feat(devkit): add HOST listener and simplify port mappings#3285
Merged
Conversation
Add a HOST listener on port 29092 (container) mapped to NODE_ID*10000+9192 (host) so that host-side Kafka clients (Python, Java) can connect without /etc/hosts hacks. Previously advertised.listeners used container hostnames (node-0:9092) which are unresolvable from the host.
…TEXT/CONTROLLER exports Remove unused PLAINTEXT and CONTROLLER host port mappings since they are unreachable from the host (advertised.listeners uses container hostnames). Reuse the X9092 port slots for HOST listener and change the container-side HOST port from 29092 to 9192 to avoid confusing collision with node-2.
