terraform-aws-datadog-integration: An HCL repository from Cloud Posse

Terraform module to configure Datadog AWS integration.

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.

Note: At the moment this module supports a limited set of IAM policies to support Datadog integrations. More can be added as needed.

Structure

This module follows Datadog's documentation by supporting a core integration which is the minimum set of permissions needed for any Datadog integration, plus an additional integration per service which contains the additional permissions Datadog has documented are required for that service.

To make things easier, this module also implements an all integration which includes all the permissions Datadog lists under "All Permissions" as the maximal set of permissions required, so you can just set integrations = ["all"] and be done.

Installation

Include this module in your existing terraform code:

module "datadog_integration" {
  source = "cloudposse/datadog-integration/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"

  namespace                  = "eg"
  stage                      = "test"
  name                       = "datadog"
  integrations               = ["all"]
}

The DataDog integration will be linked with your configured datadog account via the provider's api_key.

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
account_specific_namespace_rules	An object, (in the form {"namespace1":true/false, "namespace2":true/false} ), that enables or disables metric collection for specific AWS namespaces for this AWS account only	`map(string)`	`null`	no
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
cspm_resource_collection_enabled	Whether Datadog collects cloud security posture management resources from your AWS account.	`bool`	`null`	no
datadog_aws_account_id	The AWS account ID Datadog's integration servers use for all integrations	`string`	`"464622532012"`	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
excluded_regions	An array of AWS regions to exclude from metrics collection	`list(string)`	`null`	no
filter_tags	An array of EC2 tags (in the form `key:value`) that defines a filter that Datadog use when collecting metrics from EC2. Wildcards, such as ? (for single characters) and * (for multiple characters) can also be used	`list(string)`	`null`	no
host_tags	An array of tags (in the form `key:value`) to add to all hosts and metrics reporting through this integration	`list(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
integrations	List of AWS permission names to apply for different integrations (e.g. 'all', 'core')	`list(string)`	n/a	yes
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
metrics_collection_enabled	Whether Datadog collects metrics for this AWS account.	`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
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
resource_collection_enabled	Whether Datadog collects a standard set of resources from your AWS account.	`bool`	`null`	no
security_audit_policy_enabled	Enable/disable attaching the AWS managed `SecurityAudit` policy to the Datadog IAM role to collect information about how AWS resources are configured (used in Datadog Cloud Security Posture Management to read security configuration metadata). If var.cspm_resource_collection_enabled, this is enabled automatically.	`bool`	`false`	no
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
