forte-drop, forte-drop-mcp and forte-drop-postgresql lived under apps/base/
but were only ever wired into the upc-dev overlay (never listed in
apps/base/kustomization.yaml). They carry hackathon-domain hardcoded values
and must not sync to upc-prod, so they belong in the overlay alongside
dbunk-demo — per danijel.simeunovic's review on PR #18.

- git mv the three dirs into apps/overlays/upc-dev/ (history preserved)
- rewrite overlay kustomization refs from ../../base/forte-drop* to local
- repoint forte-drop-postgresql Application path
  apps/base/... -> apps/overlays/upc-dev/forte-drop-postgresql/resources

Render-verified: kubectl kustomize apps/overlays/upc-dev differs only by the
postgres path line; apps/overlays/upc-prod render byte-identical (forte-drop
never reaches prod).

+# =============================================================================
+# CONFIGURATION INSTRUCTIONS FOR AZURE DNS WITH WILDCARD CERTIFICATES
+# =============================================================================
+#
+# PREREQUISITES IN AZURE DNS PORTAL:
+# ----------------------------------
+# 1. Ensure you have an Azure DNS Zone for "forteapps.net" created in your
+#    Azure subscription. If not, create it in Azure Portal:
+#    - Search for "DNS zones" → Create → Zone name: forteapps.net
+#    - Note the Resource Group where you create it (e.g., "dns-zones-rg")
+#
+# 2. Configure NS records at your domain registrar to point to Azure DNS:
+#    - In Azure Portal → DNS zones → forteapps.net
+#    - Note the 4 NS records shown (e.g., ns1-04.azure-dns.com, etc.)
+#    - Go to your domain registrar and update the NS records to these values
+#
+# AUTHENTICATION (Service Principal - Required for UpCloud/non-Azure clusters):
+# ----------------------------------------------------------------------------
+# Since your cluster runs on UpCloud (not AKS), you must use Service Principal
+# authentication. Managed Identity only works with Azure-hosted resources.
+#
+# =============================================================================
+# SETUP: Service Principal for UpCloud Clusters
+# =============================================================================
+#
+# 1. Create Azure AD App Registration:
+#    az ad sp create-for-rbac --name cert-manager-dns --sdk-auth
+#    # Save the JSON output - you'll need appId (clientID) and password (clientSecret)
+#
+# 2. Assign DNS Zone Contributor role:
+#    az role assignment create \
+#      --role "DNS Zone Contributor" \
+#      --assignee <SERVICE_PRINCIPAL_CLIENT_ID> \
+#      --scope /subscriptions/<SUBSCRIPTION_ID>/resourceGroups/<DNS_RESOURCE_GROUP>/providers/Microsoft.Network/dnszones/forteapps.net
+#
+# 3. Create Kubernetes secret for the service principal:
+#    kubectl create secret generic azuredns-config \
+#      --namespace cert-manager \
+#      --from-literal=client-secret=YOUR_CLIENT_SECRET
+#
+# 4. Update the ClusterIssuer above with:
+#    - subscriptionID: Your Azure subscription ID
+#    - resourceGroupName: The resource group containing your DNS zone
+#    - clientID: The Service Principal appId/clientID
+#    - clientSecretSecretRef: References the secret created in step 3

