Kubernetes Controller for GitHub Actions Runners

Actions Runner Controller (ARC) is a Kubernetes operator designed to orchestrate and scale self-hosted runners for GitHub Actions. This tool allows users to create runner scale sets that automatically adjust based on the number of workflows running within a repository, organization, or enterprise.

Key features:

• Autoscaling - Automatically scales runner instances up or down based on workflow demand.
• Container-based runners - Supports ephemeral runners that can be easily managed and deployed.
• Helm integration - Facilitates easy setup and management on Kubernetes.
• Community-driven - Developed in collaboration with the GitHub Actions team and external contributors.

ARC is an open-source project that enhances GitHub Actions by providing flexible runner management, making it suitable for teams looking to optimize their CI/CD workflows.
