📄 Extensive documentation is available via our GitHub Pages Docs site.

📢 We maintain the project as a truly open-source project. We maintain the project on a best effort basis. We welcome contributions from the community. Feel free to help us answering issues, reviewing PRs, or maintaining and improving the project.

📢 v5 replaces Amazon Linux 2 with Amazon Linux 2023 as default OS. Check the PR for more details and other changes.

📢 For contributions to older versions you can make a PR to the related branch, e.g. v4. We have no release process in place for older versions.

This Terraform module creates the required infrastructure needed to host GitHub Actions self-hosted, auto-scaling runners on AWS spot instances. It provides the required logic to handle the life cycle for scaling up and down using a set of AWS Lambda functions. Runners are scaled down to zero to avoid costs when no workflows are active.

Features

• Scaling: Scale up and down based on GitHub events
• Sustainability: Scale down to zero when no jobs are running
• Security: Runners are created on-demand and terminated after use (ephemeral runners)
• Cost optimization: Runners are created on spot instances
• Tailored software, hardware and network configuration: Bring your own AMI, define the instance types and subnets to use.
• OS support: Linux (x64/arm64) and Windows
• Multi-Runner: Create multiple runner configurations with a single deployment
• GitHub cloud and GitHub Enterprise Server (GHES) support.
• Org and repo level runners. enterprise level runners are not supported (yet).

Getting started

Check out the detailed instructions in the Getting Started section of the docs. On a high level, the following steps are required to get started:

• Setup your AWS account
• Create and configure a GitHub App
• Download or build the required lambdas
• Deploy the module using Terraform
• Install the GitHub App to your organization or repositories and add your repositories to the runner group(s).

Check out the provided Terraform examples in the examples directory for different scenarios.

Configuration
