# Short description of this project
description: |-
  This component is responsible for requesting service quota increases. We recommend making requests here rather than in
  `account-settings` because `account-settings` is a restricted component that can only be applied by SuperAdmin.

  ## Usage

  **Stack Level**: Global and Regional (depending on quota)

  Global resources must be provisioned in `us-east-1`. Put them in the `gbl` stack, but set `region: us-east-1` in the
  `vars` section.

  You can refer to services either by their exact full name (e.g.
  `service_name: "Amazon Elastic Compute Cloud (Amazon EC2)"`) or by the service code (e.g. `service_code: "ec2"`).
  Similarly, you can refer to quota names either by their exact full name (e.g. `quota_name: "EC2-VPC Elastic IPs"`) or by
  the quota code (e.g. `quota_code: "L-0263D0A3"`).

  You can find service codes and full names via the AWS CLI (be sure to use the correct region):

  ```bash
  aws --region us-east-1 service-quotas list-services
  ```

  You can find quota codes and full names, and also whether the quotas are adjustable or global, via the AWS CLI, but you
  will need the service code from the previous step:

  ```bash
  aws --region us-east-1 service-quotas list-service-quotas --service-code ec2
  ```

  If you make a request to raise a quota, the output will show the requested value as `value` while the request is
  pending.

  ### Special usage Notes

  Even though the Terraform will submit the support request, you may need to follow up with AWS support to get the request
  approved, via the AWS console or email.

  #### Resources are destroyed on change

  Because the AWS API often returns default values rather than configured or applicable values for a given quota, we have
  to ignore the value returned by the API or else face perpetual drift. To allow us to change the value in the future,
  even though we are ignoring it, we encode the value in the resource key, so that a change of value will result in a new
  resource being created and the old one being destroyed. Destroying the old resource has no actual effect (it does not
  even close an open request), so it is safe to do.

  ### Example

  Here's an example snippet for how to use this component.

  ```yaml
  components:
    terraform:
      account-quotas:
        vars:
          quotas:
            vpcs-per-region:
              service_code: vpc
              quota_name: "VPCs per Region"
              value: 10
            vpc-elastic-ips:
              service_code: ec2
              quota_name: "EC2-VPC Elastic IPs"
              value: 10
  ```

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 |
  | <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.

  | <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 |

  | <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 |
