Project Title

atlantis — Terraform Pull Request Automation for DevOps Teams

Overview

Atlantis is a self-hosted Go application that automates Terraform pull requests by listening for events via webhooks and executing terraform plan, import, and apply commands remotely. It enhances team collaboration on infrastructure changes and standardizes Terraform workflows.

Key Features

Runs Terraform commands in response to pull requests
Comments back on pull requests with the output of Terraform commands
Enables non-operations engineers to collaborate on Terraform changes

Use Cases

Use case 1: DevOps teams managing infrastructure as code using Terraform
Use case 2: Companies needing to standardize Terraform workflows across multiple teams
Use case 3: Open-source projects that require automated Terraform testing and deployment

Advantages

Makes Terraform changes visible to the whole team, improving collaboration
Allows non-operations engineers to participate in Terraform development
Provides a standardized approach to Terraform workflows

Limitations / Considerations

Requires self-hosting, which may involve additional infrastructure management
May have a learning curve for new users unfamiliar with Terraform or webhooks

Terragrunt: A thin wrapper for Terraform that provides extra tools for keeping your configurations DRY, working with multiple Terraform configurations, and managing dependencies. It differs from Atlantis in that it is a command-line tool rather than a pull request automation system.
Pulumi: A cloud-native infrastructure-as-code tool that supports multiple languages and integrates with Terraform. It differs from Atlantis in that it is a more comprehensive platform for infrastructure management, not just focused on Terraform.
