actions/actions-runner-controller
Kubernetes controller for GitHub Actions self-hosted runners
Autoscaling GitHub Actions runners natively on Kubernetes — ARC is a Kubernetes operator that manages self-hosted GitHub Actions runners as runner scale sets, scaling them up or down based on workflow demand. Runners can be ephemeral containers, enabling fast, clean scaling. Useful for teams running CI/CD on their own Kubernetes clusters instead of GitHub-hosted runners.
