NATS Proxy

Healthcheck

Use healthcheck to confirm that the local HTTP process is answering. It is a process-level check, not a full bridge readiness check.

The Dockerfile uses /healthcheck as the container healthcheck:

curl --fail http://127.0.0.1:$PORT/healthcheck

Check both roles:

Terminal window
curl -fsS http://127.0.0.1:7000/healthcheck
curl -fsS http://127.0.0.1:7001/healthcheck

Healthcheck success means the Rack process is serving. It does not prove that NATS listeners are ready or that the other bridge side is reachable. To verify bridge readiness, also inspect /observability/nats and check state, bridge_inbound, and bridge_outbound.
