Surfaced when bringing the stack up alongside corwins.media:
- Promtail: filter docker_sd to compose project=stack. Both stacks share
the host's docker.sock; without this, every promtail=true container
from corwins.media also gets ingested into our Loki.
- Container name conflict: corwins.media also defines a "nvidia-exporter"
container; rename ours to "stack-nvidia-exporter". Service-name DNS
("nvidia-exporter:9400") still resolves on the observability network
so the Prometheus scrape target is unchanged.
- Grafana datasources: provisioning is additive; add deleteDatasources
block so the legacy Jaeger datasource is removed from the DB.
- Trino prometheus target: /metrics requires auth (Trino rejects
unauthenticated scrapes). Drop the target until the openmetrics
catalog is wired with a shared secret. Loki still captures the
query lifecycle for the data-lake dashboard.
