Trouble with Rabbit and Spring

Question

Talk about beauty?

I’m having a problem using my application with Rabbit via Docker.

Here’s what you get:

I created a Docker-Compose, it follows:

version: "3"

services:
  rabbitmq:
    image: rabbitmq:3-management
    hostname: rabbitmq
    ports:
      - "15672:15672"
      - "5672:5672"
    restart: on-failure
    networks: 
      - teste

  relay:
    build:
      context: .
      dockerfile: RelayDockerfile
    ports:
      - "8090:8090"
    restart: on-failure
    depends_on:
      - rabbitmq
      - mongodb
    environment:
      - MONGODB_URI=mongodb://camarguinho:camarguinho@mongodb:27017/
      - SPRING_RABBITMQ_PORT=5672
      - SPRING_RABBITMQ_HOST=rabbitmq
      - SPRING_RABBITMQ_USERNAME=guest
      - SPRING_RABBITMQ_PASSWORD=guest   
    networks: 
      - teste 

  mongodb:
    image: mongo:4.4.3
    environment:
      - MONGO_INITDB_DATABASE=component-db
      - MONGO_INITDB_ROOT_USERNAME=camarguinho
      - MONGO_INITDB_ROOT_PASSWORD=camarguinho
    ports:
      - "27017:27017"
    volumes:
      - ./mongod/config/mongod.conf:/etc/mongod.conf
    networks: 
      - teste

networks:
  teste:
    external:
      name: teste 

But when rotating docker-compose up, the application cannot connect to Rabbit. I put a println() - BEAUTIFUL DEBUG - to know which URL he was trying to connect to and the answer is: amqp://guest:guest@rabbitmq:5672/, just to make sure I was getting right.

I know with network_mode: host It works well because I have already tested, but I didn’t want to have to use this method where the application is in the same "network" as my machine. I wanted everything inside the Docker network.

Some solution guys?
