# CNPG backup topology inventory
|
||
|
|
|
||
|
|
**Workplan:** RAILIANCE-WP-0016-T01
|
||
|
|
**Recorded:** 2026-07-22
|
||
|
|
**Method:** live `kubectl get cluster` + `psql` datname listing on both hosts.
|
||
|
|
|
||
|
|
## Hosts
|
||
|
|
|
||
|
|
| Host | Kubeconfig (operator workstation) | API |
|
||
|
|
| --- | --- | --- |
|
||
|
|
| CoulombCore | `~/.kube/config` | tunnel `k3s-api-coulombcore` |
|
||
|
|
| railiance01 | `~/.kube/config-hosteurope` | local / hosteurope |
|
||
|
|
|
||
|
|
## Production-of-record (POR) decisions
|
||
|
|
|
||
|
|
| Target id | Host | Cluster | Databases | POR? | Consumer / notes |
|
||
|
|
| --- | --- | --- | --- | --- | --- |
|
||
|
|
| `core-apps-pg` | CoulombCore | `apps-pg` | `apps_meta`, `core_hub`, `core_hub_staging`, `vergabe_db` | **Yes** | S5 apps (vergabe, core-hub) — only instance |
|
||
|
|
| `core-gitea-db` | CoulombCore | `gitea-db` | `gitea` | **Yes** | Legacy Gitea; still live |
|
||
|
|
| `r01-forgejo-db` | railiance01 | `forgejo-db` | `forgejo` | **Yes** | Forgejo production — only instance |
|
||
|
|
| `core-net-kingdom-pg` | CoulombCore | `net-kingdom-pg` | `interhub`, `privacyidea_db` | **Yes (dual)** | Backup both until app DSN audit confirms single host |
|
||
|
|
| `r01-net-kingdom-pg` | railiance01 | `net-kingdom-pg` | `interhub`, `privacyidea_db`, `probe` | **Yes (dual)** | Extra `probe` DB on R01 only |
|
||
|
|
| `core-state-hub-db` | CoulombCore | `state-hub-db` | `state_hub` | **Yes (dual)** | Hub may run against either instance historically |
|
||
|
|
| `r01-state-hub-db` | railiance01 | `state-hub-db` | `state_hub` | **Yes (dual)** | activity-core / local hub proximity |
|
||
|
|
|
||
|
|
### Dual-host policy
|
||
|
|
|
||
|
|
Until a consumer DSN audit proves a single POR for Net Kingdom and State Hub:
|
||
|
|
|
||
|
|
- **Backup both** Core and R01 instances (different Nextcloud prefixes:
|
||
|
|
`core-*` vs `r01-*`).
|
||
|
|
- Restore drills must name the **host** + cluster, not only the DB name.
|
||
|
|
|
||
|
|
## Out of backup scope (this workplan)
|
||
|
|
|
||
|
|
- CNPG system DB `postgres`
|
||
|
|
- Temporary drill DBs
|
||
|
|
- App media PVCs (vergage media disabled)
|
||
|
|
|
||
|
|
## Runner mapping
|

Implemented in `railiance-platform/tools/cmd/cnpg-option-a-backup` default target

list. Override with `CNPG_BACKUP_TARGETS=core-apps-pg,r01-forgejo-db`.
