# Loki

This root renders `grafana-community/loki` chart `18.7.1` as one Loki
`3.7.4` monolithic StatefulSet in `observability`.

- The image is pinned to the reviewed amd64 digest.
- Logs use the `loki` AIStor bucket through `loki-object-storage`; no root
  credential is referenced.
- Retention is 30 days. The WAL and working data use the dedicated 5Gi
  Retain Local PV.
- Gateway, canary, caches, embedded MinIO, tests, and rule sidecars are
  disabled.
- The only client-facing service is ClusterIP port 3100.

Do not delete the PVC or bucket during rollback. Scale the StatefulSet down,
preserve its Retain volume, and investigate S3/WAL state before reapplying.
