# This assumes a Collector listening on localhost:4318; the

# http://localhost:4318 and add --driver-opt network=host.

# ── Your endpoint ──────────────────────────────────

# This uses the endpoint and auth header you saved in the
# setup guide (https://observability-on-board.vercel.app/setup/#custom). BuildKit needs a headers line even without
# authentication; a dummy value works.
