econnrefused 127.0.0.1:5672 Rabbit-mq with docker compose

Question

I am not able to connect a node.js app with rabbit-mq server. Postgres is correctly connected. I don't know why I have a connection refused.

version: "3"
networks:
app-tier:
  driver: bridge

services:
db:
  image: postgres
  environment:
    - POSTGRES_USER=dockerDBuser
    - POSTGRES_PASSWORD=dockerDBpass
    - POSTGRES_DB=performance
  ports:
    - "5433:5432"
  volumes:
    - ./pgdata:/var/lib/postgresql/data
  networks:
    - app-tier

rabbitmq:
  image: rabbitmq:3.6.14-management
  healthcheck:
      test: ["CMD", "curl", "-f", "http://127.0.0.1:5672"]
      interval: 30s
      timeout: 10s
      retries: 5
  ports:
    - "0.0.0.0:5672:5672"
    - "0.0.0.0:15672:15672"
  networks:
    - app-tier
app:
  build: .
  depends_on:
    - rabbitmq
    - db
  links:
    - rabbitmq
    - db
  command: npm run startOrc
  environment:
    DATABASE_URL: postgres://dockerDBuser:dockerDBpass@db:5432/asdf
  restart: on-failure
  networks:
    - app-tier

It seems it's trying to connect to the host rabbitmq instead of the container rabbitmq

Answer 1

Try changing env variable CLOUDAMQP_URL to amqp://rabbitmq:5672

You can call service by it's name i.e rabbitmq.
