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):

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:

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.

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

Inputs

Name	Description	Type	Default	Required
additional_tag_map	Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id. 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	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
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, except for attributes, tags, and additional_tag_map, which are merged.	any	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "descriptor_formats": {}, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "labels_as_tags": [ "unset" ], "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {}, "tenant": null }	no
delimiter	Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
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 {<br/> format = string<br/> labels = list(string)<br/>} (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	Set to false to prevent the module from creating any resources	bool	null	no
environment	ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'	string	null	no
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	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	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	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	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
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
namespace	ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique	string	null	no
quotas	Map of quotas to set. Map keys are arbitrary and are used to allow Atmos to merge configurations. Delete an inherited quota by setting its key's value to null. You only need to provide one of either name or code for each of "service" and "quota". If you provide both, the code will be used.	map(object({ service_name = optional(string) service_code = optional(string) quota_name = optional(string) quota_code = optional(string) value = number }))	{}	no
regex_replace_chars	Terraform regular expression (regex) string. 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	AWS Region	string	n/a	yes
stage	ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'	string	null	no
tags	Additional tags (e.g. {'BusinessUnit': 'XYZ'}). Neither the tag keys nor the tag values will be modified by this module.	map(string)	{}	no
tenant	ID element _(Rarely used, not included by default)_. A customer identifier, indicating who this instance of a resource is for	string	null	no
