EKS cluster with Karpenter v1 NodePool that scales g4dn.xlarge spot instances 0..1 on demand for CUDA workflows. ARC RunnerScaleSet registers as [self-hosted, linux, amd64, cuda, gpu, t4]. Components: - terraform/ — VPC, EKS 1.31, system node group, Karpenter IAM/SQS - helm/karpenter-nodepool.yaml — v1 NodePool + EC2NodeClass for GPU spot - helm/nvidia-device-plugin-values.yaml — DS with GPU taint toleration - helm/arc-values.yaml + helm/runner-scaleset.yaml — ARC v0.9.x - bootstrap.sh — one-shot deploy - Makefile — init/apply/destroy/verify/cost-estimate Cost: ~$138/mo idle (EKS control plane + tiny system node + NAT), ~$0.027/build for a 10-minute g4dn.xlarge spot run.
