This component is responsible for provisioning information only: it simply populates Terraform state with data (account ids, groups, and roles) that other root modules need via outputs.

Pre-requisites

Usage

Stack Level: Global

Here is an example snippet for how to use this component. Include this snippet in the stack configuration for the management account (typically root) in the management tenant/OU (usually something like mgmt or core) in the global region (gbl). You can include the content directly, or create a stacks/catalog/account-map.yaml file and import it from there.

components:
  terraform:
    account-map:
      vars:
        enabled: true
        # Set profiles_enabled to false unless we are using AWS config profiles for Terraform access.
        # When profiles_enabled is false, role_arn must be provided instead of profile in each terraform component provider.
        # This is automatically handled by the component's `provider.tf` file in conjunction with
        # the `account-map/modules/iam-roles` module.
        profiles_enabled: false
        root_account_aws_name: "aws-root"
        root_account_account_name: root
        identity_account_account_name: identity
        dns_account_account_name: dns
        audit_account_account_name: audit

        # The following variables contain `format()` strings that take the labels from `null-label`
        # as arguments in the standard order. The default values are shown here, assuming
        # the `null-label.label_order` is
        # ["namespace", "tenant", "environment", "stage", "name", "attributes"]
        # Note that you can rearrange the order of the labels in the template by
        # using [explicit argument indexes](https://pkg.go.dev/fmt#hdr-Explicit_argument_indexes) just like in `go`.

        #  `iam_role_arn_template_template` is the template for the template [sic] used to render Role ARNs.
        #  The template is first used to render a template for the account that takes only the role name.
        #  Then that rendered template is used to create the final Role ARN for the account.
        iam_role_arn_template_template: "arn:%s:iam::%s:role/%s-%s-%s-%s-%%s"
        # `profile_template` is the template used to render AWS Profile names.
        profile_template: "%s-%s-%s-%s-%s"

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
artifacts_account_account_name The short name for the artifacts account string "artifacts" 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
audit_account_account_name The short name for the audit account string "audit" no
aws_config_identity_profile_name The AWS config profile name to use as source_profile for credentials. string null 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,

}
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
dns_account_account_name The short name for the primary DNS account string "dns" 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
iam_role_arn_template_template The template for the template used to render Role ARNs.
The template is first used to render a template for the account that takes only the role name.
Then that rendered template is used to create the final Role ARN for the account.
Default is appropriate when using tenant and default label order with null-label.
Use "arn:%s:iam::%s:role/%s-%s-%s-%%s" when not using tenant.

Note that if the null-label variable label_order is truncated or extended with additional labels, this template will
need to be updated to reflect the new number of labels.
string "arn:%s:iam::%s:role/%s-%s-%s-%s-%%s" 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
identity_account_account_name The short name for the account holding primary IAM roles string "identity" 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
legacy_terraform_uses_admin If true, the legacy behavior of using the admin role rather than the terraform role in the
root and identity accounts will be preserved.
The default is to use the negations of the value of terraform_dynamic_role_enabled.
bool null 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
profile_template The template used to render AWS Profile names.
Default is appropriate when using tenant and default label order with null-label.
Use "%s-%s-%s-%s" when not using tenant.

Note that if the null-label variable label_order is truncated or extended with additional labels, this template will
need to be updated to reflect the new number of labels.
string "%s-%s-%s-%s-%s" no
profiles_enabled Whether or not to enable profiles instead of roles for the backend. If true, profile must be set. If false, role_arn must be set. bool false 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
root_account_account_name The short name for the root account string "root" no
root_account_aws_name The name of the root account as reported by AWS 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
terraform_dynamic_role_enabled If true, the IAM role Terraform will assume will depend on the identity of the user running terraform bool false no
terraform_role_name_map Mapping of Terraform action (plan or apply) to aws-team-role name to assume for that action map(string)
{
"apply": "terraform",
"plan": "planner"
}
no
