suppress all generated tags.
**Notes:**
The value of the `name` tag, if included, will be the `id`, not the `name`.
Unlike other `null-label` inputs, the initial setting of `labels_as_tags` cannot be
changed in later chained modules. Attempts to change it will be silently ignored. | `set(string)` | 
[
  "default"
]
| no | +| [layers](#input\_layers) | List of Lambda Layer ARNs to attach to the function | `list(string)` | `[]` | no | +| [name](#input\_name) | ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'.
This is the only ID element not also included as a `tag`.
The "name" tag is set to the full `id` string. There is no tag with the value of the `name` input. | `string` | `null` | no | +| [on\_off\_pattern](#input\_on\_off\_pattern) | Used to turn resources on and off based on a time pattern | `string` | `"n/a"` | no | +| [owner](#input\_owner) | The name and or NHS.net email address of the service owner | `string` | `"None"` | no | +| [project](#input\_project) | ID element.

Characters matching the regex will be removed from the ID elements.
If not set, `"/[^a-zA-Z0-9-]/"` is used to remove all characters other than hyphens, letters and digits. | `string` | `null` | no | +| [region](#input\_region) | ID element \_(Rarely used, not included by default)\_. Usually an abbreviation of the selected AWS region e.g. 'uw2', 'ew2' or 'gbl' for resources like IAM roles that have no region | `string` | `null` | no | +| [service](#input\_service) | ID element. Usually an abbreviation of your service directorate name, e.g. 'bcss' or 'csms', to help ensure generated IDs are globally unique | `string` | `null` | no | +| [service\_category](#input\_service\_category) | The tag service\_category | `string` | `"n/a"` | no | +| [source\_path](#input\_source\_path) | Optional override for the directory containing the Lambda's source code.
Resolved relative to the root module (the stack) at plan/apply time.

When null (default), the module falls back to the historical layout
`../../lambdas//`, which expects sources under a top-level
`infrastructure_v2/lambdas/` directory.

Set this to keep a stack's Lambda source co-located with the stack,
e.g. source\_path = "lambdas/slack-notifier". | `string` | `null` | no | +| [stack](#input\_stack) | ID element.
