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.
<details> <summary>Watch demo of using Atmos with Terraform</summary> <img src="https://github.com/cloudposse/atmos/blob/master/docs/demo.gif?raw=true"/> Example of running <a href="https://atmos.tools"><code>atmos</code></a> to manage infrastructure from our <a href="https://atmos.tools/quick-start/">Quick Start</a> tutorial. </detalis>

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.
