# Observability stack — Grafana LGTM + GlitchTip
#
# Requires the main stack to be running first:
#   docker compose up -d                                    # creates archiv-net
#   docker compose -f docker-compose.observability.yml up -d
#
# To validate without starting:
#   docker compose -f docker-compose.observability.yml config

networks:
  # Shared network created by the main docker-compose.yml.
  # The observability stack joins as a peer so Prometheus can scrape
  # archive-backend by container name. The observability stack must NOT
  # attempt to create this network — it will fail with a clear error if
  # the main stack is not running yet.
  archiv-net:
    external: true

  # Internal network for observability-service-to-service traffic
  # (e.g. Grafana → Prometheus, Grafana → Loki, Grafana → Tempo).
