If I don't provide host port in microservice, it is unable to correctly register with eureka

Hi ,
In my docker-compose file if I don't provide a host port mapping for my microservice, it is unable to register in eureka correctly as it gets registered with the server.port , but the host port is assigned randomly.

this is my docker-compose file

version: '3'
services:
eureka:
restart: always
tty: true
image: eureka_server:1.0
working_dir: /app
volumes:
- ./eureka_server:/app

- lip

products:
restart: always
image: product-service-ms:1.0

environment:
EUREKA_URI: "${EUREKA_URI}"
EUREKA_IP: "${EUREKA_IP}"
HOSTNAME: "${HOSTNAME}"

zuul-server:
restart: always

environment:
EUREKA_URI: "${EUREKA_URI}"
EUREKA_IP: "${EUREKA_IP}"
HOSTNAME: "${HOSTNAME}"

Seems that u´re using another project - not that one here (cxf-spring-cloud-netflix-docker)... So it´s not really related question ;)

But nevertheless: This registration process to Eureka is mostly done through setting the right config properties to your application.properties / application.yml file in your apps. Do you have a GitHub repo with your applications ready? You could also have a look into the projects in this repo here to get inspired. The critical props look like this:

eureka:
  client:
    serviceUrl:
      defaultZone: http://${registry.host:localhost}:${registry.port:8761}/eureka/
