Docker rabbitmq doesn't work with RABBITMQ_DEFAULT_USER and RABBITMQ_DEFAULT_PASS

Question

I'm trying to run rabbitmq service with following configuration:

version: '3.9'
services:
  rabbit-mq:
    container_name: rabbitmq
    image: rabbitmq:3-management
    environment:
      RABBITMQ_DEFAULT_USER: ${RABBITMQ_DEFAULT_USER}
      RABBITMQ_DEFAULT_PASS: ${RABBITMQ_DEFAULT_PASS}
      RABBITMQ_DEFAULT_VHOST: 'test'
    ports:
      - '5672:5672'
      - '15672:15672'
    networks:
      monorepo:

  gateway:
    container_name: gateway
    environment:
      - APP_PORT=${GATEWAY_MS_PORT}
    build:
      context: .
      args:
        - APP_NAME=monorepo-project
    ports:
      - ${GATEWAY_MS_PORT}:${GATEWAY_MS_PORT}
    networks:
      monorepo:

  user-microservice:
    container_name: user-microservice
    environment:
      - APP_PORT=${USER_MS_PORT}
    build:
      context: .
      args:
        - APP_NAME=user-microservice
    ports:
      - ${USER_MS_PORT}:${USER_MS_PORT}
    networks:
      monorepo:
    depends_on:
      - user-microservice-db

  user-microservice-db:
    image: mysql:latest
    container_name: user-microservice-db
    environment:
      MYSQL_ROOT_PASSWORD: ${USER_MS_MYSQL_PASSWORD}
      MYSQL_DATABASE: ${USER_MS_MYSQL_DATABASE}
    ports:
      - ${USER_MS_MYSQL_PORT}:${INTERNAL_DB_PORT}
    networks:
      monorepo:

networks:
  monorepo:

However, rabbitmq service give me the following error:

2022-04-03 12:59:28.937375+00:00 [info] <0.1164.0> closing AMQP connection <0.1164.0> (172.31.0.5:37026 -> 172.31.0.3:5672)

2022-04-03 12:59:30.947123+00:00 [error] <0.1171.0> PLAIN login refused: user 'guest' - invalid credentials

Without default user and pass it works as expected. I've been searching for resolve last couple of days and have tried all suggestions from google.

Also, with my RABBITMQ_DEFAULT_USER and RABBITMQ_DEFAULT_PASS I can login into managment plugin without any problem.

My .env file:

#RABBITMQ CONFIG
RABBITMQ_DEFAULT_USER=monorepo
RABBITMQ_DEFAULT_PASS=monorepo
RABBITMQ_PORT=5672
RABBITMQ_URL=rabbitmq
RABBITMQ_QUEUE=users

Answer 1

After 3.8 the environment variables that you are using are no longer supported.

WARNING: As of RabbitMQ 3.9, all of the docker-specific variables listed below are deprecated and no longer used. Please use a configuration file instead; visit rabbitmq.com/configure to learn more about the configuration file. For a starting point, the 3.8 images will print out the config file it generated from supplied environment variables.

Use something like this in /etc/rabbitmq/definitions.json:

{
 "rabbit_version": "3.9",
  {
   "name": "test12",
   "password_hash": "kI3GCqW5JLMJa4iX1lo7X4D6XbYqlLgxIs30+P6tENUV2POR,
   "hashing_algorithm": "rabbit_password_hashing_sha256",
   "tags": "administrator"
  }
 ],
 "vhosts": [
  {
   "name": "\/"
  },
 ],
 "permissions": [
  {
   "user": "local_jobs",
   "vhost": "\/",
   "configure": ".*",
   "write": ".*",
   "read": ".*"
  }
 ],
 "parameters": [],
 "policies": [],
 "queues": [],
 "exchanges": [],
 "bindings": []
}

Then add ./rabbitmq/definitions.json:/etc/rabbitmq/definitions.json:ro to your volumes in your docker-compose.yaml.

The username and password is test12.

I don't know why, but default_pass doesn't appear in /etc/rabbitmq.conf. Solution for me was:

• delete environments
• mkdir ./rabbit_config
• touch ./rabbit_config/rabbitmq.conf
• put in ./rabbit_config/rabbitmq.conf:

default_user = username
default_pass = password

• add to docker-compose.yml:

volumes:
      - ./rabbit_config/rabbitmq.conf:/etc/rabbitmq/conf.d/advanced.conf

• docker-compose down & docker-compose up -d

And username, password became valid credentinals.

P.S. On top of that, environment has just started work with no reason
