organizational-unit

This component is responsible for creating or importing a single AWS Organizations Organizational Unit (OU).

Unlike the monolithic account component which manages the entire organization hierarchy, this component follows the single-resource pattern - it only manages a single OU.

note

This component should be deployed from the management/root account as it creates OUs within AWS Organizations.

Usage

Stack Level: Global (deployed in the management/root account)

Basic Usage

components:
  terraform:
    aws-organizational-unit/core:
      metadata:
        component: aws-organizational-unit
      vars:
        name: core
        parent_id: !terraform.output aws-organization organization_root_id

Using Remote State for Parent ID

Reference the organization root dynamically:

components:
  terraform:
    aws-organizational-unit/core:
      metadata:
        component: aws-organizational-unit
      vars:
        name: core
        parent_id: !terraform.output aws-organization organization_root_id

    aws-organizational-unit/plat:
      metadata:
        component: aws-organizational-unit
      vars:
        name: plat
        parent_id: !terraform.output aws-organization organization_root_id

Importing an Existing OU

To import an existing Organizational Unit:

Get the OU ID:

aws organizations list-organizational-units-for-parent --parent-id r-xxxx

Set the import_resource_id variable:

components:
  terraform:
    aws-organizational-unit/core:
      metadata:
        component: aws-organizational-unit
      vars:
        name: core
        parent_id: "r-xxxx"
        import_resource_id: "ou-xxxx-xxxxxxxx"

Run atmos terraform apply

After successful import, you can remove the import_resource_id variable.

Note: If you don't need import functionality, you can exclude imports.tf when vendoring the component.

This component is part of a suite of single-resource components for AWS Organizations:

Component	Purpose
`aws-organization`	Creates/imports the AWS Organization
`aws-organizational-unit`	Creates/imports a single OU (this component)
`aws-account`	Creates/imports a single AWS Account
`aws-account-settings`	Configures account settings
`aws-scp`	Creates/imports Service Control Policies

Variables

Required Variables

parent_id (string) required: The ID of the parent organizational unit or organization root
region (string) required: AWS Region

Optional Variables

import_resource_id (string) optional

The ID of an existing Organizational Unit to import. If set, the OU will be imported rather than created.

Default value: null

Context Variables

The following variables are defined in the context.tf file of this module and part of the terraform-null-label pattern.

additional_tag_map (map(string)) optional

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.

Required: No

Default value: { }

attributes (list(string)) optional

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.

Required: No

Default value: [ ]

context (any) optional

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.

Required: No

Default value:

{
  "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
}

delimiter (string) optional

Delimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.

Required: No

Default value: null

descriptor_formats (any) optional

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).

Required: No

Default value: { }

enabled (bool) optional

Set to false to prevent the module from creating any resources
Required: No

Default value: null

environment (string) optional

ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'
Required: No

Default value: null

id_length_limit (number) optional

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.

Required: No

Default value: null

label_key_case (string) optional

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.

Required: No

Default value: null

label_order (list(string)) optional

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.

Required: No

Default value: null

label_value_case (string) optional

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.

Required: No

Default value: null

labels_as_tags (set(string)) optional

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.

Required: No

Default value:

[
  "default"
]

name (string) optional

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.

Required: No

Default value: null

namespace (string) optional

ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique
Required: No

Default value: null

regex_replace_chars (string) optional

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.

Required: No

Default value: null

stage (string) optional

ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'

Neither the tag keys nor the tag values will be modified by this module.

Required: No

tenant (string) optional

ID element (Rarely used, not included by default). A customer identifier, indicating who this instance of a resource is for
Required: No
