Kernel-idgenerator-service unreachable despite "Deployed verticle" logs

1

Hi Community,

I am working on deploying the kernel-idgenerator-service. Previously, I was facing ModuleNotFoundException errors related to Ceylon, but I have resolved that by correctly adding the required regproc-reprocessor-ceylon-cache-repo.

Current Status: The logs are now clean (no exceptions), and the HttpServerVerticle reports as “Deployed”. However, I cannot reach the service from other internal pods (e.g., id-repo-identity-service).

The Issue: When I start the pod, the logs initialize and reach the point where HttpServerVerticle and IDGeneratorVertxApplication start, but then the logs stop moving. When I try to hit the endpoint http://kernel-idgenerator-service:8080/v1/idgenerator/uin from another pod, the request times out or fails to connect.
Logs: Here is the sequence :

logs..

My Observations:

  1. The VidPoolCheckerVerticle seems to initialize successfully.

  2. The HttpServerVerticle is marked as deployed.

  3. However, curl commands to port 8080 fail.

Question: Does the log message "Service will be started after pooling" imply that the HTTP server is holding traffic until the UIN/VID pool is fully populated? If the pool is empty or cannot connect to the DB/Queue, will the service remain unreachable on port 8080, or should it still respond to health checks?

Any insights on why the service would be unreachable despite these successful deployment logs would be helpful.
