- Replace OBSERVABILITY_DATA_ROOT with per-service *_ROOT variables in docker-compose.observability.yml. - Each service root must contain config/ (mounted read-only) and data/ (mounted read-write), grouping config and state together for Portainer. - Update docs/observability-runbooks.md with the new variables, a setup script that copies repo configs into each service root, and updated backup/restore examples.

# Standalone observability stack.
|
|
#
|
|
# Run this on a host where you want Grafana, Prometheus, Loki, Alertmanager,
|
|
# Alloy and Node Exporter without the rest of Manage.
|
|
#
|
|
# Required environment variables:
|
|
# - *_ROOT directories (absolute paths) for services you want to persist
|
|
# - CERT_RESOLVER (Traefik cert resolver name)
|
|
# - GRAFANA_APP_HOST, PROMETHEUS_APP_HOST, ALERTMANAGER_APP_HOST
|
|
#
|
|
# Each service root should contain a config/ and data/ subdirectory, e.g.:
|
|
#
|
|
# /var/lib/manage/observability/prometheus/
|
|
# ├── config/
|
|
# │ ├── prometheus.yml
|
|
# │ ├── rules/
|
|
# │ └── file-sd/
|
|
# └── data/
|
|
#
|
|
# Optional environment variables:
|
|
# - TRAEFIK_ENTRYPOINT (default: websecure)
|
|
# - *_APP_NAME router/service names (defaults below)
|
|
# - all *_PORT variables for direct host ports
|
|
#
|
|
# Deploy:
|
|
# docker compose -f docker-compose.observability.yml up -d
|
|
#
|
|
# Then open Grafana at the configured host (default admin / admin).
