-1. **Create overlay value directory**: `infra/values/aks-dev/`
-2. **Add cloud-specific value files** for each component that needs one:
+1. **Cluster config**: `clusters/oci-dev.yaml` — clusterName, domain, trustedIPs, cloudProvider
+2. **Overlay value files** in `infra/values/oci-dev/`:
    - `traefik-values.yaml` — LB annotations, proxy protocol config
-   - `keycloak-values.yaml` — hostname/TLS if different
-   - `grafana-values.yaml` — hostname/datasources if different
+   - `keycloak-values.yaml` — hostname
+   - `grafana-values.yaml` — hostname
    - `gitea-values.yaml` — `storageClass` for persistence + PostgreSQL
-   - `opencost-values.yaml` — `customPricing` cost model for your cloud
-3. **Create a Kustomize overlay** (if needed): `infra/overlays/aks-prod/kustomization.yaml`
-   - Patch each Application's `valueFiles[1]` to point to `aks-prod/` files
-4. **Create a root Application**: `_app-of-apps-aks-dev.yaml` pointing to the overlay
-5. **Create Sealed Secrets** for the new cluster:
-   - `secrets/aks-dev/` — TLS certs, credentials, backup S3 config
-6. **Update `gitea-backup-s3` secret** with the new cloud's S3-compatible endpoint
-7. **Bootstrap**: `kubectl apply -f _app-of-apps-aks-dev.yaml -n argocd`
