+# =============================================================================
+# 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

-# forte-drop Postgres — backup & restore runbook
-
-## What gets backed up
-
-A CronJob (`forte-drop-pg-backup`, namespace `forte-drop`) runs nightly at **02:00 UTC**:
-
-1. `pg_dump` of the `drops` database → gzip.
-2. Upload to **UpCloud Managed Object Storage**: `s3://drops/_pgbackups/forte-drop-<TS>.sql.gz`
-   (the `_pgbackups/` prefix is collision-proof: app slugs match `/^[a-z0-9][a-z0-9-]{0,62}$/`
-   and can never start with `_`).
-3. Retention: dumps older than **30 days** are pruned.
-
-S3 creds come from the `forte-drop-secrets` Secret (`S3_ENDPOINT` / `S3_KEY` / `S3_SECRET`).
-Postgres creds from `forte-drop-pg-creds` (`pgusername` / `pgpassword`).
-
-> **Object storage is the durable tier.** App data + DB backups both live in UpCloud
-> Managed Object Storage (replicated by UpCloud). The in-cluster Postgres PVC is the
-> live working copy; the nightly dump is the recovery point. The PVC carries
-> `Prune=false,Delete=false` so ArgoCD never deletes it.
-
-## Prerequisites
-
-```bash
-export KUBECONFIG=~/Downloads/dev-fd-no-svg1_kubeconfig.yaml
-# Confirm the namespace + DB pod are up:
-kubectl -n forte-drop get pods -l app.kubernetes.io/name=postgresql
-```
-
-## List available backups
-
-```bash
-# Run an ephemeral mc pod with the app's S3 creds:
-kubectl -n forte-drop run mc-list --rm -it --restart=Never \
-  --image=quay.io/minio/mc:RELEASE.2024-11-21T17-21-54Z \
-  --overrides='{"spec":{"containers":[{"name":"mc","image":"quay.io/minio/mc:RELEASE.2024-11-21T17-21-54Z","command":["sh","-c","mc alias set obj \"$S3_ENDPOINT\" \"$S3_KEY\" \"$S3_SECRET\" >/dev/null && mc ls obj/drops/_pgbackups/"],"envFrom":[{"secretRef":{"name":"forte-drop-secrets"}}]}]}}'
-```
-
-## Manually trigger a backup (before risky changes)
-
-```bash
-kubectl -n forte-drop create job --from=cronjob/forte-drop-pg-backup pg-backup-manual-$(date +%s)
-# Watch:
-kubectl -n forte-drop get jobs -l app.kubernetes.io/component=backup
-kubectl -n forte-drop logs -l app.kubernetes.io/component=backup --tail=40
-```
-
-## Restore a dump
-
-> **Destructive.** This overwrites the live `drops` database. Take a fresh manual
-> backup first (above) and confirm with whoever owns the data before proceeding.
-
-### 1. Pick the dump to restore
-
-List backups (above), choose `forte-drop-<TS>.sql.gz`.
-
-### 2. Run a restore pod that pulls the dump and pipes it into Postgres
-
-```bash
-DUMP="forte-drop-20260530T020000Z.sql.gz"   # <-- set to the chosen file
-
-kubectl -n forte-drop run pg-restore --rm -it --restart=Never \

-  --overrides='{
-    "spec": {
-      "containers": [{

-        "image": "postgres:16-alpine",
-        "command": ["sh","-c","set -euo pipefail; \
-          apk add --no-cache curl >/dev/null; \
-          # download via mc is simpler — use a 2-step instead (see note). \
-          echo placeholder"],
-        "envFrom": [

-          {"secretRef":{"name":"forte-drop-secrets"}}
-        ]
-      }]
-    }
-  }'
-```
-
-**Simpler 2-pod approach (recommended — avoids cramming mc + psql in one image):**
-
-```bash
-DUMP="forte-drop-20260530T020000Z.sql.gz"
-
-# (a) Download the dump from object storage to a local file:
-kubectl -n forte-drop run mc-get --rm -it --restart=Never \

-> The app's schema is created idempotently on boot (`CREATE TABLE IF NOT EXISTS` +
-> `ALTER TABLE ... ADD COLUMN IF NOT EXISTS` in `src/repo/pg.ts`), and `pg_dump`
-> output includes the data. For a clean restore into a fresh DB this just works.
-> To restore over an existing DB with conflicting rows, drop/recreate the `drops`
-> database first (coordinate downtime — scale the web Deployment to 0 during the
-> restore so the app isn't writing).
-
-### 3. Verify
-
-```bash
-kubectl -n forte-drop run pg-check --rm -it --restart=Never \
-  --image=postgres:16-alpine \
-  --env="PGPASSWORD=$(kubectl -n forte-drop get secret forte-drop-pg-creds -o jsonpath='{.data.pgpassword}' | base64 -d)" \
-  --command -- psql -h forte-drop-postgresql.forte-drop.svc -U drops -d drops \
-  -c "SELECT count(*) AS drops FROM drops;" -c "SELECT count(*) AS view_hits FROM view_hits;"
-```
-
-### 4. Bring the app back
-
-```bash
-# If you scaled web to 0 for the restore:
-kubectl -n forte-drop scale deploy/forte-drop --replicas=2
-```
-
-## Object data (uploaded drop files)
-
-Drop files live in `s3://drops/<slug>/...` in the same managed bucket. They are
-**not** part of the pg backup (the dump only holds metadata). Object storage is
-UpCloud-managed/replicated, so no separate file backup is configured. If a
-file-level backup is later required, mirror the bucket to a second bucket/region:
-
-```bash
-mc mirror --overwrite obj/drops/ backup-target/drops-mirror/
-```
-
-(Exclude `_pgbackups/` from the app-data mirror if you split them.)
-
-## Disaster scenarios
-
-| Scenario | Recovery |
-|---|---|
-| Postgres pod crash / reschedule | StatefulSet reattaches the PVC; ~1–2 min downtime; no data loss. |
-| PVC lost / corrupted | Recreate StatefulSet, restore latest nightly dump (above). Data since last dump is lost. |
-| Accidental `drops` table data loss | Restore latest dump; or `pg_restore` a single table from a dump. |
-| Namespace deleted | PVC has `Prune=false,Delete=false`; recreate Applications, PVC re-binds, app recovers. Backups in object storage are independent. |
-| Object storage bucket lost | UpCloud-managed (replicated). If the IAM key is rotated, update `forte-drop-secrets` (re-seal). |
