GitHub - cloudposse/terraform-aws-config: This module configures AWS Config, a service that enables you to assess, audit, and evaluate the configurations of your AWS resources.

This module enables AWS Config and optionally sets up an SNS topic to receive notifications of its findings.

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform

Example of running atmos to manage infrastructure from our Quick Start tutorial.

Usage

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

module "example" {
  source = "cloudposse/config/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"

  create_sns_topic = true
  create_iam_role  = true

  managed_rules = {
    account-part-of-organizations = {
      description  = "Checks whether AWS account is part of AWS Organizations. The rule is NON_COMPLIANT if an AWS account is not part of AWS Organizations or AWS Organizations master account ID does not match rule parameter MasterAccountId.",
      identifier   = "ACCOUNT_PART_OF_ORGANIZATIONS",
      trigger_type = "PERIODIC"
      enabled      = true
    }
  }
}

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

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
central_resource_collector_account	The account ID of a central account that will aggregate AWS Config from other accounts	`string`	`null`	no
child_resource_collector_accounts	The account IDs of other accounts that will send their AWS Configuration to this account	`set(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.

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
disabled_aggregation_regions	A list of regions where config aggregation is disabled	`list(string)`	[ "ap-northeast-3" ]	no

iam_role_organization_aggregator_arn	The ARN for an IAM Role that AWS Config uses for the organization aggregator that fetches AWS config data from AWS accounts. This is only used if create_organization_aggregator_iam_role is false. If you want to use an existing IAM Role, set the value of this to the ARN of the existing role and set create_organization_aggregator_iam_role to false.

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.
