# Centralized observability stack for VerifyWise managed deployments.
#
# This file is INTENTIONALLY separate from the application compose files
# (docker-compose.yml / .override / .prod). Deploy it on a dedicated
# monitoring VM. Every managed VerifyWise deployment then pushes OpenTelemetry
# metrics + logs to this VM (configured per deployment via SuperAdmin →
# Settings → Monitoring), authenticating with an RS256 token.
#
# Flow:
#   VerifyWise services --(OTLP + Bearer token)--> otel-ingress (nginx, verifies
#     token) --> otel-collector --> Prometheus (metrics)
#                               \--> Loki        (logs)
#   Grafana visualizes both, grouped by the `deployment` label.
#
# Usage on the VM:
#   docker compose -f docker-compose.observability.yml up -d
#
# The ingress binds 4318 to localhost; front it with a TLS reverse proxy (your
# own nginx / Certbot) so deployments reach it over HTTPS. Do the same for
# Grafana (3001), and set GRAFANA_ADMIN_PASSWORD.

version: "3.9"

services:
  # Auth-gated ingress. Terminates HTTP :4318 for deployments, verifies each
  # deployment's RS256 push token, and forwards valid pushes to the internal
  # collector. It mounts only the PUBLIC key — the private signing key stays on
  # the VerifyWise side where tokens are minted, never here. See
  # observability/nginx/{nginx.conf,auth.js} and observability/README.md.
