Ephemeral CI runners without Kubernetes overhead for bare metal and macOS Apple Silicon.

Strengths

•Supports Tart for macOS VMs, solving Apple Silicon CI pipeline isolation needs.
•No Kubernetes dependency reduces operational complexity for small teams on bare metal.

Weaknesses

•Smaller community ecosystem compared to established Kubernetes-based Actions Runner Controller projects.
•Managing VM images manually adds maintenance overhead versus fully managed CI services.

Post Description

I needed isolated CI runners for my desktop CAD app (Qt/C++/Rust, three platforms) and didn't want to set up Kubernetes just for that. So I built gha-outrunner - which provisions a fresh Docker container, KVM/QEMU VM, or Tart macOS VM for each job, then destroys it when done. It uses GitHub's scaleset API so it works as an autoscaling runner group. Written in Go, MIT licensed.

Happy to answer questions.
