The collector exits at startup whenever the Grafana Cloud stack is brought up: cannot start pipelines: failed to start "otlphttp/grafanacloud" exporter: failed to resolve authenticator "basicauth/grafanacloud": authenticator not found The developer stack passes otel-collector-filestorage.yaml as a second --config to persist filelog read offsets. The collector replaces lists on merge rather than appending them, which that file notes, and it repeats the BASE config's service.extensions -- [health_check, file_storage/filelog]. Layer the cloud overlay on top and the base config is swapped for the cloud one, whose list also carries basicauth/grafanacloud; the storage overlay still comes last, so the authenticator is dropped and the exporter that needs it cannot start. Nothing degrades: the collector refuses to start at all, so a host brought up this way exports no telemetry anywhere, local or cloud. Adds a cloud variant of the overlay naming all three extensions, mounted by docker-compose.grafanacloud.yaml over the base one so the command line is unchanged. The base variant stays as it is for stacks that do not use the cloud exporter.

# 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.
