# Soteria PVC Restore Drill (backup.bstein.dev)
|
||||
|
||||
Use this runbook for a minimal production-safe restore drill after each meaningful Soteria change.
|
||||
Use this checklist after meaningful Soteria backup, restore, auth, or alerting changes.
|
||||
|
||||
## Preconditions
|
||||
## Production Restore Drill Checklist
|
||||
|
||||
- `maintenance` kustomization is reconciled and healthy in Flux.
|
||||
- `soteria` and `oauth2-proxy-soteria` Deployments are ready in `maintenance`.
|
||||
- Operator account is in Keycloak group `admin` or `maintenance`.
|
||||
- Source PVC is not ephemeral/test throwaway storage that should be excluded from backup policy.
|
||||
|
||||
## Operator Flow (UI)
|
||||
|
||||
1. Open `https://backup.bstein.dev` and sign in through Keycloak.
|
||||
2. In `PVC Inventory`, pick source namespace/PVC.
|
||||
3. Click `Backup now` and wait for success response in `Last Action`.
|
||||
4. Click `Restore`, choose a completed backup snapshot, and set:
|
||||
- `Target namespace`: destination namespace (defaults to source)
|
||||
- `Target PVC name`: unique drill PVC name (`restore-<source-pvc>-<date>`)
|
||||
5. Click `Create restore PVC`.
|
||||
|
||||
## Verification
|
||||
|
||||
1. Confirm restore target exists:
|
||||
1. Verify baseline health before touching restores.
|
||||
- `flux get kustomizations -n flux-system maintenance`
|
||||
- `kubectl -n maintenance get deploy soteria oauth2-proxy-soteria`
|
||||
2. Confirm operator access and source safety.
|
||||
- Operator must be in Keycloak group `admin` or `maintenance`.
|
||||
- Choose a real source PVC that is expected to be backed up, not a throwaway test PVC.
|
||||
3. Run the UI flow at `https://backup.bstein.dev`.
|
||||
- Sign in via Keycloak.
|
||||
- In `PVC Inventory`, select source namespace and PVC.
|
||||
- Click `Backup now` and wait for success in `Last Action`.
|
||||
- Click `Restore` and pick a completed snapshot.
|
||||
- Set `Target namespace` and unique `Target PVC name` (`restore-<source-pvc>-<date>`).
|
||||
- Click `Create restore PVC`.
|
||||
4. Validate restore output.
|
||||
- `kubectl -n <target-namespace> get pvc <target-pvc>`
|
||||
2. Confirm backup telemetry is present:
|
||||
- `kubectl -n monitoring port-forward svc/victoria-metrics-k8s-stack 8428:8428`
|
||||
- `curl -fsS 'http://127.0.0.1:8428/api/v1/query?query=max%20by%20(namespace%2Cpvc)(pvc_backup_age_hours)'`
|
||||
3. Confirm alerting input stays healthy:
|
||||
- `pvc_backup_health{namespace="<source-namespace>",pvc="<source-pvc>"} == 1`
|
||||
|
||||
## Cleanup
|
||||
|
||||
1. Remove drill PVC after validation:
|
||||
- If workload-level validation is required, attach a temporary pod and inspect expected files/data.
|
||||
5. Clean up.
|
||||
- `kubectl -n <target-namespace> delete pvc <target-pvc>`
|
||||
2. If a detached restore Longhorn volume remains, remove it in Longhorn UI/API.
|
||||
- Remove detached restore Longhorn volume from Longhorn UI/API if one remains.
|
||||
|
||||
## Alert Query Verification (`maint-soteria-*`)
|
||||
|
||||
Start a local query endpoint:
|
||||
|
||||
`kubectl -n monitoring port-forward svc/victoria-metrics-k8s-stack 8428:8428`
|
||||
|
||||
Validate each alert expression directly.
|
||||
|
||||
1. `maint-soteria-refresh-stale` (`time() - soteria_inventory_refresh_timestamp_seconds`, threshold `> 900`).
|
||||
- `curl -fsS --get 'http://127.0.0.1:8428/api/v1/query' --data-urlencode 'query=time() - soteria_inventory_refresh_timestamp_seconds'`
|
||||
- `curl -fsS --get 'http://127.0.0.1:8428/api/v1/query' --data-urlencode 'query=(time() - soteria_inventory_refresh_timestamp_seconds) > bool 900'`
|
||||
- Healthy expectation: age is below `900` and threshold query returns `0`.
|
||||
2. `maint-soteria-backup-unhealthy` (`sum((1 - pvc_backup_health{driver="longhorn"}) > bool 0) or on() vector(0)`, threshold `> 0`).
|
||||
- `curl -fsS --get 'http://127.0.0.1:8428/api/v1/query' --data-urlencode 'query=sum((1 - pvc_backup_health{driver="longhorn"}) > bool 0) or on() vector(0)'`
|
||||
- `curl -fsS --get 'http://127.0.0.1:8428/api/v1/query' --data-urlencode 'query=(1 - pvc_backup_health{driver="longhorn"}) > bool 0'`
|
||||
- `curl -fsS --get 'http://127.0.0.1:8428/api/v1/query' --data-urlencode 'query=max by (namespace,pvc) (pvc_backup_age_hours{driver="longhorn"})'`
|
||||
- Healthy expectation: unhealthy count is `0`; no series should be `1` in the per-PVC unhealthy query.
|
||||
3. `maint-soteria-authz-denials` (`sum(increase(soteria_authz_denials_total[15m])) or on() vector(0)`, threshold `> 9` for 10m).
|
||||
- `curl -fsS --get 'http://127.0.0.1:8428/api/v1/query' --data-urlencode 'query=sum(increase(soteria_authz_denials_total[15m])) or on() vector(0)'`
|
||||
- `curl -fsS --get 'http://127.0.0.1:8428/api/v1/query' --data-urlencode 'query=sum by (reason) (increase(soteria_authz_denials_total[15m]))'`
|
||||
- Healthy expectation: total remains below `10` in normal operation; spikes should map to expected `reason` labels.
|
||||
|
||||
## Failure Triage
|
||||
|
||||
- `401/403` on UI/API:
|
||||
- `401/403` on UI or API:
|
||||
- Verify oauth2-proxy group claims include `admin` or `maintenance`.
|
||||
- Restore conflict:
|
||||
- Target PVC already exists; pick a new target PVC name.
|
||||
- Freshness alert firing (`maint-soteria-refresh-stale`):
|
||||
- Target PVC already exists; choose a new target PVC name.
|
||||
- `maint-soteria-refresh-stale` firing:
|
||||
- Check Soteria pod health and `/metrics` scrape reachability from `monitoring`.
|
||||
- Unhealthy PVC alert firing (`maint-soteria-backup-unhealthy`):
|
||||
- Inspect `pvc_backup_health` and `pvc_backup_age_hours` for stale/missing backup coverage.
|
||||
- `maint-soteria-backup-unhealthy` firing:
|
||||
- Inspect `pvc_backup_health` and `pvc_backup_age_hours` to identify stale or missing backups.
|
||||
- `maint-soteria-authz-denials` firing:
|
||||
- Confirm expected OIDC groups and inspect denial `reason` labels for policy or header regressions.
