# Compose override — enable Grafana Cloud export at runtime.
#
# Layer this on top of the base stack to swap the collector onto the
# Grafana Cloud dual-export config and inject the OTLP credentials. The
# base docker-compose.yml is unchanged, so plain `up` stays local-only.
#
# Usage:
#   1. Put your three Grafana Cloud values in docker/telemetry/.env.grafanacloud
#      (template: .env.grafanacloud.example). That file is gitignored.
#   2. Bring the stack up with BOTH compose files:
#        docker compose -f docker/telemetry/docker-compose.yml \
#                       -f docker/telemetry/docker-compose.grafanacloud.yaml up -d
#   3. To go back to local-only, bring the stack up with just the base file.
#
# Log mount: inherited from the base compose (./data/logs -> /var/log/xrpld).
# Both nodes' xrpld cfgs write to docker/telemetry/data/logs/<net>/debug.log,
# so no per-box remap is needed here.