+## Infrastructure Provisioning (OpenTofu)
+
+The `.tofu/` directory contains multi-cloud Kubernetes infrastructure-as-code using [OpenTofu](https://opentofu.org/). It provisions clusters on four cloud platforms (AKS, EKS, GKE, UpCloud), each with three environment tiers: **dev**, **prod**, and **workload**.
+
+### Provisioning Prerequisites {#provisioning-prerequisites}
+
+- **OpenTofu** (`tofu`) installed
+- **kubectl** installed
+- **helm** installed
+- **yq** (optional — loads cluster config from `clusters/<cluster>.yaml`)
+- Platform CLI tools:
+  - **AKS**: `az` (Azure CLI)
+  - **EKS**: `aws` (AWS CLI)
+  - **GKE**: `gcloud` (Google Cloud SDK)
+  - **UPC**: `upctl` (UpCloud CLI)
+
+### Provisioning a Cluster
+
+```bash
+# Navigate to the scripts directory
+cd .tofu/scripts
+
+# 1. Copy and fill in credentials for your platform
+cp ../configs/aks.env.example ../configs/aks.env
+# Edit ../configs/aks.env with your credentials
+
+# 2. Provision cluster (interactive — prompts before applying)
+./setup-cluster.sh aks-dev
+
+# 3. Dry-run only (plan without applying)
+./setup-cluster.sh aks-dev --plan
+
+# 4. Non-interactive (skip confirmations)
+./setup-cluster.sh aks-dev --auto
+```
+
+**Cluster name format**: `<platform>-<env>` — e.g., `aks-dev`, `eks-prod`, `gke-workload`, `upc-dev`
+
+**What `setup-cluster.sh` does**:
+1. Validates cluster name, extracts platform and environment
+2. Checks prerequisites (tofu, kubectl, helm)
+3. Loads credentials from `configs/<platform>.env`
+4. Optionally loads cluster config from `clusters/<cluster>.yaml` (via yq)
+5. Runs `tofu init` → `tofu plan` → prompts → `tofu apply`
+6. Fetches and caches kubeconfig to `private/<cluster>/kubeconfig`
+7. Waits for all nodes to reach Ready state (300s timeout)
+8. Outputs next steps: `export KUBECONFIG` + `./bootstrap.sh`
+
+### Tearing Down a Cluster
+
+```bash
+# Destroy cluster infrastructure
+./teardown-cluster.sh aks-dev
+
+# Equivalent to:
+./setup-cluster.sh aks-dev --destroy
+```
+
+### Retrieving Kubeconfig
+
+```bash
+# Get kubeconfig for an existing cluster (uses cache or platform CLI)
+./get-kubeconfig.sh aks-dev
+
+# Cached kubeconfigs stored in: private/<cluster>/kubeconfig
+```
+
+Platform-specific retrieval fallbacks:
+- **AKS**: `az aks get-credentials`
+- **EKS**: `aws eks update-kubeconfig`
+- **GKE**: `gcloud container clusters get-credentials`
+- **UPC**: `upctl kubernetes config`
+
+### Platform Credentials
+
+Each platform has a `configs/<platform>.env.example` template. Copy to `.env` and populate:
+
+| Platform | Required Variables | Optional |
+|----------|--------------------|----------|
+| **AKS** | `AZURE_TENANT_ID`, `AZURE_SUBSCRIPTION_ID` | `ARM_RESOURCE_GROUP` (defaults to cluster name) |
+| **EKS** | `AWS_PROFILE` (default: "default"), `AWS_REGION` (default: "eu-west-1") | `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY` |
+| **GKE** | `GCP_PROJECT_ID`, `GCP_REGION` (default: "europe-west4") | `GOOGLE_APPLICATION_CREDENTIALS` (SA JSON path) |
+| **UPC** | `UPCLOUD_TOKEN` | `UPCLOUD_CLUSTER_ID` (set after creation) |
+
+> **Note**: `.env` files are git-ignored. Never commit credentials.
+
+### End-to-End Workflow
+
+Full cluster lifecycle: provision → bootstrap → operate → teardown:
+
+```bash
+# 1. Provision infrastructure
+cd .tofu/scripts
+./setup-cluster.sh aks-dev
+
+# 2. Export kubeconfig (printed by setup-cluster.sh)
+export KUBECONFIG=$(pwd)/../../private/aks-dev/kubeconfig
+
+# 3. Bootstrap GitOps (ArgoCD + App-of-Apps)
+cd ../..
+./bootstrap.sh aks-dev
+
+# 4. Verify
+kubectl get applications -n argocd
+
+# ... operate cluster ...
+
+# 5. Teardown when done
+cd .tofu/scripts
+./teardown-cluster.sh aks-dev
+```

+
+### Naming Conventions
+
+- Cluster: `<prefix>-aks` / `-eks` / `-gke` (derived from platform)
+- Resource groups: `<prefix>-rg` (Azure only)
+- VPCs/Networks: `<prefix>-vpc`
+- Node groups: `<prefix>-nodes`
+- Dev prefix: `clst-dev`, Prod prefix: `clst`, Workload prefix: `clst-workload`
+
+### Provider Authentication
+
+| Platform | Auth Method | Config Source |
+|----------|-------------|---------------|
+| **AKS** | Azure CLI or env vars (`ARM_SUBSCRIPTION_ID`, `ARM_TENANT_ID`) | `configs/aks.env` |
+| **EKS** | AWS CLI profile or explicit credentials | `configs/eks.env` |
+| **GKE** | Application Default Credentials or SA JSON | `configs/gke.env` |
+| **UPC** | API token (`UPCLOUD_TOKEN`) | `configs/upc.env` |
