atmos

Atmos is a framework for orchestrating and operating infrastructure workflows across multiple cloud and DevOps toolchains.

Use Atmos to break your architecture into reusable Components that you implement using Terraform "root modules". Then tie everything together using Stack configurations defined in YAML.

Atmos can change how you think about the Terraform code you write to build your infrastructure. Atmos is a framework that simplifies complex cloud architectures and DevOps workflows into intuitive CLI commands. Its strength in managing DRY configurations at scale for Terraform and is supported by robust design patterns, comprehensive documentation, and a passionate community, making it a versatile tool for both startups and enterprises. Atmos is extensible to accommodate any tooling, including enterprise-scale Terraform, and includes custom policy controls, vendoring, and GitOps capabilities out of the box. Everything is open source and free.

Introduction

Atmos centralizes the DevOps chain and cloud automation/orchestration into a robust command-line tool, streamlining environments and workflows into straightforward CLI commands. Leveraging advanced hierarchical configurations, it efficiently orchestrates both local and CI/CD pipeline tasks, optimizing infrastructure management for engineers and cloud architects alike. You can then run the CLI anywhere, such as locally or in CI/CD.

The Atmos project consists of a command-line tool, a Go library, and even a terraform provider. It provides numerous conventions to help you provision, manage, and orchestrate workflows across various toolchains. You can even access the configurations natively from within terraform using our terraform-provider-utils.

Cloud Posse uses this tool extensively for automating cloud infrastructure with Terraform and Kubernetes, but it can be used to automate any complex workflow.
