Scalable CI/CD Infrastructure with EKS and Karpenter

on YouTube ↗18m

" summary

Centralized EKS cluster in a single CI AWS account runs GitLab CI runners with Karpenter provisioner for just‑in‑time nodes, warm pools to cut startup latency, and OIDC+service accounts for cross‑account IAM role assumption; pods get scheduling directives via Kyverno mutating policies (spot vs on‑demand, AZ spread, GPU hints), and ArgoCD with ApplicationSet automates dynamic service account and app creation from self‑service requests. Infrastructure replaces per‑account runners, scales horizontally, and cuts cost by about five times while keeping secure, auditable access.
