Deploy to GCP

# Update overlays (production environment for release)
# k8s/overlays/gcp-prod/kustomization.yaml → newTag: ${VERSION} (CI replaces with @sha256 digest)
kubectl apply -k k8s/overlays/gcp-prod/
kubectl rollout status deployment --all -n {namespace} --timeout=300s

Deploy to AWS

# Update overlays (production environment for release)
# k8s/overlays/aws-prod/kustomization.yaml → newTag: ${VERSION} (CI replaces with @sha256 digest)
kubectl apply -k k8s/overlays/aws-prod/
kubectl rollout status deployment --all -n {namespace} --timeout=300s

Post-Deploy Verification

Both Clouds

• /health returning 200 on all services
• /predict returning valid predictions
• /metrics being scraped by Prometheus
• Grafana dashboards showing new version
• No P1/P2 alerts in AlertManager
• HPA functioning (correct replica counts)
