Murat ÖZDEMİR 6f9d0d1588 feat(infra): Standardize StorageBox permissions and refactor DB stack name

- Ensure consistent directory and file permissions on StorageBox mounts for improved container access across application and database services.
- Introduce application-specific `storagebox_uid`/`gid` variables for more granular ownership control.
- Enhance StorageBox mount reliability by adding systemd reload and remount handlers for configuration changes.
- Add root credentials to Patroni's etcd configuration for authenticated communication.
- Update all relevant documentation and deployment scripts to use the `iklimco` Docker stack name for database services.
- Re-encrypt production vault secrets to include the new etcd password.

09 — Verification Checklist (Prod)

Context

Run after a successful prod pipeline deployment.

1 — Swarm cluster health

docker node ls

Expected: 3 managers (Leader + 2 Reachable) for iklim-app-01/02/03, 3 workers (Ready) for iklim-db-01/02/03.

docker service ls --filter label=project=co.iklim

All services show REPLICAS X/X (target met).

2 — Precipitation image directory exists

ls -ld /mnt/storagebox/precipitation/images

Expected: directory exists. This must be created before iklimco_precipitation-service is deployed.

docker volume inspect iklimco_image-data

Expected: Options.device is /mnt/storagebox/precipitation/images.

3 — SWAG cert is valid

docker exec $(docker ps -q -f name=iklimco_swag) certbot certificates

Expected: *.iklim.co, VALID: XX days (Let's Encrypt, not the old manual cert).

TLS check from outside:

echo | openssl s_client -connect api.iklim.co:443 -servername api.iklim.co 2>/dev/null \
  | openssl x509 -noout -subject -dates

Expected: CN=*.iklim.co, notAfter > 2026-07-15 (cert is Let's Encrypt, not expiring old one).

4 — Public API

curl -si https://api.iklim.co/health

HTTP 2xx, no TLS errors.

5 — IP restriction working

From a non-whitelisted IP:

curl -si https://grafana.iklim.co
curl -si https://apigw.iklim.co
curl -si https://rabbitmq.iklim.co

All expected: HTTP 403.

From whitelisted IP (78.187.87.109 or 95.70.151.248):

curl -si https://grafana.iklim.co    # HTTP 200 Grafana
curl -si https://apigw.iklim.co      # HTTP 200 APISIX Dashboard
curl -si https://rabbitmq.iklim.co   # HTTP 200 RabbitMQ Management

6 — Vault not reachable externally

# From outside — must fail
curl -sk --connect-timeout 5 https://<iklim-app-01-public-ip>:8200/v1/sys/health
# Expected: connection refused or timeout

# From inside overlay — must succeed
docker exec $(docker ps -q -f name=iklimco_apisix | head -1) \
  curl -sk https://vault.iklim.co:8200/v1/sys/health
# Expected: {"sealed":false,...}

7 — cert-reloader watching

docker service logs iklimco_cert-reloader --tail 5

Expected: [cert-reloader] started, no errors.

8 — No unexpected published ports

docker service ls --format "{{.Name}}\t{{.Ports}}" \
  --filter label=project=co.iklim

Only iklimco_swag should show *:80->80/tcp, *:443->443/tcp.

9 — DB nodes running correct services

# Patroni (PostgreSQL HA) stack
docker stack services iklim-patroni
docker service ps iklim-patroni_patroni-01
docker service ps iklim-patroni_patroni-02
docker service ps iklim-patroni_patroni-03

# etcd cluster (for Patroni)
docker stack services iklim-etcd

# MongoDB replica set
docker stack services iklimco
docker service ps iklimco_mongodb-01
docker service ps iklimco_mongodb-02
docker service ps iklimco_mongodb-03

All tasks should show node names matching iklim-db-01, iklim-db-02, or iklim-db-03 with placement constraint role=db.

10 — APISIX replicas

docker service ps iklimco_apisix

Expected: 3 tasks, all Running, on different nodes.

11 — fail2ban active

docker exec $(docker ps -q -f name=iklimco_swag) fail2ban-client status

Expected: multiple jails listed.

12 — Microservice health (post-deploy)

After microservices are deployed (separate pipeline), verify via the public API:

curl -si https://api.iklim.co/v1/weather/current?lat=39&lon=35

Expected: valid JSON weather response.

⚠️ Old cert expiry reminder

The manually managed *.iklim.co cert expires 2026-07-15. SWAG's Let's Encrypt cert auto-renews every ~60 days. After first SWAG cert is confirmed valid, the manual cert in storagebox can be archived and is no longer used.
