Opinionated, self-contained Terraform root modules that each solve one, specific problem
This is a collection of reusable AWS Terraform components for provisioning infrastructure used by the Cloud Posse reference architectures. They work really well with Atmos, our open-source tool for managing infrastructure as code with Terraform.
[!NOTE] This project is part of Cloud Posse's comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.
In this repo you'll find real-world examples of how we've implemented Terraform "root" modules as native Atmos Components for our customers. These Components leverage our hundreds of free and open-source terraform "child" modules.
The component library captures the business logic, opinions, best practices and non-functional requirements for an organization.
It's from this library that other developers in your organization will pick and choose from whenever they need to deploy some new capability.
These components make a lot of assumptions (aka "convention over configuration") about how we've configured our environments. That said, they still serve as an excellent reference for others on how to build, organize and distribute enterprise-grade infrastructure with Terraform that can be used with Atmos.
Please take a look at each component's README for specific usage.
[!TIP]
π½ Use Atmos with Terraform
To orchestrate multiple environments with ease using Terraform, Cloud Posse recommends using Atmos, our open-source tool for Terraform automation.
Watch demo of using Atmos with Terraform
Example of runningatmos
to manage infrastructure from our Quick Start tutorial.
Generally, you can use these components in Atmos by adding something like the following code into your stack manifest:
components: # List of components to include in the stack
terraform: # The toolchain being used for configuration
vpc: # The name of the component (e.g. terraform "root" module)
vars: # Terraform variables (e.g. `.tfvars`)
cidr_block: 10.0.0.0/16 # A variable input passed to terraform via `.tfvars`
Leverage our GitHub Action to automate the creation and management of pull requests for component updates.
This is done by creating a new file (e.g. atmos-component-updater.yml
) in the .github/workflows
directory of your repository.
The file should contain the following:
jobs:
update:
runs-on:
- "ubuntu-latest"
steps:
- name: Checkout Repository
uses: actions/checkout@v4
with:
fetch-depth: 1

pre-commit
HooksThis repository uses pre-commit and pre-commit-terraform to enforce consistent Terraform code and documentation. This is accomplished by triggering hooks during git commit
to block commits that don't pass checks (E.g. format, and module documentation). You can find the hooks that are being executed in the .pre-commit-config.yaml
file.
You can install pre-commit and this repo's pre-commit hooks on a Mac machine by running the following commands:
brew install pre-commit gawk terraform-docs coreutils
pre-commit install --install-hooks
Then run the following command to rebuild the docs for all Terraform components:
make rebuild-docs
[!IMPORTANT]
Deprecated Components
Terraform components which are no longer actively maintained are kept in the
deprecated/
folder.Many of these deprecated components are used in our older reference architectures.
We intend to eventually delete, but are leaving them for now in the repo.

help Help screen
help/all Display help for all targets
help/short This help short screen
