# Prometheus stack for the boilerplate.
#
# Deploy as a Coolify "Docker Compose" service or with vanilla
# `docker compose up -d` on the Hetzner observability box. The bind mount
# expects the prometheus.yml + secrets file to live alongside this file.
#
# Required files alongside this compose:
#   * prometheus.yml         — committed
#   * secrets/metrics_token  — NOT committed; operator provisions
#
# Storage: a named volume keeps tsdb data so a `compose down && up` won't
# wipe history. Retention is set to 30d which is plenty for an 8-week
# staging cycle on 32 GB RAM.
