Docker rails elastic search

I am trying to implement elastic search in my rails web app. I am using docker. I used this link for reference. My docker-compose.yml file is:

 mysql:
  image: mysql:5.6.34
  ports:
    - "3002:3002"
  volumes_from:
    - dbdata
  environment:
    - MYSQL_ROOT_PASSWORD=root
    - MYSQL_DATABASE=dev

dbdata:
  image: tianon/true
  volumes:
    - /var/lib/mysql

web:
  build: .
  environment:
    RAILS_ENV: development
  ports:
    - '3000:3000'
  volumes_from:
    - appdata
  links:
    - "mysql"
    - elasticsearch

appdata:
  image: tianon/true
  volumes:
    - ".:/workspace"

elasticsearch:
  image: elasticsearch
  ports:
    - "9200:9200"
  ulimits:
    memlock:
      soft: -1
      hard: -1
    nofile:
      soft: 65536
      hard: 65536
  mem_limit: 1g
  cap_add:
    - IPC_LOCK
  volumes:
    - /usr/share/elasticsearch/data

When I am trying to run Student.__elasticsearch__.create_index! force:true as indicated in the above given link. I am getting following error:enter image description here

You need to set ENV for ELASTICSEARCH_URL to correct value

ELASTICSEARCH_URL="http://<ip-of-your-docker-container>:9200"

As you have linked network, you can provide as bellow

ELASTICSEARCH_URL="http://elasticsearch:9200"

Links allow you to define extra aliases by which a service is reachable from another service. Any service can reach any other service at that service’s name

If no ENV is set, your rails app will use http://localhost:9200
