28 alert rules across 9 PrometheusRule files covering infrastructure
(Longhorn, cert-manager), data (PostgreSQL, OpenBao, OpenSearch),
storage (SeaweedFS), devtools (Gitea), identity (Hydra, Kratos),
media (LiveKit), and mesh (Linkerd golden signals for all services).
Severity routing: critical alerts fire to Matrix + email, warnings
to Matrix only (AlertManager config updated in separate commit).
Previously s3.json was embedded in the seaweedfs-filer-config ConfigMap
with hardcoded minioadmin credentials, and the config volume was mounted
at /etc/seaweedfs/ (overwriting filer.toml with its own directory mount).
- Remove s3.json from ConfigMap; fix the config volume to mount only
filer.toml via subPath so both files coexist under /etc/seaweedfs/.
- Add vault-secrets.yaml with VaultStaticSecrets that VSO syncs from
OpenBao secret/seaweedfs: seaweedfs-s3-credentials (S3_ACCESS_KEY /
S3_SECRET_KEY) and seaweedfs-s3-json (s3.json as a JSON template).
- Mount seaweedfs-s3-json Secret at /etc/seaweedfs/s3.json via subPath.
