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

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.
