This is for some rare cases where resources want additional configuration of tags
and therefore take a list of maps with tag key, value, and additional configuration. | `map(string)` | `{}` | no | +| [attributes](#input\_attributes) | ID element. Additional attributes (e.g. `workers` or `cluster`) to add to `id`,

and treated as a single ID element. | `list(string)` | `[]` | no | +| [context](#input\_context) | Single object for setting entire context at once.
See description of individual variables for details.
Leave string and numeric variables as `null` to use default value.
Individual variable settings (non-null) override settings in context object,

| no | +| [create\_iam\_service\_linked\_role](#input\_create\_iam\_service\_linked\_role) | Whether to create `AWSServiceRoleForAmazonElasticsearchService` service-linked role.
Set this to `false` if you already have an ElasticSearch cluster created in the AWS account and `AWSServiceRoleForAmazonElasticsearchService` already exists.

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 | +| [dns\_delegated\_environment\_name](#input\_dns\_delegated\_environment\_name) | The name of the environment where the `dns-delegated` component is deployed | `string` | `"gbl"` | no | +| [domain\_hostname\_enabled](#input\_domain\_hostname\_enabled) | Explicit flag to enable creating a DNS hostname for ES.

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 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)` |
