communicating from another docker container in ECS cluster

Let's take this part of docker-compose.yml

 eurekaserver:
   image:  XXXXX
   ports:
       - "8761:8761"
  zuulserver:
    image: XXXXX
    ports:
      - "5555:5555"
      - "5556:5556"
    environment:
      PROFILE: "default"
      SERVER_PORT: "5555"
      DEBUG_PORT: "5556"
      EUREKASERVER_URI: "http://eurekaserver:8761/eureka/"
      EUREKASERVER_PORT: "8761"

In my local machine I can communicate from zuulserver to eurekaserver. I checked it via nc -z eurekaserver $EUREKASERVER_PORT, but when I try to execute nc -z eurekaserver $EUREKASERVER_PORT from inside zuulserver container in ECS cluster after importing docker images via ecs-cli compose --file docker-compose.yml up I get

nc: getaddrinfo: Name does not resolve
