@codefromthecrypt Could you kindly review this when you have some time? Thank you! |

when ready for this change (docker-compose), note this is a common port, so maybe comment it out and say "uncomment to expose the UI port"

Ok, I'll modify it when it's ready.

| ENV HEALTHCHECK_PORT=8080 |

shouldn't we check the service port 6650 (esp if we are using tcp)

I modified it to HTTP on port 8080, which is enough for the healthcheck.

ok mainly I was concerned about race condition where 8080 is ready, but service port not. If this becomes a problem we can revisit

looks like the healthcheck approach is failing on 404. you will need a valid http path https://github.com/openzipkin/zipkin/actions/runs/13084307860/job/36514939047?pr=3789 also, once done please lower the log level to warn as it will be unreadable to have info due to the health checks (examples shouldn't scroll too long due to chatty or health check in docker, we usually set to WARN) |
|
Well, I have tested it locally and it should be OK now. |
|
It seems that the error is unrelated to the changes and may be due to a network issue, could you please run it again. |
Since there is no collector-pulsar module at present, compiling docker will result in an error, so when this PR is merged, I will add
zipkin-collector-pulsarto the github actions in #3788.
