This [Terraform](https://www.terraform.io/) module creates the required infrastructure needed to host [GitHub Actions](https://github.com/features/actions) self-hosted, auto-scaling runners on [AWS spot instances](https://aws.amazon.com/ec2/spot/). 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](https://philips-labs.github.io/terraform-aws-github-runner/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](./examples) directory for different scenarios.

## Configuration

Please check the [configuration](https://philips-labs.github.io/terraform-aws-github-runner/configuration/) section of the docs for major configuration options. See the Terraform module documentation for all available options.
