Which problem is this PR solving?

  • Fixes #6295: Jaeger example missing OTLP HTTP receiver on port 4318 in examples/grafana-integration/docker-compose.yaml.

Description of the changes

  • Added port 4318 under ports: for the jaeger service in the grafana-integration/docker-compose.yaml file to expose the OTLP HTTP receiver.
  • This ensures compatibility with OTLP HTTP exporters like the OpenTelemetry Collector.

How was this change tested?

  • Ran docker compose up -d in examples/grafana-integration/
  • Verified that port 4318 is exposed using docker ps and docker inspect
gokul@gokul-VMware-Virtual-Platform:~/PR/jaeger/examples/grafana-integration$ docker inspect grafana-integration-jaeger-1 | grep 4318
                "4318/tcp": [
                        "HostPort": "4318"
                "4318/tcp": {},
                "4318/tcp": [
                        "HostPort": "4318"
                        "HostPort": "4318"
  • Also validated that the port is open and responds (expected 404 for GET request):
curl -v http://localhost:4318
* Host localhost:4318 was resolved.
* IPv6: ::1
* IPv4: 127.0.0.1

* Connected to localhost (::1) port 4318
