| 2 | * A "guestbook" app on EKS Auto Mode that exercises the full Kubernetes |
| 3 | * container surface: |
| 4 | * |
| 5 | * - a stack-owned network + `compute: "auto"` cluster + DynamoDB table + |
| 6 | * a namespace applied as a raw manifest via `Kubernetes.Manifest` (`src/infra.ts`), |
| 7 | * - `Api` — an effectful `Kubernetes.Deployment` (bundled `main:` image source) |
| 8 | * behind an internet-facing NLB with DynamoDB bindings on the pod-identity |
| 9 | * role, plus the typed `podTemplate` escape hatch (`src/Api.ts`), |
| 10 | * - `Web` — an EXTERNAL `Kubernetes.Deployment` (registry `image:` source, no |
| 11 | * Effect runtime in the container), nginx behind its own NLB, |
| 12 | * - `SeedJob` — an inline-effect one-shot `Kubernetes.Job` (`{ run }`) that |
| 13 | * seeds the guestbook table when the batch/v1 Job is applied on deploy |
| 14 | * (`src/SeedJob.ts`). |
