actions-runner-controller is a Kubernetes controller that operates self-hosted runners for GitHub Actions on your Kubernetes cluster. With this tool you create a runner resource on Kubernetes, and it will run and operate the self-hosted runner. Self-hosted runners are helpful in scenarios where the job that your GitHub Actions runs needs to access resources that are either not accessible to GitHub cloud runners or have specific operating system and environmental requirements that are different from what GitHub provides. In those cases where you have a Kubernetes cluster, you can run your self-hosted runners as a Kubernetes pod, with the ability to scale up or down hooking into GitHub webhook events. actions-controller-runner is lightweight and scalable.
