Spring Boot - Kafka Issue running on Docker (Bootstrap broker localhost:9092 disconnected)

[Kevin Rapter]

I have a problem to run Spring Boot CQRS example on Docker.

When I run this command `docker-compose up --build`, all containers are up.

I got this issue when I sent any request from postman collection in my repo.

   account-cmd -> Bootstrap broker localhost:9092 disconnected
   account-query -> Bootstrap broker localhost:9092 disconnected

Here are the screenshots shown below

I think you need a bridge :
For example:
networks:
 kafka-net:
   name: kafka-net
   driver: bridge

services:
 zookeeper:
   image: docker.io/bitnami/zookeeper:3.8
   container_name: zookeeper
   
   networks:
     - kafka-net
   ports:
     - "2181:2181"
    ...
 kafka:
   image: docker.io/bitnami/kafka:3
   container_name: kafka
   networks:
     - kafka-net
   ports:
     - "9092:9092"
  environment:
     ...
   depends_on:
     - zookeeper

It didn't help me solve the issue. Can you test it?

Add name attribute like this ?
networks:
bankAccount:
 name: bankAccount
  driver: bridge
