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 | +| [additional\_tags](#input\_additional\_tags) | Additional tags to apply to the ingress load balancer. | `map(string)` | `{}` | no | +| [attributes](#input\_attributes) | ID element. Additional attributes (e.g. `workers` or `cluster`) to add to `id`,
in the order they appear in the list. New attributes are appended to the
end of the list. The elements of the list are joined by the `delimiter`
and treated as a single ID element. | `list(string)` | `[]` | no | +| [class\_name](#input\_class\_name) | Class name for default ingress | `string` | `"default"` | no | +| [context](#input\_context) | Single object for setting entire context at once.

| 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 | +| [eks\_component\_name](#input\_eks\_component\_name) | The name of the eks component | `string` | `"eks/cluster"` | no | +| [enabled](#input\_enabled) | Set to false to prevent the module from creating any resources | `bool` | `null` | no | +| [environment](#input\_environment) | ID element.

Set to `0` for unlimited length.

Does not affect `id_full`. | `number` | `null` | no | +| [ip\_address\_type](#input\_ip\_address\_type) | IP address type for default ingress, one of `ipv4` or `dualstack`. | `string` | `"dualstack"` | no | +| [is\_default](#input\_is\_default) | Set `true` to make this the default IngressClass. There should only be one default per cluster. | `bool` | `false` | no | +| [kube\_data\_auth\_enabled](#input\_kube\_data\_auth\_enabled) | If `true`, use an `aws_eks_cluster_auth` data source to authenticate to the EKS cluster.
Disabled by `kubeconfig_file_enabled` or `kube_exec_auth_enabled`. | `bool` | `false` | no | +| [kube\_exec\_auth\_aws\_profile](#input\_kube\_exec\_auth\_aws\_profile) | The AWS config profile for `aws eks get-token` to use | `string` | `""` | no | +| [kube\_exec\_auth\_aws\_profile\_enabled](#input\_kube\_exec\_auth\_aws\_profile\_enabled) | If `true`, pass `kube_exec_auth_aws_profile` as the `profile` to `aws eks get-token` | `bool` | `false` | no | +| [kube\_exec\_auth\_enabled](#input\_kube\_exec\_auth\_enabled) | If `true`, use the Kubernetes provider `exec` feature to execute `aws eks get-token` to authenticate to the EKS cluster.
Disabled by `kubeconfig_file_enabled`, overrides `kube_data_auth_enabled`. | `bool` | `true` | no | +| [kube\_exec\_auth\_role\_arn](#input\_kube\_exec\_auth\_role\_arn) | The role ARN for `aws eks get-token` to use | `string` | `""` | no | +| [kube\_exec\_auth\_role\_arn\_enabled](#input\_kube\_exec\_auth\_role\_arn\_enabled) | If `true`, pass `kube_exec_auth_role_arn` as the role ARN to `aws eks get-token` | `bool` | `true` | no | +| [kubeconfig\_context](#input\_kubeconfig\_context) | Context to choose from the Kubernetes config file.
If supplied, `kubeconfig_context_format` will be ignored. | `string` | `""` | no | +| [kubeconfig\_context\_format](#input\_kubeconfig\_context\_format) | A format string to use for creating the `kubectl` context name when
`kubeconfig_file_enabled` is `true` and `kubeconfig_context` is not supplied.
Must include a single `%s` which will be replaced with the cluster name. | `string` | `""` | no | +| [kubeconfig\_exec\_auth\_api\_version](#input\_kubeconfig\_exec\_auth\_api\_version) | The Kubernetes API version of the credentials returned by the `exec` auth plugin | `string` | `"client.authentication.k8s.io/v1beta1"` | no | +| [kubeconfig\_file](#input\_kubeconfig\_file) | The Kubernetes provider `config_path` setting to use when `kubeconfig_file_enabled` is `true` | `string` | `""` | no | +| [kubeconfig\_file\_enabled](#input\_kubeconfig\_file\_enabled) | If `true`, configure the Kubernetes provider with `kubeconfig_file` and use that kubeconfig file for authenticating to the EKS cluster | `bool` | `false` | no | +| [label\_key\_case](#input\_label\_key\_case) | Controls the letter case of the `tags` keys (label names) for tags generated by this module.

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.
