From Commit to Cluster: CI/CD Strategy for EKS Success
A complete CI/CD path for EKS: commit triggers validation, security checks gate builds, artifacts are promoted via Helm, and Argo CD drives progressive delivery.

Promote + MonitorCommit → verify → scan → build → package → staging → preprod → canary → prod.
- Why CI/CD is essential for speed, reliability, and rollback.
- Verify stage: linting, secrets scanning (Gitleaks), and image security (Trivy) before artifacts exist.
- Release stage: tag strategy, image + Helm chart publishing, and umbrella Helm workflows.
- CD with Argo CD, build promotion, and canary rollouts with Istio + Argo Rollouts.
