Same change as the base compose file, applied to the validation stack. The harness reaches every service via localhost, verified across the workload scripts and integration-test.sh.

# Docker Compose workload harness for telemetry validation.
|
|
#
|
|
# Runs the OTel telemetry backend only. There are no validator services here:
|
|
# - OTel Collector (traces + native OTLP metrics)
|
|
# - Tempo (trace backend + search API)
|
|
# - Prometheus (metrics)
|
|
# - Loki (log aggregation for log-trace correlation)
|
|
# - Grafana (dashboards + trace/log exploration)
|
|
#
|
|
# The validator cluster runs as host processes, not containers.
|
|
# run-full-validation.sh starts NUM_NODES (default 5) xrpld instances on
|
|
# 127.0.0.1, each with a cfg it generates inline, peered to each other via
|
|
# [ips_fixed]. They reach the collector through the published ports below and
|
|
# write their logs into the bind-mounted workdir for the file_log receiver.
|
|
#
|
|
# Usage:
|
|
# # Start the telemetry backend on its own:
|
|
# docker compose -f docker/telemetry/docker-compose.workload.yaml up -d
|
|
#
|
|
# # Or let the orchestrator start this stack and the node cluster together:
|
|
# docker/telemetry/workload/run-full-validation.sh
|
|
#
|
|
# Prerequisites (for the orchestrator, not for this stack):
|
|
# - xrpld binary built with -DXRPL_ENABLE_TELEMETRY=ON
|
|
# - Validator keys generated via generate-validator-keys.sh
|
|
#
|
|
# Image tags are pinned to the same versions as docker-compose.yml, which
|
|
# mounts these same collector, Tempo and Prometheus config files. Floating
|
|
# tags would let an upstream release change the harness result.
|
|
#
|
|
# Note: No Docker healthchecks are defined here. The orchestrator script
|
|
# (run-full-validation.sh) polls each service endpoint directly from the
|
|
# host, which avoids issues with missing curl/wget in container images.
