# Loki — log aggregation (single-binary mode, local filesystem storage).
|
|
#
|
|
# Stores compressed, indexed pod logs shipped by Promtail. Queried by the
|
|
# platform-engineer Hermes agent via the HTTP API (LogQL) and by Grafana.
|
|
#
|
|
# Storage: 20 GiB local PVC, 1-week retention enforced by the compactor.
|
|
# Service: loki.monitoring:3100 (ClusterIP, no auth — homelab).
